Someone posted this terrible meme, so I naturally wanted to dunk on them. Instead of clever comments like “how can we know when thermometers weren’t invented until 1850?” I looked into the actual data, like a scientist. However, everything I found confirmed this statement.
> Karsten Haustein at the University of Leipzig, Germany, says the last time Earth was this warm was in the Eemian interglacial period, around 120,000 years ago.

Guys, help me actually debunk this. I tried to comment “how do we know the weather 99 thousand years ago?” they sent me stuff about icecores and sediments which I didn’t understand and then I deleted my comment.

Nope, it's legit. Ice cores capture atmosphere so you can measure the amount of each gas and the year corresponds to the depth of the sample. Xenon is used for the temperature proxy because it doesn't react with anything, but it dissolves in water and the amount is dependent on the thermal equilibrium so the concentration in the atmosphere tells you the temperature of the ocean.

that captures ocean temperature in one area over a vague length of time, not atmospheric temperature on a specific day in the hottest measurable location. if it was 130 degrees in Arizona for a couple days 100,000 years ago, we'd have absolutely no clue

Black anon here. Can confirm. It's been hot af last week.

How do glaciers capture ocean temperatures?

This is true, and theres no way to back out of it.
And even today you cant do such a thing as to measure average global temperatures. The sampling is always poorly done, due to malice and incompetence. Like putting the weather stations at airports because thats where the european gen X researchers from devry university trying to save the world arrive to.
Absolutely no one was measuring something like global temperatures in the 1930s unless you mean a compendium of urban temperatures in provincial capitals of the british empire.
More complicated methods like ice cores and whatever have error margins 10 times larger than the effects they try to measure.

Humans were alive 100,000 years ago, and there's nothing to say they weren't burning coal or otherwise contributing to those temperatures. It's plausible that humanity has already gone through a lesser climate catastrophy which knocked them back to the stone age

I copied this on Facebook, let's see what my friends say. They always make me feel dumb for dropping out of uni.

humans had coal plants back then? glad scientists finally admitted it

Its design is consistent with a miner's hammer. One possible explanation for the rock containing the artifact is that the highly soluble minerals in the ancient limestone may have formed a concretion around the object, via a common process (like that of a petrifying well) which often creates similar encrustations around fossils and other nuclei in a relatively short time.[2]

don't you remember all the old data they deleted?

well? where's the source that are labeling?

>that captures ocean temperature in one area
That's why you take ice cores from multiple places around the globe. That's how you establish what the global average temperature is, especially since xenon is a well mixed gas.

>if it was 130 degrees in Arizona for a couple days 100,000 years ago, we'd have absolutely no clue
That doesn't matter in the slightest. Do you understand the difference between climate and weather?

>tfw you stop believing in basic science that oil companies were aware of back in the 1950s because you're "redpilled"
