A New Species in the Amazon Rain Forest – Scientists

February 27, 2014

The Amazon Basin in South America includes the most biodiverse tract of tropical rainforest on the planet, covering 5.5 million square kilometers. Due to the sheer size of  the Amazon rainforest, the area has a strong impact on the climate in the Southern Hemisphere and is a primary driver of global atmospheric circulation. Berkeley Lab researchers joined Energy Department (DOE) officials and scientific collaborators from the United States, Brazil, and Germany, last week in Brazil to open a two-year field study in the Amazon Basin.

Berkeley Lab Climate Scientists See Better Climate Models, Warmer Future

September 27, 2013

Michael Wehner, a climate scientist in Berkeley Lab’s Computational Research Division, and William Collins, head of the Lab’s Climate Sciences Department, were lead authors on the IPCC report’s chapters on long-term climate change projections and climate models, respectively. They are among more than 200 lead authors from more than 30 countries in IPCC’s Working Group I. Their report released today provides a comprehensive assessment of the physical science basis of climate change.

JBEI Technoeconomic Model: The Sequels

September 9, 2013

JBEI researchers are developing wiki-based technoeconomic models to help accelerate the development of next generation biofuels that are economically competitive with petroleum-based fuels.

Biological Soil Crust Secrets Uncovered

June 14, 2013

A team of Berkeley Lab researchers has performed molecular level analysis of desert biological soil crusts – living ground cover formed by microbial communities – to reveal how long-dormant cyanobacteria become activated by rainfall then resume dormancy when the precipitation stops.

New Study: As Climate Changes, Boreal Forests to Shift North and Relinquish More Carbon Than Expected

May 5, 2013

New Berkeley Lab research maps how Earth’s myriad climates—and the ecosystems that depend on them—will move from one area to another as global temperatures rise. The approach foresees big changes for one of the planet’s great carbon sponges. Boreal forests will likely shift north at a steady clip this century. Along the way, the vegetation will relinquish more trapped carbon than most current climate models predict.

Meeting the Computing Challenges of Next-Generation Climate Models

March 26, 2013

Berkeley Lab recently hosted an international workshop that brought together top climatologists, computer scientists and engineers from Japan and the United States to exchange ideas for the next generation of climate models as well as the hyper-performance computing environments that will be needed to process the data from those models. It was the 15th in a series of such workshops that have been taking place around the world since 1999.

The Science of Clouds—Why They Matter, and Why There May be Fewer of Them

March 13, 2013

Clouds can both cool the planet, by acting as a shield against the sun, and warm the planet, by trapping heat. But why do clouds behave the way they do? And how will a warming planet affect the cloud cover? Lawrence Berkeley National Laboratory scientist David Romps has made it his mission to answer these questions.

New Research Will Help Shed Light on Role of Amazon Forests in Global Carbon Cycle

January 28, 2013

Scientist Jeffrey Chambers and colleagues at Berkeley Lab have devised an analytical method that combines satellite images, simulation modeling and painstaking fieldwork to help researchers detect forest mortality patterns and trends. This new tool will enhance understanding of the role of forests in carbon sequestration and the impact of climate change on such disturbances.

A New Way to Study Permafrost Soil, Above and Below Ground

January 3, 2013

A group of researchers that includes scientists from Berkeley Lab have developed a new way to explore the little-known world of permafrost soils, which store almost as much carbon as the rest of the world’s soils and about twice as much as is in the atmosphere. The new approach combines several remote-sensing tools to study the Arctic landscape, above and below ground, in high resolution and over large spatial scales.

New map shows global reach of Berkeley Lab’s geologic carbon sequestration research

December 20, 2012

At the southern tip of Australia, Berkeley Lab scientists are helping to verify that depleted natural gas reservoirs can be repurposed for use as geologic carbon sequestration sites.
In Mississippi, they’re exploring whether it’s possible to produce electricity from the Earth’s heat using CO2, as well as store some of the CO2 permanently underground.
Many other geologic [...]
