Massive Iceberg Snaps Off Greenland--But What Does It Mean?
August 10, 2010

Yesterday, a massive ice island four times the size of Manhattan snapped off of Greenland's Petermann Glacier. Ominous, no? A disturbing sign of a warming planet? Well… actually, it's hard to say. It's true that, in a broad sense, Greenland has been losing ice faster than it has been accumulating snow in recent years. The thing's clearly melting. But linking this one specific glacier calving to global warming is more difficult, and something many glaciologists are reluctant to do.

Why The IPCC Needs Fixing
January 31, 2010

Over at Dot Earth, Andy Revkin has a smart story about the growing pressure to change how the Intergovernmental Panel on Climate Change (IPCC) operates, especially after the recent scandal over glaciers.

Are We Ready For The Rising Seas?
January 14, 2010

One aspect of climate change that's already affecting people in various parts of the world is the slow but steady rise in sea level (via YaleE360): Pacific and Indian Ocean atoll nations are already being abandoned because of the direct and indirect effects of sea level rise, such as saltwater intrusion into groundwater. In the Marshall Islands, some crops are being grown in abandoned 55-gallon oil drums because the ground is now too salty for planting. New Zealand is accepting, on a gradual basis, all of the inhabitants of the Tuvalu atolls.

Greenland Dispatch: Europe's Last Colony And The Big Melt
November 14, 2008

Alexander Zaitchik is a freelance journalist based in New York City. He visited Greenland in August as part of an official press delegation sponsored by the island's home-rule government. It's become a cliché of Arctic reportage to begin stories by describing the calving of glaciers—that process by which enormous vertical slabs of ice, some as tall as skyscrapers, slice off the glacial shelf and collapse into the waiting sea. During a recent reporting trip to Greenland, I quickly understood the impulse to chronicle this phenomenon.

The Shot Heard Round The World
July 18, 1988

"Here once the embattled farmers stood And fired the shot heard round the world."  —Hymn sung at the completion of the Battle Monument, Concord, July 4, 1837   The claim in Emerson's line is expansive. Can it be true that the shot was heard round the world—when there were no satellites, no television, no radio, no telephone? Let us see. It then took from five to six weeks for news to cross the Atlantic.
