Carbon Dioxide andd Climate Change: The Mechanism of Warming

When CO English concentrations s rise, thee enhanced greenhouses effect traps more heet. Thies exactforward physional principle is backed by decades of satellite measurements, surface temperatur records, and climate models. But the impacts go far beyond simple warming - they cascade thugh every part of the climate system.
