Medical, public health, and conservation experts are calling for greater pathogen surveillance and regulation of the legal wildlife trade in order to quickly identify pathogens and prevent the next pandemic.
Though September sea ice extent appeared to offer a short-term recovery this fall, “that’s not the full story,” says one Arctic scientist, with low ice concentration seen in 2021, and lack of multiyear ice setting a new record.
For more than a year, the world has closely followed the development, approval and deployment of various coronavirus vaccines that could bring an end to the global pandemic, debating every…
Sea ice fell to its lowest extent on record for this time of year, while new studies find Arctic coastal ice may be receding 70-110% faster than thought, winter ice is failing to regrow fully, and last multi-year ice refuge is under assault.
Polar phytoplankton, fish, seabirds and mammals are increasingly threatened by global warming, which is destabilizing Arctic ecosystems, even as southern species move northward — will the imbalanced biome collapse?
New research finds that ice in both polar regions, and especially sea ice, is disappearing at a quickening rate, while in the Arctic the last stronghold of multiyear ice is under assault from warming.
Upon reaching 2 degrees Celsius of warming, the West Antarctic Ice Sheet won’t regrow until temperatures are at least 1 degree cooler than they were before the Industrial Revolution, say scientists.
2020 didn’t eclipse all-time record-holder 2012, but it came pretty close; also, the Arctic’s growing heat is likely intensifying Asia’s extreme weather, while waters just beneath the ice are getting increasingly warm.
Meet biologist Jonathan Slaght as he spends years tracking a giant bird “the size of a fire hydrant with a six-foot wingspan.” Slaght’s new book, Owls of the Eastern Ice, offers engaging tales from the field.
Temps as high as 100 degrees Fahrenheit in Siberia have triggered record Arctic sea ice melt, raging wildfires, permafrost thaw, and an Arctic oil spill.
April and May saw record intense Arctic heat. Now some scientists are asking whether an absence of industrial sulfate aerosol pollutants, which reflect solar energy, could be the cause.
Multiple studies show that Arctic warming is altering temperate and equatorial weather. Now, new research finds that Antarctic ice melt could be a major tropical change agent too.
Scientists are already warning of gradual permafrost CO2 releases; but future abrupt thaws could send huge amounts of methane skyward, causing a surge in global temperatures.
New research offers early evidence that the Arctic and tropics are no longer a world apart; melting sea ice may be intensifying equatorial trade winds and emergence of El Niño.
New report reveals how both the Arctic and Antarctic are heating up and changing dramatically amid ongoing, but largely insufficient, UN climate negotiations.
As 2019 melt season nears end, 40 years of satellite data reveal a rapidly warming polar region, with no end in sight, plus multiple impacts for a changing planet. This story has been updated.
High heat and conditioning throughout this year’s melt season put a hurting on Arctic sea ice, but it may still take big storms or more heat to break 2012 extent record.
A very hot Arctic spring has caused sea ice volume to fall rapidly to a new record, putting 2019 in position to challenge 2012 for lowest ice volume and extent this September.
Though the trend can still change, Arctic sea ice extent could be on track for a record melt year, impacting the jet stream and bringing more extreme weather to the U.S. and world.
Sea ice melt is nearly two weeks ahead of past records for early April, while a new study finds that the Arctic system is trending away from its 20th century state into an unprecedented state.
Though sea ice extent was up across much of the Arctic at winter maximum, the Bering Sea lost an ice area the size of Montana, and Greenland has been receiving winter rains.
Ivory, pangolin scales, bear bile: Rachel Nuwer, author of the new book “Poached,” saw it all as she trekked from rainforests to posh restaurants on the trail of wildlife traffickers.
Biologist Joel Berger endures extreme conditions to study muskoxen and learn about the opportunities — and limits — of behavioral flexibility in a fast changing climate.
At the start of August, for the second time this year, a corridor of open water developed along the north shore of Greenland, this one more than 100 kilometers (over…
In a counterintuitive surprise, a new study finds that fish species evolve more than twice as rapidly at the poles than in the tropics. The reason why isn’t currently known.
A very mild May over the Arctic Ocean could be setting us up for record ice loss at the September minimum; a giant cyclone and high temps in June escalated the melt.
With the Arctic winter of 2017-18 the warmest on record, researchers are finding a troubling range of climate change impacts on wildlife, including wolverines, reindeer, snowy owls, and more.
A new study finds that more frequent Arctic extreme weather, such as rain-on-snow events, result in smaller head size and possibly lower survival rates in muskox young.
Summer sea ice didn’t reach its lowest extent on record in 2017, but that’s not the only measurement that matters, experts warn.
Study: rapidly warming Arctic reduces food supply and stored energy for shorebird, weakening juveniles on long migratory trips, reducing size, survival chances.
