I don't deal with what we CAN do, I worry about what is mostly likely to happen in the real world, as opposed to the Make Believe World.
I look at trends, versus Great Promises a decade ago. I look at what is feasible and practicable versus what has been happening for decades. I'm not impressed when somebody reduces their output by 1-2% a year when the models say it has to be 8-10%.
I try and find hard numbers, how much will this cost, and find nothing but airy fairy rosey burfle. I see the public not liking nuclear and wanting to shut that down. That not only takes an option off the table, it digs a hole in what needs to be done, as Germany if discovering.
Mostly I see political BS and PR. and I think it's clear we're going to run this experiment and find out what happens. The notion that the world is really going to cut CO2 emissions fast enough is simply not something I believe, at all.
