Document Summary

Poor suffer the most, but contribute the least. 64% produced by high income countries, suffer only 20% 36% produced by low income countries, suffer 80% China produces the most (24%), us produces most co2 emissions. Projected that co2 emissions from fossil fuels would raise surface temperature. Ways to measure: tree rings, living things in sediments, ice cores from antarctica. Every ~5 years there is an international panel on climate change. 1995: there is a discernible human influence on the global climate. 2001: most of the warming observed over the last 50 years is attributable to human activities. 2007: warming is unequivocal, more than 90% certain that humans have increased greenhouse gases. More than 25,000 physical and biological systems have changed throughout the world. More extreme weather: floods, droughts, hurricanes, wildfires. Falling crop yields, especially in developing countries. Glaciers disappear, water supply decreases, sea level rise threaten cities. Damage to coral reefs, species face extinction.
