The white nationalist rally masquerading as a pro-pipeline truckers' protest clogging the streets of Ottawa is, well, boneheaded.
They seem to have lost sight of the massive wildfire that nearly consumed their cherished Fort Mac and the climate change that turned the boreal forest into tinder. They don't care. All they're concerned about is fossil fuel, especially the highest carbon ersatz petroleum, bitumen.
It's clear that most climate change, especially in the northern hemisphere, is driven by the rapidly warming Arctic. Most of that is caused by the loss of snow, sea ice and the retreating Greenland ice cap. And what is causing the loss of all that reflective ice and snow? A lot of it is caused by black carbon being carried into the far north.
For a while it was thought that wildfires in the northern forests and tundra were the main culprits. That was wrong. New research has discovered that the main source of black carbon across the Arctic is fossil fuels.
The five-year study to uncover sources of black carbon was done at five remote sites around the Arctic and is published in the journal Science Advances.
The Baylor team used radiocarbon to determine fossil and biomass burning contributions to black carbon in Barrow, Alaska, while their collaborators used the same technique for sites in Russia, Canada, Sweden and Norway.You could say that trying to flood world markets with dirt cheap, high-carbon bitumen is like cutting our own throats. You could say that. Really, you could.
