A landmark United Nations climate report published Wednesday details the observed and anticipated future impacts of planet-heating emissions from human activity on the world’s oceans and frozen zones—and warns of the emerging consequences for humanity, marine ecosystems, and the global environment.

As climate scientists raise alarm over hotter and hotter global temperatures, a top U.S. weather agency reported on Thursday that July 2019 was the hottest month the planet has ever experienced since the government began recording global temperatures nearly 140 years ago.
NOAA’s monthly Global Climate Report revealed that last month the average worldwide temperature was 1.71 degrees Fahrenheit above the average temperature observed in the 20th century. Continue reading →

The climate crisis is rapidly warming the Arctic, and the effects are being felt from Alaska to Greenland.
The northernmost point on the planet is heating up more quickly than any other region in the world. The reason for this warming is ice–albedo feedback: as ice melts it opens up land and sea to the sun, which then absorb more heat that would have been bounced off by the ice, leading to more warming. It’s a vicious circle of warmth that’s changing the environment at the north pole.
In Alaska, the crisis led this year to the warmest spring on record for the state; one city, Akiak, may turn into an island due to swelling riverbanks and erosion exacerbated by thawing permafrost and ice melt. Massachusetts-based Woods Hole Research Center scientist Susan Natali toldThe Guardian that what’s happening in Akiak is just an indicator of the danger posed to Alaska by the climate crisis.

“Shocking,” “absolutely astonishing,” and “remarkable.”
That’s how climate scientists are describing the recent unusually warm temperatures in the Arctic.
As the Washington Postreported last week, the region is “stewing in temperatures more than 45 degrees (F) above normal. This latest huge temperature spike in the Arctic is another striking indicator of its rapidly transforming climate.” Continue reading →
What is happening in the Arctic will not stay in the Arctic.
In an ominous (though not hopeless) report published Friday, researchers warn that as many as 19 various ‘tipping points’ could be triggered by the increasingly warm temperatures in the world’s northern polar region.
The Arctic Resilience Report, produced under the auspices of the Arctic Council by an international team of researchers from multiple institutes and universities, is the first comprehensive assessment of its kind, looking at the unique region from a combined social and ecological perspective. By surveying and synthesizing a large body of previous research on how both communities and natural systems are responding to global warming, the report offers a worrying conclusion.
