I think it’s good politics to speak loudly and clearly about the climate crisis. Time to end the climate hushing billmckibben.substack.com/p/lets-talk-...

Happy #EarthDay ! 🎉 A moment to remember we are one planet, one family. Show our Earth Love today and everyday. Lead with unity and love. Not Hate and division. Each day is a new opportunity to learn and grow. Stewards of this planet. This pale blue dot. None of us can do this alone.

Happy Earth Day 💚💙

Happy Earth Day! 🌎🌳🚇🚌🚲🚶‍♀️🌆 What better way to celebrate than to take transit, ride a bike / mobility device, or go on a stroll Not sure about your local transit options? For MoCo folks, these can help! rideon.app/directions www.wmata.com/schedules/tr... Or my personal fave: transitapp.com

business opportunity, rural, urban, we need these factories everywhere to replace the fossil, linear, synthetic construction materials. Biobased, agricultural byproducts are the PV panels, wind power and the bicycle of the construction transition. www.alibaba.com/trade/search...

The Strait of Hormuz + surrounding seas are critical ecologically as well as politically. Coral reefs, whale sharks, dolphins, endangered Arabian humpback whales, seagrass meadows supporting dugons, islands harbouring green turtles - just some of the creatures + ecosystems in + near the Strait. 2

"Our doubts are traitors and make us lose the good we oft might win by fearing to attempt" -William Shakespeare, Measure for Measure #WetTribe #TidetotheOcean #ShakespeareSunday #HopeBudget #ActionBias

We can build fast electric rail between nearby city centers. We can insulate and seal our buildings. We can eat how doctors recommend for our health and longevity; that, plus reducing food waste, can cut the (fossil-fueled) fertilizer/energy/pollution intensity of agriculture by ~half.

The solutions aren't just buying electric widgets. We can also shift from car-dependent sprawl to attached housing in dense multi-use neighborhoods with frequent public transit and protected active transit. This can reduce energy demand by >half while improving convenience and public health.

Remember, not density OR trees. Density AND trees. Better cities are climate action. #UrbanTruth

Can you hear forest recovery? In Costa Rica, scientists analyzed 16,000 hours of audio to measure the success of payments for ecosystem services. The data shows that naturally regenerated forests now sound more like protected primary forests than pastures, signaling a true return of biodiversity.

Eventually we will come to realize that carbon-free electricity needs to be built and maintained as a public good. Markets have been far too slow to decarbonize grids. Major structural barriers remain and may even get worse just when we need to accelerate faster.

After 100 years of copper mining, parts of Tasmania’s King River are "biologically dead." As the demand for minerals for EVs and AI surges, these rivers serve as a stark warning: the cost of mining lasts centuries. @slovgren.bsky.social reports for #Mongabay.

Biodiversity of #rainforest can recover within decades when located in highly connected landscapes because animal mobility drives natural recovery. Our @reassemblynet.bsky.social synthesis paper is out @nature.com: tinyurl.com/4w24a96b @sgn.one @unimarburg.bsky.social @jocotoco.bsky.social 🌐🌎🧪

Our planet is called Earth. Until recently, most people lived in buildings made of earth, whether farmers or nobles, and many still do. Building with earth does not cause man-made climate change. Earthlings, let's build with earth again and forget the short period in which we forgot this.

Your kindness echoes in the hearts you’ve touched… #BloomOnPurpose #photography #nature #ArtInNature

France passed a law requiring solar panels on every parking lot with more than 80 spaces. Equals 10 nuclear reactors Reduces heat island, shades cars The US -- 800 million parking spaces. Most of them are uncovered asphalt sitting in direct sunlight. Why aren't we doing this?

Bad news - we'll soon blow through the carbon budget for stabilizing global temperature at 1.5C Good news - progress on clean energy suggests it is possible to stabilize by 2C www.nature.com/articles/s41... What does the science say? Neither is a magic threshold. Every bit of warming matters.

Today in convo w/ contractor: we're creating a living laboratory using & testing alt materials & methods. Wood block floor, crushed/ reclaimed brick floor, vintage glass for glazing, biochar, hempcrete, pallet board lath, ♻️ glass + slag concrete. These + more 🟩 bldg will mean beautiful space & data

depaving streets and parking spaces for micro forests and urban heat island mitigation ftw

Excellent work here from @kencaldeira.com and team! One nice feature of high temperature heat is that it's easy and relatively cheap to store compared to electricity.

Caring about this planet is its own kind of resilience. A stubborn, beautiful refusal to give up on the future. This #EarthMonth, we're making space for real stories and the question that drives everything: #whyclimate? Share yours in the comments. #EarthMonth #WhyClimate #ClimateAction

Here’s one that’s really important to understand and remember, especially if you work in a city hall — the best transportation plan is a great land-use plan. #UrbanTruth

Density

Why do so many Americans die while walking? To find out, I spoke with University of New Mexico’s Nick Ferenchak, who leads the only US research center focused specifically on pedestrians and cyclists. TL;DR: Fast urban roads are a huge factor, and car bloat amplifies risk.

Heat batteries delivering up to 1,200C using off peak electricity: A Scottish whisky distillery just claimed a world first — producing high-temperature steam for distilling using stored green electricity instead of fossil fuels. www.bbc.co.uk/news/article...

One thing I really want NYC to get to in its bike lane designs is the idea of social cycling. A parent should be able to ride next to a child. Two friends should be able to ride next to each other. A senior on an adult trike should not have to worry about blocking faster cyclists. Etc.

Around *1/5* of all the species that live in a natural forest need dead wood. So no, it's not 'wasted' or 'untidy'. Even in your garden, spare a thought and leave it for them.

Bats need forests and forests need bats! 🌲 Many of Canada’s bat species depend on tall, old trees with cavities and crevices that take decades to form. In turn, bats support the health of these vital ecosystems. As those trees disappear, so does critical bat habitat.

Most food consumed in the US is already produced here. We were a net ag exporter for 60 years & only since 2019 net importer, bc we like access to tropical products & off-season produce. Also, we waste ~40% of the food we produce, and use the majority of our corn & soy for animal feed and biofuels.

Imagine just waking up every day to new human achievements, adventures, discoveries and successes, instead of wars, and famine and desecration of our own making.

This is an astonishing fact, yet it is often overlooked when discussing sustainable agriculture and regenerative farming. The biggest thing we can do to fix the food system -- feeding more people, with less harm to the planet -- is to shift to more sustainable diets and phase out biofuels.

8) Change and innovation is not driven by half empty thinking. It needs optimism combined with pragmatism.

Life on a sustainable construction site fr. From code to the vendors & contractors, it becomes hard to positively stay the course. Every day is an invitation to quit. A nihilistic call asks "why do you keep fighting to change when no one cares? It doesn't matter". The reality: every 🟩 shift matters

Austin TX: Please foster a dog from Austin Animal Services! They have 31 dogs living in crates in a hallway right now! Even a few days break can be beneficial and help dogs get adopted.

Industrial heat pumps are one of the most underrated technologies in the energy transition. They work. They scale. And they’re finally moving from demonstration to deployment. Here’s a 95-tonne heat pump component just traveled hundreds of kilometres by river to reach BASF’s Ludwigshafen site.

Interior excavation in a narrow historic structure w/ little clearance requires a certain kind of temperament. Watching the excavator work from one side to the other in these confines is like a fieldwork meditation

While restored rivers from flash flooding to wetlands from draining almost never achieves their original function we degraded, restoring wetlands has myriad benefits for people, wildlife & climate mitigation efforts

This everyday as a #sustainble #resilience project. People are like: we could've gotten you concrete for 2k/truck, dyk how little lumber costs, you've wasted time managing this, or you didn't save emissions b/c you shipped salvage. There's always cost to trying to do better. Only the real ones know

Bumblebees don’t understand glass - they get confused and trapped and exhausted. And they die. Likewise with polytunnel plastic. So if you see or hear a #bumblebee buzzing and banging against a window in your house SHE NEEDS YOUR HELP - AND QUICKLY! She’s in trouble. Big trouble! 2/11 #bees

Good new on the #decarbonize front: "heat pump market shift is durable... Heat pumps outsold gas furnaces for the fourth year in a row in 2025, & outsold air conditioners for the first time ever in September 2025" MD, DC, NY, MA, MN & CA continuing policy shifts to decarbonize

Today is International Beaver Day! Celebrate nature’s environmental engineers. Beavers transform degraded, narrow streams into vibrant, complex wetlands by building dams that slow water, increase biodiversity, and raise water tables. #WetTribe #TidetotheOcean

This planet did not ask for us. It was spinning, breathing, and pulling the tide in and out long before we showed up with our noise and our cities and our grief. Empires crumble, Mountains return to the sea. It’s important we all leave the world better than found it. 💙

Like Kyle says, the entry cost for cities to implement bike lanes, street trees & the best of Paris' quality of life improvements is cheap & straightforward while the benefits are massive. Being cheap & easy means they could also be quick to implement w/ the right support from mayors & city councils

Did you know that ponds are a mechanism to address bird, plant & animal conservation? There are many benefits to ponds, including for migratory birds as stop over sites on their journeys which can last hundreds or thousands of miles
