A study published this week in Nature Climate Change shows how the Barents Sea in Scandinavia, where Atlantic waters enter the Arctic basin, has become a warming "hot spot," with temperatures spiking 2.7 degrees F since 2000.
The changes and accompanying loss of sea ice have caused the sea to exhibit qualities more in common with the Atlantic ocean, including most notably a sharp upward tick in salinity. "Model simulations have indicated Atlantic-type conditions in the northern Barents Sea by the end of the century, but according to our results, this is likely to happen much faster," researchers wrote.
As reported by Earther:
What that means for the region and the Arctic as a whole is an open question. We're already witnessing weird happenings in the Arctic every year at this point, from bizarre winter sea ice disappearances to heat waves at the North Pole to massive storms. Scientists are racing to understand these changes. What saltier, warmer seas mean for the ocean creatures that inhabit the region, the fisheries that have relied on them, and the future of ice are just a few more questions that need urgent attention.

'Kicking Ass for Her Generation': Applause for 16-Year-Old Greta Thunberg as EU Chief Pledges $1 Trillion to Curb Climate Threat
By Julia Conley
Sixteen-year-old climate action leader Greta Thunberg stood alongside European Commission President Jean-Claude Juncker Thursday in Brussels as he indicated—after weeks of climate strikes around the world inspired by the Swedish teenager—that the European Union has heard the demands of young people and pledged more than $1 trillion over the next seven years to address the crisis of a rapidly heating planet.
In the financial period beginning in 2021, Juncker said, the EU will devote a quarter of its budget to solving the crisis.
‘Plastic Is Lethal’: Groundbreaking Report Reveals Health Risks at Every Stage in Plastics Life Cycle
With eight million metric tons of plastic entering the world's oceans every year, there is growing concern about the proliferation of plastics in the environment. Despite this, surprisingly little is known about the full impact of plastic pollution on human health.
But a first-of-its-kind study released Tuesday sets out to change that. The study, Plastic & Health: The Hidden Costs of a Plastic Planet, is especially groundbreaking because it looks at the health impacts of every stage in the life cycle of plastics, from the extraction of the fossil fuels that make them to their permanence in the environment. While previous studies have focused on particular products, manufacturing processes or moments in the creation and use of plastics, this study shows that plastics pose serious health risks at every stage in their production, use and disposal.
Air pollution within the home causes 3.8 million deaths a year, according to the World Health Organization. A recent University of Colorado in Boulder study reported by The Guardian found that cooking a full Thanksgiving meal could raise levels of particulate matter 2.5 in the house higher than the levels averaged in New Delhi, the world's sixth most polluted city.
