But there is no way to confirm that those methods are accurate...

Yes there are. Scientists compare the measurements from both methods in the time when there's data from both. For example ice cores formed last decade should match direct temperature measurements from last decade. It's the same way the oldest rings from living trees are matched against the newest rings from tree fossils, and radiocarbon dating is checked against all of that.

That does not look very reliable to me, because that implies certain things are only affected by ambient temperature.

Btw, Can you tell me how ancient temperature is measured from ice cores? My lookup only says we can detect atmospheric composition, and not temperatures from the ice cores.

I make this prediction: In 5 years, we will have learned that the red line was in error, and the temperatures will be in the bottom half of the graph. I know this because every prediction of climate doom turned out to be false. Entire nations were going to disappear under rising sea levels. It has not happened. I'm not saying no land sinks, but sea levels are not rising rapidly enough to prevent Al Gore (author of "A…

Others have corrected your confusion between prediction and observation. Lets instead show what we have already seen, today, that was previously predicted.

Kiribati and Tuvalu have measurable loss of land due to rising sea levels that is impacting people today. About 80% of the Maldives Islands will likely be uninhabitable within the next 25 years. The Marshall Islands have lost 18 out of their average 200cm above mean sea level height - roughly 6% of its land.

We have seen massive glacial retreat even in just the past 10 years, let alone the past 50. This is happening the world over, and at a rate that is not previously seen in the geological record (happy to argue this, thats my background). We are seeing large ice loss and lack of matching accumulation over Antarctica and Greenland - two great places to observe large scale processes. We just saw the Arctic stay largely unlocked for sea ice/shipping last season. The sum of these will take a moment to kick in, but the failure of conveyor currents will kick us all in the arse quite significantly and likely within our lifetime, and we have already seen hiccups.

The Forest of Fontainebleau, just 50 km south of Paris, is burning, with Canada it's on the scene trying to contain it. Nearby highways and trains - some of the busiest of France - are cut. It is a temperate European forest, oak trees and beech. No AC is going to save European from that. In fact, it is American AC which is the main cause of it. They dumped all that energy and greenhouse gases and Europeans are the on…

That’s tragic, I love Fontainebleau. But it’s industrial civilization as a whole, not American AC. Cement is a larger contributor, for example.

Yes, I should recycle more. Meanwhile, it’s OK for politicians to invest in coal and build gas-powered datacenters, while the ultrabillionaires buy groceries in a private jet. Don’t worry about that, just recycle more! It is about time we stop blaming the individual at the bottom of the ladder for the problems of society. And let me preempt you: society isn’t made up of individuals, but it is much greater than the su…

Why does it have to be one or the other? 7+ billion small actions add up; power plants and datacenters are still at least partly about fulfilling consumer demand. Or to put it another way - which of those things is under our control? If one can do something more, then why not? Because billionaires? The climate doesn't blame anyone, it just exists; being to blame or not, doesn't matter when we're all in the same boat…

It’s a tough sell. The impact of you turning your AC a little bit colder or having a bigger car is almost unmeasurable on a global basis yet the benefits to you personally are probably pretty big.
