A landslide last October detected in Alaska by Lamont's Colin Stark and Göran Ekström might be the biggest non-volcanic landslide recorded in North American history. It also created a wave that sheared alders more than 500 feet up the opposite hillside.
Global warming will require big changes in how we management water, the Desert Sun writes. “In general, what a measure like this is telling us is that our historical reliance on snow is untenable in a future climate," said Lamont's Justin Mankin.
The vast Greenland ice sheet is seeing a record-breaking level of melt for so early in the season. “The potential implications, in terms of runoff and so on, they alter the memory of the snowpack, the potential implications can be big either for the same season or future seasons,” said Lamont's Marco Tedesco.
The World Surf League just launched a non-profit, WSL PURE. It will help researchers at Columbia University's Lamont-Doherty Earth Observatory study climate change and the ocean.
If climate change continues, we can expect a large rise in sea level this century, and it will only get worse in the centuries to come. The BBC talks with Lamont's Maureen Raymo.
