California’s Policies Can Significantly Cut Greenhouse Gas Emissions through 2030

A new model of the impact of California’s existing and proposed policies on its greenhouse gas (GHG) reduction goals suggests that the state is on track to meet 2020 goals, and could achieve greater emission reductions by 2030, but the state will need to do more to reach its 2050 climate goals.

Two Berkeley Lab Scientists Named AAAS Fellows

Two Berkeley Lab scientists, climate scientist William Collins and chemist Heinz Frei, have been named Fellows of the American Association for the Advancement of Science (AAAS) for 2014.

New Research Quantifies Health Benefits of Reducing Greenhouse Gas Emissions

Reducing greenhouse gas emissions (GHG), which result from the burning of fossil fuels, also reduces the incidence of health problems from particulate matter in these emissions, according to Berkeley Lab researchers and colleagues. They calculated that the economic benefit of reduced health impacts from GHG reduction strategies in the U.S. range between $6 and $14 billion annually in 2020, depending on how the reductions are accomplished.

As Temperatures Rise, Soil Will Relinquish Less Carbon to the Atmosphere Than Currently Predicted

Today’s climate models probably overestimate the amount of carbon that will be released from soil into the atmosphere as global temperatures rise. The findings are from a new computer model that explores the feedbacks between soil carbon and climate change. It is the first such model to include a realistic representation of microbial interactions.

Lightning Expected to Increase by 50 Percent with Global Warming

Today’s climate models predict a 50 percent increase in lightning strikes across the United States during this century as a result of warming temperatures associated with climate change.

Berkeley Lab on U.S.-China Joint Announcement on Climate Change

On Nov. 11, U.S. President Barack Obama and Chinese President Xi Jinping made a historic U.S.-China Joint Announcement on Climate Change outlining each country’s commitment to strengthen bilateral cooperation on climate change and to announce post-2020 actions in support of the effort to transition to low-carbon economies. Regarding China’s announced target of peaking of carbon

Latest Supercomputers Enable High-Resolution Climate Models, Truer Simulation of Extreme Weather

Not long ago, it would have taken several years to run a high-resolution simulation on a global climate model. But using some of the most powerful supercomputers now available, Berkeley Lab climate scientist Michael Wehner was able to complete a run in just three months. What he found was that not only were the simulations much closer to actual observations, but the high-resolution models were far better at reproducing intense storms, such as hurricanes and cyclones.

Berkeley Lab Scientists ID New Driver Behind Arctic Warming

Scientists have identified a mechanism that could turn out to be a big contributor to warming in the Arctic and melting sea ice. They found that open oceans are much less efficient than sea ice when it comes to emitting in the far-infrared region of the spectrum, a previously unknown phenomenon that is likely contributing to the warming of the polar climate.

New Insights on Carbonic Acid in Water

A new study by Berkeley Lab researchers provides valuable new insight into aqueous carbonic acid with important implications for both geological and biological concerns.

New Project is the ACME of Addressing Climate Change

Eight Department of Energy national laboratories, including Berkeley Lab, are combining forces with the National Center for Atmospheric Research and other institutions in a project called Accelerated Climate Modeling for Energy, or ACME, which is designed to accelerate the development and application of fully coupled, state-of-the-science Earth system models for scientific and energy applications.
