Digg front page item shows a very cool (sorry) NASA photo of Great Britain covered with ice from orbit.
Global warming promoters have long said that the gulf stream is at risk. For example, this 2002 Science Daily story, “A Current Controversy: Is Europe About To Freeze?,” excerpt:
“One of the odd possibilities that could emerge from global warming is that much of Europe, robbed of the ocean current patterns that help keep it warm, could rather abruptly enter a deep freeze and have a climate that more closely resembles Alaska than the modest temperatures it now enjoys.”
There are critics of that theory, including the author of this article, “Climate mythology:
The Gulf Stream, European climate and Abrupt Change.”
One proposal to combat increased temperature in urban heat islands is to paint roofs and other city surfaces lighter colors to reduce absorption of sunlight.
The scientists at Vangelis (heh) say the Earth’s albedo is 0.39. If the Earth’s surface was a perfect mirror, the albedo would be 1.00, with all light hitting it reflected back to space. I wonder if all that reflected sunlight from frozen Europe and most of the U.S. covered in snow is a negative feedback fighting global warming.
If so, residents of the American Southwest can keep driving their SUVs forever. Drill baby, drill! (That was sarcasm).
