Clouds Do Not Cause Climate Change

Despite recent scientific speculation to the contrary, clouds do not cause climate change, says Texas A&M atmospheric sciences professor Andrew Dessler. Rather, they act almost singularly as a feedback mechanism.

Limited Nuclear War Could Halt Global Warming, Short Term, NASA Predicts

The scientists used a general circulation model known as ModelE (developed at NASA’s Goddard Institute for Space Studies, New York). The model calculates ocean-atmosphere coupling effects in addition to allowing varying aerosol inputs.

The initial input for the simulation was 5 teragrams (megatons) of black carbon particles injected into Earth’s upper troposphere. This is the estimated result of the surface detonation of 100 Hiroshima-size bombs (each equivalent to 15K tons of TNT).
