Not a fan of scientific articles, opinions of health organizations and articles disproving your point? Fine ... i'll make it shorter.

> It is not possible to maintain a healthy diet using sustainable low-energy sources of plant protein in place of meat.

Not true.

> Meat is not an optional part of our diet.

Not true.

> There have been plenty of studies detailing the dietary impact of vegan diets.

There have been. Some paid by meat industry, some peer reviewed and supporting my point.

Could you share some of those studies supporting your point?

Hello again :) You've previously rejected scientific studies, so this time I won't include any, and will keep this as brief as possible. If you'll find that you'd like some, ask and I shall provide.

> Which has already happened

True.

> and is irreversible as far as we know

Not true.

> change on the scale that would be needed to mitigate (there is no reversing, only mitigation) would require mass casualties, because it would require deindustrialization

A superlative suggestion, sir. With just two minor flaws. One, it's not true. And two, it's not true. Now I realise that, technically speaking, that's only one flaw; but I thought it was such a big one, it was worth mentioning twice.

> Yes, but we know what may improve our chances.

What would that be?

I don't believe there is anything we can do about the impending climate changes. In my opinion all we can do is learn, prepare, and adapt.

Sure we can. We can start spreading Serpentine rock on the Ocean's surface. We just need some billionaires to fund it. Serpentine rock, which is primarily composed of the mineral serpentine, has been considered in the context of climate change mitigation due to its potential to sequester carbon dioxide (CO2) through a natural process called mineral carbonation. This process involves the reaction of CO2 with certain m…

What about energy and emissions from mining, transport, grounding, shipping, dispersing it?

How does it look then?

While the floating ice in the northern Arctic has behaved as scientists and climate models expected in a warming world – that is, on an apparent terminal decline – Antarctica’s sea ice has held steady.

So now the lag in the Southern Hemisphere is going away, and the Southern Hemisphere is finally playing 'catch up' with the Northern Hemisphere. Except that in geological terms where thousands of years are the norm, those decades of lag are negligible, really.

“It is very much outside our understanding of this system.” This is what worries me: climate change leading to entirely new regimes that we don't understand and thus can't model or predict with any accuracy. You just can't build a seawall for a sealevel rise of between 50 and 300 cm somewhere in about 20 to 50 years. Or for heatwaves of maximum 35 to 45 degrees, precipitation of max 20-100mm/hour, etc. Climate adapta…

> This is what worries me: climate change leading to entirely new regimes that we don't understand and thus can't model or predict with any accuracy. People have been talking about that for a while, we're playing god right now but we have no idea what's coming. It's the same thing every time we try something with nature, what seems easy and simple turns out to have massive side effects we couldn't imagine because eve…

Meanwhile HN will freak out over some loose study about aspartame or nano plastics, but dismiss extremely sound research on climate change. Clearly brainwashed by decades of corporate marketing.

> Climate change is caused by pollution and overconsumption. We're perfectly capable to change that ... we just don't want to. Yes, we can turn rich countries into poor countries by taking away transport, energy, and protein from the working class, and there's growing support for that approach. But that approach also destroys most of the hope for technological solutions. And even if the richest countries did sacrific…

Would standards of living really decline that much if we didn’t all have mega SUVs and the latest years iPhone?

There is so much consumption that is absolute crap and could easily be cut out while honestly improving life.

>That's propaganda, and now you're getting somewhere. We already get 63% of our protein from plants. If we were to extend that to 100%, we could store our entire 1.5C carbon budget through afforesting and rewilding pastures, which would also help restore biodiversity. Protein is not created equally. It is not possible to maintain a healthy diet using sustainable low-energy sources of plant protein in place of meat. M…

Even if we accept that meat is not optional we don't have to eat so much of it. Most of Europe consumes 1/2 to 2/3 of the meat per capita as the US. China too. Japan consumes about 40% per capita as the US and they consumer a mix of meats that has much less climate impact. India consumes around 1/30th of the US in meat per capita.

The ethical skeptic talks about this: https://theethicalskeptic.com/

We know by direct measurements that the warming is largely due to greenhouse gases, because we can measure radiation inflow and outflow and see that greenhouse gases are stopping incoming radiation from being radiated out and we can see how much is being trapped.

We know it is the greenhouse gases because we can measure the wavelengths of the incoming and outgoing radiation and see from spectrographs of greenhouse gases that the outgoing radiation falls into greenhouse gas absorption bands.

We can tell that the increase in greenhouse gases over the last couple hundred years is largely from human burning of fossil fuels because the carbon in fossil fuels has a different isotope ratio than that of carbon in living or recently living things. (Volcanic greenhouse gases would also have a similar isotope ratio to fossil fuels but we have sufficient monitoring to detect and account for geologic greenhouse gases).

Republicans have made climate denial part of their identity. The US isn't capable of doing anything federally until the nation is reunified.

Look up Democrats' views on nuclear energy.

Don't be absurd. There is a ginormous difference between a party whose position is that climate change is a problem that we have to deal with but doesn't support all possible ways to deal with it, and a party whose position until recently was that climate change was a hoax perpetrated by China or socialists or others to destroy the US, and whose current position is that maybe it is happening but we should not take any action and in fact should increase our fossil fuel use.
