Maybe we should practise holding our breaths - will reduce the Carbon.
Climatologists interviewed on the radio and tv about the Day After Tomorrow scenario have all stated that global warming is a reality - what is NOT a reality is the significance of human contribution to the same.
The earth has warmed up and cooled down throughout its geological history and based on recent Pleistocene events, we should be heading for a gradual cooling sometime ni the future.
If they want something REAL to worry about - they should worry about polar reversals. Changes in the earth's core indicate a polar reversal is about to occur within the not too distant future. They are currently magnetic anomalies beneath the Pacific where magnetic north isn't where its supposed to be.
Or they could worry about rogue asteroids imploding into the earth's surface.
But I guess they can't blame this on the Capitalist life style, so its of no interest to them.
If I may humbly suggest... let those who are all worked up about it be the ones to hold their breath. Perhaps if they do it assiduously enough, it will set an example.
