What on Earth do you mean it doesn't specify time frames accurately enough?
You want accurate data like we're getting today from satellites?
The graphs you posted in your OP just seem to be whatever you can get without any rhyme or reason.
The reason why I posted the chart I posted is because the Earth appears to have been in a 100,000 year cycle for about 400,000 years. That means what's happening NOW is more likely to be following what has happened in the last 400,000 years than what has happened before.
When the dinosaurs were around CO2 was high. During different periods of Earth's evolution we've had different atmospheres. At one point there was no oxygen, and after certain mass extinctions oxygen has become more and more prevalent.
Looking at charts from the past 200 years is pointless because it's such a short amount of time. It's like looking at breakfast and trying to figure out where you'll be in ten years time.
You have posted the 100,000 year cycle temperature chart. Stuck, bizarrely between two two hundred year charts. With no explanation about what it actually means.
But if you want to use YOUR chart, then who freaking cares, it's the same as my chart.

Your chart. 120,000 years ago temperatures reached about -62 degrees. 240,000 years ago they reached -63 degrees, 320,000 years ago they reached -60 degrees.
Right now we're at about -66 degrees which is three degrees COOLER than in the previous cycles and SIX DEGREES cooler than what has happened before. Even though CO2 levels are higher.
Which A) suggests CO2 isn't all it's cracked up to be, it's not like CO2 goes up and temperatures go up automatically and instantly. And B) it suggests the world temperature could rise WITHOUT HUMAN INTERFERENCE, by at least three more degrees.
So, what would the world temperatures be right now had humans not industrialized?
