Which is the point however, if the CO2 plays a HUGE feedback mechanic then the problem should be worse because of record outputs with less carbon sink abilties.
Yet there isn't. Though the problem with the historical records is... they aren't exact and a prone to alteration and interptetation.
For example the widespread denial of the europeon warm period because of "relative lack of data in non western areas."
Even though the data that does exist points to it being warmer in other places as well. The problem is, a lot of the historical data isn't really historical data but historical guesses based on climate models.
