US Blocks UN and G20 Climate Action / Not Much Presidential Debate About Climate / USDA Kills Thousands of Beavers / Science at Risk at the Border / HBO's "Ice on Fire" Offers Climate Solutions In this episode, scientists working on the US-Mexico border face unique challenges when trying to study borderlands ecosystems, thanks to everything from outright harassment and profiling, to tight restrictions on what can cross the border. Living on Earth's Bobby Bascomb is producing a series of dispatches from the US-Mexico border and discusses the challenges of doing science on the border. Also, the climate crisis took center stage at two major world meetings in June 2019, but major polluters have yet to step forward with promises to increase their Paris Agreement pledges. The United States remains on the sidelines as President Trump prepares to pull the US out of the Paris climate agreement entirely. Meanwhile, the Earth is warming and changing faster than many climate scientists had predicted, and at times the future looks impossibly grim. But a new HBO documentary called "Ice on Fire" focuses on some solutions already at hand. "Game on" for solving the climate crisis and much more, this week on Living on Earth from PRI.
