Alaska's Shorebirds Exposed to Mercury

July 13, 2016 — Shorebirds breeding in Alaska are being exposed to mercury at levels that could put their populations at risk, according to new ... read more

July 12, 2016 — Algae that live in and under the sea ice play a much greater role for the Arctic food web than previously assumed. In a new study, biologists show that not only animals that live directly under the ... read more

Vegetation in Russian Arctic Has Memory

June 27, 2016 — Adaptation to climate change has a lag of several thousands of years, report researchers. The permafrost regions in the Arctic are among those areas of the world in which the temperature is rising ... read more

June 24, 2016 — The Siberian permafrost regions include those areas of the Earth, which heat up very quickly in the course of climate change. Nevertheless, biologists are currently observing only a minimal response ... read more

June 23, 2016 — Finding out which is the highest mountain in the US Arctic may be the last thing on your mind, unless you are an explorer who skis from the tallest peaks around the globe. A ski mountaineer and a ... read more

June 22, 2016 — Analysis of nearly three decades of air samples from Alaska's North Slope shows little change in long-term methane emissions despite significant Arctic warming over that time period, according ... read more

June 22, 2016 — The role of red pigmented snow algae in melting Arctic glaciers has been strongly underestimated, suggests a study. The new work shows a 13 percent reduction of the albedo over the course of one ... read more

June 16, 2016 — Permafrost below shallow Arctic lakes is thawing as a result of changing winter climate, new research shows. These rates of warming are similar to those observed in terrestrial permafrost, yet those ... read more

June 13, 2016 — Soil moisture levels will determine how much carbon is released to the atmosphere as rising temperatures thaw Arctic lands, suggests new scientific ... read more

June 13, 2016 — Carbon dioxide emissions from dry and oxygen-rich environments are likely to play a much greater role in controlling future rates of climate change caused by permafrost thaw than rates of methane ... read more

June 9, 2016 — Following record-high temperatures and melting records that affected northwest Greenland in summer 2015, a new study provides the first evidence linking melting in Greenland to the anticipated ... read more

June 2, 2016 — The northern reaches of North America are getting greener, according to a study that provides the most detailed look yet at plant life across Alaska and Canada. In a changing climate, almost a third ... read more

June 1, 2016 — Through geologic time the cold temperatures of Alaska have led to the storage of vast quantities of soil and biomass carbon. A major concern for this region is how interactions among warming, ... read more

June 1, 2016 — Shifts in the distribution of Spectacled Eiders, a predatory bird at the top of the Bering Sea's benthic food web, indicate possible changes in the Arctic's marine ecosystem, according to ... read more

May 27, 2016 — 250 methane flares release the climate gas methane from the seabed and into the Arctic Ocean. During the summer months this leads to an increased methane concentration in the ocean. But surprisingly, ... read more

May 25, 2016 — A new paper explains why some climate processes are more effective than others at warming/cooling the Earth. By accounting for these differences we can more accurately determine the most important ... read more

May 25, 2016 — Black carbon aerosols are important for understanding climate change. Unfortunately, current simulation models consistently underestimate the amount of these aerosols in the Arctic compared to actual ... read more

May 23, 2016 — The history of Greenland's snowfall is chronicled in an unlikely place: the remains of aquatic plants that died long ago, collecting at the bottom of lakes in horizontal layers that document the ... read more

May 17, 2016 — Climate change creates more shrub vegetation in barren, Arctic ecosystems. A new study shows that organisms, such as bacteria and fungi, are triggered to break down particularly nutritious dead parts ... read more

May 10, 2016 — Climate change is melting glaciers, reducing sea-ice cover and increasing wildlife activity -- with some of the most dramatic impacts occurring in the northern high latitudes. New research projects ... read more
