In 1988 Atmospheric Physicist Dr. James Hansen, now head of the NASA Goddard Institute for Space Studies, testified at a US Senate Committee hearing that:
it was 99 percent certain that the warming trend was not a natural variation but was caused by a buildup of carbon dioxide and other artificial gases in the atmosphere
Why would the President or anyone in his Cabinet re-write someone's testimony? Why use deception and pressure to get a scientist to say what he knows isn't true? It's a very different kind of thing than engaging the scientific process and hearing what other scientists have to say on the subject.
I think many of them,and noteably David Keith are "double minded" men....they have convinced themselves that they can pollute the planet with Sulfate Aerosols
to "correct" AGW...one minute, and the next they say it would be the last ditch
effort because it would also ruin the earths atmosphere!

No. They don't say it would ruin the atmosphere. They say that the possibility of unforeseen consequences is too great to think about using aerosol SRM unless the warming reaches catastrophic levels. They are in favor of reducing pollution (including greenhouse gasses) in order to avoid that. They are also in favor of continuing the use of computer and laboratory modelling to study the ramifications of the use of aerosol SRM.

Wigington: “Did you do a study on human respiration? 10 megatons of aluminum dumped into the atmosphere will have no human health impacts?” Keith: “Let me be more careful here… to separate out the toxicological crux. The aluminum we have only begun to research and published nothing. Mostly worked on sulfur and the relevant comparison is that just as Robock said...(referring to sulfur particle number studies mentioned by Alan Robock). “The whole thing he just got through was particle numbers, the impact of particle numbers…but we haven’t done anything on aluminum. So if we add onto the tropo aerosols, could we have any impact? That was totally irrelevant. That was just on particle numbers... But we haven’t done anything serious on aluminum and so there could be something terrible that we will find tomorrow that we haven’t looked at.”
Please name another civilization on earth that did it and needed it.
Yeah. It's called polllution. Cars and factories and stuff.
On top of that, There are many air samples that have been taking that show increased heavy metals.
And he didn't say "We aren't using 10 megatons" he said "We are just now testing it on human health, But we haven't released anything"

Tell me again where he said they are just now testing it?edit on 3/28/2013 by Phage because: (no reason given)
600 million years ago when the tropics froze over.

Really? Aerosol SRM when the first animals showed up? The tropics were frozen?

Where did he say they are just now testing it?
You're right.
Yes the tropics froze, Unless you have an explanation for how the glacier formation happened there.
I don't think it's the first time. But it is the first time in recorded history.
If you think what we are going through now is the first than you're wrong.
More than 600 million years ago? That would seem to be one of the requirements.
Do we have more radiation coming off the Sun now than then?
Everything does not seem to be ok. Things seem to be getting warmer. If they continue to get warmer it will not be good for a lot of people.
Or are we supposed to just say everything is okay, They are just blocking out the Sun. No need for Sun Screen.

Low CO2 levels, reduced solar irradiance, and changes in ocean currents all at the same time can account for it.

Who is blocking out the Sun?

Yes. I heard that. I didn't hear the part about testing though.
