Document Summary
Greenhouse gases & climate change: earth has seen many changes in climate, accompanied by drastic shifts in biota, entered 5th major ice age about 2. 58 mya, since then, cycling between more and less ice. An ice age has alternating glacial and interglacial periods. Four pioneers of climate prediction: exit the current interglacial in 10 to. 50 thousand yr: glaciers return, sea level drops, canada is toast, but the short-term prediction is very different, due to human activity, crowley. Arrhenius calculated overall effects of co2 as a greenhouse gas. Richardson used the equations to calculate the first numerical weather prediction. Perhaps some day in the dim future it will be possible to advance the computations faster than the weather advances but that is a dream. Bjerknes wrote the primitive equations for a model of weather including air movements, temperature, and water content. Intergovernmental panel on climate change: different groups working in various countries on:
