Solar geoengineering is a criminally insane idea. On one hand, these "scientists" are worried about pollution caused by natural atmospheric gases yet they are proposing to sprinkle the atmosphere with a totally foreign substance!
Pure evil and stupidity and a huge dose of hubris!

I hate to be the one to tell you but, they are already doing this. They will try to tell you that they are only contrails from jet planes but, if you look at normal contrails they don't appear to be anything like the ones from these planes. I have seen clear deep blue skies in the morning and once these planes start spraying out this garbage the whole sky become a muted white blue after they spread out. It is sad that the some scientist think once they gain a small amount of knowledge about how our planet works that they now believe they know everything. Nature does a pretty good job of things on its own without these people interfering.

Please, don't mess with the sky and our atmosphere. It is damaged enough.

A huge dose of hubris indeed. But is it any larger that refusing to acknowledge human caused climate change and continue to do essentially nothing about it? We are quickly being forced into doing something insane by not doing the sane thing now. Tax carbon now or pay later.

This is insane. Messing with the atmosphere. Scientist are idiotic to try something like this. They have no way of predicting the outcome. Just like when the ecologist tried to save the cork trees. Told the winemakers to use plastic. The demand for cork went down. No demand, the cork tree growers cut down the cork trees for other more profitable crops. Same thing will happen here, there is just know way to predict the outcome of trying something that may well turn slow global warming and natural climate change into a quick extinction level event. If they screw up, how are they going to get the aerosols out of the atmosphere?????

I was surpised to see no mention of chem-trails in this article. This geoengineering is already in action. Surely we have all witnessed the skies criss-crossed with jet trails which persist for hours and spread out all across what was formerly a clear blue sky. Check it out! There are numerous photos and info on the web. It appears that the trails contain Barium and Aluminum particles.

...an utterly depressing and distressing piece....almost beyond imagination...
"...Caldeira hopes the team’s work will help discourage any move towards implementing solar engineering...."
...I could not agree more...too painful to think about...I want to forget this now...

The problem is temperature imbalance Global warming means the surface of the Ocean is heated (stratification). The Earth has plenty of cold water to regulate the atmosphere. Sea water is over 680 times denser than air if you cool off the surface of the Ocean the air would cool off over night. We patented a system to deal with Climate Change. http://www.google.com/patents/US8083438

This is ridiculous. STOP POLLUTING THE ATMOSPHERE! You damn pseudo scientists. All you do is kill the planet. Why do we "need" whiter skies? They should be blue you stupid idiots with the clouds on it, not the whole sky as a single cloud. You go build your own planet and perform stupid experiments. Already enough.

Is that what you call your chemtrails? Solar Geoengineering? Leave the sky alone and it will be fine. Why don't you work on having a whiter, brighter conscience?
