I’d define the “correct” temperature range for the planet as when our planet had the highest crop yields

You do understand there is NO correct temperature? There are only better or worse growing seasons in ever changing areas of the Earth.
The Sahara and all of North Africa was once fertile and supported millions of people in the Mediterranean region with the crops and animals raised there.
You cannot go back, you can only go forward. No matter what any one does the Earth’s climate will continue to change all on its own. Then, there are comet strikes like 10,800 BC which altered the climate worldwide overnight, killing off most the mega fauna and ushering in the Younger Dryas event.
You cannot halt of alter this progression; you can only adapt and survive.
You and I are in agreement. My point to the global warming libtards is they fuss about warming when the past few thousand years of history (going back only as far as we have historical records of people’s lives) shows life was better when it was warmer than it is now. So we should sit back and enjoy it as it inevitably gets a little warmer for the next 2 to 4 centuries, before it inevitably gets cooler and people go back to literally freezing to death in Germany in August (like was sometimes done during the most recent cooling period a few centuries ago).
