Delhi's Diwali pollution spike began before fireworks were lit

Authorities and researchers point to factors such as seasonal weather patterns and ongoing emissions as likely drivers. The findings challenge the common assumption that festival fireworks are solely responsible for Diwali-season smog. The article calls for a broader look at pollution sources when planning measures to protect public health.
