They won't, because your numbers are bogus
Your numbers are bogus: Its not that they are not right, though they may be, it's because you left out the temperature numbers for the millenia before the year 1880.
What those numbers show is global warming and global cooling without CO2 increases or decreases.
RL, this is not to say that you may not have a case, its just that you need to factor out natural causes like solar variability before you place the blame on CO2.
And by the way, we've also got a hole in the ozone due to freon.
