Energy and Wildlife Conservation: A Two-Pronged Approach

by Alix Underwood

At the 2024 conference of The Wildlife Society (TWS)  in Baltimore, I was struck by the prevalence of one topic: low-carbon energy development. There were eight sessions with “renewable energy,” “solar,” or “wind” in their titles, and issues related to these energy sources permeated many other sessions. At a policy priorities meeting, low-carbon energy dominated the discussion, with professionals and academics from across the country sharing their unique concerns.


Winds of Change in Lincoln County

by Dave Rollo

Rolling hills and wide-open plains typify eastern Oklahoma. Gulf Coast and Canadian air masses converge over these plains, creating a near-constant pressure gradient called the low-level jet (LLJ). The result is perpetual air currents in the central U.S. “wind corridor,” which make the region ideal for wind energy projects.

The United States’ top five wind-energy producers—Texas, Iowa, Oklahoma, Kansas, and Illinois—form a southwest to northeast diagonal through the center of the country.


Will DC Break Free of Its Methane-Gas—and Economic-Growth—Shackles?

by Alix Underwood

How do we stop climate change? One decommissioned fossil-fuel pipe at a time, via hard-fought local battles to change energy infrastructure and decrease energy consumption. Who do we fight these battles against? Profit-hungry corporations that monopolize energy markets and back-pocket politicians that help them guard the fossil façade.

In the U.S. capital, the climate-change rubber hits the road as activists pressure an obscure and unelected decision-making body,


Hitting the Pause Button in Colorado Springs

By Dave Rollo

El Paso County is in the eastern foothills of the Rocky Mountains in a region known as the “Front Range,” the mountains first encountered by settlers traveling westward from the Great Plains. The Front Range includes such wonders as Mount Blue Sky and Pikes Peak. But it also refers to a chain of cities and the urban spatial expansion between them that has propagated within and along the foothills.


A Steady Stater’s Response to the Harris-Trump Debate

by Brian Czech

“Harris wiped the floor with Trump.” At least that’s how today’s Washington Post kicked off a discussion among in-house columnists. But for voters who prioritize Planet Earth for present and future generations, the 2024 presidential election is a classic example of seeking the lesser of two evils. Neither Kamala Harris nor Donald Trump is a student—much less a champion—of sustainability. They probably think “limits to growth” pertains to poll results or crowd size.


Two Degrees: Guardrail? Or Guide Rail to Disaster?

by Kent Peacock

The idea that 2⁰C is a safe guardrail against global heating was a guesstimate by an economist almost fifty years ago, and it had a sketchy scientific basis even at that time. In November 2023, a consortium comprised of many of the top glaciologists and climate scientists in the world published a report entitled “The State of the Cryosphere 2023—Two Degrees is Too High.” (See also the review on Carbon Brief.)  The only hope of preventing catastrophic sea-level rise,


We Asked for Science. We Got Sustain-a-Babble.

Editor’s Note

CASSE encourages members and readers to hold their government agencies to account on the conflict between economic growth and environmental protection. Last week, Brian Czech presented Gag-Ordered No More to the Canadian Association for the Club of Rome, concluding with recommendations for engaging agency directors. We follow up this week with a letter from the Qualicum Institute (British Columbia) to Canada’s Minister of Environment and Climate Change,


Climate Engineering: Doubling Down on Bad Habits

by Gary Gardner

Social psychologists tell us it takes about 66 days to form a new habit. In my experience that’s only half true. Sixty-six days to form a good habit, yes, but about 66 hours to form a bad one. If I reach for a donut at breakfast, then do the same the next two days, I seal the deal and establish a habit of bad eating.


A New Papal Statement Hits—and Misses—the Mark

by Gary Gardner

Religious groups have long been players in movements to create a better world, from the anti-apartheid and civil rights movements to initiatives on arms reduction, debt forgiveness, and divestment from fossil fuels. It makes sense that they are involved in the sustainability movement as well. Sustainability, including the effort to create a steady state economy, requires a shift in one’s worldview and values,


Three Telling Takeaways from Climate Week in New York City

by Daniel Wortel-London

New York City was busier than usual last week.

The occasion was Climate Week, a host of events devoted to charting and increasing environmental progress. Hundreds of sold-out summits, covering everything from biodiversity to energy, could be found across the metropolis. And within those halls, would-be thought leaders discussed the challenges of sustainability with both earnestness and self-congratulation.

There was a tension,
