Reflections from Judy, March 2021
There’s some very encouraging climate change action these days. More and more, I’m seeing an integrated approach to how climate change can, and needs to be, addressed.
The same goes for the urgency.
The 30 x 30 initiative is (not surprisingly) strongly supported by land trusts and conservation organizations. Protecting land is what they/we do. The timing is important as there is increasing evidence that many of the lands and waters we are collectively working to conserve are near, or already at, a tipping point.
This will mean different land management practices that prioritize slowing down climate change as well as bolstering climate resilience. It will also mean conservation-oriented folks supporting community resilience and engagement, reducing the need for energy (energy conservation), and identifying how renewable energy is compatible with land and water. It’s not one or the other; it’s going to take an integrated approach that will entail conservation organizations stretching their perspectives to help pick up the pace and expand their partnerships.
Yet that won’t happen without you. Conservation organizations need to feel supported as they venture into new partnerships, try out new ideas, and tackle new approaches for both slowing down climate change and adapting to changing circumstances. Let them (or organizations you belong to) know you care and that you support an integrated approach. Help to lead.
When you share the challenges and solutions around climate change in a manner that connects with people’s shared values and with their communities you too are part of that change. That’s part of why I include the variety of articles below. Feel free to share them with people and organizations you know. Help them connect the dots. Frame the ideas as part of a solution-based approach.
As people who care, we need to continue to face the reality of climate change—and encourage solutions that will authentically reduce the use of fossil fuels and build healthy, and vibrant, communities.

70 bipartisan mayors commit to conserving 30% of U.S. lands by 2030
“Seventy of the nation’s mayors have endorsed a campaign dedicated to conserving 30% of America’s lands, waters and oceans by 2030, an effort dubbed the 30×30 initiative.
The mayors represent 29 states, and Washington, D.C. Most serve in a nonpartisan or independent office, while 21 are Democrats and four are Republican. Cities represented include Chicago, Miami-Dade County and Phoenix…”
Many overheated forests may soon release more carbon than they absorb
New research shows that Earth’s overheated climate will alter forests at a global scale even more fundamentally, by flipping a critical greenhouse gas switch in the next few decades. The study suggests that, by 2040, forests will take up only half as much carbon dioxide from the atmosphere as they do now, if global temperatures keep rising at the present pace.
The study, published Wednesday in Science Advances, analyzed more than 20 years of data from about 250 sites that measure the transfer of carbon dioxide between land and plants and the atmosphere—the way the planet breathes. Forests and the rest of Earth’s land-based ecosystems take up about 30 percent of human carbon emissions, so any big change in that process is important…
Climate justice: the intersection of climate science, environmental and social justice
The Earth System Science Center has announced the lineup for its spring 2021 Climate Dynamics seminar series. The series will focus on the cutting-edge climate research being conducted in the Earth and Environmental Systems Institute and the Climate Science dual-title graduate program in the College of Earth and Mineral Sciences at Penn State. The seminars, which are free and open to the public, take place from 11:15 a.m. to 12:30 p.m. on Wednesdays via Zoom.
You may appreciate listening to the webinar about climate change, environmental and social justice.
Report: Exposure to climate change drives stability or collapse of desert mammal and bird communities
“Understanding how our warming climate affects vulnerable species is of paramount importance. However, predicting responses is complicated because species are complex and may adapt or respond in distinct ways…”
How desert birds can survive with very little water
In the desert Southwest, summer temperatures sizzle, rising well over 100 degrees. And in some parts of the desert, there is not a drop of water for miles.
Yet some birds thrive in this scorching landscape. Here a Black-throated Sparrow sings from a thorn scrub. Now, a Cactus Wren announces itself atop a barrel cactus. And neither will be flying miles every day to the nearest source of water. So how do they survive?
How climate change pushes even the hardiest desert birds past their limit
The Mojave Desert, like many deserts across the world, is getting hotter and drier. Over the last century, it’s warmed by about 3.6 degrees Fahrenheit (2 degrees Celsius), and its already sparse rainfall has declined by 20 percent in some areas. Even before modern climate change, the Mojave’s birds lived at extremes; many desert birds have evolved special drought adaptations to save water. Now they’re facing conditions that exceed their physiological limits, according to new research published in Science.
Benefits of agrivoltaics across food, water, energy sectors
Food and energy security need not be competing objectives. In fact, taking a holistic, integrated approach to food-energy-water decision making can increase resiliency of both food and energy systems…
Farms will harvest food and the sun, as Massachusetts pioneers ‘Dual-Use’ Solar
Fickle weather and fluctuating prices make farming a risky business, so five years ago, [Paul] Knowlton installed a new cash crop: solar energy. He turned 19 acres into two solar energy fields. “Doing the solar was very beneficial,” he says. “In the wintertime there is no revenue for a farm. It’s a tough game.”
Knowlton wants to increase the production of solar power on his farm, expanding it to another 14 acres. But this time, cutting-edge technology is making it possible to harvest both the sun’s energy and crops on the same land. It’s called “agrivoltaics” or “dual-use solar”…Knowlton has nine children, and hopes solar will help the farm stay in the family. “We’re going to keep it for the next generation to enjoy,” he says.
Juneau’s climate change solutionists: preserving wetlands and peatlands with Koren Bosworth
While the rest of the world celebrated World Wetlands Day on February 2nd, we in Juneau might wonder if every day is wetlands day, especially when venturing off a developed trail.
We are lucky for it. Our spongy ground might be inhospitable to tromping and building, but it performs a service arguably more important than recreation or development: carbon sequestration.
Juneau’s peatlands and wetlands are carbon sinks, complex biomes that trap carbon in an anaerobic environment, slowing the decomposition of organic material. Coastal wetlands can store five times as much carbon as a tropical forest over time; peatlands store ten times more carbon than other kinds of ecosystems…
