Latest Climate of the Arctic Stories

2012-04-04 20:35:14

Today the U.S. National Research Council released a synthesis of reports from thousands of scientists in 60 countries who took part in the International Polar Year (IPY) 2007-08, the first in over 50 years to offer a benchmark for environmental conditions and new discoveries in the polar regions. University of Massachusetts Amherst geosciences researcher and expert in the paleoclimate of the Arctic, Julie Brigham-Grette, co-chaired the NRC report, "Lessons and Legacies of the IPY 2007-08"...

Diminishing Arctic Sea Ice Linked To Colder, Snowier Winters
2012-02-28 05:51:56

Melting Arctic sea ice will mean colder winters with more snow in the Northern Hemisphere, according to a new study published Monday in the Proceedings of the National Academy of Sciences. The research provides further evidence of a relationship between melting ice in the Arctic regions and extensive cold outbreaks across northern continents. The study could also help improve seasonal forecasting of snow and temperature anomalies throughout Europe, North America and China, the...

Even In Winter, Life Persists In Arctic Seas

Results of research cruise to Bering, Chukchi and Beaufort seas surprise scientists and may have implications for climate modeling Despite brutal cold and lingering darkness, life in the frigid waters off Alaska does not grind to a halt in the winter as scientists previously suspected. According to preliminary results from a National Science Foundation- (NSF) funded research cruise, microscopic creatures at the base of the Arctic food chain are not dormant as expected. After working...

Europe Hammered By Winter, Is North America Next?

For the first half of this year's winter, the big news was warm temperatures and lack of snow. Ski resorts were covered in bare dirt, while January temperatures in southern California topped July highs. Then, out of the blue, Europe got clobbered: Over the past two weeks, temperatures in Eastern Europe have nose-dived to -30 degrees Celsius (-22 degrees Fahrenheit). Blizzards and the bone-chilling cold have resulted in the deaths of over 550 people so far, with rooftop-high snow drifts...

Image 1 - Link Found Between Summer Arctic Sea Ice Cover And Winter Weather In Central Europe

Even if the current weather situation may seem to speak against it, the probability of cold winters with much snow in Central Europe rises when the Arctic is covered by less sea ice in summer. Scientists of the Research Unit Potsdam of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association have decrypted a mechanism in which a shrinking summertime sea ice cover changes the air pressure zones in the Arctic atmosphere and impacts our European winter weather....

New Study Sheds Light On Little Ice Age
2012-01-30 15:44:41

University of Colorado researchers report that they have answered some questions surrounding Earth's Little Ice Age, which started between A.D. 1275 and 1300, and lasted into the late 19th century. According to the new study, the Little Ice Age was triggered by repeated, explosive volcanism and sustained by a self-perpetuating sea ice-ocean feedback system in the North Atlantic Ocean. Professor Gifford Miller, who led the study, said the team's evidence from radiocarbon dates from dead...

Cold Winters May Be Caused By Warmer Summers
2012-01-14 04:15:14

Scientists have offered up a convincing explanation for the harsh winters recently experienced in the Northern Hemisphere; increasing temperatures and melting ice in the Arctic regions creating more snowfall in the autumn months at lower latitudes. Their findings may throw light on specific weather incidents such as the extremely harsh Florida winter of 2010 which ended up killing a host of tropical creatures, as well as the chaos-causing snow that fell on the UK in December 2010....

Arctic air temperatures were approximately 2.5 degrees Fahrenheit higher in 2011 than the baseline number for the previous three decades, and the region continues to lose ice sheet and glacier mass at a "dramatic" rate, according to a new report released by an international team of scientists Thursday. The 2011 Arctic Report Card, which was compiled by a team of 121 scientists from 14 different countries, measures the status of the area in five different categories: atmosphere, sea ice and...

The National Snow and Ice Data Center reports that Arctic sea ice continues to shrink each summer to nearly record low levels, with this year´s ice loss the second-lowest ever since records first began being taken in 1979. Despite only a few decades worth of records, a new study, published in the British journal Nature, found that “both the duration and magnitude of the current decline in sea ice seem to be unprecedented for the past 1,450 years,” reported the authors. The...

Arctic Sea Ice At Second-lowest Level Since 1979
2011-09-16 04:32:17

  The extent of Arctic Ocean sea ice fell to its second-lowest size since 1979, the U.S. National Snow and Ice Data Center (NSIDC) said on Thursday. According to preliminary findings, the annual sea ice minimum was reached on September 9, when the ice covered 1.67 million square miles, the center said in a statement. "Changing winds could still push ice flows together reducing ice extend further," the researchers said. A full analysis will be available early next month, when...
