Just as a thought: It is frowned upon in every school of thought (especially in the liberal(!) one) to justify something wrong by the existence of errors elsewhere.
No one would come up with the idea to say: Car accidents are unavoidable anyway, so let's just do away with traffic regulations.
SUVs can’t be regulated, so it doesn’t matter how houses are built... the quality of the logic is the same.
That CO2 effect deniers always come from the liberal camp to nip the discussion about this logic in the bud is no surprise. Because their own school of thought would stand in their way.
There are engineers who simply consider the greenhouse effect itself to be nonexistent—of course without ever having understood what exactly lies behind that term. But the worldview sticks. Discussions with such people are more barren than the Gobi Desert. At the first inconvenient counterargument, they pull out the equivalent of the Nazi card, the "freedom-restrictor card," and the conversation is over.
And climate change per se and the human contribution to climate change are two different things. It is enough to look at the timescale on which climate changes occurred before the industrial revolution and on which they have been occurring since then.
We might build higher dikes here and be happy that the red wine gets better. But what about the poor souls on certain other coasts?
