Ozone Day reminder; the ozone layer may be healing high above us, but the ozone we breathe at ground level remains a serious public health threat.
Kolkata’s experience shows why we cannot confuse these two very different problems. Ground level ozone is formed by pollution + sunlight & can harm our lungs. @WMWestBengal

কলকাতার বাতাসে স্বস্তি নয়, সতর্কবার্তা। H1 2026-এ PM2.5 বেড়ে 45.7 µg/m³—গত বছরের 43.6 থেকে বেশি। বাংলার অন্য শহরগুলির উন্নতির বিপরীতে কলকাতার দূষণ বাড়ছে। পরিষ্কার বাতাস কি তবে কলকাতার জন্য এখনও দূরস্বপ্ন? #Kolkata #AirPollution
Kolkata's air quality improvement has stagnated, and it now needs regional airshed management.
