Using a novel homogenized daily temperature record from Berkeley Earth, the first of its kind, Hausfather’s presentation will outline findings that more maximum daily temperature records have been set in the last decade than previously reported.

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, […]
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.
