Severe Alaskan wildfires have released much more carbon than was stored by the region's forests over the past 10 years, researchers report today. They warned that the pattern could lead to a "runaway climate change scenario" where larger, more intense fires release more greenhouse gases that, in turn, lead to more warming.
The northern wildfires burn peatlands that consist of decaying plant litter, moss and organic matter in the soil, said Merritt Turetsky, an ecologist at the University of Guelph in Canada and lead author of a new study. Such fires have a huge impact given that the peat

Sorry to here about the fire but as for the climate change the whole solar system is heating up.
They can do as many studies on carbon release or green house gasses as they want but it is just another way of imposing new taxes and rules.
The next thing they might say is the green house gasses are excaping earth and heating up everything from Mars to Pluto and they have to impose a new carbon tax and green house tax to stablize solar warming.
Its just another cash cow idea.
That's true for forest fires and brush fires, but that's not what the article is about so I'm guessing you didn't read it?

No offence to the OP. But this article is nonsense.
As an Australian Aboriginal, I can say with all certainty that forest/bush fires are meant to happen and man should not stand in their way.
It's a peat fire with thousands of years worth of carbon accumulation being released.
The northern wildfires burn peatlands that consist of decaying plant litter, moss and organic matter in the soil, said Merritt Turetsky, an ecologist at the University of Guelph in Canada and lead author of a new study. Such fires have a huge impact given that the peatlands contain much of the world's soil carbon - about as much carbon as is found in the atmosphere or in the total of terrestrial biomass (plants and animals).
"These findings are worrisome, because about half the world's soil carbon is locked in northern permafrost and peatland soils," Turetsky explained. "This is carbon that has accumulated in ecosystems a little bit at a time for thousands of years, but is being released very rapidly through increased burning."
The fire-chasing researchers found that burned area has doubled in Alaska's interior over the last decade. They traveled to almost 200 forest and peatland burn sites so that they could measure how much biomass had gone up in smoke and flames, and also examined fire records dating back to the 1950s.
Well in the past, it wasn't easy to catch fire, which is why it was able to accumulate plant matter for thousands of years. But they are pointing out that it's not as frozen as it used to be (we know glaciers are retreating etc), so that may be part of the problem, that it's a little easier to burn or start in some areas now that aren't as cold or as frozen.

It probably is not that easy to catch on fire either being permanently frozen, so that's the good news.
