Ocean waters and land

Ocean waters and land have long ceased fighting among themselves. Tides, invading land, blurred the shores and carried away with outflow from the shore rocks. Storm waves and coastal currents intensified the destructive work of the tides. Not content with direct attack, the ocean attacked the enemy's rear with a detachment of rain clouds. Streams fed by rains, mountain streams and more calm flat rivers destroyed the surface of the land. At the same time, they dissolved everything that can be dissolved in the rocks that form the land, carrying its prey to the ocean. This struggle, which began many hundreds of millions of years ago, continues to this day.

The fact that the waters of the Adriatic Sea flood Venice are not new. But it turned out that such a threatens another city of Italy - Ravenna. Over the past 80 years, the land on which the city stands has fallen almost half a meter, that is, twice as much as in Venice. In addition, the sinking of land continues steadily.

Evidence of the seriousness of the emerging relationship between ocean waters and land can serve as semi-flooded cities in the northern US states - Carolina and Virginia, as well as the rapid water offensive in the area of the Egyptian city of Rashid, where over the past 15 years, it "won" at the land about 3 km.

The war, which is led by ocean waters and the land is very disturbing and the Japanese. For example, in Japan in 1985, the land dropped noticeably in 60 points, of which 12 more than 4 cm. The strongest descent of the land - about 10 cm - was observed near the city of Niigata. It also turned out that Japan's largest city, Yokagama, is already 6,4 cm below its original level.

Water flooding threatens not only coastal cities. In Paris, for example, many cellars and underground garages sometimes turn into pools. The case in groundwater, according to experts. For many years, groundwater has been pumped out, and now they are returning to their original level. Because of the dry summer and the fall of the groundwater, the slope of the famous Leaning tower of Pisa, the Brazilian city of Olinda, called the "treasure of Portuguese architecture", is threatened with the danger of a gradual immersion in the Atlantic ocean waters.

Scientists came to the conclusion that in our century, the rise of the world ocean will be 60% and is due to the melting of relatively small glaciers, as well as ice caps covering the mountain peaks. This conclusion contradicts the theory, which lays the main blame for the gradual melting of powerful ice shields Greenland and Antarctica. The thing is that with increasing average temperatures, small glaciers and ice caps covering the mountain peaks begin to melt much faster than giant ice sheets several kilometers thick. The calculations showed that the melting of compact ice massifs becomes the main reason for the inflow of water into the world ocean - at least until the year 2100. These calculations allowed us to revise the projected scales of the upcoming global flood. It follows from them that in our century the level of ocean water will rise by 27-97 cm.
