Berkeley Earth’s open-source air quality data has been featured in National Geographic’s April Issue, highlighting the significance of the health crises created by air pollution and poor air quality. As suppliers of comprehensive air quality data, Berkeley Earth provides not only real-time air quality readings, but also provides historic time-series data at the city and […]
Studies estimate that the impacts of air pollution account for upwards of 5% of annual global GDP, and yet annual funding to address air quality averages around only $30million annually. As April marks the beginning of Earth Month, Berkeley Earth is focusing on the significant role that air quality data and analysis plays in improving […]
Berkeley Earth’s Zeke Hausfather Testifies in Hearing on The Science Behind the Impacts of the Climate Crisis
“In many ways 2020 was the year in which both climate change and the accelerating energy transition became impossible to ignore” Dr. Zeke Hausfather, Written Testimony for Hearing on The Science Behind the Impacts of the Climate Crisis On Friday, March 12th, Berkeley Earth Research Scientist Dr. Zeke Hausfather was invited to serve as an […]
We sit down with social entrepreneur, environmental policy innovator, Berkeley Earth Board Director, and In This Together Co-Founder Bill Shireman to discuss the important role of independent climate science in taking a data-driven approach to climate solutions.
Berkeley Earth released our annual Global Temperature Report for 2020, including findings that 2020 was the second warmest year on record. Thanks to our partners in the media, the independent research, data, and findings we presented in this report have reached an audience of nearly 400 million worldwide. One highlight of our impact: Berkeley Earth’s […]
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.
An earlier version of this article originally appeared on the Asthma Allergies Children website. By Liz Muller As I write this white ash is visible in the polluted San Francisco Bay Area air, wafting down from a smoky orange sky and into our lungs, a dangerous byproduct of wildfires burning more than 3 million acres […]
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 2019. We conclude that 2019 was the second warmest year on Earth since 1850. The global mean temperature in 2019 was colder than 2016, but warmer […]
Horrific Air Pollution in Europe Reaches 7 cigarettes per day equivalent, a pack a day in India and China It’s winter, and that’s the worst air pollution period for Europe and China. The levels over much of the continent are in the unhealthy range. In the figure we show a map of the pollution of […]
2016 was the warmest year since humans began keeping records, by a wide margin. Global average temperatures were extremely hot in the first few months of the year, pushed up by a large El Nino event. Global surface temperatures dropped in the second half of 2016, yet still show a continuation of global warming. The […]
by Zeke Hausfather Air pollution in China is a critical global health problem, responsible for somewhere between 700,000 and 2.2 million premature deaths annually. The largest single contributor to air pollution-related mortality is particulate matter below 2.5 microns in size, or PM2.5. Exposure to PM2.5 has been found to increase the risk of heart attacks, […]
by: Zeke Hausfather, Berkeley Earth email@example.com The relationship between greenhouse gas (GHG) emissions and future warming is complex, depending on the atmospheric lifetime of gases, their radiative forcing, and the thermal inertia of the Earth, particularly our oceans. Many non-CO2 GHGs have shorter atmospheric lifetimes, and the global warming-equivalent values commonly used for analysis of emission […]
On May 1, 2016, a fire began southwest of Fort McMurray, Canada. It swept through the community destroying over 2000 structures. You can read about the latest developments here. Since 2014 Berkeley Earth has been expanding its real time database of air pollution. Our original focus was on China, but we have continued to add other regions of […]
by Richard A. Muller and Elizabeth A. Muller For many people, comparing air pollution to cigarette smoking is more vivid and meaningful than is citing the numbers of yearly deaths. When we published our scientific paper on air pollution in China in August 20151, we were surprised by the attention we got for a quick […]
By Zeke Hausfather In recent weeks we’ve seen a political controversy over NOAA’s adjustments to temperature records, with accusations from some in congress that records are being changed to eliminate a recent slowdown in warming and to lend support to Obama administration climate policies. This makes it sound like the NOAA record is something of […]
Earlier this month the Shenyang EPA reported the worse levels of air pollution since record keeping began: Estimates varied between 1000 and 1400 micrograms per cubic meter of PM2.5— the fine particulate matter that has deadly health consequences. The US embassy in Shenyang reported “off the chart” recordings. In our recent study in PLOS on […]
Over the past few days we have been publishing the first major update of our data since early 2015. The data can be found here on our data page. Given the time of year and the wide ranging discussion about whether or not 2014 was a record year, it seemed a good time to asses […]
As the AP reports Lelieveld has published a paper in Nature on the mortality associated with outdoor air pollution that confirms what BerkeleyEarth found in its study of air pollution in China. By their estimate ~1.357M deaths in China are caused by air pollution. By our estimate there are ~1.6 Million deaths per year in China […]
In our study of air pollution in China, we stumbled upon two extraordinary days. The first, which we initially thought was a fluke, turned out to be a single day when air pollution across China was more extensive than we had seen in a years worth of data. It was a mystery until lead scientist, […]
Can natural gas help us reduce climate change by acting as a bridge fuel away from coal? New research from Berkeley suggests that it can, even if it modestly delays the date at which we switch to renewables. The U.S. is in the midst of a natural gas boom. The combination of horizontal drilling and […]
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 […]
There has been much discussion of temperature adjustment of late in both climate blogs and in the media, but not much background on what specific adjustments are being made, why they are being made, and what effects they have. Adjustments have a big effect on temperature trends in the U.S., and a modest effect on […]
