Seriously, you hear some bullshit fake research about the weather rising up in 1905? Come on, who believe that crap. It's 2009 and we can't even predict the weather properly.
What's obvious is that emissions occur and there's a lot of mega cities. The world is a small place in comparison. Over time this would effect the climate.

Don't criticize research until you look at it yourself, and compare it's merits and faults for yourself. We know what the temperatures were in 1905, we know what the Co2 levels were in 1905. The instruments used to measure those phenomena are the same now as they were then. Factually, 1905 was a cooler year than normal.
Human contribution to Co2 levels adds up to approximately .12 percent annually. That is not a significant amount. Current levels are about 480 parts per million by volume, which is about 1% of their historical high. And, even when Co2 was at that historic high, there was still ice in the world, and life thrived on land and in the sea.
As for other things like "mega cities", yes, they affect the environment, but only locally. Their effect is offset by other man-made things. Man is growing wheat, barley, and corn crops on vast amounts of farmland. These crops offset the temperature increases caused by city "hot-spot islands". Added to these farms are the vast lakes and reservoirs created by artificial dams.
Natural occurrences still outweigh man's contributions to the weather. The eruption of a single volcano can surpass decades of man-made air pollution.
Please try to come up with an intelligent question or statement, no more empty-headed comments.
