At this point, yes we have. But I still have hope. The fact that we are almost certainly in a fairly long term drop in worldwide temperature it will difficult to fudge the numbers like they have in the past.
And something that has been (almost) unreported: CO2 is good for plants and agriculture. I read that this effect is real and measurable. The planet we live on is getting greener. That should be a good thing. The farmers love it. The MSM hates it. That should tell you all you need to know about these scam artists.
