A pattern of temperature change emerges from natural climate fluctuations

When comparing model simulations of Earth’s recent warming to real-world observations, differences can arise from several factors, including model errors in the simulated response to increased greenhouse gases and natural fluctuations within the climate system. Natural climate variability, also called internal variability, can change regional and global atmospheric…

Using seismoacoustics to improve explosion monitoring

In a special issue of the Bulletin of the Seismological Society of America, Lawrence Livermore scientists describe recent work in seismoacoustics, an area of research that uses observations of both seismic and low-frequency acoustic waves (infrasound) to differentiate between earthquakes and other shallow underground or surface sources like explosions and volcanoes. Both…

Hard as a rock, LLNL to study geologic hydrogen production

Lawrence Livermore National Laboratory (LLNL) has received $1 million to explore technologies that stimulate hydrogen production from mineral deposits found in the subsurface, including developing our understanding of hydrogen-producing geochemical reactions and how to enhance or control the rate of hydrogen production. The use of hydrogen fuel to offset fossil fuel…

Lawrence Livermore’s popular 'Science on Saturday' lecture series returns to Las Positas College

Lawrence Livermore National Laboratory's (LLNL) popular lecture series, “Science on Saturday,” returns Feb. 3 and runs through Feb. 24. The series offers four different lectures with the theme, “Magic of Materials.” Each lecture is presented by leading LLNL researchers who are joined by high-school science teachers. Below is the schedule of lectures, which can also be…

New analysis outlines national opportunities to remove CO2 at the gigaton scale

Lawrence Livermore National Laboratory (LLNL) researchers, along with scientists from more than a dozen institutions, have completed a first-of-its-kind high-resolution assessment of carbon dioxide (CO2) removal (CDR) in the United States. The report, “Roads to Removal: Options for Carbon Dioxide Removal in the United States,” charts a path for the United States to achieve…

Geophysicist characterizes the earth while forming community at Livermore

Geophysicist Christina “Chris” Morency’s research has led her around the globe to demystify the world beneath our feet. Since arriving at Lawrence Livermore National Laboratory (LLNL) in 2011, she has held leadership roles on numerous research teams and has worked diligently to make Lawrence Livermore a welcoming place for all. Originally from France, Morency said she is …

Record-setting SC23 builds mile-high momentum for exascale computing, AI, and the future of HPC

The crowds returned to SC, and with them came a renewed excitement for the future of high performance computing (HPC). A record number of attendees — more than 14,000 — experts, researchers, vendors and enthusiasts in the field of HPC descended on the Mile High City for the 2023 International Conference for High Performance Computing, Networking, Storage and Analysis,…

Inaugural National Lab Research SLAM showcases early-career researchers

Gathered in the Congressional Auditorium on Wednesday, Nov. 15, 17 early-career researchers used three minutes and a single slide to present their pioneering research during the inaugural National Lab Research SLAM. Representing each of the 17 Department of Energy (DOE) national laboratories, finalists presented in four research categories: Energy Security, National…

LLNL-led SCREAM team clinches inaugural Gordon Bell Prize for climate modeling

A Lawrence Livermore National Laboratory (LLNL)-led effort that performed an unprecedented global climate model simulation on the world’s first exascale supercomputer has won the first-ever Association for Computing Machinery (ACM) Gordon Bell Prize for Climate Modelling, ACM officials announced Thursday. The Simple Cloud Resolving E3SM Atmosphere Model (SCREAM) team, led…

National economy continues to reenergize post-pandemic, while pushing toward a new, decarbonized normal

In 2022, Americans used more renewables to generate electricity than in previous years, according to the most recent energy flowcharts and carbon flowcharts released by Lawrence Livermore National Laboratory (LLNL). The nation used 3% more energy, emitted an additional 96 million tons of CO2, but decreased the carbon intensity of U.S. electricity generation by 3.6%,…

Study confirms age of oldest fossil human footprints in North America

New research reaffirms that human footprints found in White Sands National Park, New Mexico, date to the Last Glacial Maximum, placing humans in North America thousands of years earlier than once thought.
