how much cheap energy should we forfeit over the next few centuries to hopefully address this vague speculation about future global harm? There is a huge real human cost for making energy more expensive mostly, to the developing economies we'll just suffer slower economic growth but they can suffer health problems.
You don't think they'll suffer as the climate changes and sea levels rise?

I repeat IMO this is not a question about science but about government decision making priorities, and desire to control the private economy.
In the United States the only real reason anyone in government would want to regulate the private economy is if there is a financial capitalist gain outside of his career as a politician. The vast majority of people in the US government are pro-capitalism. They don't care about controlling the private economy, they care about either making money or answering to their constituents which are other money-making for-profit entities. You make it sound like there's this latent socialist bent to US politicians and that climate change is their chance to place ownership or control of the means of the production in the people's hands via the government, and that's just silly. All one has to do is look at history to see that.
Secondly,
IF we need to do something about this then do you really think that corporations will take the initiative to work this out by themselves in time to fix the issue? You yourself seem quite happy to not worry about this because before there are severe consequences you'll be dead. That's exactly the short-term thinking that corporations have. So they too have zero incentive. As long as they think they don't suffer why care about future generations?
So really if we need to stop our contribution to warming then you need to force corporations to do so, which in turn requires your hated communist government. We know this is true - again from history which you seem to like to not dwell on (as well as hypotheses) - because we had to regulate to get corporations to stop polluting the environment. What on earth makes you think they'd act differently in regards to global warming???

I am pretty confident that the human race will rise to the challenge when and if it ever becomes urgent (IMO it isn't yet).
Climate isn't like a thermostat you set and then an hour later the temperature is perfect. Scientists have been warning us for years about what we're doing to the environment and capitalists and conservatives keep telling us that the problem is in the future. All while they don't suffer. There's something disturbingly convenient about that attitude.
And yet again, look at the record: Smoking was fine and it didn't cause cancer. How did we know? Because the private corporations spent a fortune on indoctrinating the public using fake science to do so. Their incentive? Capitalism/profit. They didn't care if cancer rates went up. Why would they - they made money. But scientists kept warning about the dangers of smoking, and to those who smoked it was urgent, yet people in general didn't listen for a long time because of the for-profit indoctrination taking place.

As I have said MANY times we are in the late interglacial period where warming has occurred in previous cycles.
Change isn't the issue, the rate of change is.
The scientists in question create models for climate and then extrapolate that and see what happens. They use different tools to do so and curiously it seems that different people using slightly different methods not only come to very similar conclusions, but that those conclusions actually conform to the various means found to evaluate past and present climate. In other words; The Japanese pick a method to model climate and their model conforms to what you can see when studying tree rings in North America, and so on.
The models show that the rate of change is increasing, and that's the issue, because it implies that we're beyond a natural cycle of warming/cooling.

One track mind much? I was thinking more about new arable farmland in Canada, etc.
And as I was saying, those with wealth and power will survive warming quite well, which certainly includes a fair amount of Americans and Canadians. You yourself almost got to the same point when you pointed out that the cost of this will disproportionally affect the poor. To see how things tend to pan out you can look at hurricane Katrina and how it changed things. Now make that a slower process, but globally. The picture is pretty clear.
