Global warming and freezing of the European

It's an interesting article when I read about the effects of global warming. This article was written based on the results of long-term numerical simulation of what would happen if the greenhouse gases in the atmosphere of the earth to grow further. In the long run, Europe will become increasingly cold as global warming continues. The question is: "What Europe is more cool?"

To overcome this problem, you must first know what one is the Great Ocean Conveyor a global ocean circulation in the circuit occurs transfer of heat energy by the oceans absorbed the tropics, that a relatively constant solar radiation experienced at all times - to middle and high latitudes receive more solar energy is different in winter and in summer (because of the rotation of the Earth's axis that makes an angle of 23.5 degrees on the way).

Due to cold temperatures in the Arctic (Greenland), it will be a freezing of sea water. The freezing of sea water, the salt in sea water release (and why not taste the ice at the poles salty because salt is not frozen). The release of this salt, the salt content rises of sea water, so that the density of sea water to be higher by the sea water mass sinks (known sebaga sink or down Welling phenomenon or can be used as the currents that move in company depth). Vacancy caused by the decline of sea water masses, the high density must be filled by the mass of the surrounding sea water, which runs from the lower latitudes and tropics. Sea water in the warm, tropical climate makes the middle and high latitudes remained warm enough.

Global warming will melt the polar ice caps. This causes the increase in the amount of water, leading to a dilution of sea water. As a result, the density of sea water are reduced so that the process of dumping or below Welling would be weakened. The weakening of this process, the amount of hot water from the tropics. The next episode is the climate in the mid and high latitudes is not as hot as ever, and this will lead to a freezing Europe in the long run.
