"Antarctic precipitation, is this compensating for melting ice elsewhere?"

No.

180 degrees az-backwards.

A massive scientific study recently written up in Science magazine

http://www.sciencemag.org/content/340/61...

indicates fairly conclusively (though there are still some uncertain elements) that the world's ice, overall (including the Antarctic), is melting much faster than can be explained by any sort of possible natural cycles.

If you "read that due to extreme snow precipitation in Antarctica, global sea level rise is being mitigated, if not halted" you have probably landed on a fossil fuel anti-science myth-recycling site, or some place copy-pasting from such a denialist source.

At Yahoo Answers there is no penalty for giving deliberately false answers. Indeed half the "top ten" contributors in the category "global warming" are hard-core anti-science serial liars.

In sharp contrast, top scientists have had consistent conclusions for over twenty years that the unusually rapid global climate change of the past century has been mostly human-caused. Fossil Fuel companies have often denied this science and Republican politicians in the U.S. have been adamant lately in espousing such anti-science denial. A range of anti-science con artists, pretending to be the "other side" of a scientific "debate" on whether anthropogenic climate change is a serious long term issue, are prevalent on-line. Yahoo Answers is loaded with deniers-in-training trying to copy-paste such deception. It is advisable to do your own homework on this subject. Here are some links:

RE the real science:

U.S. National Academy of Sciences, 2010:

“Climate change is occurring, is caused largely by human activities, and poses significant risks for a broad range of human and natural systems.”

http://www8.nationalacademies.org/onpine...

“Choices made now about carbon dioxide emissions reductions will affect climate change impacts experienced not just over the next few decades but also in coming centuries and millennia…Because CO2 in the atmosphere is long lived, it can effectively lock the Earth and future generations into a range of impacts, some of which could become very severe.”

“The Academy membership is composed of approximately 2,100 members and 380 foreign associates, of whom nearly 200 have won Nobel Prizes. Members and foreign associates of the Academy are elected in recognition of their distinguished and continuing achievements in original research; election to the Academy is considered one of the highest honors that can be accorded a scientist or engineer.”
