Atmospheric Carbon Dioxide Concentration is increasing.
Sea-surface Temperature is also increasing.
There have been climatic changes overall.
Frequency of Hurricanes is increasing.
The Extent of Sea Ice is decreasing. So people who don't believe in Global warming..tell me one good reason why I should believe you?
Scientists don't just sit there and waste their time to run experiments, analyze data, come up with calculations, and others types of procedures just for nothing. These are environmental scientists, engineers, physicists that give a damn about the earth that they live on. They have a love for science and I would hope that they like what they are doing.
I found this image online... In the picture above the ice sheets in Alaska near the coast are decreasing. In July 2006, you can see how much ice is there. Then in July 2007, there aren't any at all. Now the black areas are all open water. This is evidence of global warming from the Obama White House which President BUSH tried to hide from America.
