If I understand this paper correctly, it compares the temperature and CO2 levels on geologic time scales:
> Atmospheric CO2 concentration is correlated weakly but negatively with linearly-detrended T proxies over the last 425 million years.
> To estimate the integrity of temperature-proxy data, δ^18O values were averaged into bins of 2.5 million years (My)
It makes sense. Over long time scales, other factors are more important.
Does the same apply to shorter time scales, like thousands, hundreds, or tens of years?

One possible way would be to continue releasing the CO2 at the current or larger rates. If then temperatures and the climate reverse to the state from 200 or 300 years ago then it means it's part of a natural cycle and humans had nothing to do with it.
