The atmospheric accumulation of carbon dioxide, a greenhouse gas, is the subject of a free public presentation by USGS research scientist Yousif Kharaka at 7 p.m. Thursday, Jan. 27, at USGS in Menlo Park.
The talk will be held in Conference Room A in Building 3 at USGS headquarters, 345 Middlefield Road in Menlo Park.
Humans using fossil fuels pump about 30 billion tons of CO2 into the atmosphere every year, Mr. Kharaka said.
In his talk "Capture and Geologic Sequestration of Carbon Dioxide to Mitigate Global Warming," he will discuss the broad scientific consensus that an excess of CO2 is behind climate change, and that significant challenges will have to be overcome to store this naturally buoyant gas in wells deep underground.
