you forget that in the fossil record, we're not just looking at a single slice of time; we can see what taxa were present (subject to taphonomic filtering, natch) at various points in time. we're not stuck estimating ages of divergence based on molecular clocks; a lot of the time we can actually go back through the strata and SEE DIRECTLY where the two taxa first become morphologically/ecologically distinguishable. (yes, we have no way of separating cryptic species, but at the genus and family level it works just fine.)\
we're still cautious about saying "X is the direct ancestor of Y" instead of "X diverged from this lineage shortly before Y did", but we've got more tools at our disposal than you give us credit for.

>Executive Intelligence Review
You DO realize that EIR isn't actually a peer-reviewed journal, right? It's literally Lyndon LaRouche's newsletter.
this sort of thing is really just cargo cult science. people make pretty figures and format their write-up to look like a journal article, but fail to make the document meaningful and rigorous.
>CO2 always goes up AFTER temperatures
the graph you posted clearly shows temperature increasing AFTER a big increase in CO2 emissions, you brainlet.

>You accused me of referencing scientists that tampered data.
No, you illiterate. I accused you of referencing studies with unreliable data, and provided evidence to show that the data had been affected by contamination of the measurement sites.
I also accused you of hypocrisy, when you insisted that data obtained through an unreliable and inaccurate method should simply be adjusted slightly (if anything) rather than excluded from the analysis (when you accuse climatologists of tampering when they adjust for measurement error). And you've been trying to dodge that ever since by misrepresenting what I said. (You know, LYING.)
