One of the most information-dense graphics in all of weather, and it's one that ordinary people can gain a lot from learning to read
"All of north India has been pushed into a medical emergency"
Air pollution, long a chronic condition in places like Delhi, has become an acute problem this year, leading one high-ranking politician to declare that "all of north India has been pushed into a medical emergency". It's a problem culminating from combustion engines, construction activity, agricultural fires, and other sources. Even fireworks are part of the debate. ■ Anything significant that happens in India already tends to have consequences for a noteworthy share of the world's population, but in this case, India is simply experiencing an acute encounter with a problem that plagues almost all of us from time to time. Just this summer, wildfires in Canada's west caused spikes in doctors' visits in Baltimore, Maryland. ■ In a parallel with that other inescapable necessity, water, the best way to fix air pollution is to prevent its creation at the source. But failing that, it seems like there's still a lot of public-health ground to gain by figuring out how to economically clean large volumes of outdoor air and ultra-purify indoor air. ■ Neither consideration is anything new; people have talked about ideas as far-out as building giant fans to blow the smog out of Los Angeles. But if non-point-source pollution looks like a big problem for water quality (and it is), then it's an even bigger problem for air. By nature, gases tend to spread. Whatever pollutants start bumping around with air molecules become very hard to capture again. ■ But given that lots of what gets us sick is just floating around amid our indoor air, there ought to be more energy going into improving air quality even for places that don't have Delhi-level pollution. ■ It does go to show what a misstep it has been for America's public consciousness to think of problems like air and water pollution as "environmental" issues. Sure, there's a sense in which they are; but what really matters is that they are health issues that harm and even shorten human life. That should command a lot of energetic attention.
