Where Data Tells the Story

🚨💨 Delhi’s air pollution crisis isn’t a seasonal glitch—it’s a 365-day emergency.
New satellite-derived monthly average population-weighted PM2.5 data from biteSizedAQ reveals a stark and worsening reality. While public attention peaks only during winter months, the data shows that air pollution levels remain dangerously high year-round, with long-term trends moving in the wrong direction:
This isn’t just a winter menace—it’s an around-the-clock assault on every lung and every heartbeat. And while this particular dataset focuses on Delhi, the trend generally holds across the wider Indo-Gangetic Plain, the most polluted region in the world.
Yet, policies and public discourse still follow the "winter calendar"—with monitoring, enforcement, and action largely relatively dormant from spring (Feb-March) to early autumn (October Start).
The progress from all the action in winter months is in large parts undone by the slack of summer months due to the faulty assumption that non-winter months are somehow not polluted. They might be less polluted then winter months, but they are still severely polluted. That is the key message.
We need a 365-day action plan, not just seasonal fixes. That means:
The next decade’s maps must show a decline—not a relentless climb.
Don’t wait for December’s headlines.
