A Warming Loop
A new study shows that climate change is triggering feedback loops across Canada that make the problem worse. Wildfires and melting permafrost are releasing additional greenhouse gases, which in turn drive further warming.
How Much Worse
Researchers found these feedback loops could add 20 to 30 per cent more warming on top of current estimates for this century, a significant jump that isn't fully accounted for in existing climate models.
Why It Matters
Canada's vast boreal forests and northern permafrost make it a major player in these feedback effects. As fires burn more land and frozen ground thaws faster, the gases released accelerate warming beyond what scientists had previously projected.
