But rising temperatures contribute to thawing permafrost and enhance the biogeochemical activities that exacerbate climate change by releasing greenhouse gases such as carbon dioxide (CO 2 ...

All permafrost thaw leads to greenhouse gas emissions. But standing water accelerates the threat. The gas that bubbles from the oxygen-deprived mud under ponds and lakes is not only carbon dioxide ...

However, despite clear signs of permafrost carbon inputs via active shore erosion, these sheltered ponds emitted modern to century-old greenhouse gases. As the ice-free period lengthens, scenarios of ...

a combination that could increase the climatological toll of greenhouse gases. The team of researchers explored caves in Canada to look for clues left in speleothemsmineral deposits accumulated over ...

The earth’s temperature is rising steadily. This global warming can be ignored, perhaps for a long time. However, it cannot ...

[1] As permafrost thaws, it releases the powerful greenhouse gas methane into the atmosphere, which contributes to further warming in a reinforcing feedback loop. Permafrost plays an essential role in ...

Colossal explosions shake a remote corner of the Siberian tundra, leaving behind massive craters. In Alaska, a huge lake erupts with bubbles of inflammable gas. Scientists are discovering that these ...

Also, "fires can thaw permafrost, beginning a cascade of microbial processes that may also generate greenhouse gases. The biggest problem is "that carbon will take at least another 1,000 years to ...

These include the melting of permafrost, the layer of previously permanently frozen ice within soil ... Methane does not persist for long in the atmosphere but is nevertheless a powerful greenhouse ...

The long, cold winters slow plants’ decomposition and lock them in the frozen ground. However, when permafrost holding this and other organic matter thaws, it releases more greenhouse gases into the ...
