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.”

Geoffrey Duffy is a emeritus professor of chemical engineering at the University of Auckland.
He is also the owner and operator of Fibre Dynamics Ltd, a consulting and marketing company specializing in infrared drying and fluid mechanics problems.
Duffy has written numerous articles for Climate Realists, a website that promotes the views of New Zealand climate change skeptics.
Stance on Climate Change
“It is also interesting to note that NASA’s Aqua satellite system has shown that the earth has been cooling since 1998. This corresponds with measurements from the Argos sub-ocean probes that the ocean is cooling. This is in stark contrast with the proposals from many 'climate alarmists'…
“So what are the key players in 'Climate Change'? The major driver is the sun. Warming depends on the sun. Cooling is due to the lack of sun’s energy.” 
“Even doubling our tripling the amount of carbon dioxide will virtually have little impact, as water vapor and water condensed on particles as clouds dominate the worldwide scene and always will.” 
“Climate and local weather is forever changing. Sure we must minimize pollution of our air and water systems with obnoxious chemical and particulates, and not treat them as 'sewers'. But even doubling or trebling the amount of carbon dioxide will virtually have little impact, as water vapour and water condensed on particles as clouds dominate the worldwide scene and always will.” 
“Climate has forever been changing and will continue to do so. The major driver is the sun and the radiation from it. The main atmospheric 'intermediary' between the sun and earth is water, and thus it dictates the behaviour of the earth's climate.” 
Duffy is one of a list of “climate experts” who signed the Manhattan Declaration of Climate Change. The declaration was put forward by the International Climate Science Coalition (ICSC) at the Heartland Institute's 2008 International Conference on Climate Change.
He is also listed as a “registered endorser” of the ICSC's “Climate Scientists' Register” which describes its mission to have “the vast majority of the public come to regard human caused climate catastrophe concerns as unfounded.”
