Five Pacific island went under water

A gradual increase in water level in the Pacific ocean has led to the fact that in 70 years the five small Islands comprising the Solomon Islands have disappeared from the face of the Earth. Experts believe that this event represents an alarm bell as to the archipelago, and for many coastal cities in different parts of the world.

As reported by a study conducted by researchers from the universities of Queensland and Tasmania, the sea level in the area of the Solomon Islands due to global warming and strengthening of winds over the past two decades were up to about 7 millimeters annually. The average rate of water level rise in the oceans make up about 3 millimeters a year, but was expected by the end of this century 7 millimeters per year and will reach this figure.

After analyzing satellite images of the archipelago of the Solomon Islands, made in the period from 1947 to 2014, the researchers stated that the five Islands, the area of each of which ranged from 1 to 5 hectares at this time been fully absorbed by the ocean. Six more Islands in the same period plunged into the water at 20-62 percent. This kind of information was received from people living in this region, the region, and informed. In one of the six drowning Islands are home to 25 families, which since 2011 has witnessed how one went under the water 11 houses.

The gradual immersion of the Solomon Islands in the depths of the Pacific ocean in particular, is a danger to some rare animals, in particular, the number of species of sea turtles and birds, the researchers note.

Scientists say that even if the temperature on Earth will cease year by year to rise, the oceans will still continue to grow, because the delicate balance in the past allowed the glaciers to melt, already broken. This means that even in the most optimistic scenario in the foreseeable future, water will rise by tens of centimeters. In order to prevent more catastrophic scenarios, oceanographers urge more attentive to the problem of carbon dioxide emissions into the atmosphere.

Their work, the scientists published in the scientific journal Environmental Research Letters.
