Squirrelly

BBC:

“Carbon has been accumulating in permafrost for tens of thousands of years. The temperature is very cold, the soils are saturated, so that when plants and animals die, rather than decompose, the carbon has been slowly, slowly building up. “Right now the carbon storage is about 1,500 petagrams (1,500 billion tonnes). To put that in perspective, that’s about twice as much as is contained in the atmosphere.” The fear is that as the planet warms, the permafrost will thaw, releasing even more greenhouse gases into the atmosphere and causing temperatures to rise further still…

“If ground squirrels are adding nitrogen to an area – and that area doesn’t have plants because they dug them up – this may result in increased loss of carbon from the system.” She concluded that squirrels were playing “a far more important role in this permafrost carbon cycle than we thought”. The team now wants to return to the area to quantify how much carbon is being unlocked by the squirrels

Squirrels? And we thought cows were the greatest threat to the planet. Can’t keep us with all this. (And in case you’re looking for something that’s a bit of fun, don’t read this.)
