Ex-NASA Scientist Dr. James Hansen: We Need to Act Now to Preserve Our Planet For Future Generations

As Hurricane Michael barrelled down on Florida, famed climate scientist Dr. James Hansen traveled to Minnesota earlier this week to testify on the imminent danger of climate change. He was supposed to be an expert witness at the trial for the “Valve Turners,” the antipipeline activists who staged an unprecedented coordinated action to shut down the flow of oil from the United States to Canada in 2016. But the judge ruled she would not allow witnesses like Dr. Hansen to testify on the clear and present danger posed by climate change. On Tuesday, valve turner activists Annette Klapstein and Emily Johnston were acquitted. We speak with Hansen in Minneapolis about the Valve Turners, the recent IPCC report about the imminent threat of climate change and what must be done to save the planet from destruction. Hansen is the former top climate scientist at NASA. He is now the director of climate science awareness and solutions at Columbia University’s Earth Institute. We also speak with Klapstein and Johnston.
