RESIDENTS OF ANCHORAGE, Alaska, found themselves enjoying a stretch of relatively balmy weather this past December, with temperatures at times climbing above freezing. More southerly cities near the Canada-U.S. border, meanwhile, sat in the grip of a deep freeze, with some double-digit temperature drops triggering extreme cold weather alerts.
Grab Your Ear Muffs, the New Year’s Arriving With a Frigid Bang
A deep freeze is about to descend on North America, Europe and Asia thanks to record high temperatures across the Arctic. How’s that? “Think of it like a seesaw,” said Matt Rogers, president of Commodity Weather Group LLC in Bethesda, Maryland. If winter temperatures rise north of Alaska, that “forces an equal-opposite downward-southward push. The cold essentially has to go somewhere else.”
Starting off 2017 with an actual Seattle freeze
It will be a cold start to 2017 in the Seattle area. Forecasters say that as the ball drops New Year's Eve, a cold front starts moving into the northwest from Canada. Washington state's climatologist, Nick Bond, is monitoring the weather pattern.
The Arctic is ‘behaving so bizarrely,’ and these scientists think they know why
Last month, temperatures in the high Arctic spiked dramatically, some 36 degrees Fahrenheit above normal — a move that corresponded with record low levels of Arctic sea ice during a time of year when this ice is supposed to be expanding during the freezing polar night.
Unexplored Ocean Depths Bustling with Life, Despite Extreme Conditions
A team of leading geologists, chemists, and biologists aboard research vessel Falkor have just finished surveying the largely unexplored Mariana Back-Arc for life at depths greater than 13,000 feet. Dr. David Butterfield, JISAO, University of Washington, and Dr. William Chadwick, NOAA-PMEL and Oregon State University, led the group to the Back-Arc
