Is the artic melting Is Cause by Global Warming?

A more believable way of thinking is maybe the Earth is returning to its normal climate.

Yes the Arctic is melting through global warming, although many disagree on the cause of global warming, and many point out that for the last ten years there has been little or no warming maybe even some cooling.

Arctic ice melt has many causes, it can be heat from the suns radiation, from a warm atmosphere, warm ocean currents, or Arctic storms breaking up the ice and pushing the pieces south to warmer water.

The paradoxical phenomenon is thought to be caused by relatively cold plumes of fresh water derived from melting beneath the Antarctic ice shelves.

This melt water has a relatively low density, so it accumulates in the top layer of the ocean.

The cool surface waters then re-freeze more easily during Autumn and Winter.

This explains the observed peak in sea ice during these seasons, a team from the Royal Netherlands Meteorological Institute (KNMI) in De Bilt says in its peer-reviewed paper.

Climate scientists have been intrigued by observations that Antarctic sea ice shows a small but statistically significant expansion of about 1.9% per decade since 1985, while sea ice in the Arctic has been shrinking over past decades.

The researchers from the KNMI suggest the "negative feedback" effect outlined in their study is expected to continue into the future.

They tried to reproduce the observed changes in a computer-based climate model.

The sea ice expanded during Southern Hemisphere autumn and winter in response to the development of a fresh, cool surface water layer, which floated on the denser, warmer salty sea water below.

This fresh water is ultimately derived from enhanced melting at the base of the Antarctic ice shelves.

"Sea ice around Antarctica is increasing despite the warming global climate," said the study's lead author Richard Bintanja, from the KNMI.

"This is caused by melting of the ice sheets from below," he told the Reuters news agency.

But there are other plausible explanations for Antarctic sea-ice expansion.

Paul Holland of the British Antarctic Survey (BAS) stuck to his findings last year that a shift in winds linked to climate change was blowing ice away from the coast, allowing exposed water in some areas to freeze and make yet more ice.

Yes. Global warming has melted alotta ice

Global warming is cause by many things, effecting many things. Ozone depletion can indeed be. A big part of it causing what is called the green house effect, like that of Venus. It's caused by pollution, contamination. But yes it can be the cause of the arctic melting.

False cause hypothesis. Correlation is not causation.

yes
