AI Overview
We know humans are causing climate change primarily because of the dramatic increase in atmospheric carbon dioxide levels, which directly correlates with the burning of fossil fuels, and the unique chemical signature of this added carbon dioxide points to its human origin; alongside this, we observe warming trends in the planet's temperature, melting ice caps, and rising sea levels, all consistent with the effects of increased greenhouse gases in the atmosphere.
Key points supporting human-caused climate change:

Key points supporting human-caused climate change:
- Rising CO2 levels:
Precise measurements show a significant increase in atmospheric carbon dioxide since the industrial revolution, with the majority of this increase attributed to fossil fuel burning. - Carbon isotope analysis:
The specific ratio of carbon isotopes in the added CO2 matches the signature of fossil fuels, providing strong evidence that the source is human activity. - Climate models:
Computer models accurately predict observed warming trends when factoring in human-caused greenhouse gas emissions. - Observed impacts:
Melting glaciers, rising sea levels, extreme weather events, and changes in plant and animal life are consistent with the warming predicted by climate models.
