I’m not a confrontational person but if I saw him in person, I would absolutely tell him to go fuck himself.
Tweet from Russ Vought: The National Science Foundation will be breaking up the National Center for Atmospheric Research (NCAR) in Boulder, Colorado. This facility is one of the largest sources of climate alarmism in the country. A comprehensive review is underway & any vital activities such as weather research will be moved to another entity or location. 👇 Included is a link to a USA today story about the regime’s plan to dismantle NCAR.

Another insane move from the Trump regime.

One of NCAR's contributions to climate science is the development of the Community Earth System Model (CESM), which is used by researchers worldwide. Here's a simulation of air-sea CO₂ fluxes from CESM.

A four-panel Anakin Padme 4 Panel Meme arranged in a 2×2 grid. The panels show a conversation between two young adults. Top-left panel: A young man with short brown hair and light skin looks slightly to the side with a neutral, mildly confident expression. White, bold, all-caps meme text at the top reads: “WE’RE GOING TO STOP MAKING THE F-150 LIGHTNING”. Top-right panel: A young woman with light skin, curly brown hair, and a green floral headband smiles brightly, looking at the man with an expectant, hopeful expression. White, bold, all-caps text at the bottom reads: “BECAUSE BIG CARS SUCK AND YOU’RE ELECTRIFYING THE FORD FIESTA, RIGHT?” Bottom-left panel: A closer shot of the young man’s face. He looks forward with a serious, slightly tense expression and does not smile. There is no text in this panel. Bottom-right panel: A closer shot of the young woman’s face. Her smile has faded into a concerned, uncertain look as she stares ahead. White, bold, all-caps text at the bottom reads: “YOU’RE ELECTRIFYING THE FORD FIESTA, RIGHT?”

They can't make the bridge wider, and compared to paint, I think bollards are an upgrade.
Google Street View image from Lambeth Bridge in London. Traffic is moving in both directions; a truck with a blue mesh cage drives away in the left lane, while a black taxi cab approaches in the center lane. To the right, a classic red double-decker bus is visible in the background. The bridge features distinct architectural details, including black railings with salmon-pink lattice panels and tall stone obelisks topped with decorative pinecone sculptures. The pedestrian walkway is separated from the road by a low railing. There's a cycle lane separated from the car lane by white paint, offering no protection. On the right side of the riverbank, a large, modern building with a curved glass façade dominates the view, standing next to a taller red-brick office building.

People like Steve Bannon are fully capable of being rational. The extremism is just a grift. Here he is as acting CEO at Biosphere 2, discussing the global change research being conducted there.

I learned about the adaptors because I am discarding a lot of failed batteries but wanted to keep using the older tools with the new batteries that I have. It’s also annoying that I can’t just replace the cells in these batteries.
A collection of various post-style power tool batteries, predominantly black and yellow, some labeled with tags indicating their status (e.g., "Replace," "Bad"). They are arranged the floor with a textured surface.

This is why daylighting is essential if we care about Vision Zero. How is that white car supposed to see with that giant pickup truck parked in the way?

Proprietary battery designs are annoying. I just discovered that you can get adapters to use the same battery across different power tools, even with different voltages (they have built-in DC-to-DC converters) and different brands. Game changer!
A close-up, top-down shot of three different battery and adapters for power tools sitting on a light wooden surface. On the left is a small, black adapter marked "DW20VADPT" with a "DW20V" logo, which is a DeWalt adapter that allows a 20V battery to be used in another brand's power tools. It features slows on the top and bottom. In the center is a large, bright yellow and black DeWalt LITHIUM ION 20V 4 Ah battery pack, model DCB204. This is a modern, slide-style battery. On the right is a larger, mostly black adapter with a yellow base, featuring an upright, black male terminal post. The label visible on the side includes "DCA1820". This is a DeWalt 20V MAX to 18V Tool Adapter, designed to allow the modern 20V MAX batteries (like the one in the center) to be used with older 18V post-style tools. The adapter has a sliding connection slot on the bottom and a post-style connector on top.

Anything that leads to more fossil fuels coming out of the ground is bad news.
David Ho, an oceanographer and carbon removal expert at the University of Hawaii, argued in the journal “Nature” that carbon removal technology (like CCUS) should not be regarded as the solution to climate change “as if it somehow replaces radical, immediate emissions cuts.” I sent Carney’s MOU to Professor Ho, who responded that the MOU is not good news for anyone “who values a habitable planet.” “CCUS projects have a long history of failure, and even when they succeed, much of the captured CO2 is used for enhanced oil recovery ,” wrote Ho. “The MOU explicitly allows EOR, and anything that leads to more fossil fuels coming out of the ground is bad news.”

One reason Running Tide failed was that they lacked expertise in the ocean and they didn't care. Jón Ólafsson is an expert in the ocean carbon cycle around Iceland and the most respected oceanographer in Iceland, and this was the attitude of Running Tide's CEO towards Prof. Ólafsson. 🙄
The location where Running Tide dumped the Nova Scotian wood naturally “releases about as much [carbon] back to the atmosphere in winter as it fixes in the summer,” says Ólafsson, who published a peer-reviewed article on this very topic—carbon fluxes in the North Atlantic—in 2021. According to Ólafsson’s decades of research, it was physically impossible for the ocean to absorb carbon for more than six months in those locations. When told this information by WIRED, Odlin said he was not familiar with the scientists or the 2021 paper. “This is what academics do. This is what happens when people are stuck in institutions and don’t have to live in the real world,” Odlin said. “I could care less what that guy thinks.”

It’s good for you but a bad sign for the planet.

A blue area represents the normal temperature range, while a light green line indicates today's temperature trend throughout the day. The green line is completely outside the blue area.

Re-reading Daniel Epps and Ganesh Sitaraman's Yale Law Journal article on how to reform SCOTUS for no particular reason.

yalelawjournal.org/pdf/EppsSita...
THE YALE LAW JOURNAL DANIEL EPPS & GANESH SITARAMAN How to Save the Supreme Court ABSTRACT. The consequences of Justice Brett Kavanaugh's Supreme Court confirmation are seismic. Justice Kavanaugh, replacing Justice Anthony Kennedy, completes a new conservative majority and represents a stunning Republican victory after decades of increasingly partisan battles over control of the Court. The result is a Supreme Court whose Justices are likely to vote along party lines more consistently than ever before in American history. That development gravely threatens the Court's legitimacy. If in the future roughly half of Americans lack confidence in the Supreme Court's ability to render impartial justice, the Court's power to settle important questions of law will be in serious jeopardy. Moreover, many Democrats are already calling for changes like court-packing to prevent the new conservative majority from blocking progressive reforms. Even if justified, such moves could provoke further escalation that would leave the Court's image and the rule of law badly damaged. The coming crisis can be stopped. But saving the Court's legitimacy as an institution above politics will require a radical rethinking of how the Court has operated for more than two centu-ries. In this Feature, we outline a new framework for Supreme Court reform. Specifically, we argue for reforms that are plausibly constitutional (and thus implementable by statute) and that are capable of creating a stable equilibrium even if initially implemented using "hardball" tactics. Under this framework, we evaluate existing proposals and offer two of our own: the Supreme Court Lottery and the Balanced Bench. Whether policymakers adopt these precise proposals or not, our framework can guide their much-needed search for reform. We can save what is good about the Court- but only if we are willing to transform the Court.

Did you make sure to keep the camera away from the volcano like we discussed?

Yeah, about that…

Apparently people are once again asking who's at fault here. We can improve road safety dramatically by revoking the driver's licence of everyone who thinks it's the cyclist's fault.
