The process they described took millions of years. Yeah, we're probably in a somewhat rare in-between point. That "point" is still unimaginably long.

- somenameforme 3y agoSediment cores show extreme temperature oscillations over far shorter time frames. This [1] is 5 million years of temperature reconstructions based on the Vostok ice cores. Keep in mind the scale, the difference between the peaks and valleys is 10 degrees celsius! But the really interesting thing is that that derived from this [2], which is Earth's temperature over the past 65 million years. Those previous extremes just blur, because now you're talking about a temperature difference of 20 degrees celcius, no ice on the planet, and giant beasts roaming in lush greenery. Greenery which was basically everywhere, even Antarctica!
