In Southeast Asia, some countries posted their highest ever recorded temperatures this week, while searing heat in the Indian subcontinent has killed more than a dozen people. Laos is the latest country to set a new all-time record as Luang Prabang reached 42.7°C (109°F) Tuesday, according to weather historian Maximiliano Herrera. Over the weekend, Thailand topped 45°C (113°F) for the first time in its history, according to Herrera, using data from the Thai Meteorological Department. The northwest city of Tak reached 45.4°C Saturday, but large portions of the country have been in the upper 30s to low 40s since late March.
