logists studying global warming, even a drop of a few degrees worldwide can cause dramatic climate and physical changes, such as an increase in ice that make up the polar ice caps. This trend would decrease the growing seasons, or even wipe out one or more growing seasons altogether,creating massive worldwide crop failures Months later, the effect would switcharound – water vapor and carbon dioxide would increase, pushing a greenhouse effectover the global warming threshold. Temperatures would rise this time but suchwarming of the cooled down planet would probably be too late to rectify the global catastrophe. As the surface warming increased the humidity of the troposphere would increase the greenhouse effect Again, caught in a vicious cycle, the ocean would release carbon dioxide as it warmed. This thermal cycling of the planet would only strain the biosphere, decreasing the chances for all organisms to survive. In the midstof the tragedy, humans would be pushed to their limits trying to survive. The colder weather after the impact would kill crops; the repercussions would include the lack offood, including loss of livestock and wildlife. In turn, less available food would causestarvation worldwide. With this, disease would spread from the decay of the organismsthat were killed by the impact. Months later, the warmer climate generated asgreenhouse gases increased would only serve to exacerbate an already devastatingsituation. Ice caps would begin to melt and inundate the coastal towns and cities andpopulations would move inland. The heat would put strains on the atmosphere, creating droughts or drenching rains in many areas. Humidity would increase around the world, turning much of the remaining landmasses into tropical jungles. The additional atmospheric water would also increase the severity of storms causing extensive flooding and damage from wind and driving rains (Gettschalk 37). If an asteroid is determined ...
