Re: Is the science settled over global warming? If so when?

You pretend that the Antarctic Sea Ice has melted between last decade and this decade. In fact, that is farthest from the truth. In fact, in September, 2014, Antarctic Sea Ice set the ALL TIME RECORD in the satellite record at over 20 MILLION SQUARE KILOMETERS:WetEV wrote:Show me where the wind blew the ice. I don't see where it went.
Again, here is what happened last September, according to the National Sea Ice Data Center:The single-day maximum extent this year was reached on Sept. 20, according to NSIDC data, when the sea ice covered 7.78 million square miles (20.14 million square kilometers). This year's five-day average maximum was reached on Sept. 22, when sea ice covered 7.76 million square miles (20.11 million square kilometers), according to NSIDC.
What happens with sea ice is that it gets blown by the wind. When the wind blows strongly against the ice front, it compresses the ice into a smaller extent.NSIDC wrote:The early maximum appears to be the result of an intense wind pattern in September, spanning nearly half of the continent from the Wilkes Land area to the Weddell Sea, and centered on the Amundsen Sea. Stronger than average low pressure in this area, coupled with high pressure near the Falkland Islands, and near the southern tip of New Zealand in the Pacific Ocean, created two regions of persistent northwesterly winds. Sea ice extent decreased in the areas where the northwesterly winds reached the ice front.
They continued their narrative in their December, 2016, report:
Bolding mine.NSIDC wrote:When the westerly wind pattern broke down in November, winds in several areas of Antarctica started to blow from the north. Over a broad area near Wilkes Land, the ice edge was pushed toward the continent.
