Today Governor Gavin Newsom signed a historic climate package into law that will ramp up California's action to reduce fossil fuel emissions. The measures require the state to produce 90% of its electricity from clean sources by 2035 and become carbon neutral by 2045.

A plan is being drafted outlining how the state will become carbon neutral.. and to do so all greenhouse gas emissions need to be captured or eliminated.

To discuss further, KCBS Radio news anchor Bret Burkhart spoke with Daniel Kammen, Professor of Energy at UC-Berkeley and former science envoy for the U-S State Department
