Climate intervention schemes could be undone by geopolitics : Comments

By Mike Hulme, published 21/6/2010

As global warming intensifies, demands for human manipulation of the climate system are likely to grow.

Climate engineering? We have already engineered our way into a perfect storm of climate disasters.I doubt if further engineering will improve matters.

Our resources would be better focused on reducing the pollution we are adding to the atmosphere and oceans.

We already have potentially catastrophic climate changes in progress resulting from several hundred years of pollution from the industrial age.I can't see harebrained schemes reversing this.

Manorina, unfortunately it seems likely that we have passed beyond the point where mitigation through reduction is likely, or even possible. The smart money is now on this sort of engineering, which I agree is pretty dumb!
Remember we live in an economy with accounting that treats both polluters' profits and cleaners' profits as equally virtuous. There is no "good profit bad profit". For this reason some big "solutions" (climate engineering and nuclear for example) are attractive to the same folks that are currently causing the problem!
The chance for cheap effective mitigation probably slipped by while Bush and Howard had us all in a lather about boat people and fantasy WMDs while the vampirish banking system mined western economies close to death.
Sure we could have re-arranged the economy and invested in sustainable energy...but instead we played a shell game and concentrated yet more wealth in fewer hands in the process. The US spent years of national income trying to secure one of the world's last remaining cheap oil sources in Iraq instead of using R&D to make good with what they had. The same sort of players now want to jump on the GW bandwagon by offering big, dangerous expensive "solutions" when things get bad enough to start costing.
As a start, I'd like to see just one sustainable Australian city.

Sure engineering solutions are of no use, for the very good reason that the earth may cool all by itself before anything can be done. As you all know we are in the middle of an el Nino, the onset of which led to hopeful pronouncements that this year be very warm like 1998 (also an el Nino year). Unfortunately for those forecasts, this el Nino is already proving to be milder than 1998 and there are indications in sea surface temperatures that we are already switching to an la Nina. Check out http://www.drroyspencer.com/ Spencer is a NASA scientist specialising in satellite measurements and a noted sceptic. Dump the ideology and get out your coats! The looming la Nina may be considered part of the general cooling, thanks to the Pacific Decadal Oscillation switching to a cool phase, but it is too early to state that definitely.
As scientists are now becoming to realise, the oceanic climate cycles are all-important is governing temperature. Human activity counts for little..

Why would anyone, not a doom sayer, ever read any article that starts with a completely unsupported statement such as, "As global warming intensifies"?

The time for this sort of B grade nononsense is long past. Yes it brings the dills, & fellow travelers out of the woodwork, but is of no interest to any thinking person, with any education to help them.

Surely we no longer bother with anything that comes out of East Anglia, after all we have learnt about the quality of their work.

According to climate commentator Anthony Watts' survey of 1221 USHCN weather stations, almost 90% of them do not comply with American standards by being located too close to buildings and other heat sources. What are we actually measuring?
According to solar expert David Archibald we are headed into a cooling phase. If the powers that be do not acknowledge that increased CO2 in the atmosphere is beneficial to all plant life and world food production and they are not willing to accept what the satellite temperature data is currently telling us, we certainly ought to be alarmed by the spin element of this article.
A species that couldn't even measure temperatures properly or recognise the benefits of the one of the earth's greatest resources brings about its own destruction through unnecessary geo-engineering.

Hasbeen, that was my immediate first reaction as well.

It could have made more sense if it was reorganised to read: "If (opening phrase) "is true, then...(rest of document)".
