"Global climate model projections for sea ice trends around Antarctica are at odds with what is being observed. Nearly all models to date project a slight decline in sea ice extent at present and for the next several decades. The mismatch between model results and observations is a topic of research, and a basis for investigations to find the processes that must be added to the models to align them with what is observed. However, analysis of the variability of Antarctic sea ice in models shows that it is possible that the current trend of increasing sea ice extent is a result of the high variability in the Antarctic sea ice and climate system." - US NSIDC FAQ

In the 1970s "climatologists" predicted an impending ice age (incorrect) based on the (correct) observation the world was cooling.

Hubbard Glacier defies climate change, continues advancing

Jun 13, 2015 - Hubbard Glacier could permanently dam the entrance to Russell Fiord within 25 years

Stearns says the Hubbard Glacier is unusual because it has been steadily advancing for more than 100 years despite warmer temperatures. The glacier is accumulating mass near its origin faster than it's losing it in the ocean.


2015 Antarctic maximum sea ice extent breaks streak of record highs

“After three record high extent years, this year marks a return toward normalcy for Antarctic sea ice,” said Walt Meier, a sea ice scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

"Scientists believe this year’s strong El Niño event, a natural phenomenon that warms the surface waters of the eastern equatorial Pacific Ocean, had an impact on the behavior of the sea ice cover around Antarctica."

On Sept. 19, 2014, the five-day average of Antarctic sea ice extent exceeded 20 million square kilometers for the first time since 1979, according to the National Snow and Ice Data Center. The red line shows the average maximum extent from 1979-2014.

It was abnormally cold recently and ice grew

New data arises on growth in glaciers in Denmark and Greenland and the rapid growth in glacier size after the 1940s.

"In the early 1920s and 1930s, temperatures were high, similar to that of the present, and this affected the glacial melt. At the time many glaciers underwent a melt similar or even higher than what we have seen in the last ten years. When it became colder again in the 1950s and 1960s, glaciers actually started growing," says Dr. Kurt H. Kjær "

"Results showed that the sea ice extent has been far from stable throughout the last 10,000 years. Read the scientists' newly published paper in Nature: GeoScience

The link above is to a newspaper article about this paper in Nature. The Danish and Greenland government had been squabbling over a border for decades and took photographs every day of the area; recently these very good photos of the glacial coastline growing post 1940 were found and analyzed.

Turns out the Greenland ice sheet does this every 150 years

"Ice cores from Summit show that melting events of this type occur about once every 150 years on average. With the last one happening in 1889, this event is right on time," says Lora Koenig, a Goddard glaciologist and a member of the research team analyzing the satellite data."

It's not supposed to be there today.

September 19, 2013 by Dennis Avery

Churchville, VA—The naive advice of ardent activists can kill.

Last spring, Paul Beckwith of Sierra Club Canada predicted that the Arctic seas would be ice-free ice this summer. This exciting adventure opportunity attracted a variety of yachts, sailboats, rowboats, and kayaks owners to try sailing the fabled Northwest Passage.

The Arctic sea ice suddenly expanded 60% this fall, after the coldest summer in the modern Alaska temperature record. The passage is now impassable. More than a dozen of the boats are trapped, apparently even including a group of tiny American jet-ski “personal watercraft” that were attempting to cross from the east coast of Russia to the North Atlantic. Arctic observers are now warning that even Canadian icebreakers might not be able to rescue them.

I guess that's the opposite of sea rise
