Trees absorb carbon from the atmosphere and store it, simply put, as wood. But when something comes along and kills trees (in this case, pine beetles), that carbon is released back into the atmosphere as the trees decompose, or worse, as they burn in forest fires.
Humans aren't off the hook. Blame milder winters, driven by manmade climate change, for the severity of our pine beetle problem here. Milder winters mean bigger pine beetle populations.
This is what scientist mean when they talk about the snowball-effect in global warming. Once the first domino tips, they keep falling, and falling.
According to the Telegraph article, 7.5 percent of Canada's carbon emissions are caused by the pine beetle disaster. Over the next 12 years, this problem will send 990 million tons of carbon dioxide into the atmosphere.
Speaking of snowball-effect, the Independent added that, as oceans warm, they are less capable of absorbing CO2 from the atmosphere. Oceans absorb about a quarter of the CO2 we humans crank out each year.
