Today, it’s Midday on the Environment. Last fall, a United Nations climate change report and the U.S. National Climate Assessment estimated that in just 10 years, global warming will begin to trigger changes in the world’s climate that are more severe, more costly and more catastrophic than any we’ve seen thus far.For decades, scientists and activists have been urging the world’s governments to work together to address this global crisis. The U.S. withdrawal last year from the Paris Climate Accord, and the Trump administration’s dismantling of an array of environmental regulations has, in some ways, galvanized the environmental movement to step up its efforts. Earlier this month, freshman Democratic Congresswoman Alexandria Ocasio-Cortez of New York and Democratic Senator Ed Markey of Massachusetts introduced a joint resolution they call the Green New Deal. They describe it as an economic, social and political manifesto for more aggressive steps to mitigate climate change. What is the Green New Deal? Is it the best way to address the climate change crisis? Tom is joined, both in the studio and on the line, by three climate policy experts.
