Fact check: Is climate chamge happans because of the people

1. Summary of the results

The scientific consensus overwhelmingly confirms that climate change is happening and is primarily caused by human activities. Specifically:

• 97% of climate scientists agree that warming trends are extremely likely due to human activities ^[1]
• Earth's average surface temperature has risen by approximately 1.8°F (1.0°C) since 1880 ^[2]
• Carbon dioxide levels have increased dramatically from 280 to 410 parts per million, reaching levels not seen in 3 million years ^{[2] [3]}
• The certainty of human-caused climate change is comparable to the scientific certainty of the link between smoking and cancer ^[4]

2. Missing context/alternative viewpoints

Several important contextual points were missing from the original query:

• While Earth's climate has naturally changed throughout history, the current rate of warming is unprecedented and doesn't align with natural cycles ^[5]
• Multiple lines of evidence support human causation, including:
• The chemical signature of carbon dioxide ^[6]
• Computer models showing that little to no warming would have occurred without human factors ^[7]
• The timing of temperature increases matching human industrial activity ^[6]
• Each of the last four decades has been progressively warmer than the previous ones ^[7]

3. Potential misinformation/bias in the original statement

The original statement's grammatical errors and oversimplification could lead to misunderstanding of:

• The complexity of climate science: It's not just "people" in general, but specific human activities that are causing climate change, primarily:
• Burning of fossil fuels ^{[2] [5]}
• Deforestation ^{[4] [6]}
• The scale of scientific agreement: This isn't a debated topic among scientists - tens of thousands of scientists across over 100 nations have reached this conclusion ^[4]
• The historical context: The changes observed are not part of natural variation but represent an unprecedented rate of change in Earth's climate system ^[5]

It's worth noting that various industries, particularly fossil fuel companies, have financial interests in downplaying human responsibility for climate change, while environmental organizations and renewable energy companies benefit from emphasizing human causation.
