Wind-Blown Antarctic Sea Ice Helps Drive Ocean Circulation 

Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than anyone

Something to Show your Neighbor Who Thinks Climate Change is a Hoax 

One of the most common claims (by those who got their education about atmospheric physics staring at a computer screen in the basement) is that the increase in Antarctic Sea ice proves the planet is not warming. This myth is surprisingly widespread and persistent, and frequently gets mentioned on national news outlets that cater to people with a particular world view. Peter Sinclair, and the folks at the Yale Forum

Clarity on Antarctic sea ice. 

I’ve always been a skeptic when it comes to Antarctic sea ice. I’m not referring here to the tiresome (and incorrect) claim that the expansion of sea ice around Antarctica somehow cancels out the dramatic losses of sea ice in the Arctic (NB: polar bears don’t really care if there is sea ice in Antarctica

More ice in a warming world 

     Antarctic sea-ice coverage has increased over the past few decades. A new study explains why this is the case, why models do not capture the increase and what humans might have to do with the expanding ice cover. In September 2014, Antarctic sea ice covered more than 20 million square kilometers for the first time since the beginning of continuous

Unforced variations: July 2014 

This month’s open thread. Topics of potential interest: The successful OCO-2 launch, continuing likelihood of an El Niño event this fall, predictions of the September Arctic sea ice minimum, Antarctic sea ice excursions, stochastic elements in climate models etc. Just for a change, no discussion of mitigation efforts

Geosciences column: Playing back the Antarctic ice records 

Satellites are keeping tabs on the state of Arctic and Antarctic sea ice, and have observed considerable declines in ice extent in many areas since records began, but what do we know of past sea ice extent? Ice cores keep an excellent record of climate change, but until recently, ice cores have not been used

Antarctica: Ice Mass Decline 

Although a lot of media hype focused on an Antarctic sea ice increase early this year, an international team recently documented that the continent is experiencing a net loss in ice

The ‘Skinny’ on Antarctic Sea Ice 

One piece of our IceBridge mission focuses on sea ice here in the south. Sea ice in the northern regions has been reducing at dramatic rates over the last decade, setting a new record just this year, but the story in the south is not so clear. In fact, there has been a buzz that
