We’ve all seen the images of huge icebergs breaking off the Antarctic ice sheets into the ocean. It’s not just polar bears and penguins who are in danger of losing their habitat. Our “pale blue dot” in the universe as Carl Sagan described Earth, is in peril. The top scientists of the UN Intergovernmental Panel on Climate Change say we have only until 2030 to “avoid catastrophic environmental breakdown.” Young people see their future fraught with risk. And they are stepping up and speaking out. Sixteen-year-old Greta Thunberg of Sweden began a school strike protesting the lack of urgency in addressing climate chaos. Her action caught on and spread all over the world. New groups of climate activists such as 350.org, Extinction Rebellion and the Sunrise Movement have arisen. They are demanding radical change in business as usual. Interviewed by David Barsamian. Recorded at KGNU.
