Strange? you are stickler for the scientific method except when it comes to climate science?

I can't see that you are considering any evidence at all.

Look at the evidence.

It has been much warmer than today and not all that long ago. Mankind not only survived, it flourished and spread around the world.

The last interglacial period was warmer than today, arguably by 5 C. And it is not the only one warmer than today.

And recent research seems to indicate that CO2 definitely lags temperature. Warming causes CO2 to rise, not the other way around.

That's a lie.

Initially, I was caught up in the global warming fervor like so many others. But then I started asking questions such as whether or not the Earth has ever been so warm. Imagine my surprise to find out that it was quite a bit warmer just a few thousand years ago. And it didn't kill of man-kind. Rather, it was an enormous boon to the human race.

My position is based on historical evidence, not on hope.

And this is likely to not kill all of mankind but even the most optimistic models predict food supplies and water being impacted in the long run. Water alone leads to war (Egypt/Ethiopia or India/China).

Yes mankind survived after fleeing to warmer parts of the world and returning to the northern hemisphere after the younger Dryas. I am not disagreeing the impact might not be as serious as models are predicting but the thresholds for going either way aren't well understood. Hence why worst case scenarios must be taken seriously.

So include massive volcanic lava flows releasing incredible amounts of CO2 (vastly more than man can release) as a potential problem.

I mean I could pick hundreds of examples, do you want me to list them.
Climate change killed off civilisations in the Sahara (it used to be green) and the Indus Valley in what is India and Pakistan. Its also thought to be responsible for demise of many native cultures in south and north America.

The Sahara was green. That was when it was warmer than today. The Gobi Desert was forested. Northern Mexico was much greener. None of that is news.

It can also be argued that the cooling from the Little Ice Age played a part in the end of the Anasazi civilization, forcing them to move elsewhere, partially as the result that a cooler climate is, in general, a dryer climate.

And don't imagine just because a civilization moved that the climate somehow killed them off.

I kind of seeing responses on a spectrum,
Least worry - avoid building along the coastline and invest in desalination and alternative power
Worst case - start doomesday prepping

I suspect that the primary reason to avoid building along the coastline, at least in some places, is because of subsidence, often from taking out so much water, causing the land to sink. And, in some places, there would be concerns about tsunamis and about hurricanes.

Desalination might be useful, but hardly because of Global Warming. Other power sources might be useful -- we could certainly use more nuclear power.

Sea level rise from Global Warming would be about the least of those concerns.

And doomsday prepping? That has everything to do with fear of what others may do, not climate change.

I'm cautiously optimistic humanity will survive. But we might lose a few on the way.

1.5C climate threshold has been breached

Yet the response from the MAGAs will either be:

a) "But muh giant pickup truck..."

or

b) "Climate is not changing. Dem fires in Commiefornia are Gawd's punishment for wokeness".

This seems to be more of a political than scientific issue.

I'm not persuaded by observations that Earth's climate used to be much warmer in the past so what does it matter if it gets that warm again. It also matters how quickly the climate changes.
- With gradual change over a long period of time we should be OK.
- With sudden huge changes we're likely to be in big trouble. !

I'd rather be hit by a bullet that has been thrown than one that has been fired from a gun.

Based on the OP the determining factor in that is which political party is dominant.
