Almost the double the average for the rest of the world’s oceans. Apart from having effects on ecosystems (eg. Melting sea ice, affecting the growth of algae on its surface), warming reduces the ability of the ocean to absorb CO2. There is speculation that global warming could, via closure or decreased thermal circulation, cause a cooling located in the North Atlantic and lead to cooling, or lesser warming to that region. This would in particular affect areas such as Scandinavia and Britain that are warmed by the North Atlantic current.

More significantly, it could lead to an oceanic anoxic condition. The possibility of this collapse in circulation is not clear; There is some evidence for the current stability of the Gulf and possible weakening of the North Atlantic current. However, the degree of weakening, and whether it will be enough for the closure of the circulation, is in debate still. However no cooling was not found in the Northern Europe and nearby seas. Cambioclimatico.com indicates that the American Space Agency (NASA) Icesat satellite has revealed ice from glaciers in Greenland and parts of Antarctica is melting at a record pace, causing the concern of scientists who warn of the significant implications that will have this phenomenon in the future in relation to the increase in the level of the oceans.According to the BBC published today, a British team of experts concluded, after studying the satellite data, that the complete melting of the Greenland ice sheet would raise the level of the sea around seven metres. All the glaciers that are rapidly changing which flow into the sea, recently explained the researcher from the British Antarctic Survey (BAS), Hamish Pritchard.

The U.S. President, Barack Obama, recently launched a passionate appeal to countries to reach an agreement on climate change to avoid an irreversible catastrophe. Although the positions are still distant, and the hardest part is ahead for reaching an agreement at the Copenhagen meeting, in December, that will replace the Kyoto Protocol, the difficulty is no excuse for complacency, said the American President in his appearance at the Summit on climate change that took place yesterday in the UN. 100 Leaders from around the world gathered at United Nations to attend this Forum convened by the Secretary general, Ban Ki-Moon, and zoom positions for a cut in emissions of polluting gases.
