Bangkok Set for Region-Topping Temperatures in Years to Come: Study
Bangkok has deployed a network of 313 air‑conditioned cooling centres and 279 outdoor shade sites, serving more than 120,000 residents in the past month as the city endures a record heat wave. A new ASEAN Centre for Energy report projects the capital will experience up to 120 extreme‑heat days per year by 2050, nearly triple today’s 45 days, with daily highs reaching 38 °C. The heat surge threatens public health, strains energy supplies, and could erase $15.6 billion in annual productivity by mid‑century. Officials stress expanding passive‑design measures and green infrastructure to curb rising temperatures and inequality.
Colorado's Shrinking Snowpack Prompts Urgent Conservation Action
