Inevitably, our world and civilisation will some day come to an end. Here we suggest a few of the many possible EOTWAWKI (End Of The World As We Know It) scenarios, and provide a handy countdown to Impending Doom to help you to plan what remains of your life. If you feel there is not enough time left to do all the things that you - or your children - might want to do, then we have also suggested some activities that may change the countdown to Doomsday, one way or another. Why settle for the one Doomsday Clock that other sites provide? - We've given you six. Scenario: Climate Change Global climate change is the predicted and observed result of increased heat being trapped in the oceans and the lower levels of the atmosphere. Human activity has resulted in a rapid rise in the level of atmospheric carbon dioxide, which is a known 'greenhouse gas'. CO 2 allows visible and near infra-red light to reach the surface of the earth, where it is re-radiated at longer wavelengths. However CO 2 absorbs these longer wavelengths and so traps the energy low in the atmosphere, causing it to warm up. This warming, combined with complex feedback effects, results in changes to atmospheric circulation patterns, leading to altered climatic conditions. Estimated time until irresponsible human activity causes a catastrophic change in global climate: Change the fate of the World!
