Remember the Arctic cyclone that chopped up the Arctic sea ice in 2012, resulting in a new record low summer extent for the satellite era? It turns out they are rather common. From the AGU Fall Meeting and the Ohio … Continue readin...
Thirty years of shrinking Arctic sea ice has boosted extreme summer weather, including heat waves and drought, in the United States and elsewhere, according to a study published Sunday in the journal Nature Climate Change. The new study...Show More Summary
SAN FRANCISCO—From 2000 to 2010, about 1,900 cyclones churned across the top of the world each year, leaving warm water and air in their wakes—and melting sea ice in the Arctic Ocean. That's about 40 percent more than previously thought,...Show More Summary
More studies look at links to extreme weather.
By Stephanie Pfirman This week, we are launching a test of “IceTracker”—a tool that allows users to see the trajectories of Arctic sea ice forward or backward from any day between 1981 and 2012, as well as other data including sea-ice speed, air temperature, water depth and the age of the sea ice along the [...]
Scientists huddled in a sea ice camp on the Arctic Ocean have produced new evidence that climate change could be threatening the food web in the far North. The researchers found that shrimp-like creatures eaten by everything from fish to whales are likely to react poorly to increasingly acidic water caused by high levels of […]
From sea-ice formation in November 2007 to onset of ice melt in May 2008, we studied the carbonate system in first-year Arctic sea ice, focusing on the impact of calcium-carbonate (CaCO3) saturation states of aragonite (?Ar) and calcite (?Ca) at the ice-water interface (UIW). Based on total inorganic carbon (CT) and total alkalinity (AT), and […]
A new study links the past decade’s “exceptional number of unprecedented summer extreme weather events” in the U.S. and Europe with the “record declines in both summer Arctic sea ice and snow cover on high-latitude land.” The post Arctic Warming Drives More Extreme Summer Heat Waves, Droughts And Deluges, Study Finds appeared first on ThinkProgress.
I'll just leave this here. And I'll save some of you the trouble of pointing out that the vertical scale does not go to zero (nor does the horizontal scale go to the beginning of time).Found at National Geographic.
For the past three decades, as the climate has warmed, the massive plates of sea ice in the Arctic Ocean have shrunk: In 2007, scientists observed nearly 50 percent less summer ice than had been seen in 1980. read more
The Arctic Ocean already experiences areas of low pH and high CO2, and it is expected to be most rapidly affected by future ocean acidification (OA). Copepods comprise the dominant Arctic zooplankton; hence, their responses to OA have important implications for Arctic ecosystems, yet there is little data on their current under-ice winter ecology on […]
Arctic boundary as defined by the Arctic Research and Policy Act. In the face of the reduction of Arctic ice that allowed 500 ships to sail the Northern Sea Route between Alaska and Russia in 2012—a 50 percent increase over the past decade that is expected to increase 10 times—the Pentagon has issued a 14-page white paper, Arctic Strategy.

The loss of seasonal sea ice in the Arctic will have ramifications for the U.S. Navy in terms of future missions, force structure, training and investments. To
In the nineteenth century, many people believed that the Arctic Sea was open water, ringed by ice. The country whose merchant vessels could find their way through that ice, and across the North Pole, would have a fantastic shipping route. Read more...

(HALIFAX, Nova Scotia) — The U.S. military is looking for ways to expand operations in the vast waters of the Arctic as melting ice caps open sea lanes, and other nations such as Russia compete for the lucrative oil and gas deposits....Show More Summary

Scientists predicted a decade ago that Arctic ice loss would shift storm tracks and bring on worse western droughts of the kind we are now seeing. Recent studies find that Arctic sea ice loss may well usher changes in the jet stream that lead to more U.S. extreme weather events. read more
