An international team of scientists, drilling deep into the ice layers of Greenland, has found DNA from ancient spiders and trees, evidence that suggests the frozen shield covering the immense island survived the earth's last period of global warming.
The findings, published today in the journal Science, indicate Greenland's ice may be less susceptible to the massive meltdown predicted by computer models of climate change, the article's main author said in an interview.
"If our data is correct, and I believe it is, then this means the southern Greenland ice cap is more stable than previously thought," said Eske Willerslev, research leader and professor of evolutionary biology at the University of Copenhagen. "This may have implications for how the ice sheets respond to global warming. They may withstand rising temperatures."
How can that be? After all, soon-to-be-Dr. Al Gore – who has had absolutely no training in the relevant areas of science despite the media belief that he is indeed the foremost expert on the subject – says Greenland is going to thaw in the near future with devastating repercussions. Surely he can’t be wrong:
A painstaking analysis of surviving genetic fragments locked in the ice of southern Greenland shows that somewhere between 450,000 and 800,000 years ago, the world's largest island had a climate much like that of Northern New England, the researchers said. Butterflies fluttered over lush meadows interspersed with stands of pine, spruce, and alder.
Greenland really was green, before Ice Age glaciers enshrouded vast swaths of the Northern Hemisphere.
Wait. Isn’t the debate over and the science settled on this issue? It appears not:
More controversially -- and as an example of how research in one realm of science can unexpectedly affect assumptions in another -- the discovery of microscopic bits of organic matter retrieved from ice 1.2 miles beneath the surface indicates that the ice fields of southern Greenland may be more resilient to rising global temperatures than has been forecast. The DNA could have been preserved only if the ice layers remained largely intact.
A scenario often raised by global warming specialists is that Greenland's ice trove will turn liquid in the rising temperatures of coming decades, with hundreds of trillions of gallons of water spilling into the Atlantic. This could cause ocean levels worldwide to rise anywhere from 3 to 20 feet, according to computer projections -- bad news for seaport cities like Boston.
But the discovery of organic matter in ice dating from half-a-million years ago offers evidence that the Greenland ice shield remained frozen even during the earth's last "interglacial period" -- some 120,000 years ago -- when average temperatures were 9 degrees Fahrenheit warmer than they are now. That's slightly higher than the average temperatures foreseen by most scientists for the end of this century, although some environmentalists warn it might get even hotter.
Incredible. And, as many scientists have been claiming regardless of such falling on deaf press ears, this indicates just how nonsensical and worthless climate models proclaiming imminent planetary doom are:
Researchers from the Danish-led team said the unanticipated findings appear to fly in the face of prevailing scientific views about the likely fate of Greenland's thickly-layered ice, although Willerslev stressed that the findings do not contradict the basic premise that the earth's temperature is rising to worrisome levels, with gases emitted by industry, cars, and other human activity playing a big role.
"But it suggests a problem with the [computer] models" that predict melting ice from Greenland could drown cities and destroy civilizations, according to Willerslev.
