There is no perfect parallel in Earth’s past for present-day climate change—human-driven warming is simply happening too fast and furiously. The closest analog came 56 million years ago, when over the course of 3000 to 5000 years, greenhouse gases soared in the atmosphere, causing at least 5°C of warming and…

Paul Souders/Getty Images “Save the polar bears” has long been a mantra among the climate-conscious. But a new study has suggested that the Arctic mammals might not need our help quite as much as we once thought. A team of researchers has discovered a unique population of polar bears who…

An adult female polar bear, left, and two 1-year-old cubs walk over snow-covered freshwater glacier ice in Southeast Greenland in March 2015. With limited sea ice, these Southeast Greenland polar bears use freshwater icebergs spawned from the shrinking Greenland ice sheet as makeshift hunting grounds, according to a study in…

Last August, rain fell for the first time at the peak of Greenland’s ice sheet, but this had little impact on ice melt compared with other effects Environment 17 June 2022 By Adam Vaughan A weather station on the Greenland ice sheet GEUS/ESA When rain fell for the first time…

Sea ice provides a hunting platform for polar bears all around the Arctic. Polar bears are rushing to find ice to hunt on as the world heats due to human-caused climate change and Arctic sea ice disappears. But a new study reported the discovery of an isolated population of polar…

A newly discovered subpopulation of polar bears in remote southeastern Greenland have found a way to eke out a living under warm conditions similar to those forecasted for much of the Arctic later this century, scientists reported on June 16 in Science. Warming temperatures are causing sea ice, which polar…
