A toxic haze has repeatedly wafted over huge swaths of Southeast Asia in the last month, causing school closures, grounded flights, canceled events and widespread concern about public health risks across the region. Here’s what you need to know about the Great Haze of 2015.
Nearly 100,000 fires are burning, setting up what looks to be the worst fire year in the region since 2006. The carbon emissions from the blazes have now surpassed those of the entire United States — the world’s second-largest emitter of greenhouse gases — on 26 out of 44 days since September, according to a report by the World Resources Institute.
That’s because about half the fires are in peatland areas — concentrated mainly in South Sumatra, South and Central Kalimantan, and Papua — that are among Earth’s biggest carbon storehouses.
Compared with ordinary fires, peat fires can emit up to 10 times more methane, a greenhouse gas whose impact on climate change is 25 times more potent than carbon dioxide, according to the U.S. Environmental Protection Agency.
