"The AGW warmmongers are precisely the people who for the last 20 years have been claiming the science is settled and we skeptics need to stuff a sock in it"
I don't doubt that there exists a % of AGW supporters who are claiming that 'the science is settled'. Misinformed individuals abound at both sides of this discussion, and their existence proves zilch regarding this AGW controversy.
"Our claim... ...is that if they lied about item #1 in order to advance a specific non-scientific agenda"
Please re-read my comment. What I'm saying is that the consensus that the article claims that existed before -i.e. that the Medieval warm period was only local to Europe- didn't in fact exist, so the implication that 'THEY' were lying to us is disingenuous at best.
"I've checked on a few papers and they ALL start with an assumption I KNOW to be wrong: Solar activity does not constitute the major component of warming on Earth. Run the thought experiment where you turn off the sun and see how warm the CO2 keeps it."
Misdirection, indeed, but it's all yours. Plus a big smoking straw dog. No scientist in his sane mind would ever say that the Sun is not what keeps the Earth warm. Please read what you wrote and tell me who is trying to misdirect whom.
"You expend scarce resource only in proportion to the combine damage*risk danger factor when compared to cose"
WTF??? Please rewrite that into something understandable.
"When there are serious questions about both damage and risk, and the cost is 10 orders of magnitude higher than either..."
Genius. So the cost of measures against AGW is 10 orders of magnitude bigger than the cost of possible consequences of AGW? You got that from one of the many papers you read on the subject, didn't you? Yep, bullshit, indeed.
" I present as an objective example the danger that near-Earth object of sufficient size to cause a Tanguskan event"
The Tunguskan event killed at most a few dozen people. If it had happened in a densely populated area the death toll would have been at most a few millions. A big tragedy, but life would have continued in the rest of the world almost as usual. AGW would damage our agriculture, destroy coastal areas -where most of mankind resides-, disrupt transportation, cause famines and wars... .
It goes without saying that a really huge space rock could exterminate us, but on the other hand we don't have yet the technology that would allow us to destroy/deflect/whatever one of these big rocks.
"Yet no one is seriously expending money on identifying such objects"
FYI: Yes, they are. There are several projects that are compiling a catalog of such objects and their trajectories.
