Spending billions for no return: AGW alarmism going the way of the Y2K panic

I have yet to come across a case where Alarmism and the invocation of the Precautionary Principle to spend billions has been justified. The Precautionary Principle itself is flawed and is  usually invoked to justify actions in favour of  a political ideology which go against common sense. There are no principles involved.  For example the billions spent on “preventing” the alleged Y2K meltdown were shown to have been essentially unnecessary  when countries which just did not have the money to spend suffered no significant ill-effects (Ukraine and Romania for example).

The Precautionary Principle: An activist is walking down the street snapping his fingers continuously. A guy stops him and asks, “Why are you snapping your fingers all the time?” The activist answers, “To keep wild elephants away.” “That’s ridiculous!”, says the guy. The activist replies, “Oh, yeah? You don’t see any wild elephants around do you?”

The AGW othodoxy is following the same path where trillions are being spent in following political objectives which have no basis and go against common sense.

Professor Richard Lindzen of MIT has been addressing the UK House of Commons.

The Independent: Is catastrophic global warming, like the Millenium Bug, a mistake?

At a public meeting in the Commons, the climate scientist Professor Richard Lindzen of MIT made a number of declarations that unsettle the claim that global warming is backed by “settled science”. They’re not new, but some of them were new to me.

Over the last 150 years CO2 (or its equivalents) has doubled. This has been accompanied by a rise in temperature of seven or eight tenths of a degree centigrade. The Intergovernmental Panel on Climate Change attributes half this increase to human activity.

Lindzen says: “Claims that the earth has been warming, that there is a Greenhouse Effect, and that man’s activity have contributed to warming are trivially true but essentially meaningless.” He said our natural body temperature varies by eight tenths of a degree.

He showed a Boston newspaper weather graphic for a day – it had the actual temperature against a background of the highest and lowest recorded temperature for that day. The difference was as much as 60 degrees F.

When you double CO2 there’s a two per cent change in the “radiation budget”. Yet two billion years ago, the sun was 20 to 30 per cent dimmer – and the planet’s temperature was about the same.

The Al Gore graph showing CO2 and temperature rising and falling in tandem showed that the release of CO2 from the oceans was prompted by warming, not vice versa.

He gave us a slide with a series of familiar alarms – melting ice caps, disappearing icebergs, receding glaciers, rising sea levels. It was published by the US Weather Bureau in 1922.

And one further element of the consensus: there’s been no increase in temperature for 15 years. …..

…. 

He also said that the IPCC needs “positive feedback mechanisms” to justify anything above a one degree C  increase in their predictions. But: “Observation points to small negative feedbacks.”

How to explain the procession of eminent opinion leaders – some even in our own Royal Society – who advance the tenets of catastrophic global warming? “It is science in the service of politics,” he said.

If Lindzen is right, we will never be able to calculate the trillions that have been spent on the advice of “scientists in the service of politics”.
