Carbon

Recent data from the Intergovernmental Panel on Climate Change estimate that carbon dioxide (CO2) concentrations in the atmosphere have risen close to 40 percent since before the industrial revolution. The effects of this rise on climate, sea levels and human societies are still being modeled, but one long-standing mystery for scientists has been how plants respond to rising CO2 levels, and how their ability to store the greenhouse gas feeds back into the carbon cycle.

In the small Kern County community of Tupman, the 2013 pistachio harvest is well underway. 

Chris Romanini's family has been farming this land, just west of Interstate 5, where the valley's fields meet the Elk Hills for decades. 

It's probably not the first place you'd think of when it comes to the effort to reduce CO2 emissions and combat global warming. But just a few hundred yards away from this orchard, plans for a $4 billion power plant and fertilizer factory could soon make the Tupman area known for a lot more than those pistachios.
