As part of an experiment to measure gases and particles from brakes and tires, AirUCI faculty Don Blake has been using his truck as a scientific apparatus.  This was the second time he has driven the truck while riding the brakes, and the results have been surprisingly effective.  The experiment is part of the Beyond the Tailpipe group's collaborative research projects into this little understood area of air pollution.  Read the article     Learn more about Beyond the Tailpipe

AirUCI faculty Annmarie Carlton, currently serving a year in the White House as a Revelle Fellow, was the guest on the November 29th UCI Podcast which was recorded before her departure to Washington D.C.  Annmarie discusses her research and background, airborne particles, climate change, and the challenges of science influencing policy at both small and large scales.  Hear the podcast

A paper published by AirUCI faculty James Randerson and his team describes how Sierra Nevada wildfires could increase in number by 20 percent or more by the 2040s, and that the total burned area could increase by about 25 percent.  The findings “show how short events like heat waves impact fires,” said Aurora Gutierrez, project specialist in the Randerson group and lead author on the paper.  “What makes this novel is that we were trying to identify the role of individual temperature extremes on individual dates,” said Jim.  Read the article

An article written by AirUCI faculty Jun Wu describes the variety of health risks exacerbated by climate change and associated environmental justice issues.  Extreme heat, more frequent and extreme weather events, and rising sea levels all combine to degrade air and water quality, threaten food supplies, and displace millions of people.  Along with AirUCI research specialist Shahir Masri in her group, Jun studied the effects of wildfires on different populations and further found that elderly and low-income residents suffered a disproportionate share of the fires’ impacts.  Read the article

AirUCI faculty Steve Davis is co-author on a paper published in Nature Communications that describes how wind and solar energy could meet as much as 94% of demand for electricity in the 42 major countries they studied.  “Wind and solar could meet more than 80 percent of demand in many places without crazy amounts of storage or excess generating capacity, which is the critical point,” said Steve.  With the addition of 12 hours of energy storage capacity, systems become dominated by solar power and can satisfy demand 83 to 94 percent of hours.  Read the article

An article describing the activities of AirUCI faculty Annmarie Carlton during her year as a science advisor in the White House reveals her motivation and dedication.  The environmental issues on which she offers expertise are broad based and urgent, and she compares today's threats to some others in past years which have largely been solved.  Read the article

AirUCI faculty Steve Davis was interviewed for WSJM radio about his recent study investigating the costs of wildfires that was published in the journal Nature Sustainability.  His team found the cost of the 2018 wildfire season to have totaled about $150 billion in losses, amounting to .7 percent of the gross domestic product of the U.S.  As Steve said, “If we continue to have these kinds of wildfire seasons, the costs are going to maintain themselves.”  Read the story

AirUCI co-Director Barbara Finlayson-Pitts is profiled in an article describing how her research group is working to understand how air pollution evolves in the atmosphere.  One project studies how sulfur-containing pollutants — generated by both man-made and biological processes — contribute to the formation of smog, then go on to generate secondary compounds in our air.  Read the article

Mike Dennin, AirUCI faculty and dean of undergraduate education, has been elected as a fellow to the American Physical Society.  The election committee cited not only his research in physics, but his extensive and creative outreach that strives to popularize science in the mainstream media.  Read the announcement

AirUCI faculty Steven Davis is quoted in a Phys.Org article on the increase of CO2 emissions worldwide as the Covid pandemic has eased.  "Our results show that the pandemic-related decrease in global emissions is mostly over, but also that the rebound in economic activity and emissions has been quite uneven across the world," said Steve. "Despite hopes that targeted stimulus could boost shares of renewable energy, increases in energy use have outpaced 'building back better.'"  Read the article
