The Pacific Northwest Heatwave in Context

Beginning on June 26th, and lasting for the better part of a week, a massive “heat dome” settled across the Pacific Northwest, creating some of the most extreme heat conditions ever observed in North America. With record-setting temperatures upwards of 40 degrees Celsius above average, this heatwave generated significant global media coverage. Below, Berkeley Earth […]

Global Temperature Report for 2020

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 […]

Berkeley Earth Publishes Detailed Methodology in New Paper

While our fully open-source surface temperature datasets have been publicly available for some time, this paper represents the first time our complete detailed methodology has been formally published. The paper specifically includes discussion of Berkeley Earth’s treatment of air temperature in the Arctic region, and provides visualization of the global warming trends suggested by Berkeley Earth’s dataset vs. other global temperature records.

June 2021 Temperature Update

Globally, June 2021 was the fourth warmest June since record-keeping began in 1850. La Niña has ended, but its lasting impact has contributed to relative coolness in 2021.

March 2021 Temperature Update

Globally, March 2021 was the ninth warmest March since record-keeping began in 1850. Diminishing La Niña conditions have been present in the Pacific and contribute to the relative coolness this year.

January 2021 Temperature Update

Globally, January 2021 was the sixth warmest January since record-keeping began in 1850. Moderate La Niña conditions continue in the Pacific, making it unlikely that 2021 will set a new record for warmest year.

October 2020 Temperature Update

Globally, October 2020 was the fifth warmest October since record-keeping began in 1850. La Niña conditions strengthened in October, significantly reducing the likelihood that 2020 sets a new record for warmest year.
