A study with 90% probability. shows will have at least 3 billion people was food shortages by the year 2100, due to the Earth's warming.The warming of the Earth, melting has led to rising sea levels. If the period 1962-2003, the amount of the average global sea level rise of 1, 8 mm/year, from 1993-2003 the increase is 3, 1 mm/year. In total, in the last 100 years, sea levels have risen 0, 31 m. According to observations from the satellite, an area of the ice at the North Pole, the South Pole, the ice in Greenland and some of the ice mountains in China is gradually being narrowed. The melting of the ice along with the warming of the climate of the Global Ocean (to a depth of 3,000 m) have contributed to sea level rise. Forecasts to the end of the XXI century, the average temperature will increase from about 2.0-4, 5oC and global sea levels would rise from 0, 18 m-0, 59 m.
