Document Summary

Dam construction- can"t come back to lay eggs. Physical environment- determines where organisms can live & what resources are available. Weather: current conditions- temp. , precipitation, humidity, cloud cover (hot this week compared to same week last year is because of weather) Climate: long term description of weather, based on averages, measured over decades (hot this time of the year- expected because of climate) Long term climate change - changes in intensity & distribution of sun"s radiation. Current climate changes - because of increased co2 etc in atmosphere due to humans. Sun = ultimate source of energy drives global climate system. Energy gains from sun = energy losses then earth"s temp remains stable. Solar radiation coming in = 50% absorbed by surface + 20% absorbed by atmos. Greenhouse gases- bounce back ir radiation (e. g. h2o, co2, ch4, n2o) Without them = 33o cooler therefore need them. Equator: same e. spread over small area & less atmos. to go through.
