Methane levels, according to Ice Core samples, go up and down, correlating to temperature variations, for the last, oh, four hundred
thousand years or so. The chart provided seems very cyclical to me.
I am wondering why, about a 110,000 years ago, there were high
methane levels, and high temperatures, when my grandfather didn't yet
have his SUV? And why, about 110,000 years before that, before his grandfather had a model T, we see another spike in methane and temperature level?
Hmmm. Ya think it might be Cyclical?
