Living on 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 Bl...

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.

Also, today the Agora and Acropolis of Athens, Delphi on Mount Parnassus, and other Greek archaeological sites preserve not only cultural heritage, but also animal and plant species, including some that were around in ancient times and are d...

More than two-thirds of U.N. members recently voted in favor of a resolution affirming a landmark ruling by the International Court of Justice that countries have a legal obligation to limit global warming. While this advisory opinion is not enforceable, it will likely be cited in lawsuits and appeals as a fact in the fight against climate disruption.

Also, the 2026 FIFA Men’s World Cup will mostly take place during the North American summer, and the prospect of extreme heat prompted a group of current and former players to write an open letter to FIF...

Living near more large Concentrated Animal Feeding Operations or CAFOs may raise cancer risk, according to a study from Yale researchers. With thousands of cows, pigs, or chickens packed in small spaces, CAFOs produce a lot of waste that pollutes air and water, which may explain the cancer association, though the study does not prove causation. 

Also, North Atlantic Right whales were once so thoroughly hunted they nearly went extinct. When hunting these mammals was outlawed, they slowly started to bounce back, but today Right whales are dealing with newer deadly threats, such as fishing gea...

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, as China rapidly builds out renewable...

A new “coalition of the willing” to transition away from fossil fuels recently gathered in Colombia, born in part out of frustration over fossil fuel friendly nations like the US, Russia, China, and Saudi Arabia stalling the longtime UN climate process.

Also, the indie-pop band AJR is known for its high-energy anthems and along with growing their fan base of mostly young adults, they’re growing the climate movement. AJR bassist Adam Met joins us to talk about engaging fans to sign petitions, join local groups and, most importantly, vote.

The US Supreme Court recently heard oral arguments for Monsanto v. Durnell, a case about whether states can require warning labels on pesticides if the EPA does not. This stems from thousands of lawsuits against Roundup maker Monsanto, alleging that farmers and landscapers who developed cancer weren’t warned of the risks. Though the World Health organization has classified glyphosate, the key ingredient in Roundup, as “probably carcinogenic”, the EPA has not found glyphosate can cause cancer.

Also, the US-Israel joint war against Iran has shaken global energy markets, closed the Strait of Hormuz and restric...

The US Senate recently voted to reverse a moratorium on mining near the Boundary Waters Canoe Area Wilderness in Minnesota, a million acres on the US-Canada border that’s teeming with wildlife and crystal-clear waters. The region is also rich in valuable copper, nickel, and cobalt, but Sen. Tina Smith (D-MN) says mining in the same watershed as the Boundary Waters poses unacceptable risks.

Also, while electrifying transportation is essential to addressing the climate crisis, the mining of nickel, copper, and lithium required to build out these green technologies brings its own environmental and social cos...

The first Earth Day in 1970, when some 20 million people peacefully demonstrated, arrived amid Vietnam War protests and other social unrest. And it came not long after the Apollo 8 astronauts snapped the iconic “Earthrise” photo that showed all of us were on a single, fragile planet amid the blackness of space. In this moment when humans have finally returned to the Moon after decades, we reflect on the movement that led to that first Earth Day and how the world has changed.

Also, the four astronauts of the Artemis II mission that safely splashed down on April...

About two thirds of the US-Mexico border is along the Rio Grande, and the Trump Administration is working to install hundreds of miles of buoy barriers in the river. Now residents of border towns are raising the alarm over how these buoys could impact wildlife, restrict access to the river and sever cultural ties.

Also, news media outlets are retreating from covering climate change, according to the Media and Climate Change Observatory at the University of Colorado Boulder, which has been tracking this trend for decades. They report that since a peak in 2021, climate news s...

The astronauts of the Artemis II mission are prospecting for a planned base on the moon, the first lunar expedition since 1972. The crew includes the first woman, the first person of color, and first Canadian to travel to the Moon. Danny Olivas, an engineer and retired NASA astronaut, talks about the mission objectives and challenges, why it faced delays and what sets the Artemis program apart from the Apollo visits to the moon of more than 50 years ago.

Also, a panel known as the “God Squad”, consisting mostly of Trump cabinet members, recently voted to exemp...

A federal judge recently issued an enforcement order mandating the release of funds from FEMA's Building Resilient Infrastructure and Communities or BRIC program, which the Trump administration had stalled. Why money spent to protect critical infrastructure from disasters like storms, floods and wildfires pays for itself many times over.

Also, over billions of years of its history, the planet has frozen over almost completely and then lost all its ice as crocodiles basked in a balmy Arctic. Carbon-based life arose and adapted to all this change. And at the center of it all is the n...

The investment giant Vanguard is retreating from its climate initiatives as part of a $30 million settlement deal for an anti-trust lawsuit brought by Republican state attorneys general. The lawsuit alleged that Vanguard and fellow asset managers BlackRock and State Street, which are still fighting the suit, conspired to kill the coal industry. Vanguard did not admit to wrongdoing but is now barred from participating in climate investment watchdog groups such as Ceres.

Also, facing pain at the pump, US drivers looking to buy an electric vehicle now have more and cheaper choices than ever. But w...

A decades-old US Forest Service rule that’s been used to supposedly reduce wildfire risk through large-scale logging while bypassing environmental review has been deemed unlawful by a federal court in Oregon. Clearcutting can instead increase wildfire risk, and our guest says USFS needs to rethink its entire approach to managing forests and wildfire risk.

Also, the Artemis II mission is getting ready to use the most powerful rocket ever built by NASA to return to the moon for the first time since the original Apollo missions more than 50 years ago. How declining public support shu...

Descendants of enslaved people fighting pollution in Louisiana’s ‘Cancer Alley’ have been greenlit for a trial. Their lawsuit alleges the St. James Parish government discriminated against Black residents by repeatedly permitting industrial plants in predominantly Black districts while shielding mostly white districts from industry.

Also, President Trump has deemed glyphosate as essential for national security even though some 200,000 people have complained they have gotten cancer or other adverse health effects, while using it as directed. Meanwhile a Missouri state court has given preliminary approval to a class action settlement plan for people sickened by Roundup...

The Dutch special municipality of Bonaire in the Caribbean is already experiencing dangerous heat and could see a fifth of its land disappear under rising seas by 2100. But the Netherlands is discriminating against these overseas citizens by failing to adequately reduce global warming emissions and develop adaptation plans to help them cope, according to a January 2026 Dutch court decision.

Also, poet and author Jason Allen-Paisant left his native Jamaica to gain a graduate school education and prize-winning poetry career in England and France. He now looks back with wonder at the green of Jamaica where g...

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, setting up what looks to be a long legal fight.

The Trump administration has also 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 fun...

The ongoing efforts of the Trump Administration to walk back climate policy and clean energy development may be handing over the health of the US economy to our chief economic rival. China is outpacing US economic growth by supplying the world with the clean technologies vital today and in the future, including electric vehicles and critical minerals, while the Trump Administration tries to revive a dying coal industry.

Also, onshore wind in the US is hitting a cliff, even in the most wind-powered state, Iowa, which generates about 2/3 of its electricity from wind. A combination of local...

And, Melissa Williams a storyteller for the Center for Climate and Environmental Justice Media or CEJM shares her community’s efforts and concerns a...

As geothermal heating and cooling slowly spreads in the U.S., some communities and utilities are looking to grow small pilot projects into much larger networks of pipes and heat pumps that extract and store heat in the earth to warm and cool homes and businesses as needed. We hear about a large geothermal HVAC system that demonstrates the possibilities and benefits of scaling up.

Also, classic science fiction tends to assume that if aliens visit Earth, they will have done so thanks to using math and science that’s like our own. But physicist Daniel Whiteson an...

The Trump Administration is withdrawing the US from the scientific Intergovernmental Panel on Climate Change or IPCC, which reports agreement about the basic scientific facts of global warming and the impact of core technologies to address it. A lead author of the IPCC fourth assessment report in 2007 explains how the fossil fuel industry has long pushed for such an action. 

Also, the burning of fossil fuels is linked to some 300,000 deaths in America every year, not to mention the related carbon emissions that promote global warming. We discuss the major health and economic costs linked to pollution. 

The Trump Administration recently announced plans to withdraw the United States from dozens of United Nations treaties and organizations including the UN Framework Convention on Climate Change, a treaty that was ratified by the US Senate in 1992 and is the key international forum for addressing the climate crisis. Marianne Lavelle, the Washington Bureau Chief for Inside Climate News, speaks about what this decision could mean for global climate progress.

Also, the Colorado River provides water to seven western states, and there is not enough to go around. Recently the federal government ordered the states to agree on...

In its first year, the second Trump Administration slashed environmental regulations and programs, overstepping its executive authority in the eyes of some environmental advocates. But the judicial and legislative branches appear unable or unwilling to provide a check on what legal expert Pat Parenteau sees is abusive executive power threatening the health of people and planet.

Also, the American prairie is one of the most biodiverse ecosystems in the world, but today just one percent of eastern tallgrass prairie remains, and western shortgrass prairie is disappearing at a rate of more than a million acres a year...
