This week in the journal Nature scientists give the most comprehensive view of thinning ice sheets in Greenland and Antarctica to date.

Scientists from British Antarctic Survey (BAS) and the University of Bristol analyzed 50 million satellite measurements (from NASA) to show the massive ice loss on these polar giants.

The result are surprising, even to the scientists.

The break up of the Arctic ice sheet–now at record levels –might make an Arctic crossing much easier for a small group of previously untracked Right Whales. And that’s the problem. The Arctic ice-sheet break up is making the “Northwest Passage” across the Pole much easier for everyone–including commercial fishing ships. If this newly discovered group of whales decides to take this short cut (heading south for the Winter), scientists fear, they could swim headlong into the newly opened shipping [...]

Scientists studying northeastern Greenland’s hairy, meat-eating wolf spiders have discovered every arachnophobe’s worst nightmare.

It appears that as the Earth has been warming and summers have been getting longer, the 8-legged hunters have been steadily growing larger and more numerous. And it’s likely that other creepy-crawly species around the world could be growing larger too.

This month, as the results of data analyses come in, climate scientists are getting a more detailed, far clearer picture of the ‘State of the Poles’ and the effects of warming and climate change in these most extreme regions of our planet. Although this project is actually the culmination of two years work (encompassing 160 separate studies and costing 1.2 billion dollars) it has been officially deemed the ‘International Polar Year’ (IPY).

One of the most important findings of this project is a confirmation of what many climate scientists have suspected for a couple of years now–that the impact of climate change on our environment is happening at a much faster rate than previous computer models predicted. This is true even for the four major reports released by the Intergovernmental Panel on Climate Change (the last of which was released in 2007).

Hosting a national radio talk-show, Steele offered a curious interpretation of history, climatology, and coalition building.

Friday the 13th just got a little scarier. Here are 13 facts about the realities of global warming.

The numbers speak for themselves — we must make 2009 the showdown year for global warming action. There is no time to lose.

35%

Increase in the global carbon dioxide emissions from the burning of fossil fuels since the Kyoto Protocol was signed in 1992.

388.57 ppm

Average concentration of carbon dioxide in the atmosphere in May 2008, a record high.

541 – 970 ppm

The projected concentration of carbon dioxide in the atmosphere by 2100 under a business as usual scenario where we don’t dramatically reduce global warming emissions.

260 – 280 ppm

Average concentration of carbon dioxide in the atmosphere before industrial emissions.

President Bush has urged Senators to initiate legal procedures to stakes claim to the natural resources of the Arctic region.

$268 bottle of water, anyone? Going once… going twice….

Just as growth in the US bottled water market is finally dropping off, Greenland has made the bewildering move to bottle and export 1 to 3,000 year old water that it will drill from icebergs. To add insult to environmental injury, Greenland will market its product as “sustainable.” Just how much marketing sense went into the idea to bottle the climate-induced melt from Greenland’s glaciers in plastic and ship it with a heavy carbon footprint stamped firmly into each “sustainable” bottle is anyone’s guess.

Over the past few years we have sadly had to watch the Arctic ice concentrations drop significantly. Focus has been primarily centered on the Arctic Circle, but Greenland is also suffering from the increased global temperature.

And now, thanks to researchers from the Delft University of Technology in the Netherlands and the Center for Space Research (CSR) in America, a new and accurate picture of Greenland’s shrinking ice cap has been formulated.

Subsequently, the researchers have found that Greenland is currently responsible for an annual increase of sea levels of up to half a millimeter.

Ever since I first saw Ernie and almost the entire felt-cast of Sesame Street do “The Rubber Duck, Duck” dance on Sesame Street, I have had a strange fascination with rubber ducks. They aren’t the common toy here in Australia that they appear to be elsewhere. And though looking back at that video now presents me with a bit of a moral and architectural dilemma, considering just how many people are naked together in that tub, my love for the rubber duck continues.

And now, once again, the rubber duck is coming to the aid of science. US rocket scientist Alberto Behar of NASA’s Jet Propulsion Laboratory in California has sent 90 rubber ducks into the Jakobshavn Glacier in Greenland in an attempt to figure out what is happening inside Greenland’s fastest moving glacier.

Fears about the Arctic melting away during northern summers are proving to be far from unfounded, with the latest reports rolling in from Alaska and Greenland showing disturbing trends. New shipping lanes are opening up through what were once icy seas near Alaska, and glaciers that have so far withstood much of what the environment has thrown at them in Greenland, are showing signs of breaking… literally.

Researchers who have been monitoring daily satellite images of Greenland’s glaciers from Ohio State University have discovered break-ups at two of the largest glaciers within the last month.
