Dubai's glitzy skyline was obscured by a blanket of smog rated as "unhealthy" on Sunday as thousands of delegates attended a COP28 conference dedicated to the harmful effects of air pollution.
The air quality index reached 155 micrograms per cubic metre of PM2.5 pollution -- the fine particulate matter that is most harmful, as it can enter the bloodstream -- according to WAQI.info, a real-time pollution tracker.
