CDMX lives under a moving sky: ozone peaks on hot, still afternoons; PM2.5 rises with inversions, fires, and traffic; dust and construction add their own layer. Heat waves and storm bursts stress streets, trees, and people.
Air and climate aren’t abstract—they change school days, outdoor work, commuting choices, and power demand. Parks, trees, and water bodies cool blocks; traffic, industry, and open burning push in the other direction.
Real progress is measurable: hourly IMECA, hospital visits, shade coverage, and enforcement that matches what residents see on the street. We follow the documents, the data, and the lived reality.
