Mimicking Volcanoes May Cause Drought

The idea of pumping sulphur particles into the atmosphere as a last-ditch solution to global warming might have hit a snag, according to a pair of scientists from the National Center for Atmospheric Research in Colorado.

This process is supposed to reproduce the cooling effect of a large eruption by sending sulphate particles into the stratosphere. The particles, otherwise known as "sulphur sunshade" reflect some of the sun's radiation back into space, which in turn reduces the amount of heat that reaches the planet, according to the article in NewScientist.

In the study, Kevin Trenberth and Aiguo Dai show that "sulphur sunshade" would have catastrophic effects on the planet's water cycle and lead to widespread drought. They cite the post-eruption of Mount Pinatubo from 1991 as one example where rainfall and run-off was significantly reduced.

It doesn't surprise me that man can screw things up.
The trick is still that we have a very limited understanding of how things work. We pretend that science that has a full grasp of things, but that isn't true and our hubris in claiming that we do leads to idiocy, like destroying scientific debate through name-calling and religious-like zealotry advocating one theory.
I think of the occasional blizzard as a healthy reminder that man does not rule the planet as he thinks.
The conceit that we know more than we do and can control weather (we can influence it beyond a doubt) when we can't goes right along with GW's presumption that somehow there is an optimal status quo for climate.
There isn't, and if you create one it will inevitably screw over some region and help another.

Patrick Henry:

We spent decades working to remove particulates from the atmosphere here in the US, and now AGW zealots are seriously considering putting them back.

It would be nice if the AGW crowd could step back from the brink and try to look at the world objectively. For scientists, AGW is a cash cow. For politicians it is an easy way to get votes. For journalists it sells print. But for AGW groupies it is just a way to avoid having to think about anything real.

Andrew:

Nothing wrong with thinking outside of the box for potential solutions. However, it does not take much judgement to realize that purposefully adding anything to the atmosphere will have negative side effects.

Far better to reduce the amount of emissions.
I realize that nobody wants a carbon dioxide tax or a methane tax. However, if income and sales taxes were reduced (or at least did not rise) then the effect on the AVERAGE taxpayer would be minimal.

This would be a much better solution. If anybody really wants to drive an oversized Hummer, then they should pay big time for Global Warming.

People that walk, ride bikes or other activities that do not pollute should get a tax break.

WeatherWatcher:

I saw this a while ago and thought it scary. Glad to know reservations are being expressed.

Mary:

Another reason man should not muck with trying to "solve" AGW when he really knows so little about climate. And there is always the law of unintended consequences that can cause more harm than the perceived benefit.

The following link shows how trying to promote biofuels to "save" the earth will probably do even more damage to the earth and may cause more undesireable climate change. This is why when politicians say, just raise the the taxes on gas and everything else related to consumption, and make the common man use more biofuels, etc., it may not always be such a good idea.

Andrew,

Don't want to burst your bubble but CO2 is not causing GW. I won't ask you to produce any proof as you have been incapable of doing this so far. I say let's create a tax on idiot ideas.

If you support AGW then you pay extra for all of your goods and services and y'all can spend those taxes on whatever you please. I want no part of it.

Here's a little tidbit about climate. http://www.washingtontimes.com/article/20070814/NATION02/108140063

I rather liked hearing that some European officials are attempting to distance themselves from the AGW lunacy. It is refreshing to know that some of our cousins across the pond are using these big beautiful brains of ours for things other than figuring out how to screw those of us who are capable of living our lives without the need to be told what to do or how to do it.

Marcus Aurelius: "The object of life is not to be on the side of the majority, but to escape finding oneself in the ranks of the insane."

AGW'ers: "Consensus is the object of life, where I like you if you're like me."

Regards,

Steve

Patrick Henry:

NGW Steve,

Now that UK officials have had to invoke terrorism laws to hold back the AGW monster they fed for the last few years, perhaps they are starting to pull their collective heads back into the sunshine?

Jeff:

Andrew said: "People that walk, ride bikes or other activities that do not pollute should get a tax break."

I am honestly beginning to wonder how old you really are. What about the CO2 that they emit by breathing? What about the CO2 that is given off by making these bikes and shoes they use up?

EVERYTHING POLLUTES! You are either naive, blind or very young to follow the Goreacle so blindly.
