Trees that grow quickly die younger, risking a release of carbon dioxide that challenges forecasts that forests will continue to be a “sink” for planet-warming emissions, scientists said Tuesday. Tree cover absorbs a significant proportion of carbon dioxide emitted by burning fossil fuels and plays a crucial role in projections for our ability to wrestle

“Zombie” wildfires that were smoldering beneath the Arctic ice all winter suddenly flared to life this summer when the snow and ice above it melted, new monitoring data reveal. And this year has been the worst for Arctic wildfires on record, since reliable monitoring began 17 years ago. Arctic fires this summer released as much carbon in the first

There is no doubt that Australia’s Black Summer last year was absolutely devastating. Fires across the country burnt through 186,000 square kilometres (72,000 square miles) of land, killing 34 people, while billions of animals were affected.   But there’s something particularly chilling about seeing the end results of the blaze. Australian aerial analysis company Geospatial Intelligence

The Greenland and Antarctic ice sheets, which hold enough frozen water to lift oceans 65 metres, are tracking the UN’s worst-case scenarios for sea level rise, researchers said Monday, highlighting flaws in current climate change models. Mass loss from 2007 to 2017 due to melt-water and crumbling ice aligned almost perfectly with the Intergovernmental Panel

Songbirds in tropical rainforests curtail their reproduction to help them survive droughts, according to a study Monday. Species with longer lifespans were better able to cope with this environmental volatility than previously thought, researchers found. With more record hot spells gripping parts of the planet and biodiversity threatened by human encroachment on habitats, a crucial

Scientists from Leeds and Edinburgh universities and University College London analysed satellite surveys of glaciers, mountains, and ice sheets between 1994 and 2017 to identify the impact of global warming. Their review paper was published in the journal Cryosphere Discussions. Describing the ice loss as “staggering,” the group found that melting glaciers and ice sheets could cause

Satellite images of penguin poop in Antarctica have revealed a number of Emperor penguin colonies living and breeding on the icy continent that scientists weren’t previously aware of. Eight completely new communities have now been found in some of the most remote and inaccessible parts of Antarctica, and three additional colonies that were previously identified

Tropical Storm Isaias was set to regain hurricane strength Monday before slamming into the US eastern seaboard, bringing life-threatening storm surges to North and South Carolina. The storm, currently 60 miles (100 kilometers) southeast of Charleston, South Carolina, was packing sustained winds of 70 miles (112 kilometers) per hour, with wind speeds predicted to increase

Common chemicals nicknamed ‘forever chemicals‘ for their tendency to stick around in the environment for a disconcertingly long time have been detected in Arctic seawater. PFAS (per and polyfluoroalkyl substances) chemicals are used in a lot of household products. While the effects of PFAS on human health are still being debated, they have been detected in

Norway’s Arctic archipelago Svalbard on Saturday recorded its highest-ever temperature, the country’s meteorological institute reported. According to scientific study, global warming in the Arctic is happening twice as fast as for the rest of the planet. For the second day in a row, the archipelago registered 21.2 degrees Celsius (70.2 Fahrenheit) in the afternoon, just

As plants begin to spread across melting permafrost, scientists are growing ever more worried their roots will stir microbes into unleashing vast stores of carbon. To scientists, roots are known as rhizomes, and when these tendrils extend deeper into the soil, it accelerates microbial decomposition by up to fourfold, potentially ‘priming’ the frozen ground for

Scientists have, for the first time, discovered an active leak of methane gas from the sea floor in Antarctica. It is a process that’s likely to accelerate the process of global heating. The finding was published in the peer-reviewed Proceedings of the Royal Society B scientific journal on Tuesday. Methane is powerful greenhouse gas that accelerates climate

We might have a problem with our roads: researchers have discovered that sunlight and rain might be able to turn certain compounds in asphalt into a potentially dangerous hydrocarbons, threating the surrounding environment and people using these routes. In particular, it’s the binder (also called asphalt cement) that’s the problem. This heavy, black glue is
