Climate One is a forum for the discussion of climate change and energy issues that includes a weekly radio show and podcast, as well as social media and blog. It is a division of the Commonwealth Club of California, a public affairs forum based in Northern California.
Climate One also holds live events, which are recorded and distributed to a broad audience. 
Greg Dalton, a former journalist with the Associated Press and other news outlets, is the host of Climate One podcast and radio show and is the moderator of Climate One live events. Dalton has worked with the Commonwealth Club of California for almost two decades. Dalton’s LinkedIn page says the goal of the Climate One discussions are “to change individuals and systems, including energy, transportation, financial, political, health care, psychological, and virtually every other system.” 
Dalton founded Climate One at the Commonwealth Club in 2007. He did so after he traveled to the Russian Arctic for a symposium on global warming with journalists and climate scientists. Now he and his team produce the Climate One radio show that airs on National Public Radio stations across the United States. 
Events and Podcast
Guests on the show have included environmentalist activists Jane Goodall, former Vice President Al Gore, TV host Bill Nye, former “Tea Party” activist Debbie Dooley, and former Google chairman Eric Schmidt; politicians including former Secretary of State Hillary Clinton, former California Gov. Arnold Schwarzenegger (R), and EPA Administrator Andrew Wheeler; and businesspeople including Chevron CEO Dave O’Reilly and Ford Motor Co. chairman Bill Ford. 
Among the live events in 2019 included one at the Harvard School of Public Health in April 2019 with former Obama White House science advisor John Holdren and Obama administration Environmental Protection Agency Administrator Gina McCarthy. 
On one show, titled “The Art of the Green New Deal,” Dalton interviewed Sen. Edward Markey (D-MA) who is the Senate sponsor of the Green New Deal that would remake the entire American economy in areas outside of the environment. He also interviewed Rep. Matt Gaetz (R-FL) who sponsored an alternative “market-based” environmentalist proposal.
