Global Warmer Hoaxer James Hansen Once Pushed Global Cooling

NASA bureaucrat James Hansen, who has been making a pretty penny by helping Al Gore prop up the global warming hoax, is a veteran of the global cooling hoax popular in the 1970s.

Investor's Business Daily reports that a 1971 Washington Post scare piece entitled "U.S. Scientist Sees New Ice Age Coming" fretted that burning fossil fuels discharges particles into the atmosphere that reflect the sun's rays back into space. Emissions over 5–10 years supposedly "could be sufficient to trigger an ice age."

The NASA research behind this hysteria was supported by a "computer program developed by Dr. James Hansen," the same guy who now refers to those who won't drink the global warming Kool-Aid as "court jesters."

IBD comments:

It's clear that Hansen is as much a political animal as he is a scientist. Did he switch from one approaching cataclysm to another because he thought it would be easier to sell to the public? Was it a career advancement move or an honest change of heart on science, based on empirical evidence?
If Hansen wants to change positions again, the time is now. With NASA having recently revised historical temperature data that Hansen himself compiled, the door has been opened for him to embrace the ice age projections of the early 1970s.
Could be he's feeling a little chill in the air again.

Is it me, or does he not look like he could play the part of a Mad Scientist in a Zombie Apocalypse movie? Either that or the creepy mortician thats secretly helping the zombies to wipe out a small town.

Rasool used a computer program that Hansen wrote. That does not mean that Hansen agreed with Rasool's conclusions. If I borrow your pen, does that mean you agree with everything I write with your pen? More on what's wrong with the IBD editorial here.

So Hansen wrote a climate modeling program which predicted that fossil fuel burning would within fifty years, cause a "global cooling" that would lower the Earth's average temperature by six degrees and you believe that it is irresponsible for the IBD editorial staff to document this?

Hansen did not write a climate modeling program that predicted that fossil fuel burning would cause global cooling of six degrees in 50 years. It is dishonest of the IBD to pretend that he did.

I really doubt if there was climate modeling software in 1971 anyways. I must add my 2 cents here though...anyone who thinks that modeling software can accurately predict climate changes (I don't give a rat's ass how powerful the computer is or how sophisticated the software is or even how many variables are factored in) is truly a kool-aid drinking fool who should consider getting a lobotomy(scientist or not).

They were only quoting a contemporary article from WaPo. Maybe your beef is with them, but it is highly unlikely that such a gross misstatement could go unchallenged by Rasool or Hansen for about 26 years.

Of course there was a short-term global cooling taking place during that time and there were lots of predictions that it would turn into an ice age.

It appears that climatologists are quick to predict dire climactic change at the drop of a hat based on short-term climate fluctuations.

The WaPo story just says that Rasool used a program that Hansen wrote. It does not say that Hansen agreed with Rasool's conclusions.

Tim, fair comment.

I think the take-away message is that computer modeling is interesting and fun, but hardly rock solid. Most models in my (admittedly very limited) experience entail calculating smallish differences between whackng great terms, and thus are devilishly sensitive to, e.g., initial variables, boundary conditions, basis sets, and other assumptions.

In the thirties America built a machine that could predict tides years in advance. It eve predicted a tide level with FAIR accuracy decades in the future. (The old records were checked as a test of how well it could do this) So don't sell those fourty-year-old computers short, they took us to the moon!

Hanson DID write such a program, wheather or not it was the one mentioned, who knows? He made several speaches and wrote several papers on "global cooling" and was it's leading advocate. I know, because I heard about it all through the seventies, it was BIG. Almost as big as "global warming" is today.

But anyway, computer programs can be jiggered anyway you want, to reflect any reality you want to present. Let's say that you write a "global warming/cooling" program to project how the climate would be in a hundred years. You would use the data that you HAVE and adjust it by how you BELIEVE it would work. There is no dishonesty about it, only speculation.

Your comment is noted Tim. There is no conclusive evidence that Hansen approved of how his data was used by his colleague. I suspect that he did, but cannot prove it so I held back from that conclusion and that was not the source of my beef.

IBD made a conclusion from a likely proposition, but they don’t have conclusive evidence.

That’s them, this is my stance… This example shows the danger of relying on climate modeling. There are too many factors involved to predict all of the processes that affect our planet’s climatology (even with today’s technology). A possible decrease of six degrees within 50 years is ludicrous.

One shouldn’t jump to conclusions like panicking that humanity is destroying the planet. We’ve already been through the Population Bomb and Ice Age scares. Haven’t we learned our lesson yet?
