Otro cientifico se aparta......

de la histeria del calentamiento global (cuyo propagandista mas celebre Al Gore):

"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.
FullCAM models carbon flows in plants, mulch, debris, soils and agricultural products, using inputs such as climate data, plant physiology and satellite data. I've been following the global warming debate closely for years.

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?"

Pareciera que muchos ambientalistas y políticos de izquierda quieren hacernos creer que la idea de que el calentamiento global es causado por las emisión de CO2 es un hecho ya aceptado por la cientificos y los que se oponen son solo los lacayos del "gran capital" y las transnacionales contaminadoras.

Dado que es un "hecho" se justifica usar todo el poder del estado para detener las emisiones, sin importar las consecuencias que esto tenga sobre la economía y sobre nuestras libertades.

Por supuesto que esa no es la realidad. No esta probado que el calentamiento global es causado por la emisión de CO2. Y no existe consenso entre la comunidad cientifica sobre el tema, como lo demuestras las opiniones de este cientifico.

Pero es que se debe tener en cuenta que este no es un debate cientifico, es un debate politizado:

"The world has spent $50 billion on global warming since 1990, and we have not found any actual evidence that carbon emissions cause global warming. Evidence consists of observations made by someone at some time that supports the idea that carbon emissions cause global warming. Computer models and theoretical calculations are not evidence, they are just theory.

What is going to happen over the next decade as global temperatures continue not to rise? The Labor Government is about to deliberately wreck the economy in order to reduce carbon emissions. If the reasons later turn out to be bogus, the electorate is not going to re-elect a Labor government for a long time. When it comes to light that the carbon scare was known to be bogus in 2008, the ALP is going to be regarded as criminally negligent or ideologically stupid for not having seen through it. And if the Liberals support the general thrust of their actions, they will be seen likewise.

The onus should be on those who want to change things to provide evidence for why the changes are necessary."
