Hot climate: good or bad?

There are some people who don't believe or don't care about climate change. A recent report show that Americans as the most greenhouse gas producers, hesitate if this climate change is because of human activities. Somebody said that this climate change in good for Sweden, since the country become warmer and more suitable to live!

Actually it could be true for Sweden and some other parts of the world. However, the global development is serious and scaring. In a recent report from World Meterological Organization, year 2010 showed to be the warmest year, and 2011 as one of the warmest. Actually, the last 13 warmest years have been in the last 15 years. This development is in parity with CO2 accumulation in the atmosphere. As you can see in this figure, the CO2 level has never been in this level (close to 400 ppm) in the last 400,000 years. So, we should expect the consequences and prepare for different disasters, believe it or not!
