http://democracynow.org - To mark the 100th day of Donald Trump’s presidency, thousands of climate activists from around the country are converging in Washington, D.C. on Saturday for the People’s Climate March. Already, Trump has threatened to pull the U.S. out of the Paris climate accord, begun dismantling President Obama’s climate legacy and revived the Keystone XL and Dakota Access pipelines. He has also put climate change deniers in charge of several key agencies, including the Environmental Protection Agency, and proposed slashing the budget of the EPA and other climate programs. This comes as scientists have confirmed 2016 was the warmest year on record. Our guest is Bill McKibben, co-founder of 350.org, who helped organize this latest march and notes: "Weekends are for fighting tyranny."
