climate risk

Berkeley Earth is dedicated to advancing the field of climate science by providing open-source, high-resolution datasets that enhance the understanding of local climate dynamics and risks. In keeping with this ethos, today we introduce our forthcoming Climate Model Synthesis project, which aims to address critical gaps in existing climate models by applying bias correction and […]

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.

Marking Berkeley Earth’s tenth year of providing independent, open-source analysis of global average temperatures, the 2022 Annual Temperature Report finds that 2022 was nominally the fifth warmest on Earth since 1850. The last eight years have been the eight warmest years on record.

2022 was nominally the fifth warmest year since record keeping began in 1850, as La Niña as kept temperatures a bit cooler. 28 countries, including most of Western Europe, New Zealand, and China set new record high annual averages.
