There is also the view frequently seen on slashdot that we don't need to worry about climate change because technology/human ingenuity/clever programming will provide a solution at some point before it all goes too seriously wrong.
In terms of unfalsifiability, it is up there with more obviously religious beliefs.
Having a semi-religious "faith" in the power of technology to save us is an error.
However, I would point out that sometimes efforts to reduce atmospheric CO2 look like a mindless sledgehammer attack on a big problem that also would be an error. I am all for unleashing significant resources and ingenuity to attack this issue in a broad and open-minded way. But when, for example, as a citizen of California I get a ballot proposition that would write into law that significant resources get plowed into carbon sequestration, still a very unproven technology, I do want to gag.
