There’s not much future in predictions : Comments

By Tom Quirk, published 1/12/2006

The Stern report is all very well but we simply can't forecast the impact on our climate in 100 years with any accuracy.

Having just seen An Inconvenient Truth, am inclined to believe Al Gore. He has too much to lose to peddle lies. Found it credible and convincing. Anyway predicting 100 years ahead is at least a platform to work from. Does the author have a better prediction? With action much may be preventible.

Tom,

Do you think you have the bigger picture that just future climate change...meaning is climate change the fundamental issue or is it part of the issue making the fundamental, in which case what is the fundamental... I think its a earth that we can walk, talk and laugh in with our god given body, not living in an artificial city with controlled environment as the earth has become too toxic for most lives. Yep...some corporation will control the life sustaining facilities and we have to essentially be slaves to the system to survive...

Sounds like science fiction, maybe, but here are a few facts. See WWF site, it states that we have lost more than half the plant and animal biomass in the last 30 years. This figure is closer to 96% when its compared to time when industrial revolution started.

Something else, fat tissue of all animals and fish show toxic chemicals in abnormal levels. Fat is a good disolver and reduces the concentration of these toxic chemicals in our blood but if we continue to ingest food with these chemicals...well all safety systems have limits.

Other facts, all put together shows that earth has been 'dying' and we human survive because we have technology to enable us to...transport food from where it can be grown to where it cannot etc

So the ultimate question is this, have we doomed our future or are we on the edge of it and we have to do major changes now...I think the later, at least as long as we have enough plants to produce life giving oxygen, of which there is no other source...

Presumably Mr Quirk doesn't insure his car or have superannuation either, because the future is so uncertain, you know, and i read one report once that said it doesn't pay.

The 100 yr prediction of an economist i wouldn't change my socks over, but the measureable loss of arctic ice, megadroughts, hurricane incidence and many other CURRENT changes are.

How typical of RightThink to focus on one tiny part of the story, misrepresent it, and keep plugging economic fundamentalism as the unchallengeable Good that all else must give way to. Can't do anything about climate change - might hurt the economy!! Surely the dumbest line to come from Howard in a long time, and thats saying something.

Incidentally, i might know why RightThink articles are so short, and getting shorter - the more 'thought' and 'evidence' (i use these terms very approximately) they put in, the more the rest of us can examine their evidence and see how bare arsed naked their emporer is. Same reason Bush & Howard never do unscripted interviews, they know they're 'full of it'.

Tom, a breath of fresh, cooling air in the overheated accelerated global warming debate. The Australian recently printed the following letter from me, which I commend to OLO readers:

"UK Environment Minister David Miliband claims that the scientific evidence on climate change is overwhelming ("Denial won't halt global warming," 14/11). But the IPCC's warming estimates for 2100 are based not on science but on economic modelling, with highly contentious assumptions about the relationship between economic growth and increase in greenhouse gases.

The world is so variable that medium-term economic forecasts looking 3-5 years ahead have limited accuracy. Yet the IPCC depends on 100-year forecasts. Even worse, these forecasts have been demonstrated by experts such as former Australian Statistician Ian Castles to have serious flaws which exaggerate growth and emissions. Some of the modelling results are incredible - for example, showing that South Africa's national income in 2100 will exceed world income in 2000. However, the IPCC has flatly refused to revisit its modelling.

We don’t know what the course of global warming will be in the next 100 years. We do know that climate is, and always has been, highly variable, and can pursue policies which increase our capacity to respond positively to changing climate and economic circumstances rather than policies based on a view of what may or may not be the situation in the 22nd century."

The world may or may not be warming at an increasing rate; this may or may not be due to human activity; I don't think that either has been fully determined. What has been clearly demonstrated is that the IPCC's scenarios and resulting temperature rise projections are very seriously flawed. The "precautionary principle" raised in response to Richard Castles suggests that we shouldn't put all our eggs in the very badly-woven IPCC basket.

Mr Quirks article reminds me of George Dubya Bush going into Iraq - those of us who went to Vietnam, or lived through taht time could see another impossible Vietnam looming from miles and months away, but oh, who knows? - we can't judge this situation by the last, can we, now? Or, can we?

Rectal Myopia I call it - heads so far up their backsides ( or too many hands putting money in THEIR pockets.

You couold use the same argument in favour of cigarette smoking - hey, I know heaps of people who lived well into their 80's and 90's who smoked until they died etc. We cannot predict with any certainty who will die from smoking and who will not, can we?

But, we all know the statistics are not good - same with factories and power stations and vehicles pushing out millions of tons of pollutants DAILY - plenty are sick already but who knows what the long-term effects are?

WE CAANOT AFFORD to wait and see, as Mr Quirk advocates - we HAVE to do something NOW - for our kids and their kids and so on!

Very Scientific Mr Quirk, but lacking ONE ESSENTIAL INGREDIENT - Common Bleeding Sense !
