Mar 25, 2021 · A NASA supercomputer model shows how greenhouse gases like carbon dioxide (CO 2) – a key driver of global warming – fluctuate in Earth’s atmosphere throughout the year.

Jan 31, 2012 · A new NASA study underscores the fact that greenhouse gases generated by human activity—not changes in solar activity—are the primary force driving global warming.

In 1856, Eunice Foote discovered that carbon dioxide (CO₂) and water vapor in Earth's atmosphere trap escaping infrared (heat) radiation, acting like a blanket to keep the surface …

As a direct effect, aerosols scatter sunlight back into space. As an indirect effect, they can either help or hinder the development of clouds, which in turn can either cool or warm the planet.
