NOAA – How On Earth

Climate Science, Human Lives at Risk

Standing Up for Science (start time: 6:39) Since President Trump began his second term in January, his administration has been on a rapid-fire campaign to slash federal funding for scientific research, particularly in the fields of climate and earth systems science. Colorado is feeling the pain. President Trump’s budget proposal for fiscal year 2026 includes steep cuts in funding to NOAA, or the National Oceanic and Atmospheric Administration, which funds and manages research on wildfires, extreme heat waves, floods, and much more. NOAA contributes a huge amount to Colorado’s economy, and its research helps saves lives. The proposed budget cuts would likely result in the shuttering of two cooperative institutes in Colorado that are affiliated with and largely funded by NOAA. Those are the Cooperative Institute for Research on Environmental Sciences (CIRES) at CU Boulder, and the Cooperative Institute for Research in the Atmosphere (CIRA) at Colorado State University. In today’s show, host Susan Moran talks with Dr. Waleed Abdalati, director of CIRES and a professor of geography at the University of Colorado Boulder.

Tackling Climate Change and Science Cutbacks (start time: 7:03) In this week’s show we discuss the ongoing barrage of executive orders by the Trump administration; and the impacts of defunding of federal agencies, scientific research and scientists focusing on climate change and the environment. We also explore how the legal and political landscape, including pushback against the administration’s actions, are shifting. How On Earth host Susan Moran interviews Marc Alessi, a climate scientist at the nonprofit organization Union of Concerned Scientists (UCS); and Delta Merner, a geographer and associate director of the Climate Accountability Campaign at UCS. Dr. Alessi was an organizer of a 5-day event in May with climate scientists and meteorologists in May, called 100 Hours to Save America’s Forecasts. And Dr. Merner is an organizer of a public virtual event on Wednesday, July 16, called “Meeting the Moment Through Climate Litigation” (2:00-3:00 p.m. MDT).
Also on this week’s science calendar, check out this FDA expert panel on menopause and hormone treatment, available livestreamed on the FDA’s YouTube channel. It’ll be held on Thursday, July 17, 11:00 a.m. to 1:00 pm. MDT.

Deep-sea Coral Reefs // Mineral-Mining

This week’s How On Earth offers two features:

Deep-sea coral reef discovery (start time: 0:58) Scientists recently discovered and mapped the largest known deep-sea coral reef in the world. It’s located up to 200 miles off the U.S. Atlantic Coast, and it’s larger than Vermont. The news comes as a bright spot for oceans and marine life, when ocean acidification related to global warming, as well as overfishing, have been destroying coral reefs around the world. Contributing host Kara Fox interviews Kasey Cantwell, the operations chief for the Expeditions and Exploration Division of the National Oceanic and Atmospheric Administration, about the big discovery and its implications.

Deep-sea mining: promises and perils (start time: 10:48) Exploratory mining of the ocean floor for minerals began decades ago. Although commercialization remains elusive, some some companies are moving rapidly to exploit the seabed for commercial use. They aim to harness critical minerals – manganese, nickel, copper, cobalt and others – for use in the production of electric vehicle batteries, cell phones, wind turbines, etc. Some scientists, environmentalists, a regulatory body, and even some auto and tech companies, have called for at least a temporary ban on seabed mining, out of concern about its impact on marine life. Host Kara Fox interviews Farah Obaidullah, founder of the conservation group The Ocean and Us, and editor of a book of the same name, about seabed mining.

Today’s show offers two features:
Oil & Gas Impacts (start time: 1:05) Proposition 112, which would require oil and gas wells to be at least 2,500 feet from homes, schools, parks and other buildings, has highlighted mounting public concerns about the health, social and other impacts of extensive drilling along Colorado’s Front Range. Weld County is center stage for the latest oil and gas boom; nearly half of Colorado’s 55,000 active wells are located there. Jason Plautz, a Denver-based journalist, discussed with host Susan Moran the science and politics surrounding drilling activities, and whether explosions such as the one in Windsor last December could happen in many other locations. Plautz and Daniel Glick wrote a feature article that has just been published in High Country News.

Healthy Planet+Healthy Humans? (start time: 14:46) Matthew Burgess has been immersed in thinking about and studying how we humans, and the planet we inhabit, can both remain intact—in fact, can both thrive–well into the future. What’s he smok’in, you might ask? In fact, he is a serious environmental scientist at the University of Colorado Boulder. Dr. Burgess and nearly two dozen colleagues authored a recently published scientific paper that applies models to show how we can meet demands of increased populations and economic growth in 2050, while simultaneously achieving bold and effective conservation and climate goals set forth by the United Nations. Dr. Burgess is an assistant professor in Environmental Studies, with an additional appointment in Economics. And he works at the Cooperative Institute for Research in Environmental Science (CIRES), the collaboration between the National Oceanic and Atmospheric Administration (NOAA) and the University of Colorado. He discusses the paper and its implications with hosts Susan Moran and Joel Parker.

Geoengineering the Climate

Hacking the Planet (start time: 10:24):
It’s tough to wrap one’s mind around just how monumental and consequential the problem of climate change is. So dire that scientist and engineers for years have been exploring ways to “hack” the planet–to manipulate the global climate system enough to significantly reduce planet-warming gases or increase the Earth’s ability to reflect solar radiation. This audacious scheme, called geoengineering, only exists because many scientists think that human behavioral change, industry regulations, international treaties and national legislation, have not done enough — can not do enough – to keep us from careening toward climate catastrophe.
Our guests today have given this huge challenge a lot of thought and some research. Dr. Lisa Dilling is an associate professor of Environmental Studies at CU Boulder and a fellow at the Cooperative Institute for Research in Environmental Sciences, or CIRES. Dr. David Fahey is a physicist at the National Oceanic and Atmospheric Administration, or NOAA. He directs the Chemical Sciences Division at NOAA’s Earth System Research Lab in Boulder.

Some relevant materials on geoengineering:
2017 study on public perception of climate change;
2015 National Research Council committee evaluation of proposed climate-intervention tchniques.

Methane Emissions From Natural Gas

Methane Madness (start time: 2:20) More than a decade ago, scientists noted that the area where Colorado, New Mexico, Arizona and Utah meet, known as Four Corners, appeared to be emitting a curiously large amount of methane. In a new study, a team of scientists have traced the source: more than 250 gas wells, storage tanks, pipelines and processing plants associated with oil and gas development in the San Juan Basin. The basin is one of many places where new drilling technologies, including horizontal drilling and hydraulic fracturing, have propelled a boom in natural gas extraction. The boom has transformed the U.S. energy mix. Our two guests discuss with hosts Daniel Glick and Susan Moran the science and public health aspects of this study as well as the human side of living near natural gas wells in Colorado. Dr. Colm Sweeney co-authored the recent Four Corners study. He is the lead scientist for NOAA’s Earth System Research Lab Aircraft Program, and he is a research scientist with the Cooperative Institute for Research in Environmental Sciences, or CIRES, at the University of Colorado Boulder. Our other guest, Dr. Christopher Clack, is a physicist and mathematician with CIRES whose research focuses on renewable electricity. He shares his personal experience with and documentation of natural gas extraction.

Electric Car Road Trips // Renewable Energy Nation . . . in 15 Years

Tesla Superchargers - Rural Arizona — Tesla Superchargers – Rural Arizona

Electric Car Road Trips (starts 3:42): We go on a road trip with How on Earth’s Shelley Schlender to see how all-electric vehicles are exceeding “range anxiety” by driving coast to coast, all on electricity. Along the way we talk with Boulder Nissan’s Nigel Zeid about regional plans to help more drivers “plug in” and with Hunter Lovins, head of Natural Capitalism Solutions.

Renewable Energy Nation (starts 11:53): Joel Parker talks live with NOAA scientist Alexander MacDonald and Christopher Clack, a mathematician at the University of Colorado-Boulder. They have developed a model that demonstrates how the entire U.S. can run on solar and wind power–with existing technologies, with no batteries, and at lower cost than today’s prices–within 15 years. For more information, see this video and these animations of:
