Sun sets over sea ice in the Victoria Strait along the Northwest Passage
Researchers look out from the Finnish icebreaker MSV Nordica as the sun sets over sea ice in the Victoria Strait along the Northwest Passage in the Canadian Arctic Archipelago in July 2017. Studies show the Arctic is heating up twice as fast as the rest of the planet. Scientists are concerned because impacts of a warming Arctic may be felt elsewhere.

Climate scientist Katharine Hayhoe is one of the most prominent speakers on climate change, in part because she talks about the importance of communicating with people who don't already agree on the subject.

She's professor and director of the Climate Science Center at Texas Tech University, and at this hour she suggests ways to improve the conversation about climate change.

Also, professor Noah Diffenbaugh of the Woods Institute for the Environment at Stanford University is on the program.

Greg Dalton is the host of the Climate One series for the Commonwealth Club of California.
