Picture This: Amazing Antarctic & Halloween Treats

Picture This: Amazing Antarctic & Halloween Treats

The weather news this week was of course dominated by remembrances of Hurricane Sandy and the impact it is still having on rebuilding and resiliency efforts, as well as climate research. A brewing storm that could bring snow to parts of the East was also much Tweeted about. But the most impressive pictures came from weather and climate-related even… Read More

An Ill Wind Blows in Antarctica, Threatens Global Flooding

An Ill Wind Blows in Antarctica, Threatens Global Flooding

The Southern Ocean's notoriously strong gales are growing stronger, and that's foreboding news for coastlines everywhere.… Read More

Expanding Antarctic Sea Ice is Flooding ‘Warning Bell’

Expanding Antarctic Sea Ice is Flooding ‘Warning Bell’

The spreading sheet of sea ice around Antarctica could be viewed as a napkin being draped over a monstrous water pistol. If, that is, the gelid napkin was a self-assembling machine that could reach beneath itself, aim the squirt gun at the planet’s shorelines, and squeeze the trigger. Research suggests that the expansion of Antarctic sea ice herald… Read More

Antarctic Sea Ice Officially Hits New Record Maximum

Antarctic Sea Ice Officially Hits New Record Maximum

It’s official: Antarctic sea ice hit its annual winter maximum on Sept. 22, reaching a record area of 20.11 million square kilometers (7.76 million square miles), the National Snow and Ice Data Center announced Tuesday. That maximum extent was 1.54 million square kilometers (595,000 square miles) above the 1981 to 2010 average extent, the NSIDC… Read More

Antarctic Sea Ice Hits New Max; Continent Still Warming

Antarctic Sea Ice Hits New Max; Continent Still Warming

The donut of sea ice encircling Antarctica is hovering around its yearly winter maximum area, and there’s little question that it’s going to set a record high this year. “Antarctic sea ice in 2014 is going to set a record for sure,” said Ted Scambos, a senior scientist with the National Snow and Ice Data Center in Boulder, Colo. This end-of-sea… Read More

Gravity Shift Reveals West Antarctic Ice Loss

Gravity Shift Reveals West Antarctic Ice Loss

The West Antarctic Ice Sheet is headed toward “unstoppable” collapse according to recent studies. A new visual released by the European Space Agency show what the start of that collapse looks like both for the mass of the ice sheet and its signature on the planet’s gravitational field. We think of gravity as a constant, holding us in place on the p… Read More

Warming Air Was Trigger for Antarctic Ice Shelf Collapse

Warming Air Was Trigger for Antarctic Ice Shelf Collapse

It was clear to anyone who went to Antarctica in the summer of 2001-02 that it was an unusually warm one — record-setting, in fact — and just one in a series of warm austral summers. In December 2001, geologic oceanographer Eugene Domack, now at the University of South Florida, was part of an expedition sampling the Southern Ocean seafloor around… Read More

Antarctic Riddle: How Much Will the South Pole Melt?

Antarctic Riddle: How Much Will the South Pole Melt?

One of the biggest question marks surrounding the fate of the planet’s coastlines is dangling from its underbelly. The melting of the Antarctic ice sheet has long been a relatively minor factor in the steady ascent of high-water marks, responsible for about an eighth of the 3 millimeters of annual sea-level rise. But when it comes to climate change… Read More
