S. Fred Singer, Ph.D. in physics is an atmospheric and space physicist. What is the impact of a warmer climate? It's not the warming itself that we should be concerned about. It is the impact. So we have to then ask: What is the impact on agriculture? The answer is: It's positive. It's good. What's the impact on forests of greater levels of CO2 and greater temperatures? It's good. What is the impact on water supplies? It's neutral. What is the impact on sea level? It will produce a reduction in sea-level rise. It will not raise sea levels. What is the impact on recreation? It's mixed. You get, on the one hand, perhaps less skiing; on the other hand, you get more sunshine and maybe better beach weather. Let's face it. People like warmer climates. There's a good reason why much of the U.S. population is moving into the Sun Belt, and not just people who are retiring.
