Fingerprints of Arctic Warming Seen Throughout Region

Fingerprints of Arctic Warming Seen Throughout Region

The Arctic climate during the past year featured sharp swings between warm and cold extremes, the report found. For example, Eurasia had an unusually cold winter, but that was followed by spring air temperatures that were as much as 7°F above average. Meanwhile, unusually warm winter temperatures over the central Arctic Ocean, Greenland, and Baffin… Read More

Is the West’s Dry Spell Really a Megadrought?

Is the West’s Dry Spell Really a Megadrought?

The drought that has been afflicting most of the Western states for the last 13 years may be a “megadrought,” and the likelihood is high that this century could see a multi-decade dry spell like nothing else seen over the last 1,000 years, according to research presented at the American Geophysical Union Fall Meeting on Wednesday and Thursday.… Read More

While Most of U.S. Froze, Parts of Alaska Set Record Highs

While Most of U.S. Froze, Parts of Alaska Set Record Highs

Along Alaska's northern coastline, which lies above the Arctic Circle, the warmest December temperatures on record in at least 70 years occurred during the past week. At the airport in Deadhorse, which serves the oil production hub of Prudhoe Bay, the temperature hit 39 degrees on December 7, the highest December temperature on record there since a… Read More

Study Adds to Arctic Warming, Extreme Weather Debate

Study Adds to Arctic Warming, Extreme Weather Debate

While the study adds to the body of evidence pointing to the outsized role the Arctic is playing in shaping weather patterns, it failed to mark an end to the debate within the scientific community over whether and how what is happening in the Far North could be having such far-reaching impacts. There is virtually no controversy among climate scien… Read More

Arctic Blast Has Half the Lower 48 States In Its Icy Grip

Arctic Blast Has Half the Lower 48 States In Its Icy Grip

The weather pattern producing the cold air outbreak features a contorted jet stream that resembles a giant snake on a weather map, with a huge ridge of high pressure shunting the jet stream to the north of Alaska (bringing milder-than-average conditions there), only to come surging southward above the West, and carving out a deep trough across the … Read More

Gradual Climate Changes Could Cause Sudden Impacts

Gradual Climate Changes Could Cause Sudden Impacts

Abrupt shifts in the climate have already begun, with more possible by the end of this century according to a report released Tuesday by the National Research Council. At the same time, even gradual changes to the climate could reach tipping points, leading to more unforeseen impacts. The report recommends creating an early warning system, instead … Read More

For First Time in 20 Years, Cold Records May Beat Warm

For First Time in 20 Years, Cold Records May Beat Warm

That means that December will be a crucial month for determining the winner for 2013. The last time daily record lows outnumbered daily record highs in the U.S. was in 1992. The Arctic air mass moving south from Canada, which is set to send temperatures plunging from Seattle to Texas by the end of this week, tilts the odds in favor of cold temperat… Read More
