Is that the side that always thinks itself intellectually superior, in command of the facts, looks more like the establishment that Galileo and others faced. He couldn't prove mathmatically that the Earth did move around the sun by the way. There really was no conclusive proof at the moment.
The essence of science is proving a positive not defending a hope for political reasons. It's clear the MMGW mob is too invested in the desire to control, tax, ration to consider the loss of logic in the absolutism of man made warming.
If large number of the science community claimed a near term asteriod impact based on statistical noise would it catch on as well? The argument could be made for massive investments in technology such as nuclear, ballistics etc. for such a probability. It's sure to happen, would the left support the hope that this research could "save the Earth"? Not likely, it would support all the wrong interest groups. Right now everything from Vegans to every top down planner has a stake in MMGW. It's all been made to fit eco extremism, note the silence for the most part on nuclear build out, it's all pie in the sky "solar" and "wind" for the fantasy vote of the left that cares so much to take something away then consider the math or facts. Asteriods are not self-induced "sin" that could mandate the levels of social control that MMGW religion can command.
"My dear Kepler, what would you say of the learned here, who, replete with the pertinacity of the asp, have steadfastly refused to cast a glance through the telescope? What shall we make of this? Shall we laugh, or shall we cry?"
There isn't a shread of fact to link CO2 to causal GW. Other factors are likely far more important than an abstract as if the Earth was enclosed by glass.
