This would have been a reasonable statement 30 years ago. Our understanding of the climate system has moved on a huge amount since then, and it's now absolutely certain (inasmuch as any scientific theory can be certain), not merely "plausible", that humans have had a major impact on the climate.
I would be interested in your views on nuclear fusion: clean, safe energy, with no radioactive waste. I worked in research related to fusion for a while back in the 1980's, when it was predicted that commercial fusion reactors would be available in about 2030. Hmmmm. Even then, I sometimes got the impression that fusion research was a big pit into which money was being shovelled.
