Just got back from Alaska. On one leg of our cruise ship vacation we motored up Endicott Arm, (east of Juneau) and got up fairly close to the Daws glacier. (Got to hand it to the Captain, I would never have thought anybody would attempt to run a vessel of that size up through a snakey fjord filled with ice bergs, but he did). A lot of the passengers on this cruise seemed to hail from the south and the midwest. Every time a whale would spout or somebody would spot an eagle, a dolphin, etc there would be a chorus of oohs and aahs and cameras would be snapping madly. (The scenery was a lot like Puget Sound or SW BC, only a lot less populated, so it wasn't quite as stunning or surprising for residents of the Pacific NW). While stopped in sight of the glacier, one of the ship's Norwegian officers gave a lecture over the PA system about glaciers. How they form, why they're blue at the bottom, how many there are, etc. Everybody listened with at least moderate interest until the officer began mentioning the number of glaciers that have retreated substantially or disappeared in Glacier National Park during the last several years. You would have thought he had announced, "We support Hillary for president." The crowd got pretty lippy. Comments like "Who the hell is up on the bridge, Al Gore?" (and some worse) were frequently heard. It was pretty obvious that the negative reaction was *political*, not scientific. The telling moment, for me, occured when the officer mentioned that "as recently as 10,000 years ago much of the earth was covered by a sheet of ice." Once person standing immediately behind me grumbled "Not according to the Bible!", and another bystander confirmed that sentiment by stating, "I guess it all depends on what you believe." Indeed. As always, a solid belief or disbelief is unlikely to be swayed by anything as trivial as actual evidence- on either side of the question. What was interesting was the Eagle Glacier outside Seward, AK. There are markers as you hike the trail to the glacier of where the face was over the years. From 1917-1926 was the major retreat. Maybe 300 yards. Tells me it is not all mankinds fault.- Hide quoted text - - Show quoted text - It's normal for individual glaciers to advance and retreat. Always has been, for millions of years. What is so unusual about current global climate conditions is that nearly all glaciers are receding at once. Many are disappearing entirely, and no new glaciers are appearing to take their place Yes, there *are* exceptions to the prevailing conditions of glacial retreat, just enough to prove the rule. I don't know how much of it, if any, is mankind's fault--- but the results will definitely be mankind's problem. Nobody is well served by side-tracking this scientific concern into an "us vs. them" political snot fight. If things come down as they well might, nobody is going to be spared the consequences simply because he or she voted for the prevailing candidate in the most recent election. Chuck, I was following up on SWF's statement that 50% of scientist did not believe that there was Global Warming. I thought it was the opinion of the vast majority of climatologist that global warming was a fact, and the only controversy was the cause of global warming. I found this interesting article on the "Global Warming Controversy". It seemed to be a fairly unbiased review of the differences of opinion. There seems to be more scientist than i realized who question the accuracy of the statistics concerning global warming in relationship to historical data. http://en.wikipedia.org/wiki/Global_...g_controversy- Hide quoted text - - Show quoted text - We can't possibly be reading the same article. Lead statement in the item you linked: "The existence of a rise in average temperatures since the mid-19th century is not disputed. The controversy focuses on the specific causes of the recent warming, and concentrates on the warming after World War II; the likelihood and magnitude of future warming; and whether additional warming would be harmful or beneficial." **** Another statement in the item you linked (under Scientific Concensus) "The American Association of Petroleum Geologists is the only scientific society that rejects the predominant opinion.[19][20]" ************************* And then there's this account of a person who reviewed 928 scientific opinions on the subject, was initially rebuked by another reviewer, and how the rebuking reviewer has apparently backed off once the desired publicity and talking points were generated: (The supposed de-bunker retreated to a position stating, "Yes there is a overwhelming majority of scientists in agreement on globl warming issues, but it is far from unanimous".... When was the last time, except in a murder trial, that *everybody* had to agree before the position of the majority could be found credible?) From your site: "A 2004 essay by Naomi Oreskes in the journal Science reported a survey of abstracts of peer-reviewed papers related to global climate change in the ISI database.[21]. Oreskes said: Some corporations whose revenues might be adversely affected by controls on carbon dioxide emissions have also alleged major uncertainties in the science. Such statements suggest that there might be substantive disagreement in the scientific community about the reality of anthropogenic climate change. This is not the case. The scientific consensus is clearly expressed in the reports of the Intergovernmental Panel on Climate Change (IPCC). Oreskes stated that of the 928 abstracts analyzed, "Remarkably, none of the papers disagreed with the consensus position". Benny Peiser claimed to have found flaws in her work, writing " Oreskes, a professor of history, claims to have analyzed 928 abstracts on global climate change, of which 75% either explicitly or implicitly accept the view that most of the recent warming trend is man-made. When I checked the same set of abstracts [plus an additional two hundred found in the same ISI data bank], I discovered that just over a dozen explicitly endorse the "consensus," while the vast majority of abstracts does not mention anthropogenic global warming. [22] " In order to include only "hard science" papers rather than opinion pieces or editorials, Oreskes excluded the Social Sciences Citation Index and the Arts & Humanities Citation Index and set the search to include only Articles, while Peiser searched for all document types in all indices,[23][24] and the interpretation of the remaining parts of his attempted refutation is further disputed.[25] In a later op-ed piece in Canada's National Post, Peiser makes no further reference to his review [26]. Peiser also stated: " ...the overwhelming majority of climatologists is agreed that the current warming period is mostly due to human impact. However, this majority consensus is far from unanimous.[24]" ************************************************** ************************* According to the site you linked, your initial impression that most scientists are in general agreement about global warming is probably more accurate than a revised impression that the scientific ranks are split 50-50 or so on this issue. Unless, of course, 50% of the scientists belong to the American Association of Petroleum Geologists. :-) |
