The left wing wants to push ahead with mitigation policies for climate change, it is their unerring belief that the state and governments can control the climate through control and taxes.
The other side says that the climate will always change and we should look at adaptation rather than expend vast quantities of cash on ultimately futile efforts.
Las Vegas couldn’t exist without air conditioning, neither could Dubai or other cities in the middle east. Human beings are great at adaptation, it is why we are top of the food chain.
Still there is no evidence yet presented that the predicted climate changes have actually happened, or if they are happening at the rates the alarmist have stated. In fact he opposite is true.
So what is it to be? Mitigation and huge costs, or adaptation?
The latest report from the UNās Intergovernmental Panel on Climate Change (IPCC) is due out next week. If the leaked draft is reflected in the published report, it will constitute the formal moving on of the debate from the past, futile focus upon “mitigation” to a new debate about resilience and adaptation.
The new report will apparently tell us that the global GDP costs of an expected global average temperature increase of 2.5 degrees Celsius over the 21st century will be between 0.2 and 2 per cent. To place that in context, the well-known Stern Review of 2006 estimated the costs as 5-20 per cent of GDP. Stern estimates the costs of his recommended policies for mitigating climate change at 2 per cent of GDP ā and his estimates are widely regarded as relatively optimistic (others estimate mitigation costs as high as 10 per cent of global GDP). Achieving material mitigation, at a cost of 2 per cent and more of global GDP, would require international co-ordination that we have known since the failure of the Copenhagen conference on climate change simply was not going to happen. Even if it did happen, and were conducted optimally, it would mitigate only a fraction of the total rise, and might create its own risks.
And to add to all this, now we are told that the cost might be as low as 0.2 per cent of GDP. At a 2.4 per cent annual GDP growth rate, the global economy increases 0.2 per cent every month.
Those are massive costs…I doubt the world could sustain them, let alone have them work at all.Ā Read more »
