We already know from the past 45 years of global warming, since the 1970s, that the "social cost of carbon" is negative.
Global warming and higher atmospheric CO2 levels are both good news -- there is no cost (except for the huge amount of money being spent in a hopeless effort to end the good news).
We can observe the good news:
-- The colder areas in the upper half of the Northern Hemisphere are getting the most warming -- good news for the few people who live there.
-- And there is also the beneficial greening of our planet, from more CO2 in the atmosphere.
The climate alarmists ignore that reality.
They predict a completely different global warming experience for the next 45 years.
The good news global warming of the past suddenly becomes imaginary bad news global warming in the future.
No explanation is given beyond "because we say so".
In every year in the past 45 years, the alarmists have been predicting a climate crisis ... as the actual climate gets better and better.
They use junk science to scare people.
Scared people can be easily convinced that a powerful socialist government is the only way to save the planet.
This is a power play, and it has been succeeding.
Because too many people believe always wrong wild guess predictions of the future climate are real science ... when they are nothing more than climate astrology.
Climate astrology used to empower leftist politicians and their governments.
