This is the nature of science, and a major reason why transparency is such an issue. Scientists test each other's theories all the time.
In the case of Killimanjaro, Gore has been using the image of its vanishing snow pack to illustrate the catastrophic changes AGW is allegedly causing.
Turns out, it's not so much AGW as natural cyclical climatic change.
Leon DeWinter of Pajamas Media covers the story.
Professor Sinninghe Damste’s research, as discussed on the site of the Dutch Organization of Scientific Research (DOSR) — a governmental body — shows that the icecap of Kilimanjaro was not the result of cold air but of large amounts of precipitation which fell at the beginning of the Holocene period, about 11,000 years ago.
The melting and freezing of moisture on top of Kilimanjaro appears to be part of “a natural process of dry and wet periods.” The present melting is not the result of “environmental damage caused by man.”Correct me if I'm wrong, but I'm pretty sure there weren't any cars, factories or airplanes 12,000 years ago. And yet, Killimanjaro was ice-free. How can this be?
Professor Damste studied organic biomarker molecules in the sediment record of Lake Challa, near Mount Kilimanjaro, and reconstructed the changes and intensity of precipitation in this part of Africa over the last 25,000 years. They observed an 11,500 year cycle of intense monsoon precipitation.
In the dry period between 12,800 and 11,500 years ago, Kilimanjaro was ice-free.
The AGW house of cards is collapsing around his ears, and what is his response to it all? According to the Times Online, Copenhagen isn't going to do enough, in Al's opinion.
The last paragraph in the article is the best:
He also brushed aside questions over the reliability of climate science that have followed the publication last month of leaked e-mails between climate experts. He claimed that the scientific consensus around climate change “continues to grow from strength to strength”. He added: “The naysayers are in a sunset phase with a spectacular climax just before they subside from view. This is a race between common sense and unreality.”For once I agree with the High Priest of Gaia - this really is a race between common sense and unreality. He is just confused as to who is suffering in unreality and who is showing common sense. But, then again, it seems to be the the M.O. of his crowd - when in doubt, ridicule, shout down opposition, and make them seem crazy and fringe. Climategate is destroying the 'science' he has built his carbon credit scam on, but it's the 'naysayers' who are in a "sunset phase" and are going to soon "subside from view".
His 'facts' are being shot down left and right, but we are the ones in denial.
Sure, Al. Whatever you say.
