(2) With this basis, I have no reason to doubt the IPCC attribution statement is the current best estimate of reality.
(1) I'll take that as a yes, you do own a car. Interestingly, not owning a car in the interest of protecting the environment is "virtue signalling" rather than being virtuous. In the past I've found you brittle and a little condescending. Now add hypocritical. Environmental protection starts with each one of us, and every little bit helps. If you are not willing to do your part, don't expect others to do theirs.
(2) I was wondering if that would be your answer. So if I can reframe your answer in a way you won't like but is objectively true, you believe the science is not fully settled, there is 5% chance that human activity does not have a significant influence on climate change. That's very interesting, since everything you've written on the topic (that I remember) has conveyed the clear and unequivocal sense that the science is "settled," and certain, not (even only slightly) uncertain.
It strikes me that you and I believe almost the same thing (80% certain rather than 95% certain in my case) but choose to take vastly different meaning and speak about that interpretation in very different contexts.
