June 2021: Hottest Month Ever Recorded

June 2021 has seen record-breaking temperatures worldwide, with global air and sea surface temperatures surpassing previous records for the month. Many regions, including the Arab world, southern Europe, and Asia, experienced searing heat, leading to devastating consequences such as wildfires in Canada and a rising death toll from a heatwave in Mexico. Researchers attribute the increased intensity of the heat dome over Southern America to human-made climate change. The oceans are also warmer than ever, and global sea ice was at an all-time low for June. The planet is entering an El Niño period, which is expected to bring even warmer temperatures. Urgent and substantial reductions in fossil-fuel emissions are needed to address these climate challenges.
