Study: Soils Could Release Much More Carbon Than Expected as Climate Warms

Scientists working in Blodgett Forest

Soils could release much more CO2 than expected into the atmosphere as the climate warms, according to new research by scientists in EESA's Climate and Ecosystems Sciences Division—Caitlin Hicks Pries, Christina Castanha, Rachel Porras, and Margaret Torn.

Torn and Vaughn Contribute to New Soil Carbon Study

Soil excavation

Margaret Torn and Lydia Vaughn (picture not available) of the Climate & Ecosystem Sciences Division contributed to a paper in the journal Science that found that soil will absorb far less atmospheric carbon than expected during the 21st century. The research, led by scientists from UC Irvine, was conducted by adding highly accurate radiocarbon dating…

Airborne Campaign in the Icy Arctic

Gulfstream-159 (G-1) research plane from the ARM Aerial Facility - in flight.

In the News: Sébastien Biraud led an ARM-ACME V team through a 16-week airborne campaign to collect data over the tundra of Alaska’s North Slope. The team flew 38 flights, just 500 feet above ground, from June 1 to September 15, using a Gulfstream-159 (G-1) research aircraft from the ARM Aerial Facility. Most flights went over…

New Research: Feedback between Permafrost Carbon and Climate

Image of journal cover

Charlie Koven, scientist in Climate and Ecosystem Sciences Division, discusses newly published research results in LBNL’s News Center today. As global warming causes soil temperatures to increase, some of the billions of tons of carbon frozen in Arctic permafrost will will be released into the atmosphere, and accelerate climate change. This is a big unknown. Now there’s a…
