5 ways to save the earth from GW.

[Ball Lightning]

Not your typical ways but i think the solar shield or cloud making is the best.

Five Ways To Save The World
Climate change is being felt the world over and if global warming continues to increase the effects could be catastrophic.

Could these men reduce the amount of sunshine hitting earth?

Some scientists and engineers are proposing radical, large-scale ideas that could save us from disaster.

The first three proposed ideas featured in the film, look at reducing the power of the sun - thereby cooling the planet.

Professor Roger Angel from Arizona - the designer of the world's largest telescope - is proposing to put a giant glass sunshade in space.

Professor Angel's sunshade will deflect a small percentage of the sun's rays back into space.

Dutch Professor Paul Crutzen won the Nobel Prize for chemistry when he discovered the causes of the hole in the ozone layer.

His plan is to fire hundreds of rockets loaded with tons of sulphur into the stratosphere creating a vast, but very thin sunscreen of sulphur around the earth.

British atmospheric physicist Professor John Latham and engineer Stephen Salter, have designed a fleet of remote-controlled yachts.

These will pump fine particles of sea water into the clouds, increasing the thickness of the clouds and reflecting the suns rays.

Carbon dioxide debate

The other two men in the programme want to tackle the problem of excess carbon dioxide - the cause of global warming.


Ian Jones (L) and Klaus Lackner ® are tackling carbon dioxide head-on

Sydney engineer Professor Ian Jones proposes to feed plankton with gallons of fertiliser.

This will make the plankton grow and absorb carbon dioxide from the air.

And New York-based Professor Klaus Lackner has designed a carbon dioxide capturing machine and his plan is to locate more of them across the globe.

They would suck in carbon dioxide, turn it into a powder and he would bury it deep under the ocean in disused oil or gas fields.

Most of the scientists are reluctant advocates of these ideas, and all believe we should be cutting down on our use of fossil fuels to heat our homes and drive our cars.

But is time running out for planet earth?

Although these ideas might have unknown side effects, some scientists believe we may soon have no choice but to put these radical and controversial plans into action.

Now I am scared.

Don't like the sulfur idea. Spreading sulfur around the globe... Sulfuric acid seems to come to mind.

Giant glass thing is too hard to work. Glass tends to warp and break after it reaches a certain size.

"suck in carbon dioxide" How do they do this sucking of carbon dioxide? The only thing I can think of is using it to make carbonic acid, and then turn it into calcium carbonate (limestone). (ok, chemical names may be wrong. But it's something like that.)

Like this: http://www.fossil.energy.gov/programs/powersystems/futuregen/

Edit: from what I have read from the article I would be like this:

You compress air, and the CO2 becomes solid (CO2 is solid at certain pressure and temperature) You take the solid CO2 and you put it inside a mine, or you pump it inside the Earth's crust, just like you pump oil out but the other way around.

I don't like the sulpher either.

The Solar shield is: Its put in the opbit of the sun, 1000000km from earth, theres going to be 1,000,000,000,000 2ft wide glass panels, with small solar sails to direct it. They will be spread out over 100000km^2.

There is but one man in politics that knows more, and can do more, about global warming than ANY other... Mr. Algore

but this is my favorite quote from the above article...

His plan is to fire hundreds of rockets loaded with tons of sulphur into the stratosphere creating a vast, but very thin sunscreen of sulphur around the earth.

this would be a spectacular event... i wouldnt miss the launchings for anything...

Just that you might live only for a few years to see it ...

Nuclear energy is better option.

I'm curious as to the effect of that much sulphur in the atmosphere.

The first three proposed ideas featured in the film, look at reducing the power of the sun - thereby cooling the planet.

That's really badly phrased. They should say something like "reducing the amount of the sun's energy that reaches the surface / atmosphere of Earth", not changing the actual sun.

"Lame. Don't these scientists ever think of anything original?"

lol why don't we just let the earth do its thing?

besides what makes people think this is the optimal world temp for humans?

Because the world will go spastic, like nearly all of NY covered by water by 2100.

And its not for 'humans' its for everything which lives here already.

Blah, We tell the earth what to do. And well I've grown to like this temp.

But humans are the very most important. And really, it is just for us. GW isn't going to kill all life on this planet, all it's really going to do is mess up life for us humans. And I know I'll pick a cow to die over a human any day of the week. mmmm steak......

All these men seem ot be playing with fire.

I like the Solar Shield Idea but only because it's in Alpha Centauri.

Although it does depend who starts the council vote, generally speaking Sister Miriam, Chairman Yang and Santiago always oppose the"launch solar shield" plan.

 

[Sophie 378]

Every time that proposal comes up, it's because the stupids have melted polar caps and drowned half their cities and now they want their land back. Or they've done so much ecodamage that there's sea level rise.

 

[scipian]

The solution will likely be worse than the disease.

BTW- I've heard that the North Pole is melting while the South Pole is freezing over. The fact that the North pole is melting doesn't matter because it is floating, i.e., the volume of water displaced will remain the same. Is this right?

 

[Narz]

These ideas are pathetic.

It's like "experts" claiming the best way to prevent spousal abuse is advising battered women to wear chain mail while with their abusive husbands.

Except for the Greenland ice.
