Starting in April 2023, a record-breaking heat wave has affected many Asian countries, including India, Sri Lanka, Bangladesh, Cambodia, China, Laos, Thailand, Malaysia, Singapore and Vietnam. Several regional temperature records have been set. The heat wave has caused many deaths due to heat stroke and has prompted health warnings and power outages across multiple countries.
A May study by the World Weather Attribution found that the heat wave was made at least 30 times more likely by climate change in India and Bangladesh, and that climate change raised temperatures by at least 2 °C (3.6 °F) in many parts of Asia in April.
