By John Nicol and Jennifer Marohasy, published 16/9/2016

At high altitudes, the greenhouse gases provide the only mechanism for the radiation of heat from the atmosphere to space.

Ant,
you can't possibly believe that US Military report. The algae made them write it! ;-)

In September, denier sites were suggesting that as the sea ice extent had risen quickly in September 2016, it meant that scientists were wrong about the Arctic being in a mess. The only statistics that matter are those when maximum and minimum values are obtained in April and September. But, data taken twice per year can be misleading. There can be huge variation from one day to the next. Sea ice extent increase has now decreased to be lowest recorded since 1980 for October measures (IJIS). Illustrative of the point being made, we do not have a crystal ball to determine what sea ice extent will be next week; or the following weeks through till April.

It just illustrates how denier sites do not fully comprehend what data means, and then jump to the wrong conclusion. The more sinister conclusion which could be drawn is that the author of the article published by WUWT fully comprehends how sea ice extent varies on a daily basis up and down.

As stated, the only significant stats come twice per year; though they can cause wrong conclusions to be made as there are variations in sea ice extent from year to year. It is the overall trend line showing data for decades that shows what's going on.

Ant posts some misinformation.
"The world’s ice caps will not care who is elected or what is said. They will simply continue to melt, as dictated by laws of physics."
The reality is that Antarcica has been growing in both area and mass since it was covered by rain forest.
NASA says
"A new NASA study says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.".
Further down NASA says
"According to the new analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001. That net gain slowed to 82 billion tons of ice per year between 2003 and 2008.".

For the Antarctic to have been gaining ice for such a long time without the seas falling means the planet must be gaining hydrogen and oxygen from some other place.
"Curiously, the decline in atmospheric oxygen over the past 800,000 years was not accompanied by any significant increase in the average amount of carbon dioxide in the atmosphere, though carbon dioxide concentrations do vary over individual ice age cycles."

The hydrogen is coming in every day as protons from space in cosmic radiation. Also as solar wind.
The only constant on earth is change.

With the Antarctic growing like that for so long we should have noticed global cooling from the ice albedo feedback unless either the planet is growing or something darkens the ice at incoming wavelenghths.
In steps alge.
"When an 1818 British expedition led by Captain John Ross tasked with finding the Northwest Passage stumbled onto "extensive patches" of this stuff near Greenland's Cape York in Baffin Bay, the Times of London confidently declared it to be iron-nickel meteorite detritus. In reality, the Scottish botanist Robert Brown -- he of Brownian motion fame -- suggested in an appendix to Ross's mission report that same year the color could be due to an alga, a photosynthetic microbe. And it was."

On the other hand the planet is growing.
