Thanks Mike and Dennis...is just what I wanted. I'll send the link to my sister who is in some debate on some web site. She is not a scientist but is mixed up in the New Urbanists and they were involved in reconstruction design for Mississippi Gulf coast...where sea level predictions as well as storm strength predictions have to be accounted for.

Dennis: OK, I'll grant you the temperature drop could be (but not certain) related to solar activity in early 20th century. But, look at the amplitude of that vs. the overall warming until now. Greenhouse gasses are likely to swamp the effects of the sun unless the sun does something really enexpected.

I just read a discussion in Nature or a paper in Nature; when I read the paper itself, I'll post on their idea that natural ocean cycles in the next decade will cancel the effects of warming around at least the North Atlantic. I imagine if the are correct, and that is a big IF, then the earth will get clobbered after that.
