Characterizing the relationship of extreme weather events to man-made global warming is essential for crafting effective mitigation policies and adaptation strategies.
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.
Globally, February 2023 was the 5th warmest February since record-keeping began in 1850. La Niña has ended. Thus far, 2023 is on pace to be the 3rd, 4th, or 5th warmest year, but still has time to move higher or lower. If a strong El Niño develops later this year, a chance remains for 2023 to become a record warm year.
