You can't just say it's only X% so it can't matter much, unless you know exactly how the (incredibly complex) system works.
I'm no climatologist, but
And of course it ends right there
I don't believe they understand it all that well either. If they did there'd be many mroe answers, for now all they have are questions.
Because climate science is just that, science, it is not for example practical engineering which we know and love which is 100% understandable if you go deep enough.
I don't think there is a more chaotic system to understand, with data down in the noise, than climate science.
Of course they don't understand it all, it is continual learning and refining based on the scientific process.
I'm all about being green, but because it makes economic sense. Let's stop lying about it.
Only fools do it
only because it makes economic sense.
Our modern world is built on things that are done because it's a good idea, it's exploring new areas, it's creating more jobs in 20 years time, and/or because it improves our quality of life for us and our kids, and our grandkids etc.
Unfortunately the stupidity of politics and a largely scientific illiterate public requires the IPCC and other groups to make up silly hard and fast dumbed down fluffy guesses to sell the issue.
Like, "X degC rise will mean X meters of water level rise in X years, with X economic impact"
Or, "removing X percent of carbon, or X percent of cars from the road, will drop the temp by X degrees" blah blah.
Yes, a lot of it is bullshit, but sometimes you gotta bullshit and scare people in order to sell the greater cause.
But don't make the mistake of thinking that the smell of bullshit means it's not real.
