Thawing permafrost may help absorb carbon dioxide

For years, scientists have viewed thawing permafrost as a 'ticking time bomb.'

The logic was straightforward: as ground that has been frozen for millennia warms, microbes decompose ancient organic matter, releasing massive amounts of CO2 and methane into the atmosphere.

This creates a dangerous feedback loop, further accelerating global warming.

However, recent research on the Qinghai-Tibet Plateau suggests the story is more complex.

Scientists have discovered that as permafrost thaws, it exposes fresh rock minerals to the elements.

This triggers a process called chemical weathering, where water and air interact with these minerals to pull CO2 out of the atmosphere.
