Document Summary
Impacts of climate change & what to do. Particular trace gases in the atmosphere (h2o, co2, ch4, n2o, cfcs) trap infrared radiation and exert a greenhouse effect . Patterns and amounts of precipitation likely to change. Ice and snow cover, permafrost, in decine. Based on ghg increase & temperature change on a global scale. Do nothing and emissions continue to accelerate vs. Immediate cap and rapid reduction of global emissions. Will not be evenly distributed across the earth. Higher latitudes, altitudes will warm more rapidly. In the future: more extreme storm events. Why - tropical cyclones occur over oceans and their intensity and severity is directly influenced by the temperature of the surrounding surface temperature. Half a degree higher for ocean temp - global scale since 2000. In the future: more severe droughts over continental areas. Why - seasonal precipitation shortfalls linked to sea surface temperatures. Drought in sudano-sahelian africa - places based on agriculture in.
