Mainstream NZ Herald – Balances Reporting

“Several aspects of Jim Salinger’s op-ed “Climate hurtling towards a hothouse Earth” (Herald 24/5/13) are quite misleading.

It is true most climate scientists would agree that rising carbon dioxide in the atmosphere due to fossil fuel use could affect global climate. The basic physics is there to support this view. But there is no evidence that the putative change would be large or damaging. Output from computer models is not evidence unless model performance has been validated. So far, it has not.

The so-called evidence of minor human-caused climatic change can also be attributed to causes or processes other than those related to the increase of carbon dioxide in the atmosphere.

What is rarely mentioned by climate alarmists is the incontrovertible fact that adding more carbon dioxide to the atmosphere has an ever-decreasing effect on global temperature. To illustrate this, compare covering a glass window with very thin paint. The first coat of paint cuts out some light, the second some more; but each subsequent coat has an ever decreasing effect on light shining through.

It is true, the warming effect of increasing carbon dioxide concentrations never reaches zero (saturation); but, for significant global warming to occur, increased concentrations must set in motion…. “
