Scientists have known for some time that ice shelves off West Antarctica are melting as deep, warm ocean waters eat at their undersides, but a new study shows that temperatures, and resultant melting, can vary far more than previously thought, within a time scale of a few years.

The American Geophysical Union honors the outstanding work of three scientists from Columbia’s Lamont-Doherty Earth Observatory.
We awoke to messages that a towering iceberg is threatening the local waterfront settlement of Innaarsuit. There is perhaps a bit of irony in the fact that a massive looming block of ice is a potential threat to the start of our field season.
Snow on Ice is launching into the field with two teams of scientists this summer. The first group, an ‘advance team’ of six women, will focus on lakes where meltwater has collected on the southwestern flank of Greenland bedrock.
Scientists have long determined what extinct animals ate by analyzing carbon isotopes locked inside their fossil teeth. But a new study shows that in many cases, they may be plugging the wrong numbers into their equations. The findings may change some views of how mammals, including us, evolved.
Three decades after Hansen first warned Congress about global warming, the overwhelming scientific consensus is that he was right—and most would say that far too little has been done to address the threat.

A new model estimates how many climate migrants there will be, where they are likely to go, and what effects they might have on the places to which they move.
For anyone who has ever wished there were more hours in the day, geoscientists have some good news: Days on Earth are getting longer. Very slowly.
Intensifying river floods caused by global warming may hamper national economies worldwide, and effects might propagate through global trade and supply networks, a new study says.
