EESA Scientists Are First to Directly Measure Methane’s Increasing Greenhouse Effect at the Earth’s Surface

Scientists have directly measured the increasing greenhouse effect of methane at the Earth’s surface for the first time. A research team from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) tracked a rise in the warming effect of methane — one of the most important greenhouse gases for the Earth’s atmosphere — over a…

Berkeley Lab Researchers Use Remote Sensing Techniques to Assess Hurricane Impact on Trees

Building on methods they used to assess the impact of hurricanes such as Katrina, Gustav, and Rita on forests and tree mortality, scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have produced a rapid mapping of the disturbance intensity across Puerto Rico’s forests with the help of Google Earth Engine.

EESA Leads Development of New-Generation Soil Carbon Model

There may be a more direct way to estimate the amount of carbon that exists within soil due to expected changes in climate, according to new research. Scientists use mathematical models that evaluate the carbon content of soils to predict how global change affects the amount of carbon released from soil into the atmosphere as…

EESA Climate Scientist Featured on KQED Forum Radio Show

Travis O'Brien

The high temperatures that hit the San Francisco Bay Area during the week of June 18 got a lot of residents thinking about warm weather. And with many cities hitting triple digits, many locals, no doubt, were wondering how to handle extreme heat in the future. By the end of the week, Travis O’Brien, a climate scientist with…

Robinson Negrón-Juárez, Charles Koven, William Riley, Ryan Knox, and Jeff Chambers, researchers in EESA and CESD, published a letter in Environmental Research Letters showing that most earth system models (ESM) overpredict tropical forest biomass in response to increased forest productivity. In contrast, observations show that as tropical forest productivity increases, trees do not continue to store CO2 at…
