Skip to comments.Going to extremes to fight global warming (55,000 Mirrors will save the globe?)
Posted on 06/03/2006 7:12:46 PM PDT by DaveLoneRanger
It may be hard to imagine the world getting so hot that scientists and engineers would design a fleet of 55,000 mirrors, each bigger than Manhattan, and send them into space to deflect sunlight away from Earth.
Or that they would mimic a major volcanic eruption in order to cool the melting Arctic, shooting dust and other particles into the upper atmosphere where they would scatter the sun's light away from Earth.
Using geoengineering, the large-scale manipulation of the environment, to combat global warming has been proposed by scientists like Lowell Wood at Lawrence Livermore National Laboratory in California.
He argues that simulating a volcanic winter -- the cooling that follows major volcanic eruptions like Mount Pinatubo in 1991 -- is the most practical approach to managing global warming.

Mimicking a volcano by shooting particles that scatter light into the upper atmosphere could damage the ozone layer.
Well DUH. They harp at us for years about driving SUVs, and then we come back at them by saying volcanos pollute more than our SUVs do, and then they say "well, let's use a volcano to cool the globe!"
Then we're reminded of stories like this:
Blocking sunshine with aerosol may help avoid global warming
Burning Fossil Fuels Has A Measurable Cooling Effect On The Climate
Using mirrors in space would cause the sun's light to flicker.
See: To Cool the Earth, Plan Would Pull a Shade (Glass shield in space will save earth) for an alternate yet similarly brilliant plan!
Overall, this sounds like a dangerous idea, even if it will never go anywhere. Tinkering with earth's climate to fix a problem no one is certain we are responsible for, and some aren't even sure exists is too extreme.
I guess they aren't expecting such as increased volcanic dust on top of increased meteor hits of significant sizes . . . .and probably increased wind storms . . .
But some of us are.
I'm in favor of launching large, city sized solar power generators into space and using them to help regulate the output of solar energy that reaches the planet.
Aside from the power generated that can be beamed to various orbital and possibly lunar facilities, it is probably a good idea to plan for sudden changes in the suns output. Also, building these mirrors/solar arrays would cost a great deal of money, require an increase in the space budget, and probably require lunar or asteroid mining, and an orbital manufacturing plant to complete the project.
The only problem is that one can't trust any government to actually complete such a project. So the issue is moot.
I can get along just fine with their warming BS, they should start thinking about how to warm it up when the new ice age arrives (as soon as no one will listing to global warming), it might be a lot harder than trying to cool it down.
I'm in favor of launching large cities into space. Anything with more than a million within the city limits.
Hey! It's a start! It sounds like somebody has figured out that the sun might have something to do with "global warming."
So when it gets too cold, they turn the mirror around and warm thing up again, right?
It is all a sinister plot.
They SAY that they are going to build it to 'save the world'... but what they are really going to do is build a giant space umbrella and cut off all the direct sunlight over America unless we pay them ONE JILLION DOLLARS.
They got that idea from watching the Simpsons, after that shark with laser beams thing didn't work out for them.
Fry: This snow is beautiful. I'm glad global warming never happened.
Leela: Actually, it did. But thank God nuclear winter canceled it out.
The solar shade sounds like it would be more feasible than the volcano. Using the proper materials to manufacture it, you could turn it off if you wanted.
I'm not sure of the total population, but can we launch San Francisco first? If that works, then NYC second?
Why not have low orbit venetian blinds.
Fair enough. We city slickers are already happily ignoring the rural areas of the country, so it probably wouldn't make too much of a difference to us either way.
Do we let the liberal urban areas take air with them?
