California Governor Jerry Brown used the occasion of his fourth inaugural address to propose an ambitious new clean energy target for the state: 50% renewable energy by 2030.
“We are at a crossroads,” Brown said in announcing the proposal, according to Climate Progress. “The challenge is to build for the future, not steal from it, to live within our means and to keep California ever golden and creative.”

Paul C. (“Chip”) Knappenberger is the Administrator of the World Climate Report, a blog published by New Hope Environmental Services, “an advocacy science consulting firm” run by global warming skeptic, Patrick J. Michaels.
Stance on Climate Change
“The fact of the matter is that there does exist a growing body of scientific evidence that the climate changes in the coming decades will be modest and proceed at a rate that will lie somewhere near the low end of the IPCC projected temperature range.” 
“…the warming that appears in the compiled temperature history of the state [Utah] may not be evidence of regional (or larger-scale) climate change, but instead may be caused by non-climatic influences on the local thermometers.” 
“There is still a general lack of evidence that shows a statistically significant relationship between anthropogenic climate change and weather-related damage…”

According to MasterResource, Knappenberger has authored or co-authored over 20 papers “appearing in the peer-reviewed scientific literature,” and others in scientific conference proceedings, professional journals, and the press.
Many of his papers were co-authored with fellow skeptic Patrick J. Michaels, and some are published by conservative think-tanks such as the Cato Institute and the Science and Public Policy Institute (SPPI). Some of Knappenberger's scientific articles have been debunked by DeepClimate.
