350.org Founder McKibben Discusses Significance Of Record Atmospheric Carbon Levels
Bill McKibben has been sounding the alarm about human-caused climate change for more than 30 years. He is the founder of the seminal environmental group 350.org, so named because 350 parts per million is considered the safe concentration of carbon dioxide in the atmosphere.
This week concentration of carbon dioxide in the atmosphere has surpassed 415 parts per million. It's the highest level recorded in human history. Temperatures in the Arctic were in the mid-80s this week.
McKibben has a new book out called, “Falter: Has the Human Game Begun to Play Itself Out?”
As part of coverage from the KPBS Climate Change Desk, McKibben joins Midday Edition Wednesday to talk about the significance of surpassing 415 parts carbon dioxide per million in the earth's atmosphere.
