Hurricane risk perception drops after storms hit

Programs and policies that help households go beyond stocking up on food and medical supplies to invest in longer-term protections could overcome the risk perception gap and support adaptation to rising climate-related threats.

Can alternative meat compete?

The analysis compares innovations and policies related to plant-based and lab-grown alternatives to animal meat and dairy in the U.S. and European Union. Its findings could help ensure legislation levels the food industry playing field.

Moving communities to safety

As sea levels rise and flooding becomes more frequent, many countries are considering a controversial strategy: relocation of communities. A Stanford analysis of planned relocations around the world reveals a blueprint for positive outcomes.

Cooking on gas stoves emits benzene

About 47 million homes use natural gas or propane-burning cooktops and ovens. Stanford researchers found that cooking with gas stoves can raise indoor levels of the carcinogen benzene above those found in secondhand smoke.

A fix for snowpack’s influence on groundwater readings

Scientists have long suspected that the weight of snow and ice in nearby mountains could throw off groundwater assessments tied to elevation changes in California’s Central Valley, but they lacked a way to quantify the effect. A new study demonstrates a solution.

Oil-sand wastewater triggered large Alberta earthquake

New research reveals wastewater injected underground by fossil fuel operators caused a magnitude 5.6 earthquake in November 2022 in the Peace River area of Alberta’s oil sands region. This is the first study to link seismicity in the area to human activity.

Zombie forests

The researchers created maps showing where warmer weather has left trees in conditions that don’t suit them, making them more prone to being replaced by other species. The findings could help inform long-term wildfire and ecosystem management in these “zombie forests.”

A new chance to protect wetlands

New analysis shows the U.S. has accounted for more wetland conversion and degradation than any other country. Its findings help better explain the causes and impacts of such losses and inform protection and restoration of wetlands.

Rethinking meat substitutes

Plant-based and lab-grown meat substitutes are here to stay, but are unlikely to eliminate livestock agriculture’s climate and land use impacts anytime soon, according to Stanford environmental scientist David Lobell.

Volcano detective

As a young adult, Ayla Pamukçu found herself at a crossroads between college and culinary school. Thanks in part to an influential box of rocks, she chose a research path that eventually led to a career studying the inner workings of the Earth.

Beaver dams buffer rivers against climate extremes

American beaver populations are booming in the western United States as conditions grow hotter and drier. New research shows their prolific dam building benefits river water quality so much, it outweighs the damaging influence of climate-driven droughts.

Cover crops can lower yields

Federal subsidies promote planting cover crops to store carbon in agricultural soils, among other benefits, but the approach as currently practiced can reduce yields in the U.S. Corn Belt, researchers find. Their analysis highlights the need to better implement the practice.

Wildfire smoke exposure hurts learning outcomes

Pollution from wildfires is linked to lower test scores and possibly lower future earnings for kids growing up with more smoke days at school, a new study finds. Impacts of smoke exposure on earnings are disproportionately borne by economically disadvantaged communities of color.

Wildfire smoke is unraveling decades of air quality gains

Stanford researchers have developed an AI model for predicting dangerous particle pollution to help track the American West’s rapidly worsening wildfire smoke. The detailed results show millions of Americans are routinely exposed to pollution at levels rarely seen just a decade ago.

Are we missing a crucial component of sea-level rise?

Across Antarctica, some parts of the base of the ice sheet are frozen, while others are thawed. Scientists show that if some currently frozen areas were also to thaw, it could increase ice loss from glaciers that are not currently major sea-level contributors.

New ‘lab on a chip’ may accelerate carbon storage efforts

A tiny new device allows scientists to directly observe and quantify how rocks change in the presence of acids, enabling more accurate assessments of sites for underground storage of carbon dioxide, hydrogen, and industrial waste.

Geological activity can rapidly change deep microbial communities

New research reveals that, rather than being influenced only by environmental conditions, deep subsurface microbial communities can transform because of geological movements. The findings advance our understanding of subsurface microorganisms, which comprise up to half of all living material on the planet.

When will California’s San Joaquin Valley stop sinking?

A Stanford University study simulates 65 years of land subsidence, or sinking, caused by groundwater depletion in California’s San Joaquin Valley. The results suggest significant sinking may continue for centuries after water levels stop declining but could slow within a few years if aquifers recover.

Pollution and crops

New analysis shows crop yields could increase by about 25% in China and up to 10% in other parts of the world if emissions of a common air pollutant decreased by about half.

Scientists model landscape formation on Titan

A new hypothesis reveals that a global sedimentary cycle driven by seasons could explain the formation of landscapes on Saturn’s moon Titan. The research shows the alien world may be more Earth-like than previously thought.

Stanford’s Richard Nevle discusses his new book

Richard Nevle, deputy director of Stanford’s Earth Systems Program, discusses his forthcoming collection of essays about the Sierra Nevada mountain range, The Paradise Notebooks.

Health, happiness and prosperity – with fewer kilowatts

Analysis of data from 140 countries suggests many rich countries could use less energy per capita without compromising health, happiness or prosperity. Countries struggling with energy poverty may be able to maximize well-being with less energy than previously thought.

Stanford energy expert discusses UN climate report

Energy expert Inês Azevedo, a lead author of the energy chapter in the United Nations’ new report on climate mitigation, discusses the assessment and changes necessary to keep global warming below 2 degrees Celsius.

Personal experience and disaster adaptation

Surveys of people exposed to wildfires and hurricanes show that negative experiences with these events are associated with elevated perceived risk for specific climate hazards and self-reported adaptation behaviors, as well as increased support for interventions. The findings could help shape public communications and policy.

New model may improve Bay Area seismic hazard maps

Using the Santa Cruz Mountains as a natural laboratory, researchers have built a 3D tectonic model that clarifies the link between earthquakes and mountain building along the San Andreas fault for the first time. The findings may be used to improve seismic hazard maps of the Bay Area.
