Climate: Is the science settled?

The climate alarmists are telling you that global warming is real. It's caused
by humans. The greenhouse theory is a proven fact. They say 97 of
science agrees with it. People who discount it say that it's exaggerated for political reasons. But there are other factors which are affecting the weather: cloud cover, wind direction, ocean currents, the strength of the Sun, and a significant number of scientists disagree with the 'greenhouse theory', probably many more than three percent.
