I have three children that make various 'sacrifices' to signal their virtue to Gaia and the uplifting of mankind. Bless their hearts cause I was just like them at their age.
Now I am older and know better. But I still go around behind them turning down thermostats and turning off lights.
It's one thing to talk the talk, another to walk the walk.
I'm very glad you are cynical in your old age... but the reality is, the science isn't in dispute. Much like evolution, it's not the science you have a problem with, it's the implication.
The science is definitely in dispute. Many or most of the doomsday predictions are absolute garbage.
I do believe in the warming influence of CO2. A minor influence. Everything thing else is hyped up and exaggerated.
Pick an area of research. The claims are unsupported by the level of certainty. I actually like science, so I am concerned about the damage being done to it in the name of 'The Noble Cause'.
