MSCI 210 Lecture Notes - Lecture 19: Global Temperature Record, Thermohaline Circulation, Gulf Stream
Document Summary
It"s the sun: climate"s changed before, not bad, there is no consensus, etc etc. It"s the sun: the temperature of the earth is gradually increasing, however, the amount of sunlight has not increased. Ice is not floating, it is sitting on bedrock: when ice melts, sea levels rise, thermohaline circulation can shut down, ocean acidification. There"s no consensus: false, over 90% of scientists agree and know what the problem is. Rise in sea level and surface temperature. Down in sea ice: air temp has steadily increased since 1980. Models are unreliable: humans have an impact, temperature record is reliable. We can adapt: coral cannot, other species as well. Antarctica is gaining ice: a lot more areas that is losing ice. Climate change in the ocean: c02 is increasing in the atmosphere, seeing events that show climate change across the world, 3 indicators of a warming world sea levels. Incoming solar radiation: food levels will fall.
