Narcotic effect of Carbon Monoxide (CO)

Developing of a society usually is in parity of developing more stress for the people. We have to work harder and harder, and also we affect our environment in different ways. A more developed society usually means also more thermal load, more traffic jams, more noise, more CO2, and more discomfort. People are used to say "it was better before".

There was a recent study on these factors and how they affect the human stress. One interesting point is the level of carbon monoxide (1-15 ppm), which act as narcotic for people living in the heart of the cities and reduces their stress. So, we shouldn't surprise if we see CO addicted people in the cities in line of other drugs :)

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!
