New Study Provides First Comprehensive Look at Oxygen Loss on Coral Reefs

A new study is providing an unprecedented examination of oxygen loss on coral reefs around the globe under ocean warming. Led by researchers at UC San Diego's Scripps Institution of Oceanography, the study captures the current state of hypoxia—or low oxygen levels—at 32 different sites.

Researchers Extract First Layered Lake-Sediment Sample from Subglacial Antarctica

For the first time, a team of researchers with the National Science Foundation-funded project Subglacial Antarctic Lakes Scientific Access (SALSA) has successfully extracted layered sediments from beneath the modern Antarctic ice sheet.

UC San Diego Leads Sessions on Climate Change, Space, and Neuroscience at SXSW 2023

At the 2023 South by Southwest(SXSW) conference, which runs March 10-14, scientists and leaders from UC San Diego will contribute their expertise to programming on climate change, space, health, and blue technology.

Progress Toward Fast-charging Lithium-metal Batteries

Engineers report progress toward lithium-metal batteries that charge fast – as fast as an hour. This fast charging is thanks to lithium metal crystals that can be seeded and grown quickly into dense layers of uniform lithium metal that lack battery-performance-degrading spikes called dendrites.

Love Your Wetlands Day Teams Up With California Volunteers For Community Climate Action Day

California Volunteers, Office of the Governor partnered with the UC San Diego Natural Reserve System on annual Love Your Wetlands Day to promote a countywide day of service to fight climate change.

SalpPOOP Study Highlights Biogeochemical Importance of Zooplankton Fecal Pellets

New research links fivefold increases in carbon absorption to salp prevalence in the uppermost reaches of the ocean. It is thus a key natural process that mitigates the effects of fossil fuel use and other activities contributing to climate change.

Probing Antarctica by Land, Sea, Air, and from Earth Orbit

More than half a dozen scientists from Scripps Oceanography and the Scripps Polar Center will be venturing to Antarctica for the 2022-23 field season.

Climate Change Exacerbating Gastrointestinal Problems in Children

Researchers at UC San Diego report that “precipitation shocks,” whether droughts or flood-causing rains, can increase rates of diarrheal diseases among children in tropical low-to- middle-income countries.

Can COP Keep up with an Evolving Climate Effort?

Another United Nations climate conference (COP) has come and gone, leaving the world to scratch its head over what was accomplished. The annual conference has ballooned over the years into a massive climate festival: nearly 50,000 people — an all-time record — taking part.

Researchers Identify Elusive Carbon Dioxide Sensor in Plants that Controls Water Loss

UC San Diego scientists have identified a long-sought carbon dioxide sensor in plants, a discovery that holds implications for trees, crops and wildfires. The researchers found that two proteins work together to form the sensor, which is key for water evaporation, photosynthesis and plant growth.
