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

Giant Icebergs Have Surprise Role in Slowing Warming

Giant Icebergs Have Surprise Role in Slowing Warming

The biggest icebergs breaking off Antarctica unexpectedly help to slow global warming as they melt away into the chill Southern Ocean, scientists said on Monday. The rare Manhattan-sized icebergs, which may become more frequent in coming decades because of climate change, release a vast trail of iron and other nutrients that act as fertilisers for… Read More

2016: What to Look for in Energy and Climate

2016: What to Look for in Energy and Climate

2016 will kick off with a sense of optimism about climate change after the success of the Paris climate talks in December. In the U.S., that may mean more enthusiasm for commitments to renewables and other lower-carbon energy sources as low oil prices make the future of fossil fuels production in the U.S. and Canada less certain.… Read More
