As Earth’s climate marches toward equilibration with present-day CO2 levels, the climate will continue to warm. And this warming threatens the stability of a potentially much, much larger source for sea-level rise -- the world’s remaining ice sheets.]]> http://blogs.ei.columbia.edu/2013/06/12/400-ppm-world-part-2-rising-seas-come-with-rising-co2/feed/ 0 http://blogs.ei.columbia.edu/2013/06/06/lamont-scientist-featured-in-antarctic-climate-change-documentary/ http://blogs.ei.columbia.edu/2013/06/06/lamont-scientist-featured-in-antarctic-climate-change-documentary/#comments Thu, 06 Jun 2013 14:47:32 +0000 Kim Martineau http://blogs.ei.columbia.edu/?p=37159 Lamont-Doherty scientist Hugh Ducklow is featured in a documentary due out next summer on climate change and the West Antarctic Peninsula.

But creative vision, sweat equity, good partnerships and funding can bring dreams to reality, and 2013 delivered. It was four years ago that a small team of Lamont scientists, polar geophysicist Robin Bell, engineer Nick Frearson and ocean climate physicist Chris Zappa, began discussions of an instrument that could be used to collect measurements on polar ice during routine field-support flights in both the Arctic and Antarctic. It's called the IcePod.]]> http://blogs.ei.columbia.edu/2013/01/24/welcoming-a-new-instrument-for-probing-the-polar-regions/feed/ 2 http://blogs.ei.columbia.edu/2012/11/12/expanding-our-vision-brings-the-big-picture-into-focus/ http://blogs.ei.columbia.edu/2012/11/12/expanding-our-vision-brings-the-big-picture-into-focus/#comments Mon, 12 Nov 2012 17:47:47 +0000 Kirsty Tinto http://blogs.ei.columbia.edu/?p=32129 1500 feet above the ground surface is where our suite of instruments normally operates, but for this flight we are taking them up higher, much higher, in fact over 20 times our normal range to 33,000 feet.

We know from satellite data that Recovery and its tributaries have a deep reach, stretching well inland.
