Global warming settling

Chris Horner at Planet Gore argues that if the science of global warming is "settled," therefore money spent researching the matter is wasted. That's so obviously wrong it's probably not even worth a comment, but I'll point out that establishing the existence of anthropogenic global warming only begins to tell us what we need to know about such matters as its severity, duration, ongoing changes and, above all, what we should do about it. That's about where things stand in climate science, and arguing we should shut down the science is gross know-nothingism. Also, by Horner's logic, if the science actually isn't "settled," we should spend money on it, no?
