Living on Earth

When the US Supreme Court set Monday, October 5th for oral arguments on an appeal from the Colorado State Supreme Court by Suncor and Exxon, it highlighted what could become a landmark case about damage from climate change and the role of fossil fuels. Why the case could make or break the ability of states and local governments to ‘make polluters pay.’   Also, our brightly lit modern world is increasingly drowning out the stars. To rediscover what we miss when we can’t look up and see the heavens in their full glory, award-winning author Craig Childs embarked on a journey by bike from blindingly bright Las Vegas into the dark skies of the remote Nevada desert. His 2025 book is The Wild Dark: Finding the Night Sky in the Age of Light.   And much is at stake for the climate and environmental protection when it comes to this fall’s Congressional and Senate races, in the middle of the second Trump presidency. But the often-overlooked elections for state legislatures and governors can also go a long way towards shaping the future of these issues, and we discuss a few key states to watch. --- We want to hear from you!

After the deadly floods in Nepal this August, researchers rapidly assessed the event and concluded that climate change played a “very strong” role in the catastrophic glacial collapse. We discuss the human toll of the floods and the moral duty of the world to slow the climate crisis and help Nepal adapt.   Also, the 2026 United Nations Climate Summit and Climate Week, which just wrapped up in New York City, took place in the wake of a summer marked by deadly extreme heat, the Nepal flood disaster and a UN report on the inevitable “overshoot” of the 1.5 degree C warming goal. We talk about the disjoint between urgent warnings and pleas for help from vulnerable nations, while countries like the US continue boosting fossil fuels -- amid the rapid growth and cost savings of renewable energy. And a recent study in the journal Scientific Data shows that since 1979, around 12.5 trillion tons of ice have melted from glaciers in Greenland and Antarctica -- enough to cover the entire US in 5 feet of ice. And the melting has been speeding up in the last two decades. We discuss the implications for future melting and global sea level rise. Plus: In addition to storing carbon through photosynthesis, trees have another carbon cycle trick up their sleeve, or rather, bark, and it's been hiding in plain sight. Scientists have discovered that tree bark hosts millions of microbes involved in consuming and producing methane, a powerful greenhouse gas. Learn more about your ad choices.

2026 was recorded as one of the hottest summers globally, with deadly heatwaves in Europe and catastrophic floods in Nepal. We discuss how the United Nations put out a report warning that current climate policies will lead to at least 1.8°C of global temperature increase, well beyond the 1.5°C goal of the Paris Agreement raising the alarm on global temperature rise. Also, California is reducing its natural gas consumption by increasing its solar energy battery energy storage and utility scale solar systems. Compared to the rest of the nation, in 2014 the state was producing 10 percent of the country’s total gas-fired electricity, but by 2025 it was down to just 4 percent. And Trees provide us with shade, food, beauty and of course, oxygen to breathe. They often outlive humans, and can teach us about life, aging, and how to be better stewards of the earth. We talk about Robert Moor’s newest book “In Trees: An Exploration”. Learn more about your ad choices. Visit megaphone.fm/adchoices

The devastating August 2026 flash floods in Nepal and Tibet were triggered in part by a glacial collapse, a phenomenon likely to become more frequent as the Earth continues to rapidly warm due to human caused climate change. We discuss why climate change is making mountains and glaciers more unstable, and how early warning systems and less development in floodplains could prevent future loss of life.  Also, as global sea temperatures rise due to climate change, coral reefs around the world are struggling through mass bleaching events. But new research has identified nearly one-third of the world’s coral reefs as climate-resilient “super reefs”, three times more than was previously estimated.  And inspired by the popular Fat Bear Week, researchers with the Marmot Project launched Fat Marmot Week this year to raise awareness of these large ground squirrels, and drum up support for sustaining their decades-long research project. We talk about the winner of Fat Marmot Week, and other creative ways the team is fundraising and spreading a love of yellow-bellied marmots. Learn more about your ad choices.

Great Britain is Europe’s third largest oil and gas producer, even with a commitment to a net-zero economy by 2050. A small group of climate activists is helping the UK meet that target by winning a Supreme Court decision that’s blocking any new UK oil and gas projects that don’t assess climate impacts. Sarah Finch of Surrey, near London led the fight against proposed oil and gas drilling in the region known as the Weald, and she’s been recognized with the 2026 Goldman Environmental Prize for Europe.  Also, efforts to bring back bison that once roamed the Great Plains are helping to revive Indigenous culture on lands across the US West, including in the city of Denver. And the Utah desert with its raw beauty has long been a muse for writer Terry Tempest Williams. In her 2026 book, The Glorians: Visitations from the Holy Ordinary, she explores miraculous moments of grace that call for our attention, even in spaces that may at first seem unremarkable. Terry joined us for an online Living on Earth Book Club event. --  Find photos, transcripts, links to more information about these stories, and much more at the Living on Earth website, loe dot org!  Learn more about your ad choices.
