NASA: global warming is about water, not hot summers

Given our government's stubborn, ignorant approach to global warming, it is difficult to explain why NASA keeps putting out such great material on the subject.

Their latest entry is this article, in which the scientists announce that "it's not too difficult to push the climate to a warm state" and predict that, should it occur, the mid-latitudes will probably be "a lot dryer." They emphasize that water's availability and distribution will be the challenges and hallmarks of global warming.

For an even less cheerful read, check out the highlighted article on boreal forests on the same page. It closes with the morbid observation that the "turning point" for those forests may be close at hand.

Another very critical point in this article is that it will be difficult to confuse these changes with anything but global warming. The change in sea-surface temperature, the rapid decline of lower trophic-level organisms (zooplankton), and other characteristics of the ocean environment are often explained away as natural decadal cycles and not signs of global warming. This article is referencing a article in Nature (10 August) which follows a previous article by this group reported in Nature (1 June) that discusses the details of temperature changes in the north pole during the Palaeocene/Eocene thermal maximum.
