Right. One issue is that the US's glidepath towards low GWP includes significant HFO usage (which is a PFAS) rather than speedrunning natural refrigerants which are the only sustainable long term solution. So we'll likely have more warming, but less PFAS as a result of this, along with higher costs and more uncertainty. The focus needs to be on natural refrigerants though long term.

Those are parliamentary systems of government...

If a simple majority is required to rule, then logically two parties will form somewhere near 50% support. The fact that other parties have existed in the past is an exception to the logical conclusion of two party rule inherent in the design itself.

That's not how it played out though. Rural areas had higher death rates.

You're a bit less cynical than I am, so I applaud you for that. I'm not sensing mailce per se, but I've noticed the same pro-hydrogen content for years from this particular user and it's getting pretty wild considering the massive, observable growth in the EV sector and the proven viability. There will always be folks tilting at windmills, however. For me, I'm going to continue promoting walkable/bikable/transit focused communities with EVs as a backstop.

Hydrogen cars are dead and EVs won already. This pro hydrogen position has only ever benefited the fossil industry, and is laguhable considering the state of the industry in 2026 (gestures broadly at China). Their arguments are simply disingenuous (e.g. obviously efficiency doesn't matter because bikes are more efficient than cars, so let's all agree to use inefficient cars). Hydrogen will be a thing for some industries, but not cars.

Heat pumps easily exceed 2.5 COP. More like 4 in the UK climate. And gas isn't 100% efficient either. But yeah it's a wash or can be more expensive to heat with heat pumps where electricity is really expensive. It helps if we all conveniently ignore externalities like pollution and carbon too.

What are you actually advocating for here? Not electrifying and waiting another few decades for hydrogen? You come off as excessively defensive of the practically nonexistent H2 industry and excessively critical of electrification, which is basically the Shell and Exxon position. We don't have time wait for anything, we need to use the tech we have now to reduce warming. Where do we get the hydrogen in your world? Is it blue or green? Blue is just fossil fuels with extra steps and green doesn't make sense until we have significant excess renewables and already electrified the easy stuff (buildings) and then it might still make sense only for industry/shipping and niche stuff. H2 itself has a GWP of 11 or so, and we will leak quite a bit. So again, what are you actually arguing for? I can't buy hydrogen, period. I can't buy a hydrogen vehicle, or a hydrogen furnace, or a hydrogen anything. What do you actually think we plebs should be doing here? I already want green steel as much as you do.

Also to compress it, chill it, transport it, and store it, while avoiding leaks and fires. You're absolutely right though, first comes renewables (and a shit ton of batteries), hopefully in parallel some green steel and chemical processes, then heavy transit and the harder edge cases to electrify, assuming electrification hasn't already solved those issues by then. Talking about regular folks buying fuel cell cars is not realistic.

Yep, it's commonly called the "Idaho Stop". Spending less time in intersections is safer for cyclists, and to me the biggest benefit is shutting down drivers that complain about bikes not stopping completely (even though most cars roll through anyway). If it's busy cyclists still need to stop and wait like normal.

Yes in Colorado cyclists can legally treat a stop as a yield.

Looks like Boulder CO to me

Yep, mostly becuase cold climates are high latitude and they don't get a ton of free BTUs from the sun all winter anyway. An exception might be lower latitude, high altitude areas (just guessing). I'd also guess that people doing white roofs are more likely to do basic air sealing and insulation retrofits.

I'm not familiar with NordPool specifics but this is exactly right and is playing out in California and elsewhere too. Basically just the duck curve. Storage is all but required as solar covers 100% of midday load.

Is it a bribe or ransom? Trump is extracting favors by threat.

Temps should stay quite flat at net zero. Extreme weather will persist, but not get worse in theory.

Not sure where you're from, but in the US "training" is optional, the tests are worthless (I passed by driving around a parking lot with one stop sign and parallel parking in a space that could fit a bus), and the points barely matter. Humans kill >40,000 other a humans a year on US roads. "We" are absolutely ok with massive amounts of traffic violence, unfortunately.

Stop trying to sanewash this lunatic. Agreed it would have been much worse with a gun, but let's not pretend he had a change of heart and wanted to help.

Officials say Soliman planned the attack for a year, wanted to “kill all Zionist people” and told investigators he would do it again.

The IRA is getting gutted and Trump is trying to force coal plants to stay open. Even if Kamala did absolutely nothing, that would still be much better for the climate. 1.3% is not a big number.

Vance represents the tech bro "libertatian" wing with Thiel and those ghouls. Musk fits right in.
