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.
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.
BERKELEY, CA — Berkeley Earth today released its annual report on global mean temperature, concluding that while 2021 was significantly colder than 2020, it was nominally the sixth warmest year on Earth since 1850, 1.2 degrees Celsius (2.2F) above the 1850 to 1900 average. Given the uncertainties associated with temperature measurements, the years 2015, 2018, […]
2021 was nominally the sixth warmest year since record keeping began in 1850. 25 countries, including China, Nigeria, and South Korea, set new record high annual averages.
Berkeley Earth, a California-based non-profit research organization, has been preparing independent analyses of global mean temperature changes since 2013. The following is our report on global mean temperature during 2020. We conclude that 2020 was nominally the second warmest year on Earth since 1850. Our estimate of the global mean temperature in 2020 was slightly […]
Cooling weather may have caused increased COVID-19 spread. Considered across many regions, the average reproduction number (R) gradually increased from ~1.0 to ~1.2 as daily high temperatures fell from >27 °C to ~10-15 °C (>80 °F to 50-60 °F). Other factors, including decreases in sunlight and/or UV exposure, may have slightly increased this further.
Globally, November 2024 was the second warmest November since record-keeping began in 1850. Though recent extraordinary warmth has begun to wane, 2024 remains almost certain to become the warmest year on record.
Globally, October 2024 was nominally the second warmest October since record-keeping began in 1850, though also essentially tied with 2023. 2024 is now almost certain to become the warmest year on record.
Globally, August 2024 was the warmest August since record-keeping began in 1850, continuing a 15-month streak of broken & tied records. 2024 is now almost certain to become the warmest year on record.

Globally, April 2024 was the warmest April since record-keeping began in 1850. This year is very likely to become either the warmest or 2nd warmest on record.
Globally, March 2024 was nominally the warmest March since record-keeping began in 1850, though only by a tiny margin. This year is very likely to become either the warmest or 2nd warmest on record.
Globally, February 2024 was the warmest February since record-keeping began in 1850, breaking the previous record by a small margin. This year is very likely to become either the warmest or 2nd warmest on record.
Globally, January 2024 was the warmest January since record-keeping began in 1850, breaking the previous record by a small margin. This year is very likely to become either the warmest or 2nd warmest on record.
Globally, November 2023 was the warmest November since record-keeping began in 1850, breaking the previous record by a large margin. 2023 is virtually certain to become a record warm year, and be 1.5 °C above our preindustrial average.
Globally, September 2023 was the warmest September since record-keeping began in 1850, breaking the previous record by a enormous margin. 2023 is virtually certain to become a record warm year, and likely to be 1.5 °C above preindustrial.
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, May 2023 was the 3rd warmest May since record-keeping began in 1850. A return of El Niño is ongoing, and 2023 is now slightly more likely than not to become a record warm year.
Globally, April 2023 was the 4th warmest April since record-keeping began in 1850. A return of El Niño is expected, and 2023 is now slightly more likely than not to become a record warm year.
Globally, March 2023 was the 2nd warmest March since record-keeping began in 1850. Thus far, 2023 is on pace to be the 2nd, 3rd, or 4th warmest year, but a significant chance of a new record exists. El Niño is likely to develop later this year.
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.
