Arctic Warming, Extreme Weather Link Far From Certain

Arctic Warming, Extreme Weather Link Far From Certain

The polar vortex that brought frigid weather and snow to much of the U.S. in early January, returned later in the month, and is on the way back for a third time, had plausible links to global warming—according to some scientists, anyway. The idea is that rapid climate change in the Arctic has disrupted the jet stream, leading to spates of extreme… Read More

Watch 27 Years of ‘Old’ Arctic Ice Melt Away in Seconds

Watch 27 Years of ‘Old’ Arctic Ice Melt Away in Seconds

The total amount of Arctic sea ice is near record low for this time of year. The amount of ice isn’t the only big story, though. A video from the National Oceanic and Atmospheric Administration shows a disturbing trend in the age of Arctic ice. Since 1988, Arctic sea ice is getting younger, and young ice is not a good thing. In 1988, ice that was … Read More

Arctic Sea Ice Sits at Record Low for Mid-February

Arctic Sea Ice Sits at Record Low for Mid-February

Arctic sea ice growth has slowed dramatically in recent weeks, thanks in large part to abnormally warm air and water temperatures. Sea ice now sits at record low levels for mid-February. According to the National Snow and Ice Data Center, as of February 18, sea ice covered about 14.36 million square miles in the Arctic. The previous low on this da… Read More

Greenland’s Fastest-Flowing Glacier Speeds Up

Greenland’s Fastest-Flowing Glacier Speeds Up

A fast-moving Arctic glacier which has earned a place in history is now accelerating even more quickly. The Jakobshavn Isbrae (the Danish word for glacier) is a massive river of ice from the Greenland ice sheet to an Atlantic Ocean fjord and is thought – there is no way of proving this – to be the source of the giant iceberg that sank the Titanic … Read More

Melting Sea Ice Makes Arctic Drilling a Risky Business

Melting Sea Ice Makes Arctic Drilling a Risky Business

Melting Arctic sea ice could open previously dangerous waters to expanded oil drilling, but the risks and expense of doing so could still be extreme, a new paper says. Government regulators and environmentalists have been forceful with their concern about the hazards of drilling in the Arctic, saying that the costs of cleaning up an oil spill in ic… Read More

Polar Vortex Is Back: Coldest of the Cold En Route to U.S.

Polar Vortex Is Back: Coldest of the Cold En Route to U.S.

Of course, blaming this all on the polar vortex isn’t entirely accurate. The true polar vortex exists at upper levels of the atmosphere, and what’s been causing January’s bitter cold - and soon to be February’s - is a result of the interaction between the vortex and events in the more chaotic lower atmosphere. The polar vortex exists at the upper … Read More

Climate Change Brings New Risks to Greenland

Climate Change Brings New Risks to Greenland

When the world's miners, oil-workers, construction teams and industrialists descend on Greenland over the next few years to dig below the rapidly retreating icecap for its ores, hydrocrabons and minerals, no one will watch with more concern – or confidence – than Prime Minister Aleqa Hammond. The Inuit leader of a country with just 56,000 people w… Read More
