February 2025 was the third warmest February on record, behind 2024 and 2020. However, there is now a ~38% chance that 2025 will be the warmest year on record, which is 8% more than the estimate made last month.

Globally, January 2025 was the warmest January on record, surpassing January 2024 by 0.09 °C. This is a surprising result given the La Niña event that began in December. There is now a ~30% chance that 2025 will be the warmest year on record (up from ~6% from the start of the year).

2024 was warmest year on Earth since direct observations began. In Berkeley Earth’s analysis 2024 was 1.62 °C above our 1850-1900 average, making it the second year above 1.5 °C. The recent warming appears faster than expected.

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.

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 […]

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, 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.

Globally, November 2022 was the 11th warmest November since record-keeping began in 1850, and the 18th warmest on land. 2022 is likely to be the 5th warmest year overall.

Globally, October 2022 was the 3rd warmest October since record-keeping began in 1850, and the warmest on land. Due to ongoing La Niña conditions, 2022 is very likely to be the 4th or 5th warmest year overall.

Globally, September 2022 was the 4th warmest September 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.

Globally, August 2022 was the 3rd warmest August 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.

Globally, July 2022 was the 4th warmest July 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.
