Do climate models work?
Nope, they can't predict squat. It is with '97%' certainty that any climate model prediction will be wrong within 3 to 5 years.
Tip: Always bet against a climate model/simulation - the odds be with you.
Why do they always fail? As they say, read the whole thing in Real Clear Science.
And which groups of people really like to embrace the doomsday alarmist predictions from climate models?
Hmmm...the list is large: green crony capitalists; politicians on the green cronies donor payroll; scientists paid by government funded green research grants; journalists addicted to doomsday headlines; green environmental organizations feeding on the wallets of the gullible; and, of course, guilt-ridden celebrities who are massive CO2 polluters (take your pick, they come in all stripes and flavors).
