You have to remember that in 4.5 billion years, our planet has only 45 years where rising CO2 levels in the atmosphere and the global average temperature both moved up at the same time -- 1975 through 2020.
And I am excluding the period from 2003 through mid-2015, when CO2 levels rose a lot, but the global average temperature barely changed -- i would call that a flat trend.
We also have rising CO2 levels from 1940 through 1975 accompanied by global cooling.
That cooling trend is gradually being revised to show no cooling at all. But those of us old enough to remember know that the 1940 through 1970s cooling trend spawned mass media articles about a coming global cooling crisis.
Most scientists did not make long term climate predictions in the 1970s, but a few who predicted a global cooling disaster, got a lot of media attention.
Why should a computer game that makes wrong climate predictions be called a “climate model” ?
The effect of CO2 on the global average temperature is unknown, so all claims are just opinions.
Having a super computer programmed BY PEOPLE does not change a computer game into a real climate model. Even if the people have Ph.D. degrees.
The computer games merely predict whatever the owners want predicted — their personal opinions converted into complex math.
There is no evidence in temperature measurements since 1979 that the climate sensitivity to CO2 (TCS) is over +1 degrees C. per CO2 level doubling. Doubling the Co2 level would take over 100 years.
And the effect of CO2 could be zero, since no one knows what happens from CO2 in the actual atmosphere -- which is NOT a CO2 closed system lab experiment using artificially dried air.
The only models I like are tall and slim, on runways. Those are real models.
The "global average" temperature numbers before 1979 have far from global coverage, and have been “adjusted” far too many times — not to mention all the wild guess infilling of missing data needed to compile a global average.
Those numbers are not worthy of real science before 1979 ahen weather satellites were used to collect data.
We know the global average temperature is higher today than in 1979, but the global average temperature has been generally rising for 20,000 years.
We know global warming happens without any influence from man made CO2 because we have 4.5 billion years of climate change from natural causes.
We also know from ice core studies that in the past 500,000 year, changes in temperatures led changes in CO2 levels -- meaning that changing temperatures CAUSED changes of CO2 levels -- the opposite of what is claimed ftoday, at least for after 1975.
Today it is impossible to claim that natural causes of climate change no longer matter, and man made CO2 is now the “climate controller”. But that is EXACTLY what is claimed for the imagined coming "existential climate crisis".
No attempt is ever made to prove the claim that CO2 controls the climate -- it is merely asserted that CO2 caused the recent warming. People who ask questions are punished with riduicule and character attacks.
Another bizarre climate change assumption is that the climate was “perfect” in about 1750, and any changes from that point are an “existential crisis.”
People living in the period from 1650 to 1750 thought their climate was too cold, but what could they possibly know about the climate they lived in ?
