"Among the most rapidly changing parts of our planet are the coldest landscapes
near the top of the globe, just south of the Arctic. This region is warming two
to four times faster than the global average.
The frozen ground beneath these “boreal” forests and treeless plains or
“tundra” is thawing, fast. That’s a problem because the permafrost holds
enormous amounts of vulnerable carbon, more than twice as much carbon as is
already present in the atmosphere. Some of that carbon is now on the move.
We wanted to find out just how much carbon and nitrogen is being released from
the northern permafrost region. The environment can be a source of greenhouse
gases, or a “sink” – effectively soaking up carbon and removing it from the
atmosphere. So we had to determine and balance the budget.
As part of the Global Carbon Project, we have now published the first full
greenhouse gas budget tallying sources and sinks for the northern permafrost
region. It contains a mixed bag of good and not-so-good news for the climate."
