…and has been since Roman times. The latest tree ring study — which environuts laud when it backs their claims (watch for their backpedaling on the usefulness of tree rings as evidence) — shows the planet has been steadily cooling over 2000 years.
It was warmer in Roman and Medieval times — something any historian worth their salt could have told you based off of ships’ logs, the initial colonization of Greenland (when it was green), and the ability to grow temperate weather crops in places like Scotland during the Medieval Warming Period. No flooding islands. No massive inundation of coastlines (they were pretty damned close to looking like they do today.) Point of fact, agriculture flourished, populations increased due to better diets, health, and the ability to trade with markets near and far.
Is there climate change? Yes, and it’s normal! The only reason for the enviropanic now is that it is tied to a political goal — the restoration of state over individual and the creation of a new aristocracy to lord over it.
