Most come from the combustion of fossil fuels in cars, buildings, factories, and power plants. The gas responsible for the most warming is carbon dioxide, or CO2.

What percentage of CO2 is man made?

I am often asked how carbon dioxide can have an important effect on global climate when its concentration is so small – just 0.041 percent of Earth’s atmosphere. And human activities are responsible for just 32 percent of that amount. I study the importance of atmospheric gases for air pollution and climate change.
