It seems unthinkable, but for the first time in human history, ice is on course to disappear entirely from the North Pole this year.
North Pole defined as the point in the northern hemisphere where the Earth’s axis of rotation meets the Earth’s surface. The north pole is often credited as having snow. But polar scientists reveal dramatic new evidence of climate change – no more ice at north pole.
The North Pole ice is melting at the highest rate and as a result, there will be no ice. In other words, the pole may be completely ice-free at the surface and composed of nothing but open water by September.
The disappearance of the Arctic sea ice, making it possible to reach the Pole sailing in a boat through open water, would be one of the most dramatic â€“ and worrying â€“ examples of the impact of global warming on the planet. Scientists say the ice at 90 degrees north may well have melted away by the summer.
If it happens, it raises the prospect of the Arctic nations being able to exploit the valuable oil and mineral deposits below these a bed which have until now been impossible to extract because of the thick sea ice above.

Hondaâ€™s new zero-emission, hydrogen fuel cell car called FCX Clarity rolled off a Japanese production line.
A hydrogen vehicle is a vehicle that uses hydrogen as its on-board fuel for motive power. Many companies are currently researching the feasibility of building hydrogen cars. But Honda took a lead and now releasing new zero-emission, hydrogen fuel cell car from a Japanese production line Monday. The Honda FCX Clarity is a hydrogen fuel cell automobile:
The FCX Clarity, which runs on hydrogen and electricity, emits only water and none of the noxious fumes believed to induce global warming. It is also two times more energy efficient than a gas-electric hybrid and three times that of a standard gasoline-powered car, the company says.
Interesting facts on the north pole – there is no land beneath the ice of the North Pole – only thick layer of ice.
I was just wondering about the thicknees of the ice at the north pole. The sea depth at the North Pole has been measured at 4,261 metres (13,980 ft). The nearest land is usually said to be Kaffeklubben Island, off the northern coast of Greenland about 440 miles (c. 700 km) away. The north pole is often credited as having snow but it is factually snowless.
The sea ice at the North Pole is typically around two or three meters thick, though there is considerable variation and occasionally the movement of floes exposes clear water. Studies have suggested that the average ice thickness has decreased in recent years due to global warming.
The Arctic ice cap is a shifting pack of sea ice some 6.5 to 10 feet i.e. 2 to 3 meters thick – floating above the 13,000-foot-deep (4,000-meter-deep) Arctic Ocean. During the winter the Arctic ice pack grows to the size of the United States. In the summer half of the ice disappears.
The Arctic Ocean, located in the northern hemisphere and mostly in the Arctic north polar region. Arctic summer melting in 2007 set new records. The polar ice pack is thinning, and there is a seasonal hole in ozone layer in many years. Reduction of the area of Arctic sea ice will have an effect on the planet’s albedo, thus possibly affecting global warming within a positive feedback mechanism
The most important areas of pack ice are the polar ice packs formed from seawater in the Earth’s polar regions: the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of the Southern Ocean. Scientists in the US have presented one of the most dramatic forecasts yet for the disappearance of Arctic sea ice. In the end, it will just melt away quite suddenly. It might not be as early as 2013 but it will be soon, much earlier than 2040.
From the BBC Story:
Their latest modelling studies indicate northern polar waters could be ice-free in summers within just 5-6 years.
Professor Wieslaw Maslowski told an American Geophysical Union meeting that previous projections had underestimated the processes now driving ice loss.
Summer melting this year reduced the ice cover to 4.13 million sq km, the smallest ever extent in modern times.

Global warming refers to the increase in the average temperature of the Earth’s near-surface air and oceans in recent decades and its projected continuation.Global warming refers to the increase in the average temperature of the Earth’s near-surface air and oceans in recent decades and its projected continuation.
The geographic distribution of surface warming during the 21st century calculated by the HadCM3 climate model if a business as usual scenario is assumed for economic growth and greenhouse gas emissions. In this figure, the globally averaged warming corresponds to 3.0 Â°C (5.4 Â°F).
Now, NEW Zealand scientists hope a newly discovered bacterium that eats methane could ultimately help counter a key global warming gas.
The bacterium was discovered living about 30cm below the ground in the hot, acidic environment at Hells Gate in Rotorua, a geothermal area.
