On December 12, 2007 the BBC announced the Arctic would be ice-free by 2013. Since then there has been no trend in Arctic sea ice extent.
“Our projection of 2013 for the removal of ice in summer is not accounting for the last two minima, in 2005 and 2007,” the researcher from the Naval Postgraduate School, Monterey, California, explained to the BBC.
“So given that fact, you can argue that may be our projection of 2013 is already too conservative.”
“In the end, it will just melt away quite suddenly”

Antarctic sea ice is growing very quickly and extent is a little below the 1981-2010 average. Google AI says it is hardly growing and the lowest in 7.5 million years.
RIDDLE OF THE GLACIERS.
Ice Retreating.
GEOLOGISTS STILL PUZZLED.
CANBERRA, Thursday.
One of the riddles which is puzzling geologists all over the world is the continuous retreat of the ice glaciers. Does this phenomenon indicate that the sun is getting hotter as some astronomers believe or is it dependent upon comparatively unimportant changes in the earth’s atmosphere ?
Consideration such as these were discussed by Professor R. Speight, formerly professor of geology at Canterbury College, Christchurch, New Zealand, and now curator of the Canter-
bury Museum. In his presidential address to the geology section of the Science Congress to-day. His subject was “Some Aspects of Glaciation in New Zealand.”
The steady retreat of the glaciers in New Zealand he said had been observed during the last 70 years. Photographs taken in 1896 and 1935 showed that several glaciers had retreated distances varying from 100 yards to half a mile in 40 years.
WORLD-WIDE PHENOMENON
The phenomenon, however, was world-wide. Equally impressive records were obtainable from Switzerland, Scandinavia, Iceland and the United States. Attempts had been made to reconcile these observations with the Bruckner cycle of climate change every 16 years. Professor Speight said, but so many discrepancies occurred that in his opinion precise synchronisation with that period could not be accepted.
In Alaska glaciers had been retreating from 100 to 200 years, the average rate of recession being about 50 feet a year. The Antarctic ice-sheet also showed signs of recent retreat.
“In fact,” said Professor Speight, “no case is recorded of a region of the world in which there are present signs of an advance. This is quite apart from the general retreat since the pleistocene age and may be merely a pacing phase. Its precise significance can only be determined by continued observation.”
“WORD comes from Switzerland that the Alpine glaciers are in full retreat. Out of 102 glaciers observed by Professor P. L. Mercanton of the University of Lausanne and his associates more than two- thirds have been found to be shrinking. Does this mean the approach of a warmer climate, such as swept over our globe thousands of years ago? Will palms, cypresses, magnolias, myrtles and olive trees thrive at the feet of the Adirondacks, as they did in those distant days?”
“Analysis of warming since 1881 shows that most of that increase in global temperature happened before 1919 — before the more recent, sharp rise in the amount of. carbon dioxide in the atmosphere, said Thomas Karl, of the National Oceanic and Atmospheric Administration’s National Climatic Data Center in Asheville, N.C.
While global climate warmed overall since 1881, it actually cooled during the period from 1921 to 1979 before warming again, Karl said.
“In spite of all the well- publicized concern about global warming, you must understand that there is still considerable uncertainty among scientific experts about a number of critical factors which determine global warming,’’ NOAA administrator John Knauss said in a statement,”
