Wildfires are burning the West Coast, hurricanes are flooding the Southeast — and some of those storms are rising from the dead.  “Zombie storms”, which regain strength after initially petering out, are the newest addition to the year 2020. And these undead weather anomalies are becoming more common thanks to climate change. “Because 2020, we

Raising Earth’s average surface temperature another degree Celsius will lock in 2.5 metres of sea level rise from Antarctica alone and an extra three degrees see the frozen continent lift oceans 6.5 metres, scientists warned Wednesday. These devastating increases in the global waterline – enough to cripple coastal cities from Mumbai to Miami and displace

The world’s most advanced telescopes were not made for today’s temperatures, and it’s messing with our observations of the night sky.  Three decades-worth of data from the Paranal Observatory in northern Chile – home of the European Southern Observatory’s Very Large Telescope (VLT) – has revealed several ways in which climate change is already impacting

A massive chunk of ice – larger than the city of Paris – has broken off from the Arctic’s largest ice shelf because of warmer temperatures in Greenland, scientists said Monday. The 113-square-kilometre (43-square-mile) block broke off the Nioghalvfjerdsfjorden glacier in Northeast Greenland, which the scientists said had been expected given the rising average temperatures.

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
