Historical CO2 level data is questionable. A lot of it is based on air pockets found in ancient glacial ice cores. The problem with that is gas can difuse through ice, especialy over long periods of time.
Yet, today, America's leaders are reenacting every folly that brought these great powers [Russia, Germany, and Japan] to ruin -- from arrogance and hubris, to assertions of global hegemony, to imperial overstretch, to trumpeting new 'crusades,' to handing out war guarantees to regions and countries where Americans have never fought before. We are piling up the kind of commitments that produced the greatest disasters of the twentieth century.
— Pat Buchanan – A Republic, Not an Empire
