The number of fires in the vast north Asian region of Siberia increased fivefold this week, according to the Russian forest fire aerial protection service, as temperatures in the Arctic continued higher than normal in the latest sign of the ongoing climate crisis.
The news of the increase comes a week after the small Siberian town of Verkhoyansk reported a high temperature of 100.4° F on June 20, a reading that, if confirmed, would mark the hottest day ever recorded in the region. Continue reading →
As experts warn that the world is running out of time to head off severe climate change, discussions of what the U.S. should do about it are split into opposing camps. The scientific-environmental perspective says global warming will cause the planet severe harm without action to slow fossil fuel burning. Those who reject mainstream climate science insist either that warming is not occurring or that it’s not clear human actions are driving it.

In addition to warning that “the feedback to accelerating climate change may already be underway,” the U.S. government’s latest report on conditions in the Arctic reveals that temperatures in the region are persistently warming, leading to land and sea ice melting, permafrost thawing, species being threatened with extinction, and putting Native communities at risk.
The National Oceanic and Atmospheric Administration on Tuesday published its 14th annual Arctic Report Card (pdf), which warns that “the Arctic marine ecosystem and the communities that depend upon it continue to experience unprecedented changes as a result of warming air temperatures, declining sea ice, and warming waters.” Continue reading →

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.

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.

As the Arctic enters an “unprecedented” state of warming, a new study shows that emissions of a potent greenhouse gas from thawing permafrost in the planet’s northernmost region may be 12 times higher than previously thought.
That’s according to a study published this month in the journal Atmospheric Chemistry and Physics. The paper’s findings add even more weight to scientists’ urgent warnings about the mounting threats of permafrost thaw. 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.
