Antarctic Scientists Honor Obama by Collecting Climate Data
Researchers studying the West Antarctic Peninsula marine ecosystem will recognize President Obama’s efforts to combat global warming by collecting climate data at an oceanographic station they named for the 44th president.

Looking at Climate from All the Angles
The Earth Institute digs into the past, tracks the present and models the future of climate. We explore the broader issues surrounding climate change, seek ways to apply our knowledge to real solutions, and nurture collaboration among faculty and researchers in the natural sciences, social sciences and humanities, law, public health, engineering, architecture and urban…

The ‘Bird’ Has Flown!
The ‘bird’ has flown! Voices are raised in celebratory cheers from the southernmost continent to across the U.S. Our first ALAMO float is deployed! Now we can begin to answer some of the big questions on this mysterious ice/ocean interface.

Antarctica Has a New Explorer in the Water Near a Key Ice Shelf
The first of six ALAMO floats parachuted into the Ross Sea off Antarctica to begin profiling the water in a check for areas where warmer than normal water could put the Ross Ice Shelf at risk.

‘Ghost Ice Shelves’ and the Third Antarctic Ice Sheet
The Antarctica Peninsula has been referred to as Antarctica’s third ice sheet. Following behind the East and West Antarctic ice sheet in size, one might be inclined to minimize its importance in the effects of melting Antarctic ice, on changes in sea level and other impacts, but that would be an imprudent mistake. The peninsula…

The Domino Effect
Ice shelves can behave like dominos. When they are lined up and the first one collapses it can cause a rippling effect like dominos. We have seen this with the Larsen Ice Shelves. Named in series, the Larsen A, B and C shelves extended along the northeastern edge of the West Antarctic Peninsula, and covered…

Year by Year, Line by Line, We Build an Image of Getz Ice Shelf
Changes in Antarctic ice have been dominated by the interaction of the ice and the ocean, and because ice shelves extend out into the water they are vulnerable to melt from the warmer ocean water. Melt can affect them in two ways, through thinning along their length and through causing a retreat of the “grounding…

What Happens to Ecosystems When Antarctica’s Ice Melts?
A special section in the October issue of BioScience featuring research by Lamont-Doherty Earth Observatory scientists examines the effects of intense melting on two Antarctic ecosystems, tracking impacts all the way from microbial food webs to shifting penguin populations.

Ancient Leaves Link Loss of Antarctic Ice to a CO2 Spike
Twenty-three million years ago, the Antarctic Ice Sheet began to shrink, going from an expanse larger than today’s to one about half its modern size. Ancient fossilized leaves retrieved from a lake bed in New Zealand now show for the first time that carbon dioxide levels increased dramatically over a relatively short period of time…
The first Earth Day in 1970 ignited a movement to stop polluting our planet. Today, our scientists and experts are tackling the most pressing challenges to achieve real-world impact. This Earth Day, join us in our commitment to realizing a just and sustainable future for our planet. Visit our Earth Day website for ideas, resources, and inspiration.
