The Arctic may no longer be the refuge it once was for migrating animals. Scientists now fear that climate change and environmental degradation have turned the yearly journey of numerous species, including birds, butterflies and ungulates, into an ecological trap. Upon reaching their destination, many animals are likely starving, being hunted or dying of disease

Even if humanity beats the odds and caps global warming at 1.5 degrees Celsius above preindustrial levels, seas will rise for centuries to come and swamp cities currently home to half-a-billion people, researchers warned Tuesday. In a world that heats up another half-degree above that benchmark, an additional 200 million of today’s urban dwellers would

Animal farming accounts for twice as many greenhouse gas emissions as plants grown for consumption, according to a study published Monday that mapped agricultural activities worldwide. What humans eat accounts for a major chunk of the emissions behind climate-change – transportation, deforestation, cold-storage. and the digestive systems of cattle all send polluting gases into the

Exposure to a cocktail of agrochemicals significantly increases bee mortality, according to research Wednesday that said regulators may be underestimating the dangers of pesticides in combination. Bees and other pollinators are crucial for crops and wild habitats and evidence of steep drops in insect populations worldwide has prompted fears of dire consequences for food security

Greenland’s ice sheet has experienced a “massive melting event” during a heatwave that has seen temperatures more than 10 degrees Celsius above seasonal norms, according to Danish researchers. Since Wednesday the ice sheet covering the vast Arctic territory, has melted by around 8 billion metric tons a day, twice its normal average rate during summer,

Abrupt disruptions to Earth’s climate thousands of years ago that caused extreme sea-level rise and mass ice cap melting can serve as an early warning system for today’s planetary tipping points, according to new research.  Climate tipping points – which are irrevocable over centuries or longer – are thresholds past which large and rapid changes

The Bootleg Fire that has scorched more than 1,500 square km (600 square miles) in Oregon is so big it can be seen from space. Videos shared by the National Oceanic and Atmospheric Administration earlier this week show smoke plumes rising into the air from the Bootleg Fire. The fire has burned over 360,000 acres, officials said. UPDATE: @NOAA‘s #GOES17🛰️ continues

Climate change and deforestation have flipped a large swathe of the Amazon basin from absorbing to emitting planet-warming carbon dioxide (CO2), a transformation that could turn humanity’s greatest natural ally in the fight against global warming into a foe, researchers reported on Wednesday. ​Hundreds of high-altitude air samples collected over the last decade showed that
