Document Summary
Climate change is not caused by co2: didn"t initiate warming in the past but it did amplify it, natural cycle adds and removes co2 in balance, but humans add co2 without removing any. It hasn"t warmed since 1998: lag in the system. Climate change ain"t bad: risk of decrease in agri yield, water threatened, health impacts, climate change refugees, health impacts. Cheaper to adapt than mitigate: adaptation without mitigation results in suffering, without mitigation, long term costs will be much, much higher. Climate (long term description of atmospheric conditions in a certain location) vs weather (short term description of atmospheric conditions in a certain location) Radiative forcing a change in balance between absorbed solar radiation and emitted radiation. Orbital forcing change in earth"s orbit and axis alters solar radiation received by earth. Water vapor snow and ice cover (ex. Less snow, reduced albedo, more radiation absorbed, further warming) Rising sea covering more surface, decreasing total albedo) vegetation clouds (ex.
