Year 4, Month 7, Day 20: Why Not Rent Out The Empty Space?
The Grand Island Independent (FL) notes the preparations underway in the Keys, arguably the communities most at risk for rising ocean levels:
Seasonal tidal flooding that was once a rare inconvenience is now so predictable that some businesses at the end of Key West’s famed Duval Street stock sandbags just inside their front doors, ready anytime.
“It’s really easy to see during our spring high tides that the sea level is coming up _ for whatever reason _ and we have to accommodate for that,” said Johnnie Yongue, the on-site technician at the fire station for Monroe County’s project management department.
While New York City’s mayor was announcing a dramatic multibillion-dollar plan for flood walls and levees to hold back rising water levels there, sea walls like those that encase the Netherlands wouldn’t help much in the Keys, as a lack of coastal barriers isn’t the island chain’s only problem.
“Our base is old coral reef, so it’s full of holes,” says Alison Higgins, the sustainability coordinator for the city of Key West. “You’ve got both the erosion and the fact that (water) just comes up naturally through the holes.”
The Keys’ plans for adapting to rising sea levels sound a lot like the way they prepare for hurricanes: track the incoming disturbance, adjust infrastructure accordingly and communicate potential risks to residents _ all, hopefully, without scaring off the tourists who treasure the islands for their fishing, Technicolor sunsets, eccentric characters and a come-as-you-are social scene that has attracted the likes of Ernest Hemingway, U.S. presidents and flamboyant female impersonators.
And who doesn’t relish an opportunity to dump on Rick Scott? July 2:
The challenges facing municipal officials in the Florida Keys are unique to their particular circumstances; very few cities anywhere in the world are built on thousands of years’ worth of accumulated coral, and very few are so profoundly vulnerable to the rising sea levels which are now considered inevitable consequences of the melting Arctic. These singular island communities are on the front lines of climate change; eventually all of humanity is going to contend with the impacts of a runaway greenhouse effect over the coming decades, and it’s not going to be pretty.
Key West’s readiness to face these dangers should be an example to those who use their political power to delay action and obscure the truth of global heating. For instance, Rick Scott, whose profit-driven anti-science ideology may enrich him and his cronies in the short term, while ensuring disastrous consequences for the state he purports to lead.
Mr. Scott is one of many conservative politicians who have made meaningful responses to the climate crisis all but impossible. This toxic mix of greed and folly is bad news for Key West, for Florida, and for us all.

I don’t have any good news, unfortunately. The Toronto Star addresses melting permafrost, calling it a “Time Bomb”:
…the physical changes already seen in northern landscape is telling, said Dr. Merritt Turetsky, a University of Guelph ecologist who participated in the permafrost study.
“The (International Panel on Climate Change) outlined several scenarios and we are exceeding the worst case scenario,” she said.
Turetsky began her research on Canadian permafrost in the late 1990s. Over the last decade, she travelled to a number of permafrost sites in northern Alberta and the Northwest Territories — and she’s seen the melting permafrost drastically change the landscape.
“In that short time, the transformations are quite drastic,” she said. “It literally turns a forest into a semi-aquatic pool . . . vegetation starts to slump, thaw and sink into the ground. Trees start to pitch. This is causing the landscape to change in ways that most of the community hasn’t quite recognized yet.”
She said “collapse scars,” where trees and other types of vegetation slump over and sink into ponds, are becoming an increasingly common sight across the Canadian North.
In Inuvik, Rodgers said the town has experienced “permafrost stumpage” over the last several years — eroding roadsides and ditches dug in the permafrost that quickly transform into large, gaping holes.
Turetsky said the risks posed by permafrost remain high if human-made greenhouse gases remain on pace.
With nearly half of the country covered by permafrost, the impact will reach beyond already affected northern communities in the coming decades if scientists’ predictions are accurate.
Turetsky said a limit on human-made emissions could help keep some carbon frozen in the permafrost, but added that she fears an enormous amount of damage has already been done.
“The analogy is that it’s a big train about to derail,” she said. “Once it begins, permafrost thaw occurs slowly but you can’t stop it. That lack of control makes anybody feel nervous.”
I do love this world with all its beauty and all its music. So sorry to see it go. June 28:
The language of scientific discourse tends away from emotional intensity. Even the most alarming of conclusions is couched in affectively neutral terms; a scientific description of the Hindenburg disaster might run something like “a near-instantaneous hydroxygen combustion reaction triggered the ignition of carbon compounds, leading to destruction of vehicular infrastructure and a statistically significant mortality rate.” Oh, the humanity.
This detached tone demands careful scrutiny, especially when the subject is something as potentially devastating as melting Arctic permafrost, which could release enormous amounts of greenhouse gases like methane and carbon dioxide into the atmosphere in a geological eyeblink. When an ecological scientist like Dr. Merritt Turetsky uses phrases like “drastic transformations” and “a big train about to derail,” the rest of us need to recognize that her measured words are the scientific way of shouting “FIRE!”
Ignoring the climate crisis would be the costliest mistake our civilization ever makes.

Year 4, Month 8, Day 15: This Is Mine. This Is Mine. All This Is Mine.
The LA Times, on another big attractive animal:
The world’s most endangered feline species may become extinct in the wild within 50 years, researchers say, a victim of climate change.
A new report projects that Iberian lynx could become the first cat species in at least 2,000 years to become extinct, researchers found, largely because of the decline of the European rabbit, which makes up 80% of the cat’s diet.
The report, published Sunday in the journal Nature Climate Change, warns that current efforts to boost population of the distinctive tufted-eared cat will only “buy a few decades” for the animal that was once abundant in parts of Spain, Portugal and France.
Rabbit populations have drastically fallen because of overhunting, disease and habitat reduction, researchers said, with climate change a major driver.
Bla, bla, bla. July 23:
If it were only “charismatic megafauna” like the Iberian lynx that face extinction due to the onrush of climatic change, we’d have far less to worry about — although news reporters oriented towards such splashy stories might not notice the difference. Far more troubling than the fate of a single wild cat species is the ongoing decimation of Earth’s most valuable natural resource: the biodiversity which has filled every available ecological niche on the planet with life.
The fewer life-forms present in a large ecosystem, the less resilient the ecosystem. For example, monocropped agriculture is terribly vulnerable; while factory farms may be able to generate huge quantities of food, a single invasive virus or insect pest can destroy their productivity completely. Earth is currently undergoing a mass extinction event thanks to human-caused climate change; the Iberian lynx and the polar bears are just the tip of a (rapidly melting) iceberg.
