Catastrophic Canadian warming-fueled wildfires last year pumped more heat-trapping carbon dioxide into the air than India did by burning fossil fuels, setting ablaze an area of forest larger than West Virginia, new research found.
Forests “remove a lot of carbon from the atmosphere and that gets stored in their branches, their trunks, their leaves and kind of in the ground as well. So when they burn all the carbon that’s stored within them gets released back into the atmosphere,” said study lead author James MacCarthy, a research associate with WRI’s Global Forest Watch.
These are far more than regular forest fires, but researchers focused only on tree cover loss, which is a bigger effect, said study co-author Alexandra Tyukavina, a geography professor at the University of Maryland. “Because of these catastrophic fires, air quality in populated areas and cities was affected last year,” she said, mentioning New York City’s smog-choked summer. More than 200 communities with about 232,000 residents had to be evacuated, according to another not-yet-published or peer-reviewed study by Canadian forest and fire experts.
