NOAA discussion of global warming and paleoclimatology
There is some evidence that the earth is warming. The dispute that I have is why, and if any reduction of greenhouse gases will have any effect on the outcome.
Looking at the data on that site, which is run by career weather and climatologists, there appears to be evidence of warming. However, I raised several questions about the data collectioin methods on another thread, so I am not totally convinced.The scientific community is split on this issue, and therefore it should not be surprising that everyone in the government isn't on the same page. The only part of the report that I would dispute is the amount of contribution man-made causes have on warming. And even that can be looked at as coming primarily from the 19th and early 20th centuries, when smokestacks belched carbon into the atmosphere, before there was a public demand for clean air.
