Jeff Jacoby, a Boston Globe columnist, has written part two of his column on anthropogenic global warming. Here’s a link to the Jewish World Review. From the column:
Take the latest report of the Intergovernmental Panel on Climate Change. Unlike its previous report in 2001, which foresaw a possible rise in sea levels over the next century of around 3 feet, the new report cuts that figure in half, to about 17 inches. Why the revision? "Mainly because of improved information," the IPCC notes in the fine print. It goes on to note that even its latest estimate involves some guesswork: "Understanding of these effects is too limited to assess their likelihood." The science is getting better, but it's far from settled.
So, basically, the science is getting better and we’re learning more and more all the time. And the prospect that we can actually do something about climate change is still very much in doubt.
It’s well worth reading the whole thing. And here’s a link to part 1.
