Characterizing the relationship of extreme weather events to man-made global warming is essential for crafting effective mitigation policies and adaptation strategies.

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.

Globally, August 2023 was the warmest August since record-keeping began in 1850, breaking the previous record by a large margin. El Niño is underway and strengthening, and 2023 is virtually certain to become a record warm year.

Globally, July 2023 was the warmest month since record-keeping began in 1850. El Niño is underway and strengthening, and 2023 is virtually certain to become a record warm year.

Globally, June 2023 was the warmest June since record-keeping began in 1850. El Niño is underway and strengthening, and 2023 is now likely to become a record warm year.

Globally, March 2022 was the 5th warmest March since record-keeping began in 1850. Due to ongoing La Niña conditions, 2022 is projected to be around the 4th or 5th warmest year overall, with only a small chance of a new record.
