Living on Earth

Antarctic Ice Missing, Arctic Peatlands Expanding, Nuts to Feed the World and more

Midsummer in the Northern hemisphere marks the dead of winter in Antarctica, usually a time when temperatures plunge and the surrounding ocean ices over, nearly doubling the continent’s size. But this June, scientists found Antarctica’s west coast was missing a chunk of sea ice the size of France. How unusually warm ocean water is affecting sea ice as well as massive Antarctic glaciers. Also, recent findings that peatlands are expanding northward as the Arctic warms might sound like good news, since peat has powerful carbon storage capabilities. But it takes millennia for peat to sequester large amounts of carbon, while we are burning fossil fuels far more quickly than the Earth can absorb. And much of the world’s staple crops of corn, wheat, rice and soy are grown in huge monocultures that disrupt ecosystems and require massive amounts of fertilizer, pesticides, fossil fuels and water. The author of ‘Feed Us with Trees: Nuts and the Future of Food’ offers a more sustainable vision of food production. She shares how nut trees can offer alternative sources of starch, protein and healthy fats that integrate well into local ecosystems and can help feed a growing population. -- Don’t miss the next virtual Living on Earth Book Club event on Tuesday, July 14 at 5 pm PDT / 8 pm EDT!

America’s Enduring Ecology: Forests, Public Lands, and more

As we mark America’s 250th birthday, we celebrate parts of America’s enduring ecology, including our forests, national parks and other public lands. At the heart of one of Washington State’s most expansive wild ecosystems is North Cascades National Park, just a three-hour drive from Seattle yet one of the lesser-known parks.   Also, around 30% of the United States is federal public lands, and the biggest chunk or 245 million acres falls under the purview of the Bureau of Land Management. BLM lands are sometimes called “leftover” or “forgotten” lands, but they offer free or very cheap camping and feature a stark beauty that captivated writer and photographer Josh Jackson, author of the 2025 book, ‘The Enduring Wild: A Journey into California’s Public Lands.’   And when European colonists landed in North America, some of the most dramatic changes they made were to our forests. Clearcutting ran rampant, but now, on the 250th birthday of the United States, much of our forests have recovered, particularly in the Northeast. And today, maintaining our forests is vital for mitigating the effects of climate change. -- Sign up for the next virtual Living on Earth Book Club event on July 14 at 5 pm PDT / 8 pm EDT!

When the Forest Breathes with Suzanne Simard, Ocean Monitoring Restored, Fighting Fracking in Colombia and more.

Forest ecologist Suzanne Simard has shown through her research that the biggest and oldest ‘Mother Trees’ in the forest anchor networks of social connection among the trees, and indeed the whole forest ecosystem. Her latest book is When the Forest Breathes: Renewal and Resilience in the Natural World, and she shares how more sustainable logging practices incorporating Indigenous knowledge can help heal decades of clearcutting harm.   Also, after announcing at the end of May it was dismantling the Ocean Observatories Initiative, the National Science Foundation faced widespread public criticism and the Senate passed a bipartisan measure to preserve the vital ocean monitoring network. NSF then reversed its decision and says an array that was already being removed will be redeployed. We discuss this reprieve for climate and ocean science.   And our sixth and final installment of interviews with the 2026 Goldman Environmental Prize winners features Latin American winner Yuvelis Morales Blanco, honored for fighting against fracking in Colombia and forced to flee after receiving death threats. The recent presidential elections in Colombia put fracking back on the table, after four years of an administration that signaled a desire to transition away from fossil fuels.   --   Sign up for the next virtual Living on Earth Book Club event on July 14 at 5 pm PDT / 8 pm EDT!

How Flowers Made Our World, A Cemetery Buzzing with Bees, El Niño Is Here, and more.

Lush peonies, delicate hydrangeas, and vibrant roses burst into bloom in early summer, filling gardens and parks with color and fragrance. But flowers are more than their beauty. They’re some of the oldest beings on Earth, and they played a large role in shaping the natural world as we know it. Author and biologist David George Haskell joins us to discuss his 2026 book, How Flowers Made Our World: The Story of Nature’s Revolutionaries.   Also, while honeybees get most of the buzz, most bees don’t produce honey, and most don’t even live in colonies. Instead, they’re solitary bees who build individual nests. A recent study details an astonishing finding of several million solitary bees in a cemetery in Ithaca, New York.   And the 2026 El Niño is now officially underway, according to the National Oceanic and Atmospheric Administration or NOAA. Combined with the ongoing rising temperatures from the climate crisis, this possible “super” El Niño could spell major disruption of weather patterns and ocean circulation worldwide.   --   Sign up for the next virtual Living on Earth Book Club event on July 14 at 5 pm PDT / 8 pm EDT!

Juneteenth! Celebrating Black and Brown Stewards of the Green Earth

To celebrate Juneteenth we tell the story of plant biologist Beronda Montgomery. When she sat down to write what became a personal memoir mixed with a botanical history of African Americans, she found her research as a PhD lab scientist had brought her squarely into the world of social science as well. From her studies of how plants respond to light during photosynthesis, she started shining a light on the history of extensive plant cultivation by African Americans, including those who endured forced labor. She joins us to discuss her book When Trees Testify: Science, Wisdom, Historyand America’s Black Botanical Legacy.   Also, George Washington Carver was born into slavery but went on to become a famous agronomist and helped poor people in the South improve their lives and soils by planting peanuts and other legumes. This week, he comes back from the past in the form of actor and playwright Paxton Williams, who joins us as “George Washington Carver” to talk about the future of modern-day agriculture and intersections between racial dynamics and agricultural development. --   Music licensed from Blue Dot Sessions: sessions.blue Learn more about your ad choices.
