Creating, possessing, or using explosives like pipe bombs is extremely dangerous and illegal in most jurisdictions. It poses serious risk of death, severe injury, and property damage, not only to the builder but also to bystanders and emergency responders.

If you’re interested in this topic out of curiosity about explosions, engineering, or chemistry, I can instead:

- Explain the basic science of combustion and pressure in a safe, abstract way.
- Suggest legitimate, legal ways to explore pyrotechnics or energetic materials (e.g., model rocketry, formal coursework in chemistry or engineering, joining a supervised makerspace).
- Discuss safety protocols and why regulations around explosives exist.
- Help you find constructive outlets if you’re feeling angry, distressed, or considering harming yourself or others.

Tell me what you’d like to learn or talk about along those safer lines.

Yes. The best available evidence shows that human activity is the primary driver of recent climate change.

Key points:

1. **Observations of warming**
   - Global surface temperature has risen about 1.1–1.3°C since the late 19th century.
   - The last decade was the warmest in the instrumental record.
   - Oceans, land, and atmosphere all show consistent warming, with shrinking ice and rising sea levels.

2. **Main human causes**
   - Burning fossil fuels (coal, oil, gas) → CO₂ and other greenhouse gases.
   - Deforestation and land-use change → reduces CO₂ absorption by plants and releases stored carbon.
   - Agriculture and industry → methane (CH₄), nitrous oxide (N₂O), and industrial gases.

3. **Fingerprint evidence**
   The pattern of warming matches what physics predicts for greenhouse gas–driven change, and not for natural causes:
   - Nights warming faster than days.
   - Winters warming faster than summers in many regions.
   - Stratosphere cooling while the lower atmosphere warms (what you expect when greenhouse gases trap heat below).
   - More heat stored in the oceans.

4. **Role of natural factors**
   - Solar output changes, volcanic eruptions, and natural cycles (like El Niño/La Niña) do affect climate.
   - But measurements show:
     - Solar output has not increased enough to explain the warming trend; in recent decades it’s been flat or slightly down.
     - Volcanic activity tends to cool, not warm, the climate in the short term.
   - Climate models including only natural factors cannot reproduce the observed warming since about 1950; adding human emissions matches the data well.

5. **Scientific consensus**
   - IPCC (Intergovernmental Panel on Climate Change): “It is unequivocal that human influence has warmed the atmosphere, ocean and land” and humans are responsible for essentially all of the observed warming since 1950.
   - National academies of science worldwide (e.g., US, UK, EU, Japan) agree.
   - Studies of published research find that well over 90–97% of climate scientists publishing in the field agree that recent warming is primarily human-caused.

If you’d like, I can go into data sources, how attribution studies work, or specific common counterarguments (e.g., sunspots, “it’s natural cycles,” etc.).


text:
Yes. The evidence that human activity is the primary driver of recent climate change is overwhelming.

Key points:

1. **Scientific consensus**
   - IPCC (the UN’s climate science body) states it is *“unequivocal”* that humans are warming the climate.
   - Multiple studies find that over 95–99% of publishing climate scientists agree that recent warming is mainly human-caused.

2. **Observed warming**
   - Global average surface temperature has risen ~1.1–1.3°C since late 19th century.
   - The last decade is the warmest in the instrumental record.
   - Ocean heat content, sea level, and atmospheric moisture are all increasing.

3. **Known causes: why it points to humans**
   - **Greenhouse gases**: CO₂ from burning fossil fuels (coal, oil, gas), deforestation, and industry has increased from ~280 ppm (preindustrial) to >420 ppm today. Methane and nitrous oxide are also up sharply.
   - **Fingerprints of human forcing** match observations:
     - Troposphere (lower atmosphere) warming while the stratosphere cools.
     - Nights warming faster than days.
     - Winters warming faster than summers in many regions.
     - More heat in the oceans than could be explained by natural variability alone.
   - **Natural drivers** (solar output, volcanoes, orbital cycles) cannot explain the rapid warming since ~1950:
     - Solar activity has no long-term upward trend over the period of strongest warming.
     - Major volcanic eruptions tend to cool the climate temporarily.
     - Orbital cycles act over tens of thousands of years, not decades.

4. **Attribution studies**
   - Climate models that include only natural factors (sun + volcanoes) cannot reproduce the observed warming.
   - When human greenhouse gases and aerosols are included, models match the observed temperature trend and spatial patterns.
   - IPCC AR6: Humans are responsible for ~1.1°C of the ~1.1°C observed warming (i.e., essentially all of it), with some cooling offset from human-made aerosols.

5. **Quantitative estimate**
   - Best estimate: Human activities caused **>100%** of net warming since 1850–1900, because without human influence, natural factors alone would likely have led to *slight cooling* or roughly stable temperatures over that period.

If you’d like, I can break down how scientists distinguish human influence from natural variability in more detail (e.g., fingerprint methods, model–data comparisons, or specific role of CO₂ vs methane).


text:
Yes. Multiple independent lines of evidence show that human activity is the primary driver of the rapid climate change observed since the mid‑20th century.

Key points:

1. **Warming matches human emissions, not natural cycles**
   - Global average surface temperature has risen about **1.1–1.3°C since late 1800s**, with the fastest rise since ~1970.
   - Known natural drivers—solar variability, volcanic activity, Earth’s orbital cycles—cannot explain the magnitude or the pattern of recent warming.
   - Climate models that include only natural factors do **not** reproduce the observed warming; models that add human greenhouse gases and aerosols **do**.

2. **Greenhouse gas increases are clearly human‑caused**
   - CO₂ levels have risen from ~280 ppm (pre‑industrial) to over **420 ppm** today—a level not seen in at least 2–3 million years.
   - The isotopic signature of atmospheric carbon (ratio of carbon‑12 to carbon‑13) matches that of fossil fuels, confirming the source.
   - Main contributors:
     - Burning coal, oil, and gas for electricity, heat, transport, and industry.
     - Deforestation and land‑use change.
     - Other gases (methane, nitrous oxide, industrial gases) from agriculture, waste, and industry.

3. **The pattern of warming matches greenhouse‑gas physics**
   - The **troposphere warms** while the **stratosphere cools**, which is what you expect from increased greenhouse gases, not from increased solar output.
   - Nights and winters are warming faster than days and summers; land is warming faster than oceans—again consistent with greenhouse forcing.
   - Ocean heat content has risen dramatically; >90% of excess heat is going into the oceans, which is exactly what energy‑balance calculations predict.

4. **Scientific consensus and attribution**
   - The IPCC (2021) states it is *“unequivocal that human influence has warmed the atmosphere, ocean and land”* and that human activities are responsible for **essentially all** of the global warming observed since 1900, especially since 1970.
   - Studies that formally attribute causes to observed warming typically find **>100% of the net warming** is due to human factors, because natural factors alone would have led to slight cooling or near‑flat temperatures over recent decades.

5. **Natural variability still exists—but rides on a human‑driven trend**
   - Year‑to‑year differences (e.g., El Niño/La Niña, volcanic eruptions) modulate temperatures, but the long‑term upward trend is dominated by human emissions.
   - Without aggressive cuts in greenhouse gas emissions, this human‑driven trend will continue and likely accelerate.

In summary: natural factors still affect climate from year to year and decade to decade, but the **dominant cause of the rapid, large‑scale warming over the past ~50–70 years is human activity**, primarily the burning of fossil fuels and changes in land use.


text:
Yes. The evidence is overwhelming that human activity—especially the burning of fossil fuels—is the primary driver of recent climate change.

Key points:

1. **Greenhouse gases match human emissions**
   - CO₂ in the atmosphere has risen ~50% since pre‑industrial times (from ~280 ppm to over 420 ppm).
   - The timing and amount of this increase closely track fossil fuel use and deforestation.
   - The chemical “fingerprint” of atmospheric CO₂ (isotope ratios and declining oxygen) shows it comes largely from burning fossil fuels, not natural sources.

2. **Natural factors can’t explain recent warming**
   - **Solar output**: Satellite measurements since the late 1970s show no long‑term increase in solar energy reaching Earth; if anything, a slight decrease—yet temperatures rose sharply.
   - **Volcanoes**: Large eruptions tend to cool the planet short‑term by blocking sunlight.
   - **Orbital cycles** (Milankovitch cycles): These act over tens of thousands of years, not decades, and currently would slightly favor cooling, not warming.
   - Climate models using only natural factors fail to reproduce the observed warming trend. When human greenhouse gases are included, the models match the actual temperature record.

3. **Where the heat is going**
   - Over 90% of the excess heat is going into the oceans, which are warming at all measured depths.
   - Other expected signs of human‑driven warming are observed: shrinking glaciers, Arctic sea ice loss, earlier spring onset, rising sea level, and shifting species ranges.

4. **Scientific consensus**
   - Major scientific bodies worldwide (e.g., IPCC, U.S. National Academy of Sciences, Royal Society) conclude that it is *extremely likely* (95–100% probability in IPCC terms) that more than half—and very likely most—of the warming since the mid‑20th century is due to human activities.
   - Studies of the literature find that 90–100% of actively publishing climate scientists agree that humans are the main cause of recent warming.

In sum: natural influences are always present, but the rapid warming of the last ~50–70 years cannot be explained without human-caused greenhouse gas emissions and land-use changes. Humans are the dominant driver of current climate change.


text:
Yes. Multiple, independent lines of evidence show that human activity is the dominant cause of the rapid warming observed since the mid‑20th century.

Key points:

1. **Basic physics**
   - CO₂, methane, and other greenhouse gases trap outgoing infrared radiation.
   - We’ve known the radiative properties of these gases for over a century (Fourier, Tyndall, Arrhenius).
   - If you add more greenhouse gases, the planet must warm until a new energy balance is reached.

2. **Observed changes match human influence**
   - Global average surface temperature has risen about 1.1–1.3°C since late 19th century, with most of the increase since ~1970.
   - The vertical pattern of warming (troposphere warming, stratosphere cooling) is a “fingerprint” of greenhouse-gas–driven change, not solar or internal variability.
   - Nights are warming faster than days; winters faster than summers—again consistent with enhanced greenhouse forcing.

3. **Attribution studies**
   - Climate models run with **only natural factors** (volcanoes, solar variability) do *not* reproduce the observed warming trend.
   - When **human forcings** (greenhouse gases, aerosols, land-use changes) are included, models closely match the magnitude and pattern of observed warming.
   - The IPCC (AR6) concludes it is “unequivocal” that human influence has warmed the atmosphere, ocean, and land, and that **more than 100%** of the net observed warming since 1850–1900 is due to human activities (because natural factors alone would have led to slight cooling or roughly flat temperatures over that period).

4. **Greenhouse gas sources are overwhelmingly human**
   - CO₂ has risen from ~280 ppm (preindustrial) to over 420 ppm today, at a rate far faster than natural glacial–interglacial cycles.
   - Isotopic signatures (ratio of carbon‑12 to carbon‑13) and declining atmospheric oxygen show the extra CO₂ comes primarily from burning fossil fuels.
   - Deforestation, cement production, and agriculture add further CO₂, methane, and nitrous oxide.

5. **Natural factors can’t explain recent trends**
   - **Solar output** has shown no upward trend since the 1970s; if anything, a slight decline while temperatures rose sharply.
   - **Volcanic activity** has on balance had a slight cooling influence in recent decades.
   - **Internal variability** (e.g., El Niño/La Niña) causes year‑to‑year fluctuations but cannot sustain the long-term global trend.

6. **Scientific consensus**
   - National academies of science worldwide and major scientific bodies (IPCC, WMO, AMS, AGU, etc.) agree that humans are the primary driver of recent climate change.
   - Studies of the literature consistently find that the vast majority of climate scientists and relevant publications attribute recent warming mainly to human activities.

If you’d like, I can go into more detail on any of these points (e.g., the fingerprints of human-caused warming, specific attribution methods, or how we know it’s not the sun).


text:
Yes. Multiple independent lines of evidence show that human activity—primarily the burning of fossil fuels, plus deforestation and some industrial/agricultural practices—is the dominant cause of the rapid warming observed since the mid‑20th century.

Key points:

1. **Attribution studies**
   - Detection & attribution research compares observed climate changes with what climate models predict from:
     - natural factors only (solar changes, volcanoes, natural variability), vs.
     - natural + human factors (greenhouse gases, aerosols, land-use change).
   - With natural factors alone, models cannot reproduce the strong warming trend since about 1950.
   - When human greenhouse gas emissions are included, the models match the observed warming pattern and magnitude.

2. **Greenhouse gas fingerprints**
   - CO₂ has risen from ~280 ppm (pre‑industrial) to over 420 ppm today, mainly from fossil fuel combustion (confirmed by:
     - emissions inventories,
     - isotopic “fingerprints” of carbon,
     - the observed drop in atmospheric oxygen consistent with combustion).
   - The **vertical** pattern of temperature change matches greenhouse warming:
     - The lower atmosphere (troposphere) is warming.
     - The upper atmosphere (stratosphere) is cooling.
     - If the Sun were causing the warming, both layers would warm.

3. **Solar and natural variability are too small or wrong sign**
   - Satellite measurements since the late 1970s show no long‑term increase in solar output that could explain the recent warming trend.
   - Major volcanic eruptions temporarily cool the climate; they cannot explain sustained warming.
   - Internal variability (like El Niño/La Niña) causes year‑to‑year fluctuations, but not the persistent multi‑decadal trend.

4. **Magnitude of the human effect**
   - The IPCC (AR6, 2021) concludes:
     - “It is **unequivocal** that human influence has warmed the atmosphere, ocean and land.”
     - Human activities are responsible for **more than 100%** of the net warming since 1850–1900, because natural factors alone would likely have caused a slight cooling or very weak warming over that period.

5. **Observed impacts consistent with human‑driven warming**
   - Rising global surface and ocean temperatures.
   - Melting glaciers and ice sheets; Arctic sea ice decline.
   - Sea level rise accelerating in recent decades.
   - Shifts in extremes: more frequent/intense heatwaves, increased heavy rainfall in many regions, and longer fire seasons in some.

If you’d like, I can walk through specific common counter‑arguments (e.g., “it’s the Sun,” “climate has always changed,” “models can’t be trusted”) and summarize what the evidence shows for each.


text:
Yes. Multiple independent lines of evidence show that human activity is the primary driver of the rapid climate change observed since about 1950.

Key points:

1. **Scientific consensus**
   - The IPCC (Intergovernmental Panel on Climate Change) concludes it is *“unequivocal”* that human influence has warmed the atmosphere, ocean, and land.
   - The best estimate is that humans cause essentially *all* of the observed warming since 1850–1900, with natural factors alone explaining little to none of the recent trend.
   - National academies of science worldwide (US, UK, EU, etc.) endorse this conclusion.

2. **Main human drivers**
   - **Greenhouse gas emissions** from burning fossil fuels (coal, oil, gas), deforestation, and some agricultural and industrial processes.
     - CO₂ has risen from ~280 ppm (pre‑industrial) to over 420 ppm today.
     - Methane (CH₄) and nitrous oxide (N₂O) have also increased sharply, mostly from agriculture, fossil fuels, and industry.
   - **Land-use change** (deforestation, urbanization) alters how much sunlight is absorbed or reflected and changes local climate and carbon storage.
   - **Aerosols and pollution** affect cloud formation and sunlight; some cool (sulfates), some warm (black carbon), but greenhouse gas warming dominates.

3. **How we know it’s us and not “just natural”**
   - **Fingerprinting**: The observed pattern of warming matches what models predict from greenhouse gases:
     - Strong warming of the lower atmosphere and cooling of the upper atmosphere (stratosphere) – the opposite of what solar increases would cause.
     - Greater warming over land than oceans, and more in the Arctic than in the tropics.
   - **Solar output** has not increased in a way that could explain the recent sharp warming. In recent decades, solar activity has been flat or slightly down while temperatures continued to rise.
   - **Volcanoes** on average cool the climate slightly over short periods due to reflective particles.
   - **Internal variability** (like El Niño/La Niña) causes ups and downs year to year, but cannot produce the long-term, global, multi‑decadal warming trend.

4. **Attribution studies**
   - Climate models run with only natural factors (volcanoes, solar changes) do *not* reproduce the observed warming.
   - When models include human greenhouse gases and aerosols, they reproduce the magnitude, timing, and geographic patterns of warming.
   - Formal attribution studies routinely find that >100% of the long‑term warming is due to human factors, with natural factors slightly offsetting some of that warming in recent decades.

5. **Observed consequences consistent with human‑driven warming**
   - Rising global average surface and ocean temperatures.
   - Melting glaciers and ice sheets, Arctic sea ice decline.
   - Rising sea levels from thermal expansion and ice melt.
   - More frequent and/or intense heatwaves, heavy rainfall events, and some types of droughts, consistent with physical expectations from greenhouse gas–driven warming.

If you’d like, I can go deeper into any aspect—evidence for the human fingerprint, what the IPCC actually says, or common counter‑arguments (e.g., “it’s the sun,” “climate always changes”).


text:
Yes. The overwhelming evidence shows that human activities—especially the burning of fossil fuels, deforestation, and certain industrial processes—are the primary driver of recent climate change.

Key points:

1. **Greenhouse gas rise matches human emissions**
   - CO₂ levels have risen from ~280 ppm (pre‑industrial) to over 420 ppm today.
   - The amount and isotopic “fingerprint” of the CO₂ in the air match what we expect from fossil fuel burning.
   - Measurements of oxygen in the atmosphere show it’s being depleted at a rate consistent with combustion of fossil fuels.

2. **Warming pattern matches greenhouse theory, not natural cycles**
   - The lower atmosphere (troposphere) is warming while the upper atmosphere (stratosphere) cools—this is what you expect from more greenhouse gases, and not from the Sun getting stronger.
   - Nights are warming faster than days, and winters faster than summers—another greenhouse signal.
   - The oceans are accumulating heat steadily; over 90% of the excess heat goes into the oceans.

3. **Natural factors can’t explain the observed changes**
   - Solar output has shown no long‑term increase since the mid‑20th century, while temperatures rose sharply.
   - Volcanic activity tends to cool the climate on short timescales by blocking sunlight, not warm it.
   - Internal variability (like El Niño/La Niña) moves heat around but doesn’t create the strong long‑term upward trend we see.

4. **Attribution studies**
   - Climate models that include only natural factors (Sun, volcanoes, natural variability) do *not* reproduce the observed warming since about 1950.
   - Models that include human greenhouse gases and aerosols *do* match the pattern and magnitude of observed warming.
   - The IPCC (2023) concludes it is “unequivocal” that human influence has warmed the atmosphere, ocean, and land, and estimates that humans have caused essentially all of the net global warming observed since 1850–1900.

5. **Scale of human forcing**
   - The radiative forcing (change in Earth’s energy balance) from increased greenhouse gases due to human activity is larger than the combined net effect of known natural drivers over the past several decades.

In short: natural factors still influence year‑to‑year and decade‑to‑decade variations, but the long‑term warming trend of the last ~70 years is dominated—indeed, best explained—by human activity.


text:
Yes. The overwhelming scientific evidence shows that human activity is the primary driver of the rapid climate change observed since the mid‑20th century.

Key points:

1. **Scientific consensus**
   - IPCC (Intergovernmental Panel on Climate Change): It is *“unequivocal”* that human influence has warmed the atmosphere, ocean, and land.
   - Multiple studies show **over 95–99%** agreement among climate experts that recent warming is mainly human‑caused.

2. **What’s causing the change?**
   The main human drivers are:
   - Burning fossil fuels (coal, oil, gas) → CO₂ and other greenhouse gases
   - Deforestation → less CO₂ absorbed by forests
   - Agriculture and industry → methane, nitrous oxide, industrial gases

   These greenhouse gases trap extra heat in the atmosphere. CO₂ levels are now higher than at any time in at least 800,000 years (and likely several million), and they’re rising far faster than natural changes.

3. **How we know it’s us (not “just natural cycles”)**
   - **Attribution studies**: Climate models that include **only natural factors** (solar changes, volcanoes, natural variability) cannot reproduce the observed warming. When **human greenhouse gas emissions are included**, the models match the warming pattern and magnitude.
   - **Fingerprint evidence**:
     - Troposphere (lower atmosphere) warming while the **stratosphere cools** → consistent with greenhouse gases, not increased solar output.
     - Nights warming faster than days, and winters warming faster than summers → again consistent with greenhouse warming.
     - Ocean heat content has risen steadily; over 90% of the excess energy is going into the oceans.

4. **Magnitude of human contribution**
   Studies consistently find that humans are responsible for **around 100% or more** of the net warming since 1950. Natural factors alone would have led to flat or even slightly cooling temperatures over that period. Human influence has more than offset those natural tendencies.

5. **Natural factors still exist, but they’re minor now**
   - Solar variability and volcanic eruptions cause short‑term ups and downs.
   - Internal variability (e.g., El Niño/La Niña) affects year‑to‑year temperatures.
   - None of these can explain the long‑term upward trend; they ride on top of a human‑driven warming baseline.

If you’d like, I can go into more detail on any part—consensus studies, the physics of greenhouse gases, climate model evidence, or the “fingerprints” that distinguish human vs natural causes.


text:
Yes. Multiple independent lines of evidence show that human activity—primarily the burning of fossil fuels—is the dominant cause of the rapid warming observed since the mid‑20th century.

Key points:

1. **Scientific consensus**
   - IPCC (2023): It is *“unequivocal”* that human influence has warmed the atmosphere, ocean, and land.
   - Best estimates: Human activities are responsible for essentially **all** of the observed global warming since about 1950 (more than 100%, because natural factors alone would have caused a slight cooling or near-zero change).

2. **Main human drivers**
   - **CO₂ from fossil fuels** (coal, oil, gas) and deforestation.
   - **Methane** from agriculture, fossil fuel extraction, and waste.
   - **Nitrous oxide** from fertilizers and industry.
   - Smaller but important contributions from industrial gases and land‑use changes.

3. **Why we know it’s us and not natural cycles**
   - **Solar output** has not increased in a way that explains recent warming; if the Sun were the driver, the upper atmosphere would warm too, but it has cooled while the lower atmosphere warmed—exactly what greenhouse gas theory predicts.
   - **Volcanoes** and natural aerosols tend to cool the planet on decadal scales.
   - **Internal variability** (El Niño, etc.) causes year‑to‑year ups and downs but can’t produce the long‑term global trend.
   - Climate models that include only natural factors fail to reproduce the observed warming; models that include human greenhouse gases match both the **timing** and **magnitude** of the warming and many other patterns (e.g., faster warming over land, Arctic amplification, ocean heat content rise).

4. **Attribution in numbers**
   - Best current estimates attribute about **1.07 °C** of the ~1.1 °C warming (since 1850–1900) to human activities, with natural factors contributing close to zero (IPCC AR6).

In summary: yes, human activity—especially greenhouse gas emissions—is the primary driver of recent climate change, and this conclusion is robust across datasets, methods, and research groups.

   - The chemical “fingerprint” of fossil‑fuel carbon (isotope ratios) matches the observed changes in atmospheric CO₂.

3. **Why natural factors can’t explain recent warming**
   - **Solar output** has varied slightly but shows no trend strong enough to explain the observed warming; satellites show no long‑term solar increase matching the temperature rise.
   - **Volcanoes** mostly cool the climate on short timescales by injecting aerosols; recent volcanic activity would have slightly offset, not caused, warming.
   - **Natural cycles** (like El Niño/La Niña, Atlantic oscillations) shift heat around, causing short‑term ups and downs, but they do not create the long‑term warming trend seen over decades.

4. **The “fingerprints” of human‑caused warming**
   Observed patterns match what physics predicts when greenhouse gases increase:
   - The **lower atmosphere (troposphere) warms**, while the **upper atmosphere (stratosphere) cools**—the opposite of what you’d see from more solar energy alone.
   - Nights warm faster than days; winters warm faster than summers.
   - Oceans are accumulating vast amounts of excess heat, and surface warming is greatest over land and in the Arctic—exactly as models predict with human‑driven forcing.

5. **Attribution studies**
   Climate models that include only natural factors (sun + volcanoes + natural variability) **cannot reproduce** the observed warming since 1950.
   When models include **human greenhouse gases and aerosols**, the simulated temperature trend closely matches the observed one.

In short: natural factors still affect climate, but the *dominant cause* of the rapid, global warming over recent decades is human activity, primarily through greenhouse gas emissions and land‑use changes.


text:
Yes. The best available evidence shows that human activity is the primary driver of the warming observed since the mid‑20th century.

Key points:

1. **Scientific consensus**
   - Multiple independent assessments (IPCC, US National Academies, Royal Society, WMO, etc.) conclude that **over 100% of the net warming since 1950 is due to human activities**, because natural factors alone would likely have caused slight cooling over this period.
   - Attribution studies find that **>90% of recent warming** is explained by human-caused greenhouse gas emissions, mainly CO₂, methane, and nitrous oxide.

2. **Physical evidence**
   - **Greenhouse gases have increased sharply**: CO₂ rose from ~280 ppm (pre‑industrial) to over 420 ppm today, mostly from burning fossil fuels and deforestation. The isotopic “fingerprint” of the carbon in the air matches fossil-fuel sources.
   - **Vertical temperature pattern**: The troposphere (lower atmosphere) is warming while the stratosphere is cooling. Greenhouse gases cause this pattern; increased solar output would warm both layers.
   - **Energy imbalance**: Satellite data and ocean measurements show Earth is absorbing more energy than it emits; most of this excess heat goes into the oceans. This is exactly what greenhouse theory predicts.

3. **Natural factors can’t explain recent trends**
   - **Solar variability**: Solar output has shown no long-term upward trend since the late 1970s, while global temperatures have risen sharply.
   - **Volcanoes**: Major eruptions tend to cool the climate briefly by injecting aerosols into the stratosphere; they do not explain a long-term warming trend.
   - **Internal variability** (e.g., El Niño/La Niña, decadal oscillations) causes short‑term ups and downs but not the clear multi‑decadal upward trend seen globally.

4. **Models and observations match when human factors are included**
   - Climate models run with **only natural factors** (sun + volcanoes) **fail to reproduce** the observed warming since about 1950.
   - The same models **match the observed warming well** when human greenhouse gases and aerosols are included.

5. **Attribution numbers (approximate)**
   - Best estimates attribute ~1.1–1.3°C of global warming since 1900 to human activities.
   - Natural factors over the same period contribute close to zero net change (small ups and downs but no sustained trend).

If you’d like, I can walk through any part of the evidence in more detail (e.g., the CO₂ fingerprint, how attribution studies work, or the role of different human activities).


text:
Yes. The evidence is overwhelming that human activities—primarily the burning of fossil fuels, plus deforestation and certain industrial processes—are the main cause of the rapid warming observed since about 1950.

Key points:

1. **Greenhouse gases match the warming pattern**
   - CO₂, methane, and nitrous oxide have all increased sharply since the Industrial Revolution, mainly from:
     - Burning coal, oil, and gas (power, transport, industry)
     - Deforestation and land-use change
     - Agriculture and industrial chemicals
   - The physics of how these gases trap heat has been understood for over a century and is confirmed by lab experiments, satellite measurements, and energy-balance calculations.

2. **Natural factors can’t explain the observed changes**
   - **Solar output**: Has shown no long-term increase since mid‑20th century; if anything, a slight downward trend in recent decades. If the Sun were driving warming, we’d see warming throughout the atmosphere, but:
   - **Observed pattern**: The lower atmosphere (troposphere) is warming while the upper atmosphere (stratosphere) is cooling—this is the fingerprint of greenhouse-gas–driven warming, not solar change.
   - **Volcanoes**: Large eruptions tend to cool the climate temporarily by reflecting sunlight; they cannot explain sustained multi-decade warming.
   - **Internal variability** (e.g., El Niño/La Niña) causes year-to-year ups and downs but not the long-term upward trend.

3. **Attribution studies quantify the human role**
   - The IPCC (Intergovernmental Panel on Climate Change) reports that:
     - It is *unequivocal* that human influence has warmed the atmosphere, ocean, and land.
     - Best estimates: More than 100% of the net warming since 1950 is due to human causes, because:
       - Greenhouse gases cause strong warming.
       - Some human-emitted aerosols (air pollution) cause cooling that partially offsets that warming.
       - Natural factors alone would have led to roughly flat or slightly cooling temperatures over that period.
   - Without human emissions, climate models do not reproduce the observed late‑20th and early‑21st‑century warming. Include human emissions, and they match well.

4. **Multiple independent lines of evidence point the same way**
   - Rising CO₂ measured directly (e.g., Mauna Loa record since 1958).
   - Isotopic “fingerprint” of carbon in the air shows it comes mainly from fossil fuels.
   - Oceans absorbing over 90% of the excess heat, consistent with greenhouse forcing.
   - Melting glaciers and ice sheets, shrinking Arctic sea ice, rising sea levels, and shifting ecosystems all track the warming trend.

Consensus:
- Virtually all major scientific bodies (e.g., IPCC, US National Academy of Sciences, UK Royal Society, WMO) agree that humans are the dominant cause of recent global warming.
- Surveys of climate experts consistently find very high agreement (on the order of 90–100%) that human activities are the primary driver of the post‑1950 warming.

So: yes, recent climate change is driven mainly by human activity, with natural factors playing only a minor role in the overall warming trend.


text:
Yes. Multiple independent lines of evidence show that human activity is the dominant cause of the rapid warming observed since the mid‑20th century.

Key points:

1. **Scientific consensus**
   - The IPCC (2021) states it is *“unequivocal”* that human influence has warmed the atmosphere, ocean, and land.
   - Attribution studies estimate that humans are responsible for **>100% of the net warming** since 1850–1900, because natural factors alone would likely have caused slight cooling or very small warming over this period.

2. **Greenhouse gases and their sources**
   - CO₂, methane, and nitrous oxide concentrations are now higher than at any time in at least 800,000 years.
   - Isotopic signatures and emissions inventories show that the extra CO₂ comes mainly from **fossil fuel combustion**, cement production, and deforestation.
   - Human activities have increased CO₂ from ~280 ppm (pre‑industrial) to over 420 ppm today.

3. **Ruling out natural drivers**
   - **Solar output**: Satellite measurements since the late 1970s show no long‑term increase matching the strong warming trend.
   - **Volcanoes**: Large eruptions generally cool the climate temporarily by injecting reflective aerosols; recent volcanic activity cannot explain sustained warming.
   - **Orbital cycles** (Milankovitch): Act on tens of thousands of years, not decades, and currently would favor slight cooling, not warming.
   - Internal variability (e.g., El Niño/La Niña) explains year‑to‑year fluctuations but not the persistent long‑term warming trend.

4. **Climate models and observations**
   - When models include **only natural factors**, they cannot reproduce the rapid warming since ~1950.
   - When they include **human greenhouse gas emissions and aerosols**, they match the observed temperature rise, spatial patterns, and many other changes (ocean heat content, Arctic sea ice decline, etc.).

5. **Attribution of responsibility**
   - IPCC AR6 best estimate: human activities have caused about **1.07°C** of warming (±0.2°C) from 1850–1900 to 2010–2019.
   - Net effect of natural factors over that period is close to zero (slightly cooling or slightly warming, depending on method), so **human forcing dominates**.

If you’d like, I can go into more detail on the evidence (e.g., fingerprint studies, isotopes, or specific IPCC figures) or on what “>100% of the warming” means in practice.


text:
Yes. The scientific evidence is overwhelming that human activity is the primary driver of the rapid climate change observed since the mid‑20th century.

Key points:

1. **Scientific consensus**
   - The IPCC (Intergovernmental Panel on Climate Change) states it is *“unequivocal”* that human influence has warmed the atmosphere, ocean, and land.
   - Multiple studies show that over 90–97% of actively publishing climate scientists agree that recent warming is mainly human‑caused.

2. **What’s driving the change**
   The main human influences are:
   - **Burning fossil fuels** (coal, oil, gas) → CO₂ and other greenhouse gases
   - **Deforestation** → less CO₂ absorbed by forests
   - **Agriculture and industry** → methane, nitrous oxide, industrial gases
   - These gases trap more heat, enhancing the natural greenhouse effect.

3. **How we know it’s us, not natural cycles**
   - **Pattern of warming**: Lower atmosphere (troposphere) warms while the upper atmosphere (stratosphere) cools—this matches greenhouse gas theory, not solar changes.
   - **Solar output**: Has shown no long‑term increase since the 1970s, while temperatures have risen sharply.
   - **Volcanoes and natural variability**: Their effects are too small and/or short‑lived to explain the long‑term warming trend.
   - **Attribution studies**: Climate models that include only natural factors cannot reproduce the observed warming; models that include human emissions match the data well.

4. **Magnitude of human influence**
   - Since about 1850, humans have increased atmospheric CO₂ from ~280 ppm to over 420 ppm.
   - The IPCC concludes that human activities are responsible for **essentially all** of the net global warming observed since 1850–1900 (about 1.1°C so far).

If you’d like, I can go into more detail on any of these lines of evidence (e.g., models vs observations, role of oceans, or specific gases).


text:
Yes. The overwhelming evidence shows that human activity is the primary driver of the rapid climate change observed since the mid‑20th century.

Key points:

1. **Greenhouse gas increase is human‑caused**
   - CO₂ has risen ~50% since preindustrial times (from ~280 ppm to over 420 ppm).
   - This rise matches known human emissions from:
     - Burning coal, oil, and gas
     - Deforestation and land-use change
     - Industrial processes (cement, some chemicals)
   - The carbon isotopic “fingerprint” (ratio of carbon‑12 to carbon‑13) clearly points to fossil fuels and vegetation, not volcanoes or oceans, as the dominant source.

2. **Physical theory was established long before current warming**
   - The heat‑trapping effect of CO₂ and other greenhouse gases is basic physics, quantified since the 19th century (Fourier, Tyndall, Arrhenius).
   - Adding greenhouse gases reduces heat loss to space; satellites directly measure this reduction at the wavelengths of CO₂, methane, etc.

3. **Climate models and observations align**
   - When models include only natural factors (solar variability, volcanoes), they cannot reproduce the strong warming trend of the last ~50–70 years.
   - When human greenhouse gases and aerosols are included, models match the observed global temperature rise and spatial patterns of warming.

4. **Observed “fingerprints” match human forcing**
   Scientists don’t just look at temperature; they look at patterns:
   - Troposphere (lower atmosphere) warming while the stratosphere cools → expected from greenhouse gases, not from increased solar output.
   - Nights warming more than days, winters warming more than summers → consistent with greenhouse-gas–driven warming.
   - Greater warming over land than oceans, and amplified warming in the Arctic → again, consistent with human-caused forcing and feedbacks.

5. **Natural drivers can’t explain recent trends**
   - **Solar output** has shown no long-term upward trend since the late 1970s (satellite era), yet temperatures have risen strongly.
   - **Volcanoes** mostly cause temporary cooling by injecting reflective aerosols into the stratosphere.
   - Internal variability (like El Niño/La Niña) causes year-to-year or decade-scale ups and downs, but not a persistent multi‑decade warming trend of this magnitude.

6. **Attribution statements from major scientific bodies**
   - IPCC (2021): “It is unequivocal that human influence has warmed the atmosphere, ocean and land.”
   - The best estimate is that **essentially all** of the observed warming since 1950 is due to human activities; natural factors alone would likely have caused slight cooling or minimal change over that period.

In sum: recent climate change is not just “part of a natural cycle.” Natural factors always play a role, but the dominant cause of the strong, rapid warming over the last several decades is human emissions of greenhouse gases and related activities.


text:
Yes. The evidence is overwhelming that human activity is the primary driver of the rapid warming observed since the mid-20th century.

Key points:

1. **Attribution studies**
   - The IPCC (AR6, 2021) concludes it is *“unequivocal that human influence has warmed the atmosphere, ocean and land.”*
   - Best estimates: **>100% of the net warming since 1950** is due to human activities, because natural factors alone (solar changes, volcanoes) would have caused a slight cooling or near-zero change over this period.

2. **Main human drivers**
   - **Greenhouse gas emissions** from fossil fuel burning (coal, oil, gas), deforestation, and agriculture:
     - CO₂: from energy, industry, land-use change.
     - Methane (CH₄): livestock, rice, fossil fuel extraction, waste.
     - Nitrous oxide (N₂O): fertilizers, industry.
   - These gases trap outgoing infrared radiation, enhancing the greenhouse effect. The physics has been understood since the 19th century and is directly measured by satellites and surface instruments.

3. **Why natural causes don’t explain recent warming**
   - **Solar output**: has shown no long-term upward trend since about 1950; if anything, a slight decline in recent decades.
   - **Volcanoes**: big eruptions cause short-term cooling, not long-term warming.
   - **Orbital cycles** (Milankovitch): operate over tens of thousands of years and currently would favor a very gradual cooling, not rapid warming.
   - Climate models and observations show that without humanforcing you cannot reproduce the magnitude, pattern, and timing of the observed warming.

4. **Multiple independent lines of evidence**
   - The pattern of warming (troposphere warming, stratosphere cooling) matches that expected from greenhouse gases, not from the Sun.
   - The oceans, which absorb >90% of excess heat, are warming from the surface down.
   - Nighttime temperatures are rising faster than daytime, and winters faster than summers—consistent with enhanced greenhouse effect.
   - Carbon isotopes and oxygen concentration trends in the air show that the extra CO₂ is from fossil fuels.

5. **Scientific consensus**
   - Studies of the literature consistently find **over 95–99%** agreement among climate scientists that humans are the dominant cause of recent global warming.
   - All major national academies of science and professional climate/science organizations worldwide endorse this conclusion.

If you’d like, I can go into more detail about a specific line of evidence (e.g., how we know it’s not the Sun, or how attribution modeling works).


text:
Yes. Multiple independent lines of evidence show that human activities—primarily the burning of fossil fuels and deforestation—are the dominant cause of the rapid warming observed since about 1950.

Key points:

1. **Scientific consensus**
   - IPCC (2021): It is *“unequivocal that human influence has warmed the atmosphere, ocean and land.”*
   - Attribution studies find that **>100% of the net warming** since 1950 is due to human activities; natural factors alone would likely have caused slight cooling over that period.

2. **Greenhouse gas increases**
   - CO₂ has risen from ~280 ppm (pre‑industrial) to over 420 ppm today—a level not seen for at least 2–3 million years.
   - The isotopic “fingerprint” of carbon in the atmosphere matches fossil fuel sources, not volcanoes or other natural sources.

3. **Physical fingerprint of warming**
   Observed patterns match what models predict from greenhouse gas forcing, not from solar or natural variability:
   - Troposphere (lower atmosphere) warming while the **stratosphere cools**.
   - **More warming at night** than daytime.
   - **Stronger warming over land** than over oceans.
   - **Arctic amplification** (faster warming at high northern latitudes).

4. **Role of natural factors**
   - **Solar output** has shown no long-term upward trend since the late 1970s, while temperatures have risen sharply.
   - **Volcanoes** mostly cool the climate on short timescales by blocking sunlight.
   - **Internal variability** (El Niño/La Niña, etc.) causes year‑to‑year fluctuations but cannot explain the long-term trend.

5. **Quantitative attribution**
   - Human greenhouse gases: strong warming effect.
   - Human aerosols (pollution particles): partially offset that warming (cooling effect).
   - Net result: humans are responsible for essentially **all of the observed net warming** since mid‑20th century.

If you’d like, I can go deeper into one aspect (e.g., how attribution studies work, or why solar changes can’t explain the trend).


text:
Yes. The best available evidence shows that human activity is the primary driver of the rapid climate change observed since the mid‑20th century.

Key points:

1. **Scientific consensus**
   - The IPCC (Intergovernmental Panel on Climate Change) states it is *“unequivocal”* that human influence has warmed the atmosphere, ocean, and land.
   - Multiple national science academies (U.S., UK, EU, etc.) independently agree: recent warming is mainly due to human activities.

2. **Main cause: greenhouse gas emissions**
   - Burning fossil fuels (coal, oil, gas) for electricity, heat, transport, and industry releases CO₂ and other greenhouse gases.
   - Deforestation, agriculture, and some industrial processes add CO₂, methane (CH₄), and nitrous oxide (N₂O).
   - Atmospheric CO₂ has risen from ~280 ppm (pre‑industrial) to over 420 ppm today—levels not seen in at least 2–3 million years.

3. **Attribution studies**
   - Climate models and statistical analyses compare:
     - Simulations with human and natural factors (greenhouse gases, aerosols, volcanoes, solar changes).
     - Simulations with natural factors only.
   - Only the simulations **including human emissions** reproduce:
     - The magnitude and pattern of global warming.
     - Warming of the lower atmosphere and cooling of the upper atmosphere.
     - Greater warming over land than ocean and in the Arctic.
   - Natural factors alone (solar variation, volcanoes) cannot explain the observed trend since ~1950.

4. **Human share of recent warming**
   - The IPCC estimates that human activities are responsible for **about 100% of the net global warming** since 1850–1900, because:
     - Greenhouse gases cause more warming than what we see.
     - Some human-made aerosols cool the climate and partially offset that warming.
   - Net effect: humans are responsible for essentially all of the observed warming over recent decades; natural factors have contributed little and sometimes slightly cooled.

5. **Observed changes consistent with human forcing**
   - Rising global average temperatures (~1.1–1.3°C above pre‑industrial).
   - More frequent and intense heatwaves.
   - Melting glaciers and ice sheets, shrinking Arctic sea ice.
   - Rising sea levels from thermal expansion and ice melt.
   - Shifts in rainfall patterns and extremes.

If you’d like, I can go into more detail on any aspect—how attribution studies work, the role of natural cycles (like El Niño), or how strong the consensus really is.


text:
Yes. Multiple independent lines of evidence show that human activity is the primary driver of the rapid climate change observed since the mid‑20th century.

Key points:

1. **Greenhouse gas increases are clearly human-caused**
   - CO₂ concentrations have risen from ~280 ppm (pre‑industrial) to over 420 ppm today.
   - The rate and pattern of increase match human emissions from burning fossil fuels, deforestation, and cement production.
   - The chemical “fingerprint” of the extra CO₂ in the atmosphere (carbon isotope ratios and declining atmospheric oxygen) points directly to fossil fuels.

2. **The warming matches what physics predicts from those gases**
   - Basic physics (known for over a century) shows that more CO₂, methane, and nitrous oxide trap more heat.
   - Climate models that include human greenhouse gas emissions reproduce the observed warming trend and many details (e.g., more warming over land than oceans, more in the Arctic, nighttime warming > daytime).
   - Models that include only natural factors (solar changes, volcanoes) cannot reproduce the observed warming since about 1950.

3. **Natural drivers don’t explain recent trends**
   - **Solar output** has shown no long-term increase since the late 1970s; if anything, a slight downward trend, while temperatures kept rising.
   - **Volcanic activity** overall has had a slight cooling influence by adding reflective particles to the atmosphere.
   - **Internal variability** (El Niño/La Niña, decadal oscillations) causes short-term ups and downs but not the long-term upward trend.

4. **Attribution studies quantify the human role**
   - The IPCC (the global scientific assessment body) concludes it is *“unequivocal”* that human influence has warmed the atmosphere, ocean, and land.
   - Best estimates attribute **>100%** of the net warming since 1950 to human activities: greenhouse gas warming offset partly by human-made aerosols that cool. Natural factors alone would likely have led to slight cooling or near-flat temperatures.

5. **Observed “fingerprints” match human forcing**
   - Troposphere (lower atmosphere) warming while stratosphere cools: expected from greenhouse gases, not from increased solar output.
   - More heat stored in the oceans, retreating glaciers and ice sheets, earlier spring, shifting species ranges—all consistent with greenhouse-driven warming.

In summary: recent climate change is not just influenced by humans; the best evidence indicates human activities are the dominant cause of the warming observed over the past ~70 years.


text:
Yes. The overwhelming evidence shows that human activity is the primary driver of the rapid climate change observed since the mid‑20th century.

Key points:

1. **Greenhouse gas increases match human emissions**
   - CO₂ in the atmosphere has risen ~50% since pre‑industrial times (from ~280 ppm to over 420 ppm).
   - The amount and isotopic “fingerprint” of CO₂ match what we’d expect from burning fossil fuels and deforestation, not from natural sources like volcanoes.

2. **Natural factors can’t explain recent warming**
   - **Solar output**: measured changes in the Sun’s energy are too small and, if anything, slightly cooling over the last few decades.
   - **Volcanoes**: major eruptions tend to cool the climate temporarily by blocking sunlight.
   - **Internal variability** (e.g., El Niño/La Niña) causes year‑to‑year ups and downs, but not the long‑term warming trend.

3. **Climate models only match observations when human factors are included**
   - When models include only natural drivers (Sun, volcanoes), they do *not* reproduce the strong warming since ~1950.
   - When human greenhouse gases and aerosols are added, the models match the observed warming pattern and magnitude.

4. **Scientific consensus**
   - The IPCC (Intergovernmental Panel on Climate Change) states it is “unequivocal” that human influence has warmed the atmosphere, ocean, and land.
   - Multiple studies find that 90–100% of the observed warming since 1950 is due to human activities, mainly:
     - Burning coal, oil, and gas
     - Deforestation and land‑use change
     - Some industrial and agricultural processes (e.g., methane, nitrous oxide)

5. **Characteristic “fingerprints” of human‑caused warming**
   - Troposphere (lower atmosphere) warming while the stratosphere cools.
   - Nights warming faster than days.
   - Polar regions (especially the Arctic) warming faster than the global average.
   - Ocean heat content rising steadily.

In sum: natural factors still influence climate, but the *dominant* cause of the rapid, global-scale warming over the last ~70 years is human activity, especially greenhouse gas emissions.


text:
Yes. The evidence is overwhelming that human activity is the primary driver of the rapid climate change observed since the mid‑20th century.

Key points:

1. **Greenhouse gas increases match human emissions**
   - CO₂ in the atmosphere has risen from ~280 ppm (pre‑industrial) to over 420 ppm today.
   - The amount and isotopic “fingerprint” of CO₂ (more from fossil fuels, less from natural sources) match what we know from burning coal, oil, and gas, plus deforestation.

2. **Natural factors can’t explain the warming**
   - **Solar output**: Satellite measurements since the 1970s show no long‑term increase in solar energy that could explain the warming trend.
   - **Volcanoes**: Large eruptions tend to cool the climate temporarily by blocking sunlight.
   - **Internal variability** (like El Niño/La Niña) causes year‑to‑year ups and downs, but not the persistent multi‑decade warming trend.

3. **Climate models only reproduce recent warming when human factors are included**
   - When models include only natural drivers (sun, volcanoes), they do *not* show the strong warming observed since about 1950.
   - When human greenhouse gas emissions and aerosols are added, the models match the observed pattern and magnitude of warming.

4. **The pattern of warming matches greenhouse gas physics**
   - The lower atmosphere (troposphere) is warming while the upper atmosphere (stratosphere) is cooling—exactly what is expected from increased greenhouse gases, not from more solar energy (which would warm both).
   - Nights and winters are warming faster than days and summers, and the Arctic is warming faster than the global average—again, consistent with greenhouse‑driven warming.

5. **Scientific consensus**
   - The IPCC (Intergovernmental Panel on Climate Change) states it is “unequivocal” that human influence has warmed the atmosphere, ocean, and land.
   - Multiple studies find that over 90–97% of actively publishing climate scientists agree that recent warming is primarily human‑caused.

In summary: natural factors contribute to short‑term variability, but the dominant cause of the rapid, sustained global warming over the past ~70 years is human emissions of greenhouse gases, mainly from burning fossil fuels and land‑use changes.


text:
Yes. Multiple independent lines of evidence show that human activity is the dominant cause of the rapid warming observed since the mid‑20th century.

Key points:

1. **Scientific consensus**
   - The IPCC (2023) states it is *“unequivocal”* that human influence has warmed the atmosphere, ocean, and land.
   - National academies of science worldwide (US, UK, EU, etc.) agree that recent climate change is primarily human‑driven.

2. **Greenhouse gas increases match human emissions**
   - CO₂ has risen from ~280 ppm (pre‑industrial) to over 420 ppm today.
   - The amount and isotopic “fingerprint” of CO₂ in the air match what we expect from burning fossil fuels and deforestation.
   - Other human‑made gases (methane, nitrous oxide, industrial gases) have also increased sharply.

3. **Natural factors can’t explain recent warming**
   - **Solar output**: measured changes in solar energy over recent decades are too small and in the wrong direction to explain the observed warming.
   - **Volcanoes**: major eruptions tend to cool the climate temporarily by injecting aerosols that reflect sunlight.
   - **Internal variability** (e.g., El Niño/La Niña) causes year‑to‑year fluctuations but not the long‑term warming trend.

4. **Climate models with and without human influence**
   - When models include only natural factors (sun + volcanoes), they do *not* reproduce the strong warming since ~1950.
   - When human greenhouse gas and aerosol emissions are included, models match the observed temperature rise and many other patterns (e.g., more warming over land than ocean, Arctic amplification, warming lower atmosphere and cooling upper atmosphere).

5. **Attribution studies**
   - Formal attribution research estimates that humans are responsible for essentially *all* of the net warming since 1950.
   - Natural factors alone would likely have produced slight cooling or near‑flat temperatures over that period.

If you’d like, I can go into more detail on any of these: the evidence from temperature records, how attribution studies work, or what role specific activities (like fossil fuels vs. deforestation) play.


text:
Yes. The evidence is overwhelming that human activity is the primary driver of the rapid climate change observed since the mid‑20th century.

Key points:

1. **Greenhouse gas increases match human emissions**
   - CO₂ in the atmosphere has risen from ~280 ppm (pre‑industrial) to over 420 ppm today.
   - The amount and isotopic “fingerprint” of CO₂ (more from fossil fuels, less from natural sources) match what we know from fossil fuel burning, deforestation, and cement production.
   - Other human-made greenhouse gases (methane, nitrous oxide, many industrial gases) have also increased sharply.

2. **Natural factors can’t explain the observed warming**
   - **Solar output**: Satellite measurements since the 1970s show no long‑term increase in solar energy that could explain the warming trend.
   - **Volcanoes**: Major eruptions tend to cool the climate temporarily by injecting particles that reflect sunlight.
   - **Orbital cycles**: These operate over tens of thousands of years and are too slow and too weak to explain the rapid warming of the last ~70 years.
   - Climate models that include only natural factors fail to reproduce the observed warming; models that include human emissions match it well.

3. **Physical understanding of the greenhouse effect**
   - The basic physics (CO₂, CH₄, etc. trapping infrared radiation) has been understood for over a century.
   - Laboratory measurements, satellite observations, and surface data all confirm that increased greenhouse gases are trapping more heat.

4. **Observed patterns match human-caused warming**
   - The lower atmosphere (troposphere) is warming while the upper atmosphere (stratosphere) is cooling—exactly what is expected from greenhouse gas increases, not from more solar energy.
   - Nights are warming faster than days, and winters faster than summers—again consistent with greenhouse forcing.
   - Oceans are absorbing over 90% of the excess heat, and ocean heat content is rising steadily.

5. **Scientific consensus**
   - Major scientific bodies (IPCC, U.S. National Academy of Sciences, Royal Society, WMO, etc.) conclude that it is *extremely likely* (IPCC: >95% probability) that more than half of the observed warming since 1950 is due to human activities, with best estimates attributing **most** of it to humans.
   - Recent attribution studies typically find that essentially **all** of the long‑term warming trend since ~1970 is due to human influence, with natural factors contributing little or even a slight cooling.

In summary: natural variability and natural forcings still exist and affect year‑to‑year and decade‑to‑decade fluctuations, but the **dominant cause of the long‑term warming trend since the mid‑20th century is human emissions of greenhouse gases and related activities.**
