Does this look familiar?
Big Freeze: Earth Could Plunge into Sudden Ice Age
Yes, they have done it again. Maybe another ice age is coming. Or maybe not. We rarely learn from the past, and it is clear the media hasn't either.
Starting roughly 12,800 years ago, the Northern Hemisphere was gripped by a chill that lasted some 1,300 years. Known by scientists as the Younger Dryas and nicknamed the "Big Freeze," geological evidence suggests it was brought on when a vast pulse of fresh water - a greater volume than all of North America's Great Lakes combined - poured into the Atlantic and Arctic Oceans.
This abrupt influx, caused when the glacial Lake Agassiz in North America burst its banks, diluted the circulation of warmer water in the North Atlantic, bringing this "conveyer belt" to a halt. Without this warming influence, evidence shows that temperatures across the Northern Hemisphere plummeted.
No time to react
Previous evidence from Greenland ice samples had suggested this abrupt shift in climate happened over the span of a decade or so. Now researchers say it surprisingly may have taken place over the course of a few months, or a year or two at most.
Wow! You mean this is a natural occurence?
The e-mails from a British university's climate center were obtained by computer hackers and posted online about two weeks ago. Climate change skeptics contend the messages reveal that researchers manipulated and suppressed data and stifled dissent, and conservative bloggers are dubbing it "Climategate."
In the first Capitol Hill airing of the issue, House Republicans Wednesday read excerpts from at least eight of the e-mails, saying they showed the world needs to re-examine experts' claims that the science on warming is settled. One e-mail from 2003 was by John Holdren, then of Harvard University and now the president's science adviser.
The exploding controversy led Phil Jones to step aside as head of the climate research unit at the University of East Anglia, the source of the e-mail exchanges. The university is investigating the matter. Penn State University also is looking into e-mails by its own researcher, Michael Mann. House Republicans asked for a separate hearing or investigation into the issue, but were rebuffed by Democrats.
What a surprise, Michael Mann is going to investigate his own emails. I am sure he will be thorough and unbiased....
