When rainforests died, the planet caught fire: New clues from Earth’s greatest extinction

When Siberian volcanoes kicked off the Great Dying, the real climate villain turned out to be the rainforests themselves: once they collapsed, Earth’s biggest carbon sponge vanished, CO₂ rocketed, and a five-million-year heatwave followed. Fossils from China and clever climate models now link that botanical wipe-out to runaway warming, hinting that losing today’s tropical forests could lock us in a furnace we can’t easily cool.


I pointed this out decades ago and nobody listened. Now here we are. But hey, someone could roll up this newspaper and beat Brazil with it.

Fighting fire with fire: How prescribed burns reduce wildfire damage and pollution

Wildfires are becoming more intense and dangerous, but a new Stanford-led study offers hope: prescribed burns—intentionally set, controlled fires—can significantly lessen their impact. By analyzing satellite data and smoke emissions, researchers found that areas treated with prescribed burns saw wildfire severity drop by 16% and smoke pollution fall by 14%. Even more striking, the smoke from prescribed burns was just a fraction of what wildfires would have produced in the same areas.


And how long did it take white people to figure out what tribal folks have been doing for, oh, 20,000+ years?

Beavers restore lands damaged by wildfire, human abuses, or other causes. 

This is especially useful with climate change causing more drought.  I recommend recruiting all available keystone species to resist the decline.  Good examples for Turtle Island / North America include beavers, buffalo, goldenrod, milkweed, oak trees, prairie dogs, redwood trees, salmon, sea otters, and wolves.  While not everyone has the resources to house any of those personally, you can still support organizations that aim to promote them.

New cheese packaging decomposes in 300 days, not 1,000 years: 'The solution was in the cheese itself'

As an alternative to single-use plastic wrapping, Ogilvy Colombia and Nestlé Central America have created “Self-Packing Cheese.”

The new biodegradable film is designed to decompose within 300 days of disposal — in stark contrast to the estimated 1,000 years it takes for standard plastic to break down.

And it’s entirely made from cheese waste and whey
.


Now that's brilliant!  Admittedly, we tend to buy block cheese or shredded cheese rather than slices, but lots of people prefer slices.

New butterfly species wows scientists: 'This discovery reveals a lineage shaped by 40,000 years of evolutionary solitude'

The Satyrium semiluna, or half-moon hairstreak, is a small gray butterfly that looks like a moth at first glance. The wildflower lovers are widespread across North America, from the Sagebrush steppe to the montane meadows of the Rocky Mountains.

But tucked away in the southeastern corner of Alberta, Canada, another colony of butterflies flaps across the Blakiston Fan landform of Waterton Lakes National Park.

Until now, they were thought to be a subpopulation of half-moon hairstreaks — until scientists made a phenomenal discovery: They were a new species of butterfly that had hidden in plain sight for centuries.

The researchers, who recently published their findings in the scientific journal ZooKeys, defined the new species as Satyrium curiosolus

This 5-star island paradise doubles as a sea turtle rescue

In Malaysia, five islands form Tunku Abdul Rahman Marine Park, a glittery turquoise oasis filled with coral reefs, parrotfish, seahorses, and green sea turtles.

Gaya, the largest of the five islands, is also home to the Gaya Island Resort: a luxury 5-star retreat nestled in an ancient rainforest that boasts stunning sea views, swim-up pools, and a spa village hidden amongst the mangroves.

But when guests have free time — between relaxing on massage tables and eating teppanyaki, shabu-shabu, and nabe — the resort challenges visitors to partake in local marine conservation efforts.



Ecotourism is a good way to get people involved, and maybe they'll want to stay involved.

French Polynesia created the world’s largest marine protected area

At the U.N. Ocean Conference this week, French Polynesia announced the creation of the world’s largest marine protected area, covering nearly 5 million square kilometers, or over 1.9 million square miles. It also plans to add another 500,000 square kilometers by next World Ocean Day.

Of that area, 1.1 million square kilometers (424,712 square miles) will be designated as highly or fully protected, meaning only traditional coastal fishing, ecotourism, and scientific research are allowed
.


It's a step forward, but my standard of FULLY protected means "humans don't go there." That's what is required for many edge-sensitive and disturbance-sensitive species. On land, if there is so much as a road through it, those species will avoid the area even if there are no vehicles using the road most of the time.

Here's another post about the insect apocalypse, including a trophic cascade devastating other species especially insectivores.  This one proposes electromagnetic radiation as a causal factor, which may or may not be true, and is not being studied.  It would be nice if that were a cause, because it is a factor under human control and thus could be fixed.

‘Half the tree of life’: ecologists’ horror as nature reserves are emptied of insects
A new point in history has been reached, entomologists say, as climate-led species’ collapse moves up the food chain even in supposedly protected regions free of pesticides.

They include in Germany, where flying insects across 63 insect reserves dropped 75% in less than 30 years; the US, where beetle numbers dropped 83% in 45 years; and Puerto Rico, where insect biomass dropped up to 60-fold since the 1970s. These declines are occurring in ecosystems that are otherwise protected from direct human influence.
[---8<---]
At one research centre – falling within a 22,000-hectare (85 sq mile) stretch of intact forest in Panama – scientists comparing current bird numbers with the 1970s found 70% of species had declined, and 88% of these had lost more than half of their population
.


As the insects die off, everything that eats them -- birds, amphibians, reptiles, etc. -- suffers a decline also.

Science Newsfrom research organizations

Anthropologists have examined the societal consequences of global glacier loss. This article appears alongside new research that estimates that more than three-quarters of the world's glacier mass could disappear by the end of the century under current climate policies.

Their article appears alongside new research that estimates that more than three-quarters of the world's glacier mass could disappear by the end of the century under current climate policies. While the study projects the physical outcomes of glacial melt, Howe and Boyer highlight the social impacts and human stories behind the statistics -- from disrupted ecosystems and endangered cultural heritage to funeral rites held for vanished ice.

Scientists believe penguin poop might be cooling Antarctica — here's how

In a paper published on Thursday in the journal Communications Earth and Environment, they describe how ammonia wafting off the droppings of 60,000 birds contributed to the formation of clouds that might be insulating Antarctica, helping cool down an otherwise rapidly warming continent.

New 7-mile-long underwater sculpture park invites snorkelers to save coral reefs

With construction starting this year, the Great Florida Reef will soon feature a 7-mile public art installation: The Reefline.

Both a sculpture park and a snorkeling trail, the development will also serve as an artificial reef to offer shelter to fish, which will, in turn, help corals thrive.

Hundred-year storm tides will occur every few decades in Bangladesh, scientists report

With projected global warming, the frequency of extreme storms will ramp up by the end of the century, according to a new study.
For the highly populated coastal country of Bangladesh, once-in-a-century storm tides could strike every 10 years -- or more often -- by the end of the century, scientists report
.


Oh, it's worse than that. Sunny-day floods will wipe out coastal settlements long before the dramatic storms do.

... was on April 3.

On April 3, 2025, Jane Goodall — the renowned environmentalist, conservationist, and activist — celebrates her 91st birthday.

To celebrate, the Governor of Colorado, Jared Polis, declared a new holiday: Animals Matter Day.

Researchers' breakthrough method reveals clouds amplify global warming far more than previously understood

Better technology to prepare for climate change.
Tropical marine low clouds play a crucial role in regulating Earth's climate. However, whether they mitigate or exacerbate global warming has long remained a mystery. Now, researchers have developed a groundbreaking method that significantly improves accuracy in climate predictions. This led to a major discovery -- that tropical cloud feedback may have amplified the greenhouse effect by a staggering 71% more than previously known to scientists
.


This is another example of the common pattern where scientists drastically underestimate how screwed we are.

'Thriving ecosystem' of creatures found in a previously unseen seafloor

Scientists discover thriving ecosystem after city-sized iceberg breaks away from Antarctica.

Sea spiders, octopuses, and icefish have been found thriving on a newly exposed seafloor, which is also home to giant corals and sponges. Researchers can now see all the creatures that call it home after an iceberg broke off near the Antarctic and exposed the ecosystem below
.


While it's possible for underwater currents to carry nutrients, my bet is the ice itself. It can carry a lot of nutrients from land, either picked up from soil or deposited from wind. That bottom layer is melting as it its the water, so whatever is carried by the ice will be released for the use of nearby organisms.
