Answer by user40405 for Dropping ice in the ocean to stop global warming
It depends on the ice composition, amount, and where you release itCurrent theory is that the previous ice ages were caused by large amounts of glacial ice being dumped into the Mid Atlantic Current,...

No, or at least with ice (snow)After read the SJuan76 and kingledion you can notice that it's almost impossible get colder the planet using comets. A comet has very low water compared to the entire...

To put things in perspective, the volume ratio of water ice on Earth to ocean is approximately 1/43,750,000. If all the ice on Earth melted (which it may yet do), it is the same as placing 1 gallon of...

Build a really big orbital beanstalk.Catch ice. Raise (warmish) water and lower near-0-K ice, trading their KE with minimal friction.Build large glaciers from this ice, increasing albedo of Earth.This...

Entropy will mess that all up. While the ice could lower the temp. barely, eventually the ice will melt, causing higher sea levels. Plus, think of it as percentages. In school if you get something...

Sort of, but not for the reason you thinkOne of the biggest problems with global warming is that it has an accelerating effect due to the melting of the ice caps. Since light colors reflect light while...

It won't solve the global warming, Because , to make those ice cubes , you have to cool water , to do that you have to reduce the thermal energy of the water and that thermal energy will add to the...

Yes, black holes can be coolTo begin with, we will have to add a mere $2.8\times10^{16}$ kg of ice per year. Based on SJuan's estimate of $1.35\times 10^{21}$ kg for the mass of the ocean, this is just...

To get rid of heat, you need to move the heat energy from the hot area to a cold sink. The heat energy the Earth is receiving is eventually radiated away to the cold and darkness of interstellar space,...

Yes. It's like dumping floating mirrors into the ocean.The white of ice cubes reflects light (read: heat energy)Part of the reflected heat energy would otherwise be absorbed by the dark blue seaIce...

If we drop enough ice to rise ocean level sufficiently (say 60 feet = 20 m), lots of prime ocean-front land will get flooded. Factories, cities, farms, nuclear power plants. Raised oceans will also...

@SJuan76 's answer is incomplete. He did the math to show the small cooling effect of, but didn't show the heating effect. I shamelessly copied his cooling numbers, and added heating numbers to...
