Why is it so difficult to answer three simple climate questions?

By Bob Carter, David Evans, Stewart Franks and Bill Kininmonth.
22 June 2009

Senator Steve Fielding recently undertook a well-publicised fact-seeking trip to a climate change conference in Washington.

Listening to the papers presented, the Senator became puzzled that the scientific analyses that they provided directly contradicted the reasons that the Australian government has been giving as the justification for their emissions trading legislation.
At the Washington meeting, Fielding heard leading atmospheric physicist, Professor Dick Lindzen of MIT, describe evidence that the warming effect of carbon dioxide is much overestimated by current computer climate models, and then remark tellingly: “What we see, then, is that the very foundation of the issue of global warming is wrong. In a normal field, these results would pretty much wrap things up, but global warming/climate change has developed so much momentum that it has a life of its own – quite removed from science”. Indeed.
And another scientist, astrophysicist Dr Willie Soon from Harvard-Smithsonian Center for Astrophysics, commented that “A ‘magical’ CO2 knob for controlling weather and climate simply does not exist”. Think about that for a moment with respect to our government’s current climate policy.

Quite reasonably, therefore, on his return to Canberra Senator Fielding asked Climate Minister Penny Wong to answer three simple questions about the relationship between human carbon dioxide emissions and alleged dangerous global warming.

Fielding was seeking evidence, as opposed to unvalidated computer model projections, that human carbon dioxide emissions actually are driving dangerous global warming, to help him and the public at large better assess whether cutting emissions will actually be a cost-effective environmental measure.

After all, the passed-down cost to Australian taxpayers of the planned emissions trading bill is of the order of $4,000 per family per year for a carbon dioxide tax level of $30 per tonne. And the estimated “benefit” of such a large tax increase is that it may perhaps prevent an unmeasurable one-ten-thousandth of a degree of global warming from occurring. Next year? No, by 2100.

It was our privilege to have attended the meeting between Senators Wong and Fielding at which these three questions were discussed between ourselves and the Minister’s scientific advisors, Chief Scientist Penny Wong and Director of ANU climate research centre Will Steffen.

The three simple questions that were posed were:

1. Is it the case that CO2 increased by 5 per cent since 1998 whilst global temperature cooled over the same period? If so, why did the temperature not increase; and how can human emissions be to blame for dangerous levels of warming?

2. Is it the case that the rate and magnitude of warming between 1979 and 1998 (the late 20th century phase of global warming) were not unusual as compared with warmings that have occurred earlier in the Earth’s history? If the warming was not unusual, why is it perceived to have been caused by human CO2 emissions; and, in any event, why is warming a problem if the Earth has experienced similar warmings in the past?

3. Is it the case that all GCM computer models projected a steady increase in temperature for the period 1990-2008, whereas in fact there were only eight years of warming were followed by ten years of stasis and cooling?

Why these questions go unanswered is no mystery.

It’s because the debate is over when it comes to human-caused (anthropogenic) global warming (AGW).

The AGW-zealots are far too busy racing to jump off the cliff of “cap & trade” schemes and “carbon tax” schemes to be bothered addressing questions that they have proclaimed “settled”.

Such clear questions cannot be taken seriously. That would risk allowing an old-fashioned concept like contradictory evidence get in the way of the completely failed theory (AGW)!

Can’t let that happen. Otherwise, POOF … away go all those politically-cozy “green solutions” to the AGW “crisis”.

There isn’t a single proponent of the AGW theory in ANY country who will seriously address those questions. Because to do so would admit to the scam.
