For our third class we were asked to find an issue/problem/solution in the news and summarize it in class. I would like to talk about the issue I found on http://www.enn.com/ called "Feedback Accelerates Arctic Ice Melt" which talks about research published in 2009 by Nasa and the National Snow and Ice Data Center. They studied the arctic ice sea melt season from 1970-2009. The season is now 20 days longer, melting earlier and freezing later. The ocean water absorbs more heat than the snow/ice because of the albedo effect, so the water keeps getting warmer and warmer creating thinner and less ice each year. Some people don't realize the amount of impacts this can have on the globe like; warming ocean temperatures, rising sea level, warming atmosphere temperature, arctic animals habitat destruction, arctic tree line receding north, warmer fall temperatures, and others. This problem was related to many that were discussed in class and it is alarming to think about what is happening to our earth. It most definitely has something to do with human pollution and CFC's being released into our atmosphere, but I think that there are other contributing factors. The big question on my mind is because it is a loop and it will continually get worse what can we do other than reducing pollution to try and stop it?
