In 2015, Berkeley Lab, UC Berkeley, and Tsinghua University in Beijing formed the Berkeley Tsinghua Joint Research Center on Energy and Climate Change to develop scientifically based clean energy solutions and the next generation of leaders to champion those solutions. Now, that effort has received welcome support from Jim and Marilyn Simons in the amount of a $5 million donation.
Emissions of methane, a potent climate-warming gas, in the San Francisco Bay Area may be roughly twice as high as official estimates, with most of it coming from biological sources, such as landfills, but natural gas leakage also being an important source, according to a new study from Berkeley Lab.
Scientists expect trees will advance upslope as global temperatures increase, shifting the tree line—the mountain zone where trees become smaller and eventually stop growing—to higher elevations. But new research suggests this may not hold true for two subalpine tree species of western North America.
Scientists at Lawrence Berkeley National Laboratory documented a spring pulse in northern Alaska in 2014 that included CO2 emissions equivalent to 46 percent of the net CO2 that is absorbed in the summer months and methane emissions that added 6 percent to summer fluxes. What’s more, recent climate trends may make such emissions more frequent, the scientists conclude.
