I know exactly what it means, that is why I said it
correlation does not mean causation.
Not always, but in this case we have eight hundred thousand years of data that proves it.

the holocene optimium was a LOT hotter than today.
the Minoan warm period was a LOT hotter than today.
The Roman warm period, the early medivial, the late medieval...all hotter than today..
it is clear the Earth and especially the Northern Hemisphere are cooler today than 7,000 BP and we are in a cooling trend
yet the CO2 was lower...?
oh...one more thing...you keep saying '800,000 years'...the Vostok Antarctic Ice Core Record only goes back half that far.
In the plot of the full Vostok ice core record in the upper left, you might just be able to see that the middle graph (Carbon Dioxide concentration, green line) slightly lags the temperature by about 800 years on average. This suggests that the changes in temperature might cause the Carbon Dioxide changes rather than the other way around.
Where did you get the data for the other 400K years?
The chart is from NASA, it is explained in the video I linked. The data goes back to 800,000 years.

Most graphs only show the last 400k years just to make the graph smaller

Explain it in your own words.
Convince me you know whereof you speak.
I've already told you that NASA can't be trusted.
after all...you said that you'd studied the data and that you understood it.
Prove it.
LOL, the data speaks for itself, I do not have to prove anything to you.
Why do you expect me to prove something to you when you yourself have not proven anything to me. You keep linking these charts which show a shorter time scale which prove nothing in the overall long term trend. Not only that the data you are linking came from the same exact ice core samples gathered by the same scientists (some from NASA and some from other countries) that my 800,000 year chart came from.
So if you do not trust NASA you should not trust any of the data you yourself linked.
where'd the data come from?
400K is Ice cores...
what's the rest?
what are the proxies?
I already answered this question in my previous comment
All this data comes from ice cores, they have ice cores that are over 800,000 years old
Proxy temperature just means the temperature was derived from ice cores. Humans only started recording reliable temperature records starting in the 1880s

Proxy (climate)
In the study of past climates ("paleoclimatology"), climate proxies are preserved physical characteristics of the past that stand in for direct meteorological measurements and enable scientists to reconstruct the climatic conditions over a longer fraction of the Earth's history. Reliable global records of climate only began in the 1880s, and proxies provide the only means for scientists to determine climatic patterns before record-keeping began.
Examples of proxies include ice cores, tree rings, sub-fossil pollen, boreholes, corals, lake and ocean sediments, and carbonate speleothems. The character of deposition or rate of growth of the proxies' material has been influenced by the climatic conditions of the time in which they were laid down or grew.
see..that wasn't hard was it?
