The climate is not something that you can wait for particle physics style 5-sigma certainty on
Yes, yes it is. The most relevant observation so far is that there's been no statistically significant warming for the past 18 years. The reason it's the only observation you should concern yourself with is because the amount of CO2 going into the atmosphere has continued to climb. This does tend to falsify the hypothesis that CO2 is a significant driver of climate.
There's a considerable opportunity cost to spending trillions of dollars on a problem that you have no control over anyway (natural variation).
