First model experiments suggest that by increasing the number of large herbivores in the Arctic, we could slow down permafrost thawing.
Researchers have detected novel viruses in samples of glacial ice, suggesting global heating could lead to the re-emergence of historic pathogens. But the science is uncertain.
Permafrost is ground that remains frozen for a period of two or more years.
Researchers found these regions of the eastern Arctic Ocean are relatively rare, which is "good news" for the climate.
The next decades, partly as a result of our inaction over the past ones, are crucial to mitigate climate warming. It is time to embrace innovative and proactive new experiments.
A method of extracting methane recently described in Scientific Reports could turn permafrost hydrate reservoirs into carbon sinks.
Scientists used buckets to scoop out methane bubbles from a spot in the Arctic sea.
The researchers were able to scoop the bubbling water out of the sea with buckets.
Phillip Williamson, lead author for the ocean chapter of the report, told Newsweek: "Our planet won't be the same again."
"We saw that microbial communities respond quite rapidly—within four or five years—to even modest levels of warming," said an author of the study.
Four million people living in the Arctic permafrost area will be affected by damage to infrastructure.
Thawing permafrost is releasing more carbon dioxide than previously thought.
The permafrost beneath certain lakes is thawing rapidly, which will release a significant amount of methane into the atmosphere.
The foal was discovered in the ice of Siberia's "mouth of hell."
While the finding could have exciting implications for many scientific fields, the thawing of permafrost may not be good news for humankind.
If the Arctic permafrost melts, greenhouse gasses equivalent to burning all of the world's forests two-and-a-half times over could be released.
"There would be no environmental problem if everything remained frozen, but we know the Earth is getting warmer."
The tomb appears to be both the oldest and largest of its kind ever recorded in southern Siberia.
Thawing permafrost in the city of Bethel is wreaking havoc on the local landscape.
Robust model shows for every one degree Celsius warming, 4 million square kilometers would be lost.
The effects of climate change are raising temperatures in the Arctic faster than anywhere else, posing a threat to structures as foundations disintegrate.
It's a vicious cycle: As the weather warms, the Earth's permafrost is melting, releasing greenhouse gases that are going to make the planet even hotter.
