For more than 10 years, adjunct researcher Daniel Ruiz Carrascal from the International Research Institute for Climate and Society has been studying Colombia’s páramos. This unique mountaintop ecosystem is important in terms of biodiversity and water supply, but is particularly threatened by climate change; the páramos are warming nearly as fast as the Arctic, and… read more

From November 2018 to February 2019, our team is studying how rocks alter and erode in one of the most extreme environments on the planet—Antarctica. The project is called Landscape evolution in the McMurdo Dry Valleys: Erosion rates and real-time monitoring of rock breakdown in a hyperarid, subzero environment, and it is funded by the… read more
Tools of the Trade is a new series that brings you inside the labs of Earth Institute scientists. Learn about the equipment scientists are using, and discover how those tools are used in their research.
What if the warming Arctic climate were to result in more snow? Could decreasing sea ice cover actually drive more evaporation of newly exposed Arctic ocean water into the atmosphere? And could that increased moisture in the air fall on the ice sheet as snow? If yes, will this stabilize the Greenland Ice Sheet, stopping… read more
Biological oceanographer Sonya Dyhrman’s team is embarking on a research cruise off Hawaii as part of the Simons Collaboration on Ocean Processes and Ecology (SCOPE) on the R/V Kilo Moana. Gwenn Hennon and Matthew Harke will be at sea for nearly three weeks with logistical support from Sheean Haley back on shore. The cruise will be… read more
Learn more about the 2015 Paris climate agreement, the science behind climate change, and what the Trump administration’s decision to pull out of the agreement means for the future.
Bridgit Boulahanis, a graduate student at Lamont-Doherty Earth Observatory, joined a team of 18 scientists from across the United States on an expedition to the eastern Pacific Ocean. Their mission: to investigate a chain of submarine volcanoes, or seamounts, along the East Pacific Rise. The OASIS (Off Axis Seamounts Investigation at Siqueros) team will be… read more
Lamont’s polar scientists are back in Antarctica on missions to study the continent’s ice. Ice shelves like the Ross Ice Shelf reach out over the ocean from the massive ice sheet covering the continent, and researchers are exploring how changes in climate will affect them. Flying over the ice and using remote sensing equipment, they… read more
Bridgit Boulahanis, a marine geophysics graduate student at Columbia University’s Lamont-Doherty Earth Observatory, joins a team of early career scientists on their way to becoming chief scientists in a training cruise focused on seafloor exploration. They’ll be getting their first experiences working with submersibles as they dive into projects ranging from cephalopod collection to acoustic… read more
Students from Columbia University and Tel Aviv University travel to Jordan and Israel to learn about how the two countries are cooperating on environmental issues and managing shared natural resources. The trip is part of a course on regional environmental sustainability in the Middle East, a collaboration between Columbia University’s Earth Institute and School of… read more
