El Niño Is Here
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.
A Cemetery Buzzing with Bees
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.
How Flowers Made Our World
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.
When Trees Testify: Science, Wisdom, History and America's Black Botanical Legacy
When plant biologist Beronda Montgomery sat down to write When Trees Testify, 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.
Freedom Trees and The Pecan Master
We continue our chat with Beronda Montgomery about her book, When Trees Testify: Science, Wisdom, History and America’s Black Botanical Legacy. She discusses abolitionist Harriet Tubman’s use of the sycamore tree to help guide enslaved people to freedom, how an enslaved man named Antoine made a breakthrough to graft a successful variety of pecan tree, and the significance of trees as physical companions and powerful metaphors for resilience as we celebrate Juneteenth and remember the end of slavery.
Trump Cuts Ocean Monitoring
The National Science Foundation has announced it will begin removing most of the Ocean Observatories Initiative, a collection of roughly 900 instruments in the Pacific and Atlantic Oceans that gathers fixed-point data on temperature, carbon dioxide levels, and more. The move is part of a broader trend within the current administration to shelve climate science research and reporting.
Seeking Environmental Justice in Papua New Guinea
The indigenous residents of Bougainville island in Papua New Guinea say their home used to provide them with everything they needed—shelter, fertile land, and clean water. That is until a copper and gold mine run by British-Australian company Rio Tinto set up shop and operated in the 1970s and 80s. Today, heavy metals like copper sulfate and cadmium still pollute waterways, and Theonila Roka Matbob, the 2026 Goldman Environmental Prize Winner for Islands and Island Nations, has been fighting for years to pressure Rio Tinto into taking full responsibility for remediating this damage.

Border Wall Threatens Sacred Mountain

As part of its hard line on immigration, the Trump administration is building out new sections of border barriers, and one of the sections recently under construction runs across a small Southern California mountain just east of San Diego called Tecate Peak. KPBS reporter Gustavo Solis says construction crews are destroying parts of a mountain that’s sacred to the Kumeyaay people of California and Baja California.
Note on Emerging Science: Long-Lived Greenland Sharks

With a lifespan of several hundred years, Greenland sharks may be the longest living vertebrates on Earth and are estimated to reach sexual maturity at about 150 years old. Living on Earth’s Don Lyman reports in this note on emerging science about how enhanced activity of DNA repair genes may help Greenland sharks’ eyes avoid the usual degradation of aging.
