Last Ice Area Expedition Launches

Climate projections forecast the total disappearance of summer sea ice in the Arctic by 2040, with the exception of one place: the “last ice area,” north of Greenland and Ellesmere Island in Nunavut. This area will likely harbor the largest concentration of Arctic wildlife that depends on the sea ice edge for survival, including bowhead…

Your plastic is getting to the Caribbean more often than you are, and it’s spoiling your next visit

Who left their trash behind on this remote Caribbean island? Then I realized. It wasn’t left. It arrived. An endless flotilla of refuse heedlessly sent from afar. It’s heartbreaking. The image of a lone bottle washing up on a remote tropical island is the clichéd stuff of literature, movies and New Yorker cartoons. But what…

On Wildlife Conservation Day, Protect Climate Refuges to Help Corals

By Emily Darling

Protected areas are a hallmark strategy in marine conservation. Yet when they were first created, a growing lethal threat had not yet fully revealed itself. Warming, acidifying, and rising seas have devastated the world’s sensitive coral reefs, widely regarded as “ground zero” for climate change. El Niños and marine heat waves can bleach and destroy vast areas of healthy, biodiverse reefs even where they occur within “protected” parks. If the global impacts of climate change do not stop at park boundaries, what can scientists do? One strategy is to identify and protect climate refuges – habitats with more stable environments where species can survive warming temperatures.
