Document Summary
Sun rays 51 units + re-radiated heat 9. 6 units. Everything on earth (plants animals) evolve in cold house. 1 relatively warmer period medieval warm period (900-1300 ad) 1 relatively cold period= little ice age (1645 - 1715) Natural process from plants & fossil fuel burning & other human associated activities. In the atmosphere is correlated/mean average global temp. Plants, animals, humans all evolved in ice house 65mya. Global climate is spatially heterogeneous = not equal everywhere in the world. Temp will not be uniformly distributed across the global. Ca- 6 year drought while se asia- monsoon while new england- snow. Our climate in comparison with our climate/earth s past. Combination of precipitation (rainfall) and temp patterns unlike any current climate. We cannot preicte furture climate changes - animal life. Graph 3 closer to equator to get warmer closer to artic for cold. Some species are already near their physcilogical limit. Artic: polar bear = top of mountain.
