Globally, August 2024 was the warmest August since record-keeping began in 1850, continuing a 15-month streak of tied & broken records. 2024 is now almost certain to become the warmest year on record.

2023 was warmest year on Earth since direct observations began. In Berkeley Earth's analysis 2023 was 1.54 °C above our 1850-1900 average, making it the first year above 1.5 °C. The extreme heat was due to a combination of natural and man-made factors, including global warming and an emerging El Niño event. 17% of the Earth's surface had a locally warmest year, affecting 2.3 billion people, including significant parts of Asia, South and Central America.
