The frozen state of permafrost enables it to store large amounts of carbon; about […]

Emily Osborne, a marine scientist with NOAA’s Ocean Acidification Program, examines a sediment sample taken from the Santa Barbara Basin off California which contains recently deposited microscopic foraminifera shells.

The Arctic region is heating up faster than any other place on Earth, and as more and more sea ice is lost every year, we are already feeling the impacts. IIASAresearchers explored strategies for cooling down the oceans in a world without this important cooling mechanism. Scientists estimate that summer sea […]

Global satellite imagery shows transitions occur quickly after blocks of forest are cut in half. University of Cincinnati geography researchers have identified a tipping point for deforestation that leads to rapid forest loss. Geography professor Tomasz Stepinski used high-resolution satellite images from the European Space Agency to study landscapes in […]

Between 2005 and 2016, the shift away from coal saved an estimated 26,610 lives and 570 million bushels of crops. The decommissioning of coal-fired power plants in the continental United States has reduced nearby pollution and its negative impacts on human health and crop yields, according to a new University […]

Over the last decade, several high-profile […]

North American surface temperatures for Dec. 26, 2017-Jan. 2, 2018: even if it is extremely cold in a region, this does not mean that climate change has stopped.
