West Antarctica’s glaciers are the weakest link in the icy armor that surrounds the massive southern ice sheet. A study published in the Annals of Glaciology last month adds to the pile of crap news about how these glaciers, which extend out over water that’s being warmed by climate change, are susceptible to melting…
Every year, NASA’s Operation Icebridge plumbs the wonders and woes of the ice at both poles, and 2017 is no different. Icebridge’s Antarctic field mission kicked off about a month ago, and satellites and planes are hard at work monitoring glaciers, ice sheets, and sea ice.
Nearly all the ice on Earth is in some state of meltdown. As it spills into the ocean, it raises sea levels. But if you’re curious to know exactly which glaciers are going to drown your corner of the planet, NASA’s got some answers.
The Greenland ice sheet is getting darker, and that’s bad news for the Arctic thermostat, since darker surfaces absorb more heat. Now, a pair of scientists have concluded that in at least one section of Greenland, tiny algae play an outsized role in giving the ice its surprising shade.
It’s well known that Greenland contains a ton of frozen water—enough to raise sea levels by nearly 25 feet were it all to melt. Unfortunately, new research suggests melting may occur faster than we thought as the Earth warms, because of how Greenland’s glaciers are anchored to bedrock.
The Earth contains hints about its past everywhere. And as we hurtle toward a much warmer future, those clues can tell us a lot about what we face.
Satellites have changed how we see the world. That includes being able to watch climate change overrun everything beautiful in agonizing detail.
Climate change and ice, they do not mix. I know it. You know it.
When a trillion ton iceberg snapped off the Antarctic Peninsula’s Larsen C ice shelf in July, the entire world spent a few days geeking out over stunning satellite imagery of Earth’s frozen continent. But those who’ve stuck with the Delaware-sized iceberg, now called A68, on its slow journey into the Weddell Sea, know…
