Oh and about those alarmist predictions that didn’t come true? No mention of those?How do you know the Earth fluctuated like that over millions of years? I mean, where you there?
Oh that's right. These estimates come from global climate scientists. The same people who unanimously agree that while the Earth has undergone huge fluctuations before man ever arrived on the planet, the release of billions of tons of carbon in the last 100 years of the industrial age has likely created its own climate fluctuation - severity TBD.
Volcanoes and cow farts don't help things either. We know this because climate scientists go to the trouble of studying these things. I asked them about your chart and they said it's absolutely accurate, and has nothing to do with the validity of current global warming trends. Which they study as a profession. They also told me that anecdotal examples and conservative straw dog arguments make them sad.
Was I there? Not in this particular life form.
