John Imbrie, a Pioneer of Paleoceanography
Imbrie, a former head of the Department of Geological Sciences, helped confirmed connections between changes in Earth’s orbit and the timing of the ice ages and was a co-founder of CLIMAP, an international effort to use sediment cores to map Earth’s climate at the height of the last ice age.

Iron Fertilization Won’t Work in Equatorial Pacific, Study Suggests
Over the past half-million years, the equatorial Pacific Ocean has seen five spikes in the amount of iron-laden dust blown in from the continents. In theory, those bursts should have turbo-charged the growth of carbon-capturing algae, but a new study shows that the excess iron had little to no effect.

Study Downgrades Groundwater Contribution to Sea Level Rise
Some research suggests that, along with melting ice sheets and glaciers, the water pumped from underground for irrigation and other uses, on the rise worldwide, could contribute substantially to rising sea levels over the next 50 years. A new study published in Nature Climate Change says the magnitude is substantially lower.

In Greenland, Exactly Where Meltwater Enters the Ocean Matters
In southern Greenland in summer, rivers have been streaming off the ice sheet, pouring cold fresh water into the fjords. A new study tracks where that meltwater goes—with surprising results.
By studying thousands of buildings and analyzing their electricity use, Columbia Climate School Dean Alexis Abramson has been able to uncover ways to significantly cut energy consumption and emissions. Watch the Video: “Engineering a Cooler Future Through Smarter Buildings“
