AGW never held water well enough to deserve to be called a theory.
Never was real science, just politics.
John Coleman, who co-founded the Weather Channel, shocked academics by insisting the theory of man-made climate change was no longer scientifically credible. Instead, what ‘little evidence’ there is for rising global temperatures points to a ‘natural phenomenon’ within a developing eco-system.
In an open letter attacking the Intergovernmental Panel on Climate Change, he wrote: “The ocean is not rising significantly.
“The polar ice is increasing, not melting away. Polar Bears are increasing in number.
“Heat waves have actually diminished, not increased. There is not an uptick in the number or strength of storms (in fact storms are diminishing).
“I have studied this topic seriously for years. It has become a political and environment agenda item, but the science is not valid.”
Climate expert William Happer, from Princeton University, supported Mr Coleman’s claims. He added: “No chemical compound in the atmosphere has a worse reputation than CO2, thanks to the single-minded demonisation of this natural and essential atmospheric gas by advocates of government control and energy production.
“The incredible list of supposed horrors that increasing carbon dioxide will bring the world is pure belief disguised as science.” [more]
Ahh, good ol’ seminar time. [cues-up PowerPoint]
The original hypothesis was global cooling (see also: nuclear winter). Didn’t catch on.
End the draft! No nukes! Viet Nam war ends. Yada yada yada. The New Left jumps into environmentalism to overthrow “the system”: ecology vs conservation vs anti-pollution, etc. (almost nobody knew what these things even meant back then).
Okay, now some space probes penetrate the atmosphere of Venus. Woo, runaway greenhouse effect in a CO₂-rich atmosphere. Hey, we have CO₂ here on Earth.
(What? CO₂ is plant food? Shaddap!)
(What? No water cycle on Venus? Shaddap!)
(What? No ocean currents on Venus? Shaddap!)
(What? Venus a lot closer to the Sun? Shaddap!)
(What? The Sun’s radiated intensity varies? Shaddap!)
Ignoring all of the above, and knowing that burning fossil fuels generates CO₂ …
Heyyyy, we can uuuuse this! (Well, we need something — all the other good causes are gone, and so is the USSR.)
(What? Yeah, yeah we could.) *snick* *shh* *snick* *ahem* Be cool. [straightens tie]
I, uhm, I mean …
OMG, capitalism and Western Civilization and stuff are causing CO₂ levels to soar, and the Earth will go into uncontrolled thermal runaway due to the greenhouse effect.
We’re all gonna fry or drown or die of malaria, if we don’t control everything!
Add AGW to the list of things justifying global socialist government (file under Environment).
Plot data demonstrating the promised apocalypse.
(What? Rats!) Okay, bend curve to make it look really scary. Make it look really ugly out where there is no possible data, yet. Don’t worry, we’ll have sold this white elephant wayyy before the real data puts us all in jail.
Build “models” that generate the desired curve. No need to establish valid physics to generate that curve, just make the output work. Trust me, it’s easy. We do it with budgets all the time.
Give that curve a cool name that even Progs can remember. How about “hokey schtick?”
(What? Ah, even better. Even Cana… uh, nevermind.)
Write grant requests. Starve.
Scare people! Grants come rolling in.
Gov’t throws even more money at the witch doctors … etc. etc.
Burn a few heretics. Chant “The science is settled!” until even you believe that.
(What? Not warming anymore? Crap!)
Did I say Global Warming? I, uh, we meant Climate Change.
Any bad weather is now caused by
demons capitalism, white men, and eating meat.
(What? Nah, stop there, otherwise the media won’t be able to sell this nonsense.)
No, the science is not settled. Real science is never settled.
However, pseudo-science can be scraped off your boot.
