Sea Ice News

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.

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.

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…
