All Global Warming, All the Time
This recent story from the People's Republic of Boulder caught my eye. What I really liked is the never say die attitude of the researcher, Ian Howat, who is with both the University of Colorado's National Snow and Ice Data Center and the University of Washington's Applied Physics Laboratory. I'm sure he is an accomplished scientist. He also definitely knows what side of the bread the butter goes on (and it is not big oil butter).
His report shows the [two] glaciers [on Greenland] shrank dramatically and dumped twice as much ice into the sea during a period of less than a year between 2004 and 2005.
But then, fewer than two years later, they returned to near their previous rates of discharge.
Got that? The two glaciers melted a lot for a year and then stopped melting so much over two years.
Ian draws the logical conclusion: Our main point is that the behavior of these glaciers can change a lot from year to year, so we can't assume to know the future behavior from short records of recent changes.
Very wise, Ian. But he does not give up on global warming: Future warming may lead to rapid pulses of retreat and increased discharge rather than a long, steady drawdown.
Like most scientists of the global warming (cpbha) persuasion, he assumes the lack of increased melting (return to normal) is just another symptom of global warming. The Warmie tactic is to claim every possible weather condition is further proof of global warming and we just witnessed that tactic here.

Yeah, I've been reading about this--a more active sun 'chases away' the cosmic rays which cause cloud cover which cools Earth, and the absence of which clouds promotes warming. OK, I'm willing to believe that. So the more active sun we've had lately, which does not have enough added candlepower to account for the slight warming we've seen, accounts for it with less cosmic ray generated cloud cover. I just don't know why I didn't see that before. (sarcasm)It does fit the facts though. We'll see if the Swedes are right, assuming of course they are allowed to speak ill of Global Warming (cpbha). Thanks for the link.
