This is common knowledge, right? The Little Ice Age ended in about 1800. At which point, the Earth started coming out of the Ice Age and entered upon a warming trend which would be expected to last for several centuries, and then be replaced by a cooling trend, and a new Ice Age (big or little). This the pattern. It's been repeated many times. We have tons of evidence for it.
And STILL they shout Global Warming and blame modern industry!
