(Whooee!) Now that the IPCC report has been basically accepted by prominent former CC deniers like GWB and PMSH, the CC denial community must finally accept science and get out of the way of progress.
Anthropogenic climate change deniers have been relegated to the lunatic fringe along with moon-landing deniers, 9/11 conspiracy theorists and those who claim there were really no dinosaurs.
The lunatic fringe doesn't get a seat at the debate table. When serious discussions are taking place concerning space exploration, nobody cares what the moon-landing deniers say. They're nutjobs and everyone knows it. To allow them into the debate would be laughable.
We know now that man-made climate change is real. Our PM is smart enough and politically savvy enough to distance himself from the deniers.
The moon-landing conspiracy theorists are harmless enough. The CC deniers want us to ignore science at the peril of our grandchildren. They aren't harmless nutbars.
There really is no debate and we need to marginalize big oil's bought-and-paid-for spokeslobby by ignoring their self-serving junk science. When they rear up, they need to be reminded that they now occupy a place with the Flat Earth Society.
We no longer need to debate those who want to fiddle while the earth burns. We can't waste the time it takes to debate them anymore than we can waste time trying to convince skeptics that the US really sent a man to the moon.
