Yes, but fortunately we aren't talking about 10x increases in CO2 concentrations due to human activity,
Nor are we talking about such increases when humans, let alone our civilizations, were around at all.
leaving a large safety margin (increase in solar output has been much smaller in comparison).
Yes, of course! There are only two factors at play, and they are both directly proportional in their effects when they are changed. Someone call Climate Research and inform them of your astounding simplification of the climate system.
And you can go back to more recent figures where solar output was closer to what it is and CO2 concentrations were still several times what they are today without any runaway effects.
Like when? When were CO2 concentrations "several times what they are today" last? Oh, that's right, over 100 million years ago. Again, your ridiculously oversimplified take on climate science must astound your peers! That is beyond the fact that you're arguing with yourself, since I never claimed that there were any "runaway effects" in the first place. More of your 1337 mind-reading skillz letting you down again, apparently.
Have you ever even bothered to look at climate history?
MANY times. Have you? Is the best you can do a single Wikipedia reference? What did that take, all of two minutes? Do you even know what the fuck you're looking at with that single graph?
No misinformation, you just read it wrong:
Am I? Let's see...
"Despite the supposed environmental destruction, the world is experiencing less war, less conflict, and less hunger today than it has since the start of the industrial revolution."
Do we have less war today than during WWII? Yes. My point exactly.
Yeah, I obviously mistook "since the start of the industrial revolution" to mean "since the start of the industrial revolution", rather than what you actually were thinking when you wrote those words: "than during WWII". Unlike you and your awesome mind-reading skillz, I just have to go on what people say. I'm sure you understand.
After consigning fascism and communism to the dustbins of history
Someone better let the Chinese know that their current form of government has been consigned to the "dustbins of history". As for Fascism, it's alive and well in the US in the form of the corporatocracy/plutocracy enabled by current political "climate".
and liberalizing trade and migration, things have improved greatly for all of humanity.
A whole lot of humanity today would heartily disagree.
In different words, you don't have numbers,
No, in the same words, because that's PRECISELY what I said. Your failed attempt to spin the obvious is pretty epic there.
Yet, you still claim that there is a "consensus" that there is going to be global devastation unless we act now.
Only If you can quote where I made any such claims; otherwise, you're just practicing more of your uber mind-reading skillz.
You raised the possibility of a runaway greenhouse effect and used it to justify limiting CO2 emissions.
No, you completely misread and spun what I said. I brought it up SPECIFICALLY to cast doubt on it, and offered a lesser, but still significant set of criteria to justify taking SOME action; I didn't specify what action to take; you added that yourself.
I'm saying "that doesn't seem plausible to me because..." In response, you just say "I don't know" and attack my objection. Where does that leave us? Still with no evidence or rational argument that a runaway greenhouse effect can happen.
How many times do I have to say "I never claimed any such thing" before it sinks in?
Attacking my objections to your statements doesn't actually provide any more factual, rational support for your statements.
Since when did that stop you? Sauce for the goose, pal.
