1. Caribbean reef sharks rebound in Belize with shark fishers’ help

“Caribbean reef shark populations have rebounded beyond previous levels, more than tripling at both Turneffe and Lighthouse atolls[…. The recovery] arose from a remarkable synergy among shark fishers, marine scientists and management authorities[….]”

2. Landmark Ruling on Uncontacted Indigenous Peoples’ Rights Strikes at Oil Industry

“[T]he Ecuadorian government [must] ensure any future expansion or renewal of oil operations does not impact Indigenous peoples living in voluntary isolation. [… E]ffective measures must be adopted to prevent serious or irreversible damage, which in this case would be the contact of these isolated populations,” said the opinion[….]”

3. America's clean-energy industry is growing despite Trump's attacks. At least for now

“The buildout of big solar and battery plants is expected to hit an all-time high in 2025, accounting for 81% of new power generation[….] The industry overall has boomed thanks to falling technology costs, federal tax incentives and state renewable-energy mandates.”

4. Study says endangered Asian elephant population in Cambodia is more robust than previously thought

“A genetic study of Asian elephants […] reveals a larger and more robust population than previously thought, raising hopes the endangered species could slowly recover. […] “With sufficient suitable habitat remaining in the region, the population has the potential to grow if properly protected,” the report concludes.”

5. Scientists are engineering a sense of touch for people who are paralyzed

“[Engineers are] testing a system that can restore both movement and sensation in a paralyzed hand. [… A]fter more than a year of therapy and spinal stimulation, [… h]is increased strength and mobility allow him to do things like pet his dog. And when he does, he says, "I can feel a little bit of the fur."“

6. Florida is now a solar superpower. Here’s how it happened.

“In a first, Florida vaulted past California last year in terms of new utility-scale solar capacity plugged into its grid. It built 3 gigawatts of large-scale solar in 2024, making it second only to Texas. And in the residential solar sector, Florida continued its longtime leadership streak.”

7. Rare frog rediscovered after 130 years

“The researchers discovered two populations of the frog[….] "The rediscovery of A. vittatus allowed us to obtain, more than a century after its description, the first biological and ecological data on the species.” [… S]hedding light on where and how they live is the first step in protecting them.”

8. Community composting programs show promise in reducing household food waste

“The program [increased awareness and reduced household waste, and] also addressed common barriers to home composting, including pest concerns and technical challenges that had previously discouraged participants from composting independently.”

9. Pioneering Australian company marks new milestone on “mission” to upcycle end-of-life solar panels

“[…] SolarCrete – a pre-mixed concrete made using glass recovered from used solar panels – will form part of the feasibility study[….] A second stage would then focus on the extraction of high value materials[…] for re-use in PV and battery grade silicon, [… and] electrical appliances[….]”

10. Beavers Just Saved The Czech Government Big Bucks

“The aim was to build a dam to prevent sediment and acidic water from two nearby ponds from spilling over, but the project was delayed for years due to negotiations over land use[….] Not only did the industrious rodents complete the work faster than the humans had intended, they also doubled the size of the wetland area that was initially planned.”

"To mitigate the negative impacts of climate change, the world needs to quickly transition from fossil fuels to low-carbon energy sources such as solar power.

The chart shows how much this transition has accelerated in the last two decades.

In 2004, it took the world about a year to add one gigawatt of solar power capacity. By 2023, the same amount was added, on average, every single day.

For reference, a gigawatt of solar is enough to power approximately 200,000 homes in the US.

Much of this growth has been driven by China, which by 2023 accounted for about 43% of the cumulative installed capacity worldwide.

A big reason for this acceleration has been a large decrease in the price of solar panels. Since 2001, the price has dropped by about 95%, from $6.21 to $0.31 per watt.

Learn more about why renewables like solar became so cheap so fast."

A collection of hydroponics and solar powered machines I did over the years🌻

There is something about machines that work together with nature, instead against it, that keeps facinating me. I hope to explore this more in the future!

Mobility Outfitters Gearbox Concept, 1998. Described by its designer as "a space vehicle for Earth exploration," the Gearbox was presented at the North American International Auto Show. Features included Solar panels to charge batteries that powered ancillaries when the vehicle was stationary. They also allowed stand-up head room in the cabin when deployed. It was equipped for all-terrain camping with storage compartments below the rear tray. It didn't progress beyond prototype stage and is now part of the collection at the Petersen Automotive Museum

In 1979, Jimmy Carter had solar panels installed at the White House.

Ronald Reagan had them removed.

1. Solar farms managed for nature boost bird abundance and diversity, new study finds

“There were more than twice as many farmland birds in the well-managed solar farms compared with the intensively farmed land, and nearly 16 times as many woodland birds. […] Overall, diversity was 2.5 times higher, while woodland birds were nine times more diverse.”

2. Washington judge blocks Trump’s gender-affirming care ban, says it's unconstitutional in multiple ways

“This marks the second time in a week that a judge has stood in the way of Trump’s attacks on trans kids. [… The ruling grants] a temporary restraining order that halts enforcement of provisions in Trump’s directive that would cut off federal funding to medical institutions that provide gender-affirming care to minors.”

3. Fog harvesting could provide water for arid cities

“17,000 sq m of mesh could produce enough water to meet the weekly water demand of [… the] urban slums. 110 sq m could meet the annual demand for the irrigation of the city's green spaces. Fog water could be used for soil-free (hydroponic) agriculture, with yields of 33 to 44lb (15 to 20kg) of green vegetables in a month.”

4. Audubon Applauds Bipartisan Federal Effort to Protect Delaware River Basin with Critical Reauthorization Bill

“The bill would […] ensure long-term conservation and restoration efforts, expand the official definition of the basin to include Maryland, and prioritize projects that serve small, rural, and disadvantaged communities. […] The watershed provides important year-round habitats and critical migratory stopovers for approximately 400 bird species[….]”

5. mRNA vaccines show promise in pancreatic cancer in early trial

“Half of the people in the study — eight of the participants — responded to the vaccine, producing T cells that targeted their tumors. […] Just two of the patients who had a response to the vaccine had their cancer return during the three-year follow- up, compared to seven of the eight who did not respond to the vaccine treatments.”

6. Minn. Lt. Gov. Flanagan Makes It Official; She's running for U.S. Senate

“[Flanagan has] “championed kitchen-table issues like raising the minimum wage, paid family and medical leave, and free school meals.” If elected, Flanagan, a tribal citizen of the White Earth Nation, would become the first Native American female U.S. senator in history.”

7. Federal Funding Restored for Low-Income Alabama Utility Assistance After Outcry

“A program meant to help low-income Alabamians pay their utility bills has resumed two weeks after it was canceled due to an executive order from President Donald Trump. […] “We can confirm the funds are reaching those affected by the previous pause[….]””

8. Modeling study suggests Amazon rainforest is more resilient than assumed

“[Previous] studies were either conducted with global climate models that used a simplified representation of convection [or were on a regional scale….] According to the computations, mean annual precipitation in the Amazon does not change significantly even after complete deforestation.“

9. States are moving forward with Buy Clean policies despite Trump reversal

““Buy Clean is a great example of how states and other nonfederal actors can continue to press forward on climate action, regardless of what the federal government does,” said Casey Katims, executive director of the U.S. Climate Alliance, a bipartisan coalition of two dozen governors.”

10. The rewilded golf courses teeming with life

“A wildflower meadow, ponds, scrub habitat, coastline and even an area of peat bog can be found on this little 60-acre (24-hectare) plot, which boasts roe deer, otters, lizards, eels and a huge array of insects and birds.”

I really hope they can work the bugs out of this solution, because if it's done right, it'll really be a win-win situation. Less evaporation of water, and solar power being generated every day? Yes, please. We are smart, resourceful beings, and this is far from the most difficult problem we've had to address.

This is also a great example of how we can go back and fix mistakes of the past. We very, very rarely ever come up with technological solutions that take long-term effects on the environment into consideration, and so the way many things are designed often leads to some sort of damage, whether through manufacture, use, disposal, or all of the above. Retrofitting canals (which have been used in agriculture for thousands of years) will have benefits not only in the ways mentioned above, but also gets people thinking more about the impacts we make.

I'm hoping that this will lead to more new technology being developed in ways that already anticipate and account for negative impacts so that they avoid them in the first place, rather than having to engineer new solution many years down the line.

"It is 70 years since AT&T’s Bell Labs unveiled a new technology for turning sunlight into power. The phone company hoped it could replace the batteries that run equipment in out-of-the-way places. It also realised that powering devices with light alone showed how science could make the future seem wonderful; hence a press event at which sunshine kept a toy Ferris wheel spinning round and round.

Today solar power is long past the toy phase. Panels now occupy an area around half that of Wales, and this year they will provide the world with about 6% of its electricity—which is almost three times as much electrical energy as America consumed back in 1954. Yet this historic growth is only the second-most-remarkable thing about the rise of solar power. The most remarkable is that it is nowhere near over.

To call solar power’s rise exponential is not hyperbole, but a statement of fact. Installed solar capacity doubles roughly every three years, and so grows ten-fold each decade. Such sustained growth is seldom seen in anything that matters. That makes it hard for people to get their heads round what is going on. When it was a tenth of its current size ten years ago, solar power was still seen as marginal even by experts who knew how fast it had grown. The next ten-fold increase will be equivalent to multiplying the world’s entire fleet of nuclear reactors by eight in less than the time it typically takes to build just a single one of them.

Solar cells will in all likelihood be the single biggest source of electrical power on the planet by the mid 2030s. By the 2040s they may be the largest source not just of electricity but of all energy. On current trends, the all-in cost of the electricity they produce promises to be less than half as expensive as the cheapest available today. This will not stop climate change, but could slow it a lot faster. Much of the world—including Africa, where 600m people still cannot light their homes—will begin to feel energy-rich. That feeling will be a new and transformational one for humankind.

To grasp that this is not some environmentalist fever dream, consider solar economics. As the cumulative production of a manufactured good increases, costs go down. As costs go down, demand goes up. As demand goes up, production increases—and costs go down further. This cannot go on for ever; production, demand or both always become constrained. In earlier energy transitions—from wood to coal, coal to oil or oil to gas—the efficiency of extraction grew, but it was eventually offset by the cost of finding ever more fuel.

As our essay this week explains, solar power faces no such constraint. The resources needed to produce solar cells and plant them on solar farms are silicon-rich sand, sunny places and human ingenuity, all three of which are abundant. Making cells also takes energy, but solar power is fast making that abundant, too. As for demand, it is both huge and elastic—if you make electricity cheaper, people will find uses for it. The result is that, in contrast to earlier energy sources, solar power has routinely become cheaper and will continue to do so.

Other constraints do exist. Given people’s proclivity for living outside daylight hours, solar power needs to be complemented with storage and supplemented by other technologies. Heavy industry and aviation and freight have been hard to electrify. Fortunately, these problems may be solved as batteries and fuels created by electrolysis gradually become cheaper...

The aim should be for the virtuous circle of solar-power production to turn as fast as possible. That is because it offers the prize of cheaper energy. The benefits start with a boost to productivity. Anything that people use energy for today will cost less—and that includes pretty much everything. Then come the things cheap energy will make possible. People who could never afford to will start lighting their houses or driving a car. Cheap energy can purify water, and even desalinate it. It can drive the hungry machinery of artificial intelligence. It can make billions of homes and offices more bearable in summers that will, for decades to come, be getting hotter.

But it is the things that nobody has yet thought of that will be most consequential. In its radical abundance, cheaper energy will free the imagination, setting tiny Ferris wheels of the mind spinning with excitement and new possibilities.

This week marks the summer solstice in the northern hemisphere. The Sun rising to its highest point in the sky will in decades to come shine down on a world where nobody need go without the blessings of electricity and where the access to energy invigorates all those it touches."
