Climate Change And Mexico
Unknown The Effect of Increased Greenhouse Gasses on Mexico and it's Effort to Reduce Environmental Damage Introduction For over a hundred years, scientists have been carefully gathering and verifying data on the earth's temperature. The latest data reveals some striking trends: - All 10 of the warmest years on record have occurred in the last 15 years - The 1990's have already been warmer than the 1980's- the warmest decade on record - The global average surface temperature has risen 0.5 degrees (site source) For the first time ever, the Intergovernmental Panel on Climate Change, the authoritative international body charged with studying this issue, concluded that the observed increase in global average temperature over the last century "is unlikely to be entirely natural in origin" and that "the balance of evidence suggests that there is a discernible human influence on global climate." The Earth's climate is the result of extremely complex interactions among the atmosphere, the oceans, the land masses, and living organisms, which are all warmed daily by the sun's enormous energy. This heat would radiate back into space if not for the atmosphere, which relies on a delicate balance of heat-trapping gases, including water vapor, carbon dioxide, nitrous oxide, and methane, to act as a natural "greenhouse," keeping in just the right amount of the sun's energy to support life. For the past 150 years, though, the atmospheric concentrations of ...
