Reply to comment by BurnerAcc2020 in Global food consumption alone could add nearly 1 °C to warming by 2100. Seventy five percent of this warming is driven by foods that are high sources of methane (ruminant meat, dairy and rice). by Plant__Eater
Climate action tracker explicitly measures policy and current action on emissions, not extraction, do they not? Based on their 'CAT emissions gap' visualisation, they seem to extrapolate current consumption emissions into the future to arrive at 2.2-3.4C by 2100. Is there a section of this (I agree, excellent) resource that tracks committed emissions against commercial disclosures?

Oh, we're not on the 2.7C trajectory, my dude. Check the commercial disclosures of fossil fuel extraction companies and the governments giving them permits. We're likely heading for 4+ or worse if we don't get a deus ex machina or a sufficiently large and sudden ice sheet slip. There's no sign of restraint on the extraction side.
Also check McGlade and Nature 2015, and Ekins' 2021 follow-up.

Reply to comment by AllanfromWales1 in Companies with climate change initiatives may be the biggest greenhouse gas emitters. Researchers say this supports the theory of companies 'greenwashing' with symbolic gestures rather than making material change that can help fight climate change. N = 600 companies from 35 countries. by MistWeaver80
And these are the same companies with the means to make changes. Does this paper seek to actually disentangle the enabling mechanism of success and the correlation between economic output and emissions from greenwashing?
Surely what matters is not just absolute emissions (but that also!) when considering greenwashing, but actual delta between baseline emissions and current emissions.

I added example citations. You can find more with a similar search string, like 'topical proteins food allergy theory', which is what I just used.

Perhaps my understanding is not correct? Have we not essentially figured out that the increasing frequency of food related allergies is related to the topical application of food derivative proteins in a largely functionless manner in cosmetic and cleaning products? Baby body encounters new protein in wrong context (like peanut derivatives in a skin cream), arranges immune reaction, then later deploys that reaction when the child finally gets around to eating that thing rather than having it rubbed on its skin?
Is that model not well enough validated, or is my understanding flawed?
If this is the major contributor, isn't this an easily soluble phenomenon by subtraction, rather than addition?

Reply to comment by Sevulturus in Fossil fuel producers pay for carbon clear up. Compelling fossil fuel producers to pay for carbon clean-up could end these fuels’ contribution to global warming without pitting climate action against meeting society’s energy needs—at a relatively affordable cost. by Wagamaga
Not even. Moneyed interests will first deploy a small portion of their wealth to eviscerate and oust the policy makers attempting to hold them to account. Those lawmakers so removed, business continues as usual.
Political action on global warming is demonstrably too slow without significant campaign finance reform in every large economy. No clue what you do for the large economies with authoritarians in charge, but I guess it's comparing two huge problems.

I mean based on the spectrum of xrays used, not produced.
My reference for this is photolithography, where the need for a very narrow band of xrays creates a huge problem. If a broader spectrum will do here, then OK, not a problem. Will a broad xray spectrum really do?

Neighbour, this is a science sub. Many of us attended universities or have worked at them or with them.
SemanticTriangle t1_izw77z6 wrote
50% capacity loss after 1000 cycles, requires Mo, which is only about 30% cheaper per kg than Li. 2/3rds of the theoretical energy density of sodium sulfur. Lots of engineering learning required to go from research to viability, and no strong record at University of Sydney for continuous process improvement or technology transfer to industry -- although I have not dealt with this school or group before and they might certainly be better. Not overly exciting as a candidate unless they show more.

Biofuels have an extremely poor record of carbon neutrality. I see Nature, so it's obviously legit, but is this concern addressed in the article?

Nickel iron magnets are strong but soft unless the crystal structure is very specifically ordered. By adding a little phosphorus, we can trick the nickel and iron into the right order to make them into a hard and strong magnet.

>The researchers developed a new battery structure that adds an ultrathin nickel foil as the fourth component besides anode, electrolyte and cathode. Acting as a stimulus, the nickel foil self-regulates the battery’s temperature and reactivity which allows for 10-minute fast charging on just about any EV battery, Wang explained.
Increase in cell complexity means increase in processing cost. Does it scale?

It's complicated, especially if your problem is high body fat percentage. Eating disorders are no joke, but controlling body fat ultimately comes down to controlling energy intake.
If you are just not active, then you start at the beginning. Either /r/fitness or /r/bodyweightfitness have beginner guides and faqs. But there's no easy or short road. You have to consistently put in the work and it's not easy.
If you have medical problems or pain you may need medical advice first, or to fix underlying issues, and those subs will not give medical advice.

It's reasonable to assume all of the normal caveats and side conditions apply, but it definitely makes the sentence less punchy. I guess all in all, it's easier to accuse me of ableism than to think about the vast majority of people in the OECD who age badly because they just don't make the time for it.
The statement isn't intended to be comprehensive. It's intended to be simple. Most people, especially able bodied people, think of old age as something that happens to them that can't be mitigated. There's a component of that, but for the most part it can be held off by being active. Even people with disabilities benefit from being as active as they can.
See how much longer that was to write?

That's the strange phenomenon explained. If you need to wash your mouth out, salt water or even just water will do.
