Cousin Mark goes to the trouble of reading the IPCC report so we don't have to. I looked up site after site and graph after graph on the points made in the report. For every claim made there is a counter claim. The statistics can be interpreted in many ways. But, let's suppose that all of the global warming enthusiasts are right and we are entering a significantly warmer period; is this a bad thing?
One of the many things that is constantly brought up is increased drought due to warming; this makes no sense. If the planet warms then that should cause melting of glaciers and the polar ice caps. If that occurs what is the impact? The impact is to release more water. Therefore, a warm period should be a wetter period. Glacial periods are the truly dry periods with low biomass; fewer plants and therefore fewer animals. Interglacial periods are the periods of plenty on the Earth. The Mesozaic era, the dinosaur period, was a time of a warmer planet than what we are in now, or likely to be in, even in the worst case scenarios. This period lasted some 180 million years and was a time of tremendous abundance in flora and fauna.
The only real problem that warming presents is a disruption of the status quo. Flooding of some low lying coastal areas, and perhaps inundation of some low elevation islands, like the Maldives. This is problematic for the people in the affected areas, but on a global issue we have to consider the impact on the human species, not individual humans.
So though I'm skeptical of global warming as a long term problem. I think we should hope for warming as opposed to cooling, which is what sunspot activity would predict.
