Methane (CH4) is a potent greenhouse gas that is roughly 30 times more harmful to the climate than carbon dioxide (CO2). Both gases are produced in thawing permafrost as dead animal and plant remains are decomposed. However, ...

For years, scientists have pointed to warming permafrost in the Arctic tundra as a source for increased carbon in the atmosphere; as this soil warms, it releases greenhouse gases that have long been trapped in frozen ground.
