<p>One possible action following your line of thought, would be to bring liquid water to the south pole from the coast and let it freeze there. However, the more than 500 km that separates the South pole to the nearest ocean shore (that is actually under hundreds of meters of ice) or 1,300 km to open water, makes this idea very impractical. A similar approach but more efficient would be to pump water from the coast to a nearby antarctic basin, and that would indeed help reducing sea level. This idea have been proposed by scientists.

<p>The North pole in contrast is just in the middle of the Arctic ocean. You could indeed take ocean water there and turn it into icebergs.

<p>Nevertheless, your feat of engineering would have a positive effect in slowing global warming by covering the ocean with a layer of highly reflective ice. That ice would reflect back to space a lot of sunlight that would have been absorbed by the ocean otherwise. However, when you freeze sea water, most of the salt is expelled, so you would also put a lot of salt into the water, that would make sea water more dense and it would sink. That could have a undesired effect on ocean circulation, so you have to be very careful in studying the side effects of such approach.</p>

<p>Similar to the antarctic approach. You might get better results if you pump water from the Arctic ocean and let it freeze on top of a desolate arctic island. However, it still doesn't seem to be the most cost effective approach.</p>

<p>Said that, there is a long list of geoengineering ideas to battle against climate change and sea level rise. However, the most cost-effective way to slowdown sea level rise, is to reduce the rate at which we are consuming stuff. So just buy less and reduce/repair more.

Having less children or adopting instead of having your own is also a way to make big contributions to slow down sea level rise.</p>

<p>Is it possible that human can built under the poles a controlled system to create again artificial icebergs? In order keep tight the melting ice and reduce the sea level? Can this system impact the quality of life and climate?</p>

What do you mean by "under the poles"? The North pole has about 3 meters of ice, and water under that where I guess you could go "under".  The South Pole has rock under the ice.  How would you go about creating "icebergs" under the northern ice cap? Ice is formed at the surface for a reason.  Latent heat is released during the process, and it would need to release the salt somehow.  It's good to think of different ideas to keep quality of life, but this one would need a whole lot of other engineering problems solved before it could be even considered.

Any sort of artificial refrigeration system would create more heat.  Refrigerators just move heat around: that's why they have fans and cooling fins.  (Usually on the back, or underneath.)

one good thing with your question is you understand the need for action against the heating of our planet,the easiest way to do this is to stop burning oil and coal.

Only by releasing a lot of heat into the environment, which just makes the problem worse.

Creating ice in the ocean won't reduce sea level.  You need to create ice on land to reduce sea level and the volume required to have an effect would be gigantic.    There are, however, some proposals to keep land ice (usually called glaciers) from melting.  I've never heard of a proposal to create more ice and it's probably not feasible.
