Large amounts of methane have been observed escaping from the seabed off of the northeastern coast of Siberia, emanating from previously-frozen pockets of the powerful greenhouse gas, a “sleeping giant” that threatens to trigger a global warming feedback loop that exacerbates the climate-warming effects of human-produced carbon dioxide emissions.

Global warming may have pushed Greenland’s ice sheets past a tipping point, with the island having lost ice from its glaciers faster than snowfall could replenish them over the past two decades, according to a new study. Although this trend is expected to worsen as global temperatures increase, the researchersread more
The annual rate of ice melt in Greenland is now nearly eight times faster than it was in the early 1990s, according to a large-scale 6-year study that involved 89 scientists employing that data from 26 separate satellite analyses, coming to the conclusion that Greenland’s glaciers are (once again) meltingread more
An abandoned repository of over 3.1 million cubic feet (87,782 cubic meters) of radioactive debris left over from nuclear testing in the South Pacific is in danger of being cracked open by rising ocean levels, threatening to spill large amounts of the nuclear waste contained within—including highly-toxic plutonium—into the surroundingread more
