California’s water balance, what is left after precipitation runs off, drains and evaporates, is complicated by its diverse geography, ecosystems and microclimates, its wet, cool winters and hot dry summers, and its swings between booms and busts in annual rainfall. Consequently, water in California, is a highly variable and contentious resource that suffers from intense … Continue reading »
In the recent government shutdown, the National Parks were left open to the public while the nearly 20,000 employees and many thousands of volunteers of the National Park Service were sent home. As a result, trash accumulated and toilets overflowed in Yosemite, roads snowed-in at Mt. Rainier, buildings were vandalized in the Great Smoky Mountains, … Continue reading »
UC Berkeley professor David M. Romps co-authored this with two other climate scientists, Peter Kalmus and Kim Cobb. It was first published Dec. 10 as an op-ed in the Washington Post. Romps was one of the two scientists who chose not to attend. This week, more than 20,000 Earth and planetary scientists from all over the world … Continue reading »
I’ve been having nightmares about the sperm whale found on the beach in Indonesia with a stomach full of plastic waste. Sperm whales have the largest brains in existence
Cal students have the power to help lead the nation through the changes needed to tame climate change
Many Community Choice Aggregators are marketing clean energy by simply rearranging where existing low-carbon electricity goes. Change is potentially afoot for me this November, and I’m not talking about the midterm elections. In November, if I do nothing, I will become an electricity customer of East Bay Community Energy. What does that mean? As their … Continue reading »
I am a physicist, and an energy and sustainability science researcher, and live in California because of its penchant for not just setting — but actually achieving big goals and bold visions that others consider too ambitious. What California proposes — we then research, discuss, and accomplish. In fact, we continually exceed the goals that … Continue reading »
The administration’s unprecedented deregulation effort would upend a system that improved air quality throughout the United States and slowed harmful greenhouse gas emissions.
This week, I am very pleased to host two guest voices from the Agroecology Research-Action Collective (ARC). ARC is a new initiative that aims to bring together scholars with frontline farmer and rural groups to advance agroecology and food sovereignty in North America. Recently, two ARC members travelled to the Netherlands to present their research-in-progress … Continue reading »
It’s great to see all these urban farms blossoming across the open lots and schools in the Bay Area. They are producing healthy and tasty lettuce, tomatoes and assorted vegetables for high-end restaurants and local farmer markets. Being close to markets they have a small carbon footprint in transportation costs. And, they are credited for … Continue reading »
California utilities have lost $20 billion in market value since the wildfires began. The horrific wildfires in Northern California’s Wine Country in October and then in Southern California in December killed more than 40 people, burned 1.2 million acres, destroyed thousands of buildings, forced hundreds of thousands to evacuate their homes, and led to deadly … Continue reading »
(Co-authored with Veronica Irastorza, a graduate of UC Berkeley’s Goldman School of Public Policy and former undersecretary of energy in Mexico. Veronica is associate director at NERA Economic Consulting.) The latest good news on renewable electricity generation comes from Mexico, where results were just announced for the country’s third renewables auction for large-scale projects. After average winning … Continue reading »
I thought I knew the answer, but now it’s not so clear. U.S. households and businesses use a whopping 11.5 quadrillion BTUs of energy annually for heating and cooling, about one-third of all residential and commercial energy use. How will this be impacted by global warming? When it comes to electricity, the answer is fairly … Continue reading »
I first encountered the debate on climate change in the 1980s when I helped to organize a workshop at the Beltsville Agricultural Research Center. Our aim was to discuss the findings and implications of emerging research on climate change. As I recall there was not yet a consensus among meteorologists and other scientists about interpreting … Continue reading »
As the price of electric vehicles (EV) has dropped by nearly half the last few years, the number of Californians driving them has gone way up. Almost 300,000 EVs now ply our roadways, up from around 10,000 just five years ago. Every major automaker has now either introduced one or plans to do so soon. … Continue reading »
The problem Houston represents for all of us this week is that we don’t know enough about the impacts that localized, intense rainfall will have on cities.
But we’re learning new things about privacy and emails in the age of FOIA. For many years, I’ve studied environmental and science policy, looking into how governments, industry and NGOs jointly help find ways toward greater sustainability. Most of my work has been on chemical policies and greening chemistry, but in recent years I’ve developed … Continue reading »
Food Evolution is a documentary about GMOs. It is an excellent film that mixes a few compelling stories with interesting interviews that inform viewers without losing their attention. As someone that has worked in agricultural biotechnology for 30 years, I find the contents accurate and insightful.
Driving isn’t what’s causing smog problems — it’s a high load of VOCs
The pope’s encyclical on climate change once again makes headlines as, probably for the first time, it has been presented to President Trump to read. Peter Gleick, president emeritus of the Pacific Institute, Tweeted what I felt when I heard the news: Short as it is, the president will probably not read it. So, Gleick shared a … Continue reading »
