Summary:
- The article discusses the phenomenon of "exploding craters" in the Siberian permafrost, which have been observed with increasing frequency in recent years.
- These craters are formed when methane gas trapped in the thawing permafrost builds up pressure and eventually erupts, creating large, crater-like depressions in the landscape.
- The article explains that the increasing occurrence of these craters is a concerning sign of the impacts of climate change, as the thawing of the permafrost is releasing significant amounts of greenhouse gases into the atmosphere, potentially further exacerbating global warming.
