Temperatures in the Arctic are rising much faster than elsewhere on Earth resulting from a shift in global climate patterns and the sea ice on the North Pole melting much quicker than expected.
The Arctic ice has undergone a 40 percent reduction from the mid-1990s, according to the US National Snow and Ice Data Center. As well, glaciers on Greenland are declining at an unprecedented rate.
Water temperatures between Alaska and eastern Siberia have risen by 5C degrees since the early 1990's. According to studies by a team of US, Norwegian and German researchers there has been a dramatic change in atmospheric circulation patterns with the high pressure in winter shifting toward the northeast.
An emerging new pattern of sudden climate change has been identified as "poleward atmospheric and oceanic heat transport." The discovery was made by using specialized filters to accurately observe changes to high-pressure centers over time.
Many scientists believe that climate change in the Arctic has already reached the point of no return that would result in irreversible developments for eco-systems and humanity. A complete disappearance of Arctic ice during the summer months would magnify global warming, due to the fact that bright white ice reflects sunlight back into the atmosphere whereas dark colored land and ocean absorbs heat.
Winter in the Arctic has long been determined by what's known as the "tri-polar" pattern - the interaction among the Icelandic Low, the Azores High and the subtropical high in the Pacific that led to primarily east-west winds, which blocked warmer air from moving northward into the Arctic region. But since the beginning of the decade, the patterns have changed. Now, a bipolar pattern has developed resulting in the Artic winds blowing north-south with the warmer air from the south blowing into the Arctic region.
A dramatic disappearance of Arctic ice observed in 2007 is just the preview of what's going to happen in the near future. The progression has become crystal clear and in the years not far ahead the ice cap will become so small that it will not be able to survive the warm summer months.
The series of warm winters experienced in the Arctic this decade is not the first time in recent history that the North Pole has had mild weather. In the 1930's warm air pushed into the Arctic due to the air pressure from the North Atlantic. The difference today is that the rising heat is spread throughout the entire Arctic region resulting from a change in the pressure systems in the Northern Hemisphere that's been directly attributed to human-made global warming.

Floating ice supports the ends of glaciers, if an ice shelf goes, land ice melts into the sea at a faster rate as the glaciers accelerate.

But as the ice melts, it contracts. Which is why it was floating in the first place. And why pipes burst when they freeze. Another factor is that as the glaciers disappear, the land rises as it is relieved of their wieght. Adjacent land sinks. This is happening in the UK right now.

The ice contracts but it still weighs the same and even after contraction it still occupies slightly more volume than the same weight of sea water simply because it is fresh water, and salt water is denser.
Yes I'm standing on a piece of formerly glaciated UK, in a glacial valley. Yes the land is still rebounding from the last ice age. But no, adjacent land doesn't sink, as such, although a solid mass might tilt a bit. If you get off a boat it rises, and may pitch a little but the adjacent boat doesn't sink. But this has little to do with the next century's sea levels, the rising land may apparently lower sea level locally and may displace a little sea, and so raise levels globally, but most of it was above sea level anyway and it is a slooow process taking tens of thousands of years. Remember how long ago the last ice age was?

As the ice melts, its upper surface - the top of an iceberg - sinks. But that isn't what's counted as "sea level". When ice melts into salty water, the *liquid* surface *rises*. So melting ice that's floating on oceans does cause a rise in sea level. Do an experiment, if you don't believe me. Half-fill a glass with cold salty water. Add an ice cube, so it floats on the water without jamming against the side of the glass. Make a mark or stick a bit of tape on the glass to show the level of the liquid surface. Then wait for the ice to melt. You will find that the level of the liquid surface rises. -> Another factor is that as the glaciers disappear, the land rises as it -> is relieved of their wieght.

There is both salt water ice and fresh water ice. Fresh water ice is from glaciers sliding into the sea where this happens. But the sea also freezes making salt water ice.

-> Harry K
Quite so. But, as you said, sea water does NOT freeze into salty ice. When sea water freezes, the ice produced contains almost no salt.
dow
Okay and you now have fresh water that was frozen out of the sea and is being supported as ice. When it melts it adds that water back into the sea - no sea level change. It doesn't matter one wit whether the ice is salt or fresh, it displaces its own mass either way, salt/fresh ice/liquid.

Otto, all the man-made nonsense is silly, to say the least. Take a close look at the earth's motion in orbit about the sun, including factors like nutations and precessions. Check your classical mechanics textbook if you've forgotten the natural behavior of an orbital body when coupled with the motions of a rigid body in three dimensions. As a physicist, I will agree that the math is a bit intimidating, and well beyond the graps of the of someone like Al Gore. Still, it is a scientific fact.
For those capable of understand the consequences, it simply implies that the earth will undergod periodic shifts between global warming and ice ages. Man has no control at all over these cycles. The question in science is simpy are we heading for a period of gobal warming (turning out continents into another gigantic rain forrest, or are we headed for the next ice age. Nobody in science really know with any degree of certainty.
The thing that science tells us it that man's influence on climate change is at best minimal. Among the non-scientists and the media people, this is hard to accept, because it doesn't make great news, and they alread have pre-conceived stupid opinions bases on total ignorance.
So yes Otto, I must be one of those retards that you cite because I believe it is BULLSHIT.
For what it's worth, I earned my BS at Drexel, and my MS from Princeton. The first in physics and the second in electrical engineering.
Please post your educational credentials, so we can play on a level playing field.

So you are just ignoring all the scientific evidence that shows the climate is warming faster (and accelerating) than any time for which records are availabe...and that goes back 100s of thousands of years for ice cores.
No.
He's saying it is most likely a natural phenomenon of the sun and earth's workings.
If you would take an honest look (lhopeless for you) you would see that there are two things working, a natural cycle AND man made actions that are contributing to it.
