The solitude of the north is changing. George Angohiatok noticed this quite graphically a decade ago when, after returning to Iqaluktuuttiaq (or Cambridge Bay, as it was renamed by settlers), he observed…
The Arctic is setting records for low sea ice extent for this time of year, with the 2020 refreeze now 500,000+ square kilometers behind a record set in 2019 — a sign the region may be entering a new climate regime.
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.
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.
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.
1. Climate change and oceans Climate change impacts on land made almost daily headlines this year: fires, floods, more extreme storms. Equally intense effects are being realized in our seas.…
For seabirds, an Arctic Ocean with less sea ice could provide some tantalizing alternatives to the long-haul flights that some undertake each year. In a recent study, ecologist Manon Clairbaux…
New report reveals how both the Arctic and Antarctic are heating up and changing dramatically amid ongoing, but largely insufficient, UN climate negotiations.
Climate change could be carving a path for dangerous diseases through the Arctic, allowing them to spread between species of susceptible marine mammals, according to a recent study. Researchers have…
If the climate continues to change at its current pace, most emperor penguins could become extinct by the end of this century, a new study predicts. However, if countries meet…
As a massive expanse of unusually warm water spreads across the northeastern Pacific Ocean for the second time in the past five years, the latest special report from the Intergovernmental…
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.
In a press conference yesterday, UN secretary general António Guterres announced that July 2019 was the hottest month on record. Data for the month is still being collected, but July…
June 2019 was the hottest June recorded in the 140 years since the US National Oceanic and Atmospheric Administration (NOAA) began collecting global temperature data, the agency announced yesterday. Global…
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.
For decades, sea ice in Antarctica has increased while that in the Arctic has declined drastically. But in a puzzling turn of events, Antarctic sea ice has been decreasing rapidly…
Until recently, researchers knew of four lakes lying hidden underneath the Greenland ice sheet. Now, scientists say they’ve identified 56 more, bringing the total to 60 known subglacial lakes beneath…
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.
Antarctica’s second-largest colony of emperor penguins has likely not produced any chicks over the last three years, a new study has found. Until recently, the emperor penguin colony at Halley…
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.
Antarctica is losing ice at a rate that’s about six times faster than in the late 1970s, and that’s pushed up the global sea level by around 14 millimeters (0.55…
1. The race is on to map the seafloor Is it true that we have explored the moon and Mars more thoroughly than the bottom of the ocean? Embarrassingly, yes.…
Dead whales are a nutritional boon for polar bears, and they’ve likely helped bears survive lean periods during warm spells in the past when much of the Arctic was ice-free.…
With the Arctic’s melting ice cover leaving the ocean ice-free for longer periods of time, new shipping routes are opening up, paving the way for future commercial activities. But under…
For 19th-century adventurers like Sir John Franklin, navigating a path through the ice-choked Northwest Passage — the Holy Grail of Arctic exploration — was a treacherous and often deadly undertaking.…
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…
KUCHING, Malaysia — Conservationists have called on governments and the private sector to do more to mitigate the impact of global shipping activities on marine ecosystems and communities in the…
