ALONG WITH SOCIETAL IMPACTS FROM:EARTHQUAKES,VOLCANIC ERUPTIONS, AND TSUNAMIS; HURRICANES, TYPHOONS AND TORNADOES; LANDSLIDES, DROUGHTS AND WILDFIRES; HEAT WAVES, AND GLOBAL WARMING FRAGILE PLANET EARTH HEAT AND WARM AIR: A PRESCRIPTION FOR DISASTER
Thousands killed and injured. Hundreds of thousands of homes inundated or destroyed. Infrastructure damaged and destroyed. Toxic materials released into the air, water, and soil. Health care needs sharply increased everywhere. Millions evacuated and hundreds of thousands displaced. Livelihoods of hundreds of millions adversely affected. $ Tens of billions in insured and uninsured economic losses.. SOCIETAL IMPACTS DURING 2007
We must consider the possible impact of global climate change on the global distribution of floods, landslides, droughts, and wildfires. Hurricanes and typhoons are seasonal, Earthquakes, tsunamis, and volcanoes have tectonic origins. Warmer air and warmer water are a Rx for tornadoes, hurricanes, and typhoons. Warmer air can hold more water and will unleash more energy, making wind fields and storms stronger, surges higher, and rainfall heavier. This mechanism may explain an observed increase during 2007 in flash floods and riverine floods in Europe and Asia.. GLOBAL CLIMATE CHANGE
