Berkeley Earth Global Temperature Update: 2020 Was Second Warmest Year Since 1850 Berkeley, Calif. — Berkeley Earth today released its Global Temperature Report for 2020, concluding that the year was nominally the second warmest on Earth since 1850 based on land and ocean data. Globally, 2020 was slightly cooler than and nearly tied with 2016. […]

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.

As an eventful year of climate news comes to a close, Berkeley Earth climate scientists Dr. Robert Rohde and Dr. Zeke Hausfather talk with Social Media Manager Kari Hulac about air surface temperature records and the significant warming event in the Arctic region, as well as preview some exciting new research about climate change mitigation efforts.

Congratulations are in order for Berkeley Earth’s sister organization Deep Isolation, who announced today the closing of a $20m Series A funding round, led by nuclear industry leaders NAC International. Founded by Berkeley Earth Co-Founder and President Elizabeth Muller, Deep Isolation is developing a patented process to safely dispose of nuclear waste, a major issue […]

In this midst of a record-setting fire season, Berkeley Earth’s climate scientists Robert Rhode and Zeke Hausfather talk with Social Media Manager Kari Hulac to discuss climate change and the fires burning across the West.

Warming weather is unlikely to stop the spread of the pandemic. Warm, sunny weather may have some limited impact on the rate of spread, but in the absence of strong interventions, the pandemic is likely to continue spreading through the summer months in most parts of the world.

Mountains of ink have been spilled in recent years on whether or not global warming has paused or slowed down. We’ve discussed it extensively in the past, and numerous studies have examined whether the apparent pause might have been caused by additional ocean heat uptake, small volcanoes, a weak solar cycle, poor arctic coverage in existing datasets, and\or a […]
