Living on Earth

Boosted by climate change, this year’s El Niño has intensified into a “Super El Niño,” meaning sea surface temperatures in parts of the Pacific are over 2 degrees Celsius hotter than average. How this has brought one strong storm after another churning across the Pacific Ocean while shutting down most Atlantic storms, and what this super El Niño may bring in the months ahead. Also, Atrazine is the second most widely used weed killer in the U.S. after glyphosate, which you might know from RoundUp. Much like glyphosate, atrazine can disrupt hormones and has been linked to serious health impacts, including cancer. Atrazine is also wreaking havoc on aquatic ecosystems, and a recent report from the Center for Biological Diversity finds nearly a quarter of all river miles in the US contain harmful levels. And in her award-winning novel A Guardian and a Thief, Megha Majumdar places her characters in the near future in a climate-changed Kolkata, India, where she grew up. She discusses how the climate crisis may present the kinds of difficult moral choices her characters grapple with. --- We want to hear from you!

The closely watched race for US Senate in Maine is pitting two environmentally concerned candidates against each other. Not only do Republican Susan Collins and Democrat Troy Jackson both have fairly similar green and climate views, they’re from the same rural county and both have roots in the lumber industry that’s so important to the state. Also, in Ann Arbor, Michigan, public power advocates have battled since 2018 to take electricity non-profit, and hope to win a referendum vote in November. But strong opposition from dividend-paying DTE Energy is being stoked by an alleged misinformation campaign with claims of higher costs of going public from what seems to be at least one citizen group that is in fact funded in part by DTE. And in 2022, President Biden’s signature climate bill appeared doomed in the 50-50 divided Senate when West Virginia Senator Joe Manchin, a centrist Democrat with close ties to the fossil fuel industry, declined to pledge his critical vote. But negotiations restarted in secret, and the largest climate package in US history became law. Leah Stokes’ 2026 book The Carbon Wave: A Story of Democracy, Parenthood, and the Race to Protect Our Planet tells the gripping story of how the Inflation Reduction Act came together and cleared the final hurdles. --- We want to hear from you!

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.
