In a new study, researchers show how widely wind and solar potential vary by season and year, suggesting that backup energy sources may be needed as the world shifts to renewables to bring carbon emissions to zero.

A new venture will leverage big data and many disciplines to create better estimates of future climate.

In a new study, researchers report that their physics-based model of California earthquake hazards replicated estimates from the state’s leading statistical model.

A new algorithm quickly sifts through hours of field recordings to learn how climate change influences bird migration. The A.I. could help track other wildlife as well.

In a new study, researchers show that machine learning algorithms can pick out different types of earthquakes from three years of data at Geysers in California. The repeating patterns of earthquakes appear to match the seasonal rise and fall of water-injection flows into the hot rocks below.

Researchers report a sharp drop in salinity in the North Atlantic Ocean over the last decade, providing the most detailed look yet at the region’s changing ocean conditions. A continued decline could impact fish stocks and the ocean’s ability to absorb CO2.

Adding protective barriers around street trees could reduce load on city sewers, study finds.

If carbon emissions hold steady, a new study in Science predicts that the European Union could face a massive influx by 2100.

A warming climate is not just melting the Arctic’s sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country’s waters, says a new study.

Kartik Chandran, an environmental engineer at Columbia, will discuss some of his urban wastewater treatment projects at a panel discussion Friday following the screening of a new film about Rio de Janeiro’s Guanabara Bay.
