'Atlantification' of Arctic Ocean Speeds Up

The Arctic Ocean is warming so rapidly that it may soon transform into an upper arm of the Atlantic Ocean, researchers say.

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.

Would it sound too good to be true if I was to say that there was a simple, profitable and underused agricultural method to help feed everybody, cool the planet, and revitalize rural America? I used to think so, until I started visiting farmers who are restoring fertility to their land, stashing a lot of carbon in their soil, and returning healthy profitability to family farms. Now I've come to see how restoring soil health would prove as good for farmers and rural economies as it would for the environment.

Reports of extreme snowfall in the Arctic might seem encouraging, given that the region is rapidly warming due to human-driven climate change. According to a new study, however, the snow could actually pose a major threat to the normal reproductive cycles of Arctic wildlife.

One common concern about vegan diets is whether they provide your body with all the vitamins and minerals it needs.

Many claim that a whole-food, plant-based diet easily meets all the daily nutrient requirements.

A new multiyear study found that people living or working within 2,000 feet, or nearly half a mile, of a hydraulic fracturing (fracking) drill site may be at a heightened risk of exposure to benzene and other toxic chemicals, according to research released Thursday by the Colorado Department of Public Health and Environment (CDPHE)
