Actually, there is indeed global warming. But it isn't caused by humanity and it's quite natural. And it's happening on Mars too. The real cause is increasing output by the sun. People tend to forget that we're still coming out of the last Ice Age. The sun's output increases and decreases in cycles which last thousands of years, leading to increases and decreases in the Earth's average temperature. This is something I was taught in grade school. But today's socialist, leftist pseudo-scientists focus strictly on the change in temperatures over the past few decades only, and draw a completely flawed conclusion which is in line with their flawed thinking and ideology. They concentrate on a single tree and fail to see the entire forest.
In addition to the sun's cycles, there are also cycles of increased hurricane activity. We're in such a cycle right now, which actually began a decade ago. But the average leftist only looks back as far as the year 2000, and seeks to explain everything based on the Bush presidency.
