Bumblebees are dying across North America and Europe as the climate warms, scientists say

Bumblebee populations in North America and Europe have plummeted as a result of extreme temperatures, according to a study published Thursday in the journal Science. © Ulrich Perrey/picture-alliance/dpa/AP A bumblebee flies in search of nectar over a flowering basil plant. The number of areas populated by bumblebees has fallen 46 percent in North America and…

Global warming is speeding up Earth’s massive ocean currents

A warming climate appears to be altering global currents, reconstructed here from satellite and ship readings. NASA/GODDARD SPACE FLIGHT CENTER SCIENTIFIC VISUALIZATION STUDIO By Paul VoosenFeb. 5, 2020 , 2:00 PM The oceans’ great continent-wrapping currents, each one moving as much water as all the world’s rivers combined, can rightly be considered the planet’s circulatory…

‘Abrupt thawing’ in the Arctic could increase the carbon released from permafrost by 50 per cent

Abrupt thawing in the Arctic could increase the amount of carbon released into the atmosphere from permafrost by 50 per cent, scientists warn.Experts have long feared that climate change — which is heating the Arctic and subarctic at double the global rate — will unleash long-trapped greenhouse gases. Both methane and carbon dioxide that could add…

Global heating a serious threat to the world’s climate refuges, study finds

Biodiversity hotspots that have given species a safe haven from changing climates for millions of years will come under threat from human-driven global heating, a new study has found. Species that have evolved in tropical regions such Australia’s wet tropics, the Guinean forests of Western Africa and the Andes Mountains will come under increasing stress…

Scientists find another threat to Greenland’s glaciers lurking beneath the ice

(CNN)Scientists have long known that higher air temperatures are contributing to the surface melting on Greenland’s ice sheet.But a new study has found another threat that has begun attacking the ice from below: Warm ocean water moving underneath the vast glaciers is causing them to melt even more quickly.The findings were published Monday in the…
