Greenland Glacier 4X Size of Manhattan Breaks Loose

This really struck me as a fascinating piece of science news:

A University of Delaware researcher reports that an “ice island” four times the size of Manhattan has calved from Greenland’s Petermann Glacier. The last time the Arctic lost such a large chunk of ice was in 1962.

“In the early morning hours of August 5, 2010, an ice island four times the size of Manhattan was born in northern Greenland,” said Andreas Muenchow, associate professor of physical ocean science and engineering at the University of Delaware’s College of Earth, Ocean, and Environment. Muenchow’s research in Nares Strait, between Greenland and Canada, is supported by the National Science Foundation (NSF).

These sorts of things are not the usual run if the mill events . . .

Climate Change: The Scientific Debate

Quite interesting, even handed, and intelligent:

Part 1 Climate Change — the scientific debate

A basic look at how climate scientists infer that man-made carbon gases are changing the climate, and how this view is contradicted by other climate scientists who are skeptics.
I am a former science correspondent with an interest in reporting the facts, not the media hype. My thanks to 9thgate for checking my script for errors.

Part 2: Climate Change — the objections

This video, the second in the series, looks at alternative hypotheses explaining global warming. I am only looking at alternative hypotheses put forward by real, professional climate researchers, and the findings of real, professional climate researchers who disagree with them. Yes, I’ve left a lot of the detail out. This is a 10-minute video summarizing the arguments and counter-arguments, not a PhD thesis. The comments forum will be free and open, as always, but if you disagree with what real, professional climate scientists say, please take it up with them and dont expect me to defend their point of view. If you have a stunning piece of scientific evidence that disproves one side or the other, dont waste time on my channel, write a paper, and get it peer-reviewed and published in a reputable journal.

Part 3 – Climate Change — Anatomy of a myth

I had planned to put several myths in this video, but discovered such an appalling web of deceit and fabrication in this first one that I felt I had no choice but to thoroughly debunk it. Like many ingrained myths, this one is so ubiquitous that it takes an awful lot of hard evidence to convince true believers that it’s been fabricated.

Coming soon: Parts 4 5 & 6

How Bad is BP Deepwater Horizon?

Here is a decidedly contrarian viewpoint, from University of Alabama Professor Dr. Roy Spencer. Prof Spencer notes that the general commentary regarding the BP spill as “the worst environmental disaster in history” is wildly overblown. His graph below is designed to put this spill into perspective. Now, before you wail that he is a global…Read More
