Global Warming and the freezing of Europe

There is an interesting article from Science Daily that I have ever read that discusses the impact of global warming in Europe. This article was written based on the results of long-term numerical simulation of what would happen if the rate of greenhouse gases continue to grow in Earth's atmosphere. In the long term, Europe will increasingly cold turned out if global warming continues. The question is: â € œApa the cause of Europe will be more cool? Â €?

To address this problem, first you need to know about what is called the Great Ocean Conveyor Belt, which is a global ocean circulation in the circulation occurs transfer of heat energy absorbed by the seas of the tropics-which experienced a relatively constant solar radiation throughout the year - to middle-and high-latitude regions that receive different solar radiation energy during winter and summer (due to the earth's rotation axis which makes an angle of 23.5 degrees to the orbit).

Due to cold temperatures around the north pole (Greenland), there will be a freezing of sea water. Freezing of sea water will release the salt contained in sea water (and therefore, why the ice at the poles does not taste salty because the salt does not come frozen). The release of this salt will make the salinity of sea water becomes higher so that the density of sea water there also be higher too, as a result of sea water mass will decrease (known sebaga sinking or downwelling phenomenon or can be referred to as the ocean currents that move into the depths). Vacancy due to the decline of sea water masses that have a large density will be filled by the mass of the surrounding sea water, ie from lower latitudes or tropics. Sea water in the warm tropical climate makes the middle and high latitudes remained warm enough.

Global warming will cause polar ice caps melting. This causes the increase in the amount of water, resulting in dilution of sea water. As a result, the density of sea water to be reduced so that the process of sinking or downwelling would be weakened. The weakening of this process will reduce the amount of warm water coming from the tropics.
