If a cautiously qualified probabilistic statement is your idea of arrogance then you might want to adjust your disapproval thresholds. I've been making pro-environment arguments since the 1980s and I don't care to be lectured to about some imaginary complacency that I don't actually feel, thank you.

I'm really quite annoyed by your comment because I've already been through years of climate deniers telling me how 'arrogant' I am ot think humans could change the climate/derail God's plan/whatever, so I don't need pro-environment people calling me arrogant for a cautious assertion lifted out of its context, where I went on to talk about the likelihood of disastrous outcomes in the same sentence.
