re: CO2
And yet, the endless shrieking about drowned coastal cities, world famines, mass extinctions, and all the rest is not propaganda, but perfectly reasonable discourse.
There are real issues in global climate, but the current global warming hysteria still, in my opinion, has all the signs of dogma on it, not least of which is outraged hostility toward any dissenting opinions.
A bit of perspective:
Poverty has killed far more people than pollution ever did.
