Scaremongers

Archdiocese of Sydney – February 18, 2007

This article is more of an open letter from Cardinal Pell, Cardinal Priest of the Title of S. Maria Domenica Mazzarello. It is interesting, not in the discussion of facts (as these are not really mentioned) but in the advice that weather and climate are quite complicated and we really don’t understand it enough to draw conclusions.

We have been subjected to a lot of nonsense about climate disasters as some zealots have been painting extreme scenarios to frighten us.

I am deeply skeptical about man-made catastrophic global warming, but still open to further evidence. I would be surprised if industrial pollution, and carbon emissions, had no ill effect at all. But enough is enough.

The evidence on warming is mixed, often exaggerated, but often reassuring. Global warming has been increasing constantly since 1975 at the rate of less than one fifth of a degree centigrade per decade. The concentration of carbon dioxide increased surface temperatures more in winter than in summer and especially in mid and high latitudes over land, while there was a global cooling of the stratosphere.

The East Anglia university climate research unit found that global temperatures did not increase between 1998 – 2005 and a recent NASA satellite found that the Southern Hemisphere has not warmed in the past 25 years. Is mild global warming a Northern phenomenon?

While we might have been alarmed by the sighting of an iceberg off Dunedin as large as an aircraft carrier we should be consoled by the news that the Antarctic is getting colder and the ice is growing there.

The science is more complicated than the propaganda!
