US President Donald Trump’s administration on Thursday removed endangered species protections for the gray wolf, paving the way for the iconic predator to be more widely hunted.   The move was slammed by conservation groups, which said that while wolf numbers have partly recovered since the animal was first listed in 1974, they remain “functionally

Rapid melt is reshaping coastal Greenland, potentially altering the human and animal ecosystems along the country’s coast.  New research published in the Journal of Geophysical Research: Earth Surface on Oct. 27 finds that the ice retreat in Greenland has changed the way glaciers flow and where they dump into the sea. These changes could impact ice loss from

Agricultural department workers wearing protective suits have eradicated the first nest of giant “murder hornets” discovered in the United States, vacuuming them out of a tree in Washington state.   The nest of Asian giant hornets was found on Thursday by Washington State Department of Agriculture (WSDA) entomologists on a property in Blaine, near the

Scientists think they’ve finally come closer to identifying the cause of Earth’s worst mass extinction, by tracking down the geochemical trigger that may have started it all. Known as the Great Dying, the Permian-Triassic extinction event happened around 252 million years ago. The new research is based on a study of fossil shells left behind by clam-like

The group climbed the steep mountainside, clambering across an Alpine glacier, before finding what they were seeking: A crystal vein filled with the precious rocks needed to sculpt their tools.   That is what archaeologists have deduced after the discovery of traces of an ancient hunt for crystals by hunters and gatherers in the Mesolithic

The ice-covered Grímsvötn volcano on Iceland produced an unusually large and powerful eruption in 2011, sending ash 20 kilometres into the atmosphere, causing the cancellation of about 900 passenger flights. In comparison, the much smaller 2010 eruption of Eyjafjallajökull led to the cancellation of about 100,000 flights.   Understandably, any mention of another explosive eruption

Global warming is making the oceans more stable, increasing surface temperatures and reducing the carbon they can absorb, according to research published Monday by climate scientists who warned that the findings have “profound and troubling” implications.   Man-made climate change has increased surface temperatures across the planet, leading to atmospheric instability and amplifying extreme weather

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,

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

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
