The Air Quality Life Index annual report reveals the United States and Canada experienced the sharpest pollution increases globally due to record-breaking wildfires supercharged by climate change.
“I just don’t think this can be repeated enough: particulate matter remains the greatest external threat to human health on the planet, period,“ he told AFP.
Canada’s catastrophic 2023 wildfire season drove a more than 50% rise in particulate levels compared to 2022, while the United States saw a 20% increase.
“The very surprising finding to me is that in parts of the world, certainly Canada, certainly the US and it looks like parts of Europe as well, air pollution is like the zombie that we thought we had killed, and now it’s back,“ said Greenstone.
The hardest-hit regions were provinces of Northwest Territories, British Columbia, and Alberta, where particulate pollution levels rivaled those of Bolivia and Honduras, shortening lifespans by two years.
Latin America saw its highest level since 1998, with Bolivia the worst affected country.
There were some bright spots: within the European Union, particulate concentrations fell by 6%, while in Central and West Africa, they dropped by 8%. – AFP
