Another “Rocket Scientist” On Global Warming
N
ASA’s James Hansen is the premier “rocket scientist” (he’s not one, really) jacking up the hysteria on global warming. But not all rocket scientists agree. Check this out:
I DEVOTED six years to carbon accounting, building models for the Australian Greenhouse Office. I am the rocket scientist who wrote the carbon accounting model (FullCAM) that measures Australia’s compliance with the Kyoto Protocol, in the land use change and forestry sector.
That’s David Evans, the guy who pretty much wrote the book on global warming for Australia, writing in The Australian last week. He’s reached a very different conclusion than Hansen & the Hysterics:
When I started that job in 1999 the evidence that carbon emissions caused global warming seemed pretty good: CO2 is a greenhouse gas, the old ice core data, no other suspects.
The evidence was not conclusive, but why wait until we were certain when it appeared we needed to act quickly? Soon government and the scientific community were working together and lots of science research jobs were created. We scientists had political support, the ear of government, big budgets, and we felt fairly important and useful (well, I did anyway). It was great. We were working to save the planet.
But since 1999 new evidence has seriously weakened the case that carbon emissions are the main cause of global warming, and by 2007 the evidence was pretty conclusive that carbon played only a minor role and was not the main cause of the recent global warming. As Lord Keynes famously said, “When the facts change, I change my mind. What do you do, sir?”
He then lays out and explains what we do know about global warming as “the most basic salient facts:”
- Scientists have looked everywhere and they can’t find a greenhouse gas signature. Without it, the greenhouse effect is not the cause of global warming.
- There is no evidence to support the idea that carbon emissions cause significant global warming. None.
- The satellites that measure the world’s temperature all say that the warming trend ended in 2001, and that the temperature has dropped about 0.6C in the past year (to the temperature of 1980).
- The new ice cores show that in the past six global warmings over the past half a million years, the temperature rises occurred on average 800 years before the accompanying rise in atmospheric carbon. (In other words, the hysterics are wrong on the whole chicken or egg thing.)
All this is common knowledge and the Warmies can’t refute them, although Evans acknowledges that Warmies will argue that the most basic salient facts aren’t particularly relevant. If you believe that, you’ll believe anything.
The new ice core data was known by 2003, but Al Gore produced An Inconvenient Truth in 2005 based on earlier ice core data that had become as defunct as a coal-fired computer. And for that he got a Nobel Peace Prize.
Evans puts the Warmie research price tag thus far at $50 billion, “and we have not found any actual evidence that carbon emissions cause global warming.” And what happens if we never do?
Hopefully the people who fathered this mess – Dems here, Socialist/Labor in Europe and Australia, and Greenies everywhere – will be rejected, shunned, tossed aside, ridiculed and maybe even tarred and feathered in a great show of petrol-symbolism.
Or they’ll just move on to their next great sham and continue getting away with it.
