Analysis: Why scientists think 100% of global warming is due to humans | Carbon Brief

The science on the human contribution to modern warming is quite clear. Humans emissions and activities have caused around 100% of the warming observed.

> It is extremely likely that human activities caused more than half of the observed increase in global average surface temperature from 1951 to 2010.

> We know human activities are driving the increase in CO2 concentrations because atmospheric CO2 contains information about its source.

Are Humans the Major Cause of Global Warming?

A straightforward explanation of how we know that humans cause global warming, using charts, graphs, and plain language.

> Tens of thousands of scientists in more than a hundred nations have amassed an overwhelming amount of evidence pointing to a clear conclusion: Humans are the main cause.

How are humans responsible for global warming?

Deforestation and burning fossil fuels are chief culprits

Twenty-first century sea-level rise could exceed IPCC projections for strong-warming futures

While twentieth century sea-level rise was dominated by thermal expansion of ocean water, mass loss from glaciers and ice sheets is now a larger annua…

Study Confirms Climate Models are Getting Future Warming Projections Right

A new evaluation of global climate models used to project Earth's future global average surface temperature finds that most have been quite accurate.
