The real practical solutions are trivial, the politics are not. It's a collective action problem, where the US is one of the actors.

Yup.

Plenty of solutions, but politicians will never make it happen.

We calculated that capping personal emissions (mostly doable via peer pressure should we get this moving as normal people) to some top 1 percent 25 metric carbon ton and going plant based would get us net-zero while additionally getting rid of the zillionaire problem and adding extra 50-100 gigaton rewilding effect to the table.

With no bigger than marginal effect on anyone's QOL.

But we're SOL as the propaganda machines of the zillionaires keep dividing normal people to fake dichotomies.

Whenever you hear a politician say "carbon neutral by 2050", interrupt them. The real goal is to avoid getting too far over 1.5 degrees warming. We need to avoid reaching tipping points that will cause non-recoverable damage to the earth system. The year 2050 is meaningless. Actual global average temperatures is what should be measured.

Then I'd be far more worried about nuclear war than minor temperature excursions. Aside from that "non recoverable" damage happens every day. What do you think mining is?

On average it was 10 degrees Fahrenheit cooler last year than it was the previous where I live in northern CA.

2050 is not meaningless. Its close enough to feel like its achievable but far enough away that you can put off immediate action and still feel there is time to get it done. Reminds of the lyrics of the spirit of the west song: It's a ways outside of town But the distance has its uses Close enough to make the effort Far enough to make excuses. https://www.youtube.com/watch?v=jZXgl5KxUQY

Hah. Shall I present it to you on a silver platter then? If you read the NASA page, they explicitly cite GHCNd, a raw surface temperature and precipitation dataset that goes back quite far. There's many other similar datasets you can find if you're willing to look. Check out the readme for the csv format description, and /by-year for the raw rows: https://www.ncei.noaa.gov/pub/data/ghcn/daily/

picked four stations at random[0] and it's just precip numbers, no temps, no humidity, no insolation, etc.

are you sure you linked what you think you linked?

[0] /by-station and then unclutched my scroll wheel and spun it for arbitrary amount of time, re-engaged clutch and clicked what was under the cursor. repeated 3 more times. i did a fifth, where the one i was looking at was identical to the fourth one, but had a 1 in the least significant portion of the station ID instead of a 4, in case it was like, "4" is precip, "1" is temps, and i happened to click "4" 4 times in a row.

If you initially make factually wrong comment then you should at least apologize and say that you are sorry for being wrong, not keep pushing your agenda further.

it’s right about the article.

Your behaviour is both incorrect (you were shown at the specific place) and intentional (you have ignored that). So, I have downvoted all your posts in this topic because I have observed the efficiency of the correct words to your ignorance. Usually I am glad to argue about the climate topic, but sometimes downvotes work better.

Which was, stop using CFCs, and stop venting them into the atmosphere to "dispose" of them. We also stopped lighting rivers on fire for mostly the same reasons, stop dumping industrial waste in them.

Ocean shipping produces more pollution than most countries. There are only like 5 countries that produce more carbon than the worldwide shipping fleet. If they cared then "cheap crap from China" wouldn't exist.

It's a scam. They want to monopolize the economy and they're using your environmental consciousness as the wedge to push you against your own best interests.

I’d love to see the raw data.

And what will you do with the raw data? Are you trained in processing and interpreting it? How good is your math?

you're right this is much to complicated and important for anyone to understand. just take our word for it that we have to make things more expensive, raise taxes, and restrict freedoms to fix it.

30 years ago I attended a university lecture in an economics class and the professor spoke about the economic consequences of global warming - some places will be better off and plenty of places will be worse off. There will be water shortages in some places, while heavy rainfall in others. He presented it as a given fact that the global warming is coming - and pretty much the whole audience was shocked. Finally someone asked if he really thinks that it is unavoidable. And his answer was yes, that is human nature. As long as fossil fuels are there and cheap to explore someone will use them.

30 years later it looks like he was right.

Edit: the IPCC was founded in 1988 thus people started in the 70ies to understand that there will be a problem but there was a very long period of inactivity. Personally I am quite optimistic that fusion will become commercially available before 2040.

And dear downvoters, dont shoot the messenger.

Drive less.

CO2 output per person in the US (all sources including industry, etc): ~13-14,000kg

Average distance driven per year per capita in the US: ~20,000km

Average CO2 output of current private vehicle fleet: ~250g/km

Therefore, over one third of total CO2 output per person is personal vehicle use. Considering only CO2 output due to personal choices driving has to be well over half.

Most people don't - or refuse - to consider the obvious choice to take personal responsibility. Drive less.

Stratospheric aerosol injection is the leading geoengineering proposal for a reason. If you have well-supported reasons to be skeptical, you should share it, but just saying "idk doesn't sound right to me" isn't convincing.

The amount of aerosol you need to I next is enormous, it needs to be sprayed at an altitude higher than realistic means of injection are feasible, and it has to be done in a way that doesn’t produce so much CO2 that it defeats the point. Can you imagine an extant tech that can come close to doing that at the required scale? I can’t.

High altitude solar drone gliders that collect low level water vapor and spray it to form ice.
