After a landmark Supreme Court case that directed EPA to determine whether carbon dioxide and other greenhouse gases endanger public health, the agency found in 2009 that indeed they do. Now, the Trump EPA is attempting to revoke that endangerment finding to unravel all subsequent regulations on tailpipes, smokestacks and more. Vermont Law and Graduate School emeritus Professor Pat Parenteau explains to Host Jenni Doering why this step is just the beginning of what looks to be a long legal fight.

The Trump administration has declared scientists at places like the National Center for Atmospheric Research are promoting ‘climate hysteria’ by overstating the risks to public health and safety, so it’s moving to cut off funds for NCAR. Former TV weatherman Alan Sealls, president of the American Meteorological Society, joins Host Steve Curwood to discuss the important climate and weather modeling NCAR does and how the loss of funding could impact this research.

The warmer winters of climate disruption are bringing shorter and shorter skating seasons on the Rideau Canal in Ottawa, Canada. We head into the Living on Earth archives for a taste of days gone by, when reporter Bob Carty hit the ice to meet locals enjoying the serenity of a skate along the canal.

One of the most heavenly scents on Earth is that of milkweed in bloom, says Living on Earth’s Explorer-in-Residence Mark Seth Lender. But fewer and fewer monarch butterflies are showing up to feed and lay their eggs on this vital plant that gives them a powerful toxic defense against predators.

Monarch butterflies can travel thousands of miles each year between Mexico and North America in an epic relay race of multiple generations. And thanks to new technology, our phones and other Bluetooth devices can now tell us what paths these brave little insects take on this journey. Dan Fagin, who teaches environmental journalism at NYU and is writing a book about monarchs, talks with Host Steve Curwood about the tiny trackers and what it’s like to be among millions of monarchs where they overwinter in Mexico.
