The Earth is dimming as it reflects less sunlight back into space, with the Northern Hemisphere darkening far faster than the south—intensifying global warming risks.

It’s a small act, but when millions join in, it speaks volumes. Bangkok Governor Chadchart Sittipunt is calling on city dwellers to take part in a global movement—60+ Earth Hour 2025. For just one hour, from 8:30 PM to 9:30 PM on Saturday, March 22, Bangkokians will switch off non-essential lights and unplug unused electrical devices, joining millions across 190 countries and 7,000 cities in a symbolic yet powerful gesture against climate change.
