COP28 Climate Summit: Pledges & Realities

Climate Change & COP28 (start time: 1:30) A major global climate conference is taking place now in Dubai, amidst a year of record-breaking heat, wildfires, floods and more around the world.  COP28 is short for the 28th Conference of the Parties of the United Nations Framework Convention on Climate Change. The aim of the conference is to have nations address climate change by pledging to cut greenhouse gas emissions (and actually following through), investing more in clean energy, and having richer nations help fund climate-adaptation measures in developing countries and especially vulnerable communities. Our guests today are Dr. Alice Alpert, a senior scientist at Environmental Defense Fund who previously served on the U.S. delegation to some COP conferences; and science journalist Tom Yulsman, who directs the Center for Environmental Journalism at CU Boulder.

Toward Sustainable Agriculture

Sustainable Agriculture (starts 3:06): We couldn’t feed the planet without nitrogen, a vital nutrient for crops. But most soils don’t produce enough of it to feed anywhere near our 7 billion-plus humans on the planet. So, for nearly a century we’ve been applying synthetic fertilizer—mainly nitrogen and phosphorus — to grow crops for animals and people. But we have overindulged, creating vast amounts of waste, in the form of nitrogen pollution of waterways and the atmosphere. State and federal regulations have pressured growers to dramatically reduce fertilizer runoff from their fields. But it’s not been enough. Another approach – call it the carrot versus the stick – is also taking hold. Major food retailers, wholesalers, and producers, such as Walmart, United Suppliers and Unilever are transforming their whole supply chains, making food production less carbon- and nitrogen-intensive. Suzy Friedman, a sustainable agriculture expert with the Environmental Defense Fund, discusses with host Susan Moran how programs such as SUSTAIN help large food companies shrink their environmental footprint.

Habitat Exchanges // More Frequent Wildfires

Habitat Exchanges (starts at 3:00):  The greater sage grouse is ruffling feathers all the way to Washington.  September 30th is the deadline for the US Fish & Wildlife Service to determine whether to list the grouse under the Endangered Species Act. More than a third of the sage grouse’s shrinking range is on private land. Which is why many ranchers, oil and gas developers and other landowners have been scrambling to keep the grouse from getting listed. Listing would mean tighter restrictions on land use. The Environmental Defense Fund (EDF) is one of several environmental organizations that are trying to help come up with ways to preserve the sage grouse and its habitat without cramping the livelihood of ranchers and other land owners. One of the newest voluntary tools is what is called a habitat exchange, a marketplace with buyers and sellers of conservation credits.  How On Earth’s Susan Moran talks with Eric Holst, associate vice president of EDF’s working lands program, about these exchanges.

More Frequent Wildfires (starts at 15:30):  This summer, fires have raged across much of the Northwestern U.S. The towering blazes, many of which are nowhere near being contained, have already charred more than two million acres of land. It’s a story that’s becoming increasingly common. Big fires like these are erupting more often than they did just decades ago, scientists say, and many place the blame on climate change.  On today’s show, Brian Harvey, a forest ecologist at the University of Colorado Boulder who studies the causes and consequences of extreme fires, talks with us about why wildfires have grown more frequent in recent years — and what that means for the recovery of the nation’s forests.
