In addition to the threat to residential neighborhoods, new research from UC Berkeley School of Public Health and UCLA Fielding School of Public Health suggests sea level rise will expose over 400 industrial facilities and contaminated sites in California, including power plants, refineries, and hazardous waste sites, to increased risk of flooding. Increased flooding can come with risks of contamination releases into nearby communities.

The months-long rainy season, or monsoon, that drenches northwestern Mexico each summer, reaching into Arizona and New Mexico and often as far north as Colorado and Northern California, is unlike any monsoon in the world, according to a new analysis by an earth scientist from the University of California, Berkeley.

When a massive wildfire tears through a landscape, what happens to the animals? In a rare stroke of luck, researchers from the University of California, Berkeley and other universities were able to track a group of black-tailed deer during and after California’s third-largest wildfire, the 2018 Mendocino Complex Fire. The results were published Oct. 28 in the journal Ecology and Evolution.

As the earth’s climate warms, residents of affluent nations will find some relief with air conditioning, but people in lower-income countries may have to pay vastly more for electricity or do without cooling, says a new study co-authored at the University of California, Berkeley.

To learn more about the impact of Hurricane Ida — and how it compares to the impact of Hurricane Katrina 16 years ago — Berkeley News spoke with civil and environmental engineering professor Adda Athanasopoulos-Zekkos, who traveled to Louisiana last week as part of a team of engineers organized by the National Science Foundation’s Geotechnical Extreme Events Reconnaissance (GEER) Association.

In a new study, scientists from the University of California, Berkeley, used data from 1,400 indoor air sensors and even more outdoor air sensors included on the crowdsourced PurpleAir network to find out how well residents of the San Francisco and Los Angeles metropolitan areas were able to protect the air inside their homes on days when the air outside was hazardous.

The White House Office of Science and Technology Policy (OSTP) has appointed University of California, Berkeley, scientist Patrick Gonzalez as assistant director for climate and biodiversity. The OSTP advises the president, vice president and the executive office on the science needed to develop and implement national policies.

Scott Stephens is the senior author of a new study that gathers together decades of research documenting how the return of wildfire has shaped the ecology of Yosemite National Park’s Illilouette Creek Basin and Sequoia and Kings Canyon National Parks’ Sugarloaf Creek Basin since the parks adopted policies for the basins to allow lightning-ignited fires to burn.

To meet the development needs of a growing population, Africa’s electricity sector requires a major transformation. New research, co-authored at the UC Berkeley Goldman School of Public Policy, identifies five sets of complementary actions to put Africa’s electricity sector on track to sharply increase electrification rates and secure long-term access to affordable and cleaner energy.

Our understanding, planning, and response to wildfires benefit from connections with data and computing sciences. Recent developments in machine learning and simulations can help first responders detect fires earlier, predict fires’ paths and limit blazes quickly. Through collaborations with practitioners in other fields like microbiology and forest management, these tools are answering previously intractable questions about fires that can inform policy and practice. 

For more than a decade, Joel Moskowitz, a researcher in the School of Public Health at UC Berkeley and director of Berkeley’s Center for Family and Community Health, has been on a quest to prove that radiation from cellphones is unsafe. But, he said, most people don’t want to hear it.

For reasons unknown, Earth’s solid-iron inner core is growing faster on one side than the other, and it has been ever since it started to freeze out from molten iron more than half a billion years ago, according to a new study by seismologists at the University of California, Berkeley.

Forests’ ability to survive and adapt to the disruptions wrought by climate change may depend, in part, on the eddies and swirls of global wind currents, suggests a new study by researchers at the University of California, Berkeley. The findings are the first to show that wind may not only influence the spread of an individual tree or species’ genes, but can also help shape genetic diversity and direct the flow of gene variants across entire forests and landscapes.

What is the cost of one ton of a greenhouse gas? When a climate-warming gas such as carbon dioxide or methane is emitted into the atmosphere, its impacts may be felt years and even decades into the future – in the form of rising sea levels, changes in agricultural productivity, or more extreme weather events, such as droughts, floods, and heat waves. Those impacts are quantified in a metric called the “social cost of carbon,” considered a vital tool for making sound and efficient climate policies. Now a new study by a team including researchers from Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley reports that the social cost of methane – a greenhouse gas that is 30 times as potent as carbon dioxide in its ability to trap heat – varies by as much as an order of magnitude between industrialized and developing regions of the world.

Wildfire smoke can trigger a host of respiratory and cardiovascular symptoms, ranging from a runny nose and cough to a potentially life-threatening heart attack or stroke. A new study suggests that the dangers posed by wildfire smoke may also extend to the largest organ in the human body and our first line of defense against outside threat: the skin.
