Antarctic Peninsula Has Cooled, but Warming Will Win

Antarctic Peninsula Has Cooled, but Warming Will Win

For most of the latter half of the 20th century, the Antarctic Peninsula was one of the fastest-warming places on the planet, with serious repercussions for the local environment, including the spectacular disintegration of a millennia-old ice shelf, and global sea level rise. But a new study detailed Thursday in the journal Nature suggests … Read More

Oceans Eating Away at Yet Another Part of Antarctica

Oceans Eating Away at Yet Another Part of Antarctica

The Antarctic Peninsula is one of the fastest warming spots on the planet, and it was thought that the rising air temperature was driving the melt of the glaciers along its fringes. But it is actually warm ocean waters that are eating away at the ice along part of its western side, a group of scientists reported Thursday in the journal Science. The… Read More

Antarctic CO2 Hit 400 PPM For First Time in 4 Million Years

Antarctic CO2 Hit 400 PPM For First Time in 4 Million Years

We’re officially living in a new world. Carbon dioxide has been steadily rising since the start of the Industrial Revolution, setting a new high year after year. There’s a notable new entry to the record books. The last station on Earth without a 400 parts per million (ppm) reading has reached it. A little 400 ppm history. Three years ago, the … Read More

Long Overlooked Area of Antarctica Sees Major Ice Loss

Long Overlooked Area of Antarctica Sees Major Ice Loss

Over the past few years, the evidence has piled up that glaciers in parts of Antarctica have been melting and retreating at an increasingly worrying — and potentially unstoppable — pace. Now, new research shows that glaciers in a region of West Antarctica that has received relatively little attention to date have lost a considerable amount of ice.… Read More

Climate Change is Altering How the Poles Drift

Climate Change is Altering How the Poles Drift

The spin of the earth is a constant in our lives. It’s quite literally why night follows day. And while that cycle isn’t going away, climate change is messing with the axis upon which our fair planet spins. Ice melting has caused a drift in polar motion, a somewhat esoteric term that tells scientists a lot about past and future climate and is … Read More

These Ice Cap Images Show the Arctic’s Rapid Change

These Ice Cap Images Show the Arctic’s Rapid Change

This has been a terrible, horrible, no good, very bad week for ice around the world. First came news that Arctic sea ice set a record low extent this winter (topping the old record set last year). Then came news that the West Antarctic ice sheet is facing the threat of runaway melt. Now NASA Earth Observatory has decided to remind us that even … Read More

Scientists Search for ‘Holy Grail’ of Million-Year-Old Ice

Scientists Search for ‘Holy Grail’ of Million-Year-Old Ice

Somewhere deep below the ice in Antarctica lies a time capsule. It’s the holy grail of climate science and promises to reveal the past and future of Earth’s atmosphere. And right now, scientists are meeting in Hobart to work out a plan to dig it up. The time capsule is ice that froze 1.5 million years ago, capturing tiny bubbles of air, bringing … Read More

Weakening Ice Shelves Raise Sea Level Rise Concerns

Weakening Ice Shelves Raise Sea Level Rise Concerns

All along Antarctica’s coast, tongues of floating ice act as a firewall. Any major breaks in the firewall could send inland ice flowing faster to the sea, raising ocean levels and threatening coastal communities around the globe. In some ways, it’s a process already seen in some areas of Antarctica and it’s concerning enough that scientists have … Read More
