A group of environmental scientists and the United Nations has discovered the sun is causing much of the global warming we experience today. “We’ve suspected this for some time,” said IPCC regular contributor Gordy Columbo. “But there was no way to prove it. Now we can.” The scientists checked the temperature of the atmosphere in the daylight, when the sun was shining, and at night, when the sun was not. Amazingly, they found the daylight temperatures to be much warmer.
