DESPITE growing interest in clean energy technology, it looks as if we are not going to reduce emissions of carbon dioxide anytime soon. The amount in the atmosphere today exceeds the most pessimistic forecasts made just a few years ago, and it is increasing faster than anybody had foreseen.
Even if we could stop adding to greenhouse gases tomorrow, the earth would continue warming for decades and remain hot for centuries. We would still face the threat of water from melting glaciers lapping at our doorsteps.
What can be done? One idea is to counteract warming by tossing small particles into the stratosphere (above where jets fly). This strategy may sound far-fetched, but it has the potential to cool the earth within months.
Mount Pinatubo, a volcano in the Philippines that erupted in 1991, showed how it works. The eruption resulted in sulfate particles in the stratosphere that reflected the suns rays back to space, and as a consequence the earth briefly cooled.
If we could pour a five-gallon buckets worth of sulfate particles per second into the stratosphere, it might be enough to keep the earth from warming for 50 years. Tossing twice as much up there could protect us into the next century.
A 1992 report from the National Academy of Sciences suggests that naval artillery, rockets and aircraft exhaust could all be used to send the particles up. The least expensive option might be to use a fire hose suspended from a series of balloons. Scientists have yet to analyze the engineering involved, but the hurdles appear surmountable.
Seeding the stratosphere might not work perfectly. But it would be cheap and easy enough and is worth investigating.
This is not to say that we should give up trying to reduce greenhouse gas emissions. Ninety-nine percent of...

Always remember - the goal is global communism with elite leftists in charge of all production and distribution.
“Global Warming” is but one way that they are attempting to reach this goal.
I have a better idea -
those who believe CO2 is a pollutant should stop breathing.
Problem solved.
You put a CFL bulb in your refrigerator and you’ll have to leave the door open if you waant it to light up; they won’t work cold.
I was thinkink if we could get Hil-Rod, Howard Dean and Nuancy Pelosi to shut their yaps, it would go a long way toward the cooling.
“Here, I’ll put on my own mad scientist hat, here’s my cure to global warming:
A Cure To Global Warming
Place all the nuclear weapons on the planet at a central location near the equator. I’ll let the politicians squabble on the specific location. When the Earth’s rotation is such that the weapons are in direct alignment with the sun, detonate them. The tremendous force will push Earth out of it’s current orbit, resulting in a new orbit further from the sun. Hopefully the location isn’t too far away. If it’s a bit too far away we can always toss out the Kyoto protocol and rewarm the atmosphere enough the good old-fashioned way.”
I’ve got an even better idea.....Let’s just shut all the liberals up. Not only does it end the global warming, but it will give us peace and quiet since we wouldn’t hear their screeching.
The effort required to print all this BS about climate change controlled by humans is causing global warming.
God will warm or cool the earth as He sees fit. He is in control, not us.
Caldeira definitely knows what he's talking about, and he probably is serious. He's got an impressive publication list and breadth of interests.
I don't completely agree, but I do agree a lot can be done technologically.
The atmospheric lifetime of sulphate aerosols is pretty short. The Pinatubo cooling effect persisted for about 3 years, diminishing with time. If sulphate aerosol production was implemented and it was seen as necessary to shut it down, the effects would rapidly disappear as sulphate aerosol concentrations declined.
Sulphate in the stratosphere won't appreciably influence the pH of preciptation.
Which would make entire continents look like Copperhill, TN did in the 1960's.
Please examine point #4 in my profile.
Please examine point #5 in my profile.
That does seem like it would work, though...
Actually, the Holocene is a long and remarkably stable interglacial already. Milankovitch cycle solar forcing impacts are expected to be low so it is projected to continue for several thousand years more.
