Wildfire smoke in Pacific north-west erasing reductions in emissions – study
Billowing black smoke during wildfire disasters has caused atmospheric carbon monoxide levels to increase, scientists find
The billowing black smoke that has cloaked the US Pacific north-west during wildfire disasters in past years has caused atmospheric carbon monoxide levels to spike, with the contaminants offsetting recent reductions in emissions, scientists at the National Center for Atmospheric Research have found.
As the American west faces increasing threats from big blazes that are fueled by a climate that's growing warmer and drier, researchers have documented the impact of smoke on public health. But scientists are increasingly finding that the fires may be part of a feedback loop that could accelerate the change in conditions and that health impacts officials have long warned would worsen with climate crisis, may in fact already be here.
