> Models in the past did not attempt to account for non-anthropogenic carbon emissions They're literally mentioned by the first IPCC report already.

Early IPCC reports, all the way up to AR5 basically threw their hands up when it came to permafrost emissions. They admitted we didn't have the necessary data yet and for the most part didn't account for it at all in their models Check out the 1.5C special report. Go to section 2.2.1.2, last paragraph says > The reduced complexity climate models employed in this assessment do not take into account permafrost or non-C…

The claim being discussed is not that they didn’t account for it, but that they didn’t attempt to account for it. Reading that text, I think they did, but chose not to include it (I guess because they didn’t need to to make their point and, by not including it, avoided opponents from arguing about the validity of the result based on uncertainties in those models)

Are you going for a record in bad takes? Your account is a month old and yet I recognize it on sight for the bs takes. Try a bit harder please.

My point is until it's peer reviewed it offers no value. Do you know how many papers are published that don't pass peer review?

I'm hoping the current oil-war will cause people to re-assess fossil fuel use as expense becomes untenable and we start choosing electric vehicles and renewables.. which will just become "normal" and oil can stick around for synthetic chemistry routes.

Agreed, it's a big sovereignty issue. Once a solar panel is installed it keeps working for 20+ years. It doesn't get cut off if there's a political problem that interrupts supply.

China is some years behind our industrial development then undevelopment, and is building an entire USA of solar panels every year or whatever - can we expect them to quickly reduce emissions soon?

I thought the world and civilization would collapse because of carbon emissions. It's either serious or it's not. If it's serious then it doesn't really matter right? It's like you're on a boat that sprung a leak and everyone grabs a bucket. But a few people choose to not help because it's not fair for whatever reason.

To your metaphor, their point is that if everyone is grabbing buckets while someone else is working to spring more leaks, maybe someone needs to set aside their bucket & stop the person springing leaks

FWIW my personal assessment is that this acceleration is both real and largely out of our control. Models in the past did not attempt to account for non-anthropogenic carbon emissions, but as we experience further warming, most especially in the Arctic, feedback loops and tipping points mean that this (carbon emissions caused by “natural” processes) are becoming more evident. This is especially sensitive because a la…

> direct air capture is the primary escape hatch We MUST MUST MUST stop burning things. Stop it. - We are still mining and burning coal. This is incomprehensible. US, AU, etc Eg: https://www.nacoal.com/our-operations - We are still subsidizing oil to around $1T/year, not counting oil wars. Yes it will take some grid and storage upgrades (US) and continue to embrace renewables. It would be cheaper than the oil subsidy…

> We MUST MUST stop burning things.

Yes, we must. It is so rare to see someone saying this in public. Thank you for this simple clarity.

Stop burning everything! Fossil fuel, wood, plastic, garbage, paper. Stop making methane.

We only need solar energy at 1 dollarcent or eurocent (it will get much cheaper still!!) and a little batteries for the convenience of using electricity when the sun does not shine.

In the north and south you need more solar panels in the winter than in the summer by a factor of 50. But that pays it back in summer when you have a squanderable abundance of free and clean energy. We can store that surplus energy in purifying drinking water, melting iron ore or aluminum [5], melting reusable plastics or purifying silicon ingots.

Storing surplus heat or cold in the ground is another luxury, because it is more expensive than 1 dollarcent or eurocent solar running a heatpump.

Wind and hydro are also more costly than solar so they are another luxury with worse environmental costs than pure solar cells.

We need to build Enernet, a peer to peer electricity net and internet between all buildings with power routers. for around 100 dollar per building. You buy and sell your house surplus solar electricity to the neighborhood where it can be stored in car batteries. See my Fiberhood white paper [2].

The issue with any significant steps to curbing the climate or environmental impacts with laws or treaties is always: But the economy. It creates an incentive where someone doesn't follow the laws, burn everything they can to accelerate their economy, and take industry from other countries. My proposal is thus: create a supranational treaty organization with a EPA like authority(or whatever the European equivalent is…

And what exactly would prevent a country like the United States to use its outsize resources to moot this org?

What a surprise with all the wars going on, and AI depleting Earth resources, what a change from about the pandemic era when everyone was into paper straws and cups and promising to be a better person, because that is what was going to change anything.

As we all know, global warming wasn't happening until AI data centers started being built. They are honestly a drop in the bucket

What about solar shades? Seems like a relatively quick and easy way to regulate solar input. It's nice too because you can quickly remove it if necessary.

Reducing sunlight to the surface means we lose solar power effectiveness and we need to use more power for artificial lighting to grow plants.

Most of the surface of the earth is covered with water...

What if we cover the ice caps, and cover parts of the ocean instead of messing with grow cycles of plants on land...

No reduction in solar power, no artificial lights to grow plants. What effects might that have on ocean life? (below a certain depth - probably nothing, so surface ocean life is what we need to look at).

Just my two cents... we got plenty of surface area we can cover and potentially not affect much at all for day to day for animals, plants, and humans.
