Tackling an Ice Age Mystery
In a new study in Nature, climate scientist Maureen Raymo and her colleagues show that variations in sunlight interact with Earth’s topography and the size of ice sheets to control Earth’s ice ages on 100,000 year cycles. One important finding: as ice sheets grow bigger, they also become more vulnerable to melting.

400 ppm World, Part 2: Rising Seas Come with Rising CO2
Every indication is that thermal expansion will not dominate rates of sea-level rise in the future. 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.

The Law of Drowning Nations
Sea levels are inching up year by year, and by various projections could be two to six feet higher by 2100—enough to make some small, low-lying island nations uninhabitable, or simply to wipe them off the map. What rights will citizens have to live elsewhere; in fact, will these entities actually still be nations, with…

A New Primer on Sea Level
The threat of sea-level rise–actually, its ongoing reality–has been on many more minds since New York and surrounding areas were walloped during Hurricane Sandy by a record-high storm surge, abetted by a water level that has risen steadily over the last century. That level will keep rising if climate keeps warming, and so, probably, will…

The Impact of Sea Level Rise on Coastal Wetlands
An analysis of coastal wetlands loss from sea level rise that was conducted for the Ramsar Convention’s Scientific and Technical Review Panel provides estimates of wetland losses as a basis for identifying potential adaptation measures.

The Science and the Lessons of Hurricane Sandy
Reports and studies have been imagining events like Sandy for years now; so why were so few people ready to listen? And will this lead to a serious conversation about climate change in the halls of power?

Watch an Antarctic Iceberg in the Making
What does a glacier about to spawn an iceberg the size of New York City look like? A new animation from NASA flies you through the 19-mile crack that is slowly tearing Antarctica’s Pine Island Glacier apart.

Climate Scientist Studies Ancient Shorelines
The seas are rising, as they have during past periods of warming in earth’s history. Estimates of how high they will go in the next few thousand years range from five meters, putting greater Miami underwater, to 40 meters, wiping most of Florida off the map. “The range of estimates is huge to the point…

Leaders of Distinction: The Lamont Research Professor
Robin Bell will soon become one of the most senior Observatory researchers to receive the title of Lamont Research Professor, which elevates the status of Lamont’s distinguished researchers to something akin to tenure in the University setting, and which will support Lamont’s recruitment efforts of such dedicated educator/researchers well into the future.
