El Nino

June 2026 was the 2nd warmest June on record. El Niño is growing rapidly and is likely to reach record high intensity by the end of the year.

A record-setting European heatwave, wildfires across Canada and France, and a strong El Niño taking shape in the Pacific. This summer has produced a run of extreme, headline-making weather: the warmest June ever measured for the world’s oceans, a lethal heatwave across France, wildfires across Canada and Europe, and the early arrival of a powerful […]

June 2026 was the 2nd warmest June on record. El Niño is growing rapidly and is likely to reach record high intensity by the end of the year.

2025 was the 3rd warmest year on Earth since direct observations began. In Berkeley Earth’s analysis 2025 was 1.44 °C above our 1850-1900 average. The recent rate of warming is faster than historical trends. Extra warming appears to be related to a recent decrease in low cloud cover and man-made sulfur aerosols.

Berkeley, CA – Berkeley Earth, an independent, California-based non-profit climate monitoring organization, today released its 2025 Annual Temperature Report, concluding that 2025 was the third warmest year on Earth since 1850, exceeded only by 2024 and 2023. In Berkeley Earth’s analysis, the global annual average temperature in 2025 is estimated at 1.44 ± 0.09°C (2.60 […]

May 2026 was the 2nd warmest May on record. El Niño has returned and is expected to rapidly strength. There is a ~2.5% chance that 2026 becomes a record warm year, but higher odds of a record annual average in 2027 following El Niño.

March 2026 was the 4th warmest March on record. La Niña has ended and El Niño is expected to return in coming months. There is a 5% chance that 2026 become a record warm year.

February 2026 was the 2nd warmest February on record behind 2024. La Niña is fading and El Niño is expected to return in coming months. There is a 16% chance that 2026 become a record warm 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.

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.

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.

Following the record-smashing summer of 2023, Berkeley Earth’s Zeke Hausfather explores the increasing evidence that global warming has accelerated over the past 15 years in this New York Times Opinion piece.

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, July 2024 was tied for the warmest July since record-keeping began in 1850, continuing a 14-month streak of records. 2024 is now very likely to become the warmest year on record.

Globally, June 2024 was the warmest June since record-keeping began in 1850, continuing a 13-month streak of records. 2024 is now likely 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.
