(Bloomberg) -- A group of US House Republicans warned House Speaker Mike Johnson not to repeal the clean-energy tax credits in President Joe Biden’s signature climate law, warning such a move could upend private investment in the sector and snarl ongoing projects.
The letter, signed by 18 lawmakers, indicates Johnson may not have the support to undo the Inflation Reduction Act if the GOP retains control of the House next year.

Notable here, the Republican appeal warning Speaker Johnson not to repeal isn't about benefit to future generations.
It's about current economics.

Still, any port in a storm ...
 
Not climate change but I don't want to start a new thread - and it is something else for insurers (and reinsurers) to think about when setting rates.

Dangerous L.A. fault system rivaling the San Andreas tied to recent earthquakes​


75


An aerial view of the La Cañada Flintridge foothills shows dust and dirt thrown into the air following a magnitude 5.9 earthquake from Oct. 1, 1987.

Monday’s magnitude 4.4 earthquake centered four miles northeast of downtown Los Angeles was modest but packed quite a jolt.

Although no major damage was reported, experts say the temblor was in the general area of a dangerous fault system — one they have long feared is capable of producing a catastrophic earthquake in the heart of the city.

The quake ruptured on a small section of a fault associated with the Puente Hills thrust fault system, which has long been cited as a major seismic hazard for Southern California because it runs through heavily populated areas and is capable of ....

That's the problem with these dam Democrats, always finding fault. [just kiddin'. Or am I ?]

S2,
Not sure if you had this in mind,
a few years ago I found a report that due to measurements from orbiting satellites they were able to determine that consistent with the buoyancy principle within plate tectonics,
drought in North America had resulted in the continent weighing less, and therefore floating higher in the molten rock below it.

Do you mean to suggest anthropogenic global warming may actually be stimulating seismic activity?

The image in #202 has me wondering about the composition of that what may be either ground fog, or a fault-line gas cloud. If the latter, Sulfurous?
 
Interesting - hadn't seen that report abt drought and the North American continent weighing less. Going to have to see if I can find it.

Earthquakes result from strain build-up from without and weakening from within faults. A generic co-seismic condition is presented that includes just three angles representing, respectively, fault geometry, fault strength, and the ratio of fault coupling to lithostatic loading. Correspondingly, gravity fluctuations, bridging effects, and granular material production/distribution form an earthquake triad. As a dynamic constituent of the gravity field, groundwater fluctuation is the nexus between the triad components. It is pivotal in regulating major seismic irregularity, by reducing natural (dry, or purely tectonic, stationary seismicity) inter-seismic periods and by lowering magnitudes. Specifically, to exert stress on the fault, groundwater does not need to reside deep in proximity to the locked fault interface, as it can work remotely. It can act mechanically-direct (MD), by a differential de-loading and superimposing a seismogenetic lateral stress field, thereby aiding plate-coupling, from without, or mechanically-indirect (MI) by enhancing fault fatigue, and hence weakening the fault, from within.

Perhaps that's enough of a nibble to find some useful substance.
The vaguest of detail I recall was that the continent was measurably floating inches higher, because it weighed less. Way less.
 
In 1972, before Earth's living human population reached 4 billion, there was talk of a "population explosion". It took all of human history, hundreds of generations for the population to near 4 billion by 1970.
In one human lifetime, from 1970 to 2024 the human population has more than doubled. Meaning
it took millennia to reach 4 billion, but just a few generations to add that much again. BUT !!
We don't hear much about "population explosion" anymore.

Perhaps Vlad Putin can "save" us. A nuclear world war should help reduce the population some.

Trump is not the only madman in the solar system. What's bafflingly alarming is how many millions of voting supporters he retains, even after a decade of Trump deceit and treachery.
Dozens of felony convictions. Party to bloody insurrection. & he's still in an MOE tie 2 months from the election.

Trump's a New Yorker. He's never been to Jones Beach? News flash: there's more beach at low tide. Do the math Donold.
 
Republicans have a prideful history of destructive antagonism against environmental investments.
President Carter had solar water heaters installed in the white house.
Solar water heaters have higher up-front costs, that pay for themselves over time in reduced fuel consumption.
So Carter paid the up-front cost.
When Reagan displaced Carter in the white house Reagan quickly had the solar energy investment removed,
so the exec. could return to non-sustainable energy consumption.

And now in the planet hostile style of the Reagan [R] administration, Trump [R] threatens similar.

Yellen warns that ending US clean energy tax credits would raise consumer costs​

David Lawder / Thu, September 5, 2024 at 11:53 AM EDT
RALEIGH, North Carolina (Reuters) - U.S. Treasury Secretary Janet Yellen on Thursday warned that any attempts to roll back the Biden administration's clean energy tax credits would raise costs for families and jeopardize new investments in U.S. manufacturing that are creating jobs.
Yellen told an audience at North Carolina's Wake Tech Community College that families across the country had claimed $8.4 billion in energy tax credits that would help them lower their energy bills long-term.
Republican presidential candidate Donald Trump has pledged to rescind many of President Joe Biden's clean energy rules for power plants and electric vehicles.

Scientists looked deep beneath the Doomsday Glacier. What they found spells potential disaster for the planet​

The scientists project Thwaites and the Antarctic Ice Sheet could collapse within 200 years, which would have devastating consequences.
Thwaites holds enough water to increase sea levels by more than 2 feet. But because it also acts like a cork, holding back the vast Antarctic ice sheet, its collapse could ultimately lead to around 10 feet of sea level rise, devastating coastal communities from Miami and London to Bangladesh and the Pacific Islands.

Helene May Signal a Whole New Level of Threat​

Hurricanes used to lose most of their power before making it as far inland as western North Carolina. But Helene wreaked havoc there. Future hurricanes may, too.
Paul Carroll

As much damage as Hurricane Helene has caused — and this one is really bad — it also sends a truly ominous warning about future storms because of something known as the "brown-ocean effect."

Atlantic hurricanes lose force as they move inland, because they no longer have access to the warm water that provided their energy in the first place. But Helene stayed far stronger than normal as it moved north.

The governor of Georgia said it was like a 250-mile-wide tornado as it moved through the state. Helene dumped more than 32 inches of rain on parts of western North Carolina and devastated the area. The state is some 450 miles north of the Gulf of Mexico and historically has just had to deal with the dying remnants of such major storms.

Why didn't Helene fade as quickly as prior hurricanes have? Scientists say the reason may be the "brown-ocean effect."

And they worry that future storms may mimic Helene, meaning we may have to now worry about a hurricane alley reaching well up into Appalachia.

The "brown-ocean effect" can occur when ...

I'm not yet ready to join Trump / climate-change denier crowd. But I wouldn't be too hasty to extrapolate from one data point. (sure is one Helene of a data point though)

"The Butterfly Effect" is the nickname scientists have given substantial consequences arising from seemingly inconsequential causes.
For example, global sea level rise is predicted by global temperature increase of only a fraction of one degree.

Not too sure of the climatological thermodynamics involved here. But as of early October, looks grim. And if early indications correct ... uh oh.
 
Global warming has stimulated

Last Chance Tourism​

October 3, 2024 By EarthWise
Glaciers around the world are shrinking or disappearing. Melting glaciers and ice sheets are the biggest contributors to global sea level rise and ice loss rates are continuing to increase. Even if the world somehow manages to meet the climate goal of limiting warming to no more than 1.5 degrees Celsius, the world will still lose a quarter of its glacial mass by the year 2100. At higher levels of warming, most of the world’s glaciers could be gone.

One result of this situation is that people are rushing to see glaciers before they melt. Places like Iceland are experiencing a booming tourism economy. Half a million people now visit Iceland for glacier tours every year. The shrinking and disappearance of glaciers has popularized a new kind of adventure travel called ‘last chance tourism.’

Like other types of adventure travel, glacier tours are not without dangers. An American tourist visiting a glacial ice cave in an Icelandic national park in August was killed when a frozen arch collapsed. Ice caves, formed by glacial meltwater, are known for their brilliant blue walls. Increasing meltwater can make these formations more prone to collapse.

Glacial tours in Canada’s Jasper National Park are quite popular. Tour operators have had to reroute trails to the foot of the Athabasca Glacier several times every season because of glacial melt.

Glacier tourism is a goldmine for the tourist industry but conducting and managing it is increasingly challenging. Meanwhile, people feel like it’s important to bring their kids to see glaciers because they may be the last generation that can go stand on a glacier.
