Global good?

I linked before to this good essay (with 40 plus comments) by Donald Sensing, but it’s worth doing it again. It answers a good question about Global Warming, one you’re not likely to hear in the doomsday "debate" and furor: What if the warming is a good thing? Rising oceans can’t be good, they say, but they won’t rise in an afternoon, but over many decades, allowing plenty of time to build Dutch-like dikes, for one thing. But what if the warming produced more arable land in the Third World, helping them to feed themselves better than they do now? What if, in other words, Global Warming is a good thing?
