Underwater Arctic forests are expanding thanks to global warming. Karen Filbee-Dexter explores how these important ecosystems are changing with the climate
The Antarctic Circumpolar Current is the planet's most powerful and arguably most important. It is the only one to flow clear around the globe without getting diverted by any landmass, sending up to 150 times the flow of all the world's rivers clockwise around the frozen continent.
As sea ice continues to melt, northern shipping is forecast to increase. A spill is a tragedy that can, and must, be averted.

NATIONAL HARBOR, Md. – The Coast Guard’s next icebreaker is based on a German research vessel, features a unique Finnish propulsion design and is driven by American diesels, shipbuilder VT Halter Marine told USNI News on Tuesday.
The Arctic sea-ice decline is among the most emblematic manifestations of climate change and is occurring before we understand its ecological consequences. We investigated future changes in algal productivity combining a biogeochemical model for sympagic algae with sea-ice drivers from an ensemble of 18 CMIP5 climate models.
ROVANIEMI, Finland — Under pressure from the United States, the Arctic Council issued a short joint statement on Tuesday that excluded any mention of climate change.
Secretary of State Mike Pompeo said Monday that the Arctic, a region that has been significantly impacted by climate change, presents "opportunity and abundance" when it comes to economic opportunity.
US secretary of state Mike Pompeo is to meet Russia's minister of foreign affairs Sergey Lavrov on Monday (6 May) in Rovaniemi, the main city in Finland's Arctic region, amidst tensions over both climate change and Chinese ambitions in the polar region.
As Arctic ice melts, we can physically see glaciers retreating. But what we can’t yet see is the exact effect climate change will have on the environment, humans, economies, and national security. Less ice for longer periods each year will likely bring opportunities and related challenges as Arctic and non-Arctic states jockey for position.
Washington, D.C. May 1, 2019 — In response to today’s U.S. House Natural Resources Committee vote passing the bipartisan Arctic Cultural and Coastal Plain Protection Act out of committee (the bill passed 22-14), Alaska Wilderness League, Natural Resources Defense Council, Sierra Club, The Wilderness Society, Friends of Alaska National Wildlife Refuges, Defenders of Wildlife, Environment America, Trustees for Alaska, Earthjustice, National Audubon Society, Center for Biological Diversity and Northern Alaska Environmental Center issue the following joint statement:
Beginning in April and continuing through September, NOAA scientists will conduct vessel surveys in the Bering Sea. Four of these are annual surveys that have been conducted for several decades, providing a good basis of data so scientists can detect trends and changes in the ecosystem.
A new study looking at the implications of increased shipping activity and the impact on Antarctic marine biodiversity. The research is an important step in the quest to understand whether invasive species, introduced by shipping, will find the Antarctic marine environment more hospitable as Antarctica's climate changes.
Researchers studying hi-res satellite imagery have discovered that emperor penguins at the Halley Bay colony in the Weddell Sea have failed to raise chicks for the last three years.
The northernmost town in the country had its warmest March on record. Utqiagvik, formerly known as Barrow, is among the coastal communities that are feeling the effects of a warming Arctic firsthand.
New science warns that melting ice and permafrost could set off feedback loops that make climate change worse
April 23 (UPI) -- The U.S. Coast Guard wants to add resources to the Arctic because "dramatic changes in the physical environment" of the region have allowed China and Russia to become more competitive there.

RESOLUTE BAY, Canada -- After finishing a training drill on surviving the bitter cold, the soldiers gathered around Ranger Debbie Iqaluk to hear about an inescapable fact of life in the high Arctic: The ice is melting despite the low temperatures. And that means the Russians are coming.
UTQIAGVIK, Alaska — Bryan Thomas doesn’t want any more “wishy-washy conversations about climate change.”
A recent study shows that nitrous oxide emissions from thawing Alaskan permafrost are about twelve times higher than previously assumed. About one fourth of the Northern Hemisphere is covered in permafrost, which is thawing at an increasing rate.
WASHINGTON - At this year's International Arctic Forum in St. Petersburg, Russian leaders made the most peaceable statements to date about Moscow's long-term plans for the a rapidly melting Arctic.

Saint-Petersburg based Admiralteiskie Verfi shipyard (a company of United Shipbuilding Corporation) says it has laid down the North Pole ice-resistant self-propelled platform of Project 00903 today, 10 April 2019, in the framework the ‘Arctic: Territory of Dialogue’ 5th International Arctic Forum.
After the timeframe for submitting comments on the draft Environmental Impact Statement for drilling in Arctic National Wildlife Refuge (ANWR) has closed, the organization Public Employees for Environmental Responsibility (PEER) claims that essential information was withheld from the public. Several sources also argue that the potential revenue from drilling is greatly overstated.
Two cracks on the Brunt Ice Shelf are creeping closer to each other. When they intersect, an iceberg twice the size of Manhattan will slide into the ocean.
Scientists from Russia and China will cooperate in the exploration of marine life and mineral resources in the deep sea, particularly in the Arctic region, Andrei Adrianov, vice-president of the Russian Academy of Sciences, said at a news conference on Wednesday.
In its annual rhythm of growth and melt, sea ice across the Arctic Ocean generally retreats throughout springtime. But not every region melts equally. By the end of April 2018, ice cover in the Bering Sea was far below average for the time of year.
Only 20 per cent of ice formed in the Russian shelf reaches the Central Arctic, compared to around 50 per cent 20 years ago, according to a new paper published on 2 April in Scientific Reports, an open access journal (1). The rest of the ice now melts before it can leave the “nursery.”
Increasing ground temperatures in the Arctic are indicators of global climate change, but until recently, areas of cold permafrost were thought to be relatively immune to severe impacts.
In a couple weeks as we hang up our winter jackets to welcome the warmth of spring, ice that has formed over the Arctic Ocean and Hudson’s Bay will be covering the largest area that it will reach in 2019. This is known as the annual maximum sea ice extent, which occurs at the very end of our winter.
Russia - The Sevmorput, a nuclear-powered LASH carrier / container carrier, has left the Port of Arkhangelsk* for the Gydan peninsula today, 21 March 2019. According to Atomflot, the ship is loaded with general cargo of different types for the Arctic LNG 2 project.
Accurately modeling melt rates in specific ice shelf locations is critical for forecasting how Antarctica’s ice sheet will respond to climate change.
Plummeting to the bottom of an icy sea bed, divers have completed the final part of a wharf deconstruction on the British Antarctic Survey (BAS) at Rothera Research Station. Two months of deconstructing the old wharf came to an end over the weekend with the first frame of a new 74-metre long wharf being lowered into place.
A piece of Aotearoa technology is being used to support Antarctic scientists to capture fascinating footage of life beneath the ice in McMurdo Sound in the Ross Sea. The stunning footage is just a snippet of what was recorded during 21 hours underwater this season.
Record low sea ice in 2018 sent ripples through the entire Arctic ecosystem
‘The main take home point is we’re asking for a supplemental EIS’
The ship was on a mission to resupply Antarctica’s McMurdo Station. The 150 crew members were reunited with family and loved ones Monday morning.
The German climate expedition to the Larsen C ice shelf in Antarctica has ceased. The reason is that the ice floes are momentarily too thick: up to ten metres at some places. This is too dense for the expedition ship Polar Stern to continue their mission.
A recently-launched satellite mission has captured precision data on the elevation of the Antarctic ice sheet proving a valuable addition to monitoring efforts in the region, according to work published this week in The Cryosphere.
