A fascinating press release I want to pass along.Â At first I thought it was maybe good news in that rising sea levels would slow glacier drainage into the oceans but the affect is the opposite: For the first time, researchers have closely observed how the ocean's tides can speed up or slow down the … Continue reading Satellites Observe “Traffic Jams” in Antarctic Ice Stream Caused by Tides
Dear Readers, Find below an interesting press release I may as well share verbatim: The rapidly melting ice sheets on the coast of West Antarctica are a potential major contributor to rising ocean levels worldwide. Although warm water near the coast is thought to be the main factor causing the ice to melt, the process … Continue reading Caltech: Robotic Ocean Gliders Discover Why Antarctic Polar Ice is Melting
A commenter on the most recent edition of het's AWOGWN asks an interesting set of questions: How would temperature data have been seen during the last 10,000 years prior to the peak of each of the previous Milankovich cycles? What caused the temperature to reverse course in those cycles and why would we not expect … Continue reading What did temperatures do as the last glacial minimum ended 120K years ago?
Here are a couple of great animations of the arctic sea ice volume over the satellite era. (credit to Andy Lee Robinson, seen at Planet3) While this is not news, I think the animations make two things very clear.Â One, is that anyone even giving the time of day to the notion that there is … Continue reading Ice animations
Negative brownie points to anyone who feels it necessary to point out that penguins and polar bears do not cross paths in the wild!Â (Oops, I guess that would include me...) (cartoon courtesy of Alex Hallatt, Creator of Arctic Circle cartoons)
Thingsbreak has a great overview of recent research on ice loss in the Antarctic (east and west) and Greenland. For anyone who has had enough of the freedom vs responsibility of the press discussion (mandas?), perhaps there are some interesting bits in Thingsbreak's post to mull over. I have posted on sea ice dynamics before … Continue reading Ice sheet overview
Okay, so this one is a bit of a tear-jerker and I usually like to avoid mixing sentimentality with environmentalism, but it is very informative and interesting if sad. It is greenman3610's Climate Crock of the Week from about three weeks ago and as usual well worth watching. I tend to be skeptical about anthropomorphizing … Continue reading CCW – Extinction: It’s not just for Polar Bears anymore
