5 ways to save the earth from GW.

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?

"The South Pole is freezing over" is actually badly worded. The southpole is warming up too, but not enough to melt its onshore ice. And as a warmer atmosphere holds more water, increased snowfalls on the South Pole are expected.
The second phrase is right if you just consider sea levels. But a problem linked to the northpole melting is that it will then reflect less sunlight, and will thus provide a positve feedback mechanism for further warming.

"Save the world from GW." Save it from George W?

Well, we cold just cut down on fossil fuel consumption, an dplant more forrests...but no, I think that putting a giant glass sunshade in space sounds simpler.....oy...!

What about Highlander 2 way with a vomit red shield replacing the skies?

Lightning,

Try clicking on your link,

then click Ctrl and f at the same time and search for "Bush" and "America". Not the complete lack of use of either when identifying any problem.

Reducing the amount of sunlight that reaches the Earth would be disastrous for our ecosystem. Plants simply wouldn't get enough light...

I bought a white car, so that the space it's parked is reflecting light back away from earth.

If we reduced sunlight indensity that low, I'm quite sure we have more problems than simply the lack of growth of plants.

Not only that but you double the amount of momentum imparted on the Earth by the incoming photons, since this only occurs during the day it adds an additional thrust to the Earth in an outward direction increasing its distance to the sun and thus lowering the amount of solar radiation in the first place!

The solution will likely be worse than the disease.

No as ice takes up less room then water so that when it mealts it expands, like when you put ice into a glass of water if you let it mealt it'll go over the edge.

And that to.

I do the same, all we have to do to save the planet is paint everything on the planet white.

Ahh, no...

Something that floats displaces it's own weight, so if it melts it still displaces its own weight, only in a smaller total volume but same volume in liquid. Spilling over in a glass probably has something to do with water's amazing surface tension.

On topic, I think dumping more stuff into the atmosphere to fix the stuff we dumped in earlier is a bad idea. We're better off letting the earth take care of it, something it's proved to be very good at over the eons.

 

[Lotus49]

Bah. Let's just screw with the Earth even more, and see what happens. I mean, how bad could it be? Surely we've completely thought this through - every angle - and nothing unforseen could occur afterwards.

 

[ParkCungHee]

Or because you know, the Ice isn't entirely underwater. Theres still that continent sized patch of Ice floating on the surface, and the parts of the Ice Caps that have land beneath them.

That's not correct. Water is one of a (apparently few) substances that expands when it freezes; ice is less dense than water, hence it floats. Completely fill a water bottle and throw it in the freezer, upon freezing the bottle will bulge out of shape or burst outright.

Gallium and bismuth are supposed to expand upon becoming solids as well.

 

[Chunes]

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.

Actually that would depend on the source of climate change.. It's the sun, so chainmail is the real solution.

True, but ice does not float purely on the surface of water. It floats partly above and partly below.

Any volunteers to work out the respective volumes of a fixed volume of water, ice, and water displaced by floating ice?

 

[El_Machinae]

Floating objects displace their mass in water. The volume of water doesn't change whether the ice is melted or frozen, as long as it's floating free in the water.

The mass of ice over Greenland is one of the potential problems, though. Melting there will flow into the sea.
