The study, which allowed to find out the speed of the raising water level, is based on a sufficiently large sample of data. The scientists took the informationtransmitted by the satellites for 25 years and subjected her to a detailed analysis by means of computer systems. As it turned out, the warming and melting ice play a major role in accelerating the process of "flooding".
The problem is that previous estimates of the rate of water level were based on old results. And they were not too reliable, because it does not take into account a number of factors, including the accelerating melting of the eternal ice. According to experts, even small changes in the current water level in seas and oceans will greatly affect the state of the environment and coastal towns. So, floods and soil erosion can become constant companions of such settlements.
"The concerns of the residents of such regions can become a reality by the year 2100 — just a few decades," said Kathy Serafin of the University of Oregon. Over the past 25 years, the water level in the oceans rose by 7.5 cm. Approximately half of this growth was due to the melting ice. Now the process of accelerated melting, and more ice starts to turn into liquid water in Greenland and Antarctica.
Rising water, in turn, has a strong influence on the climate, which is changing even faster. In nature a huge number of factors are interdependent, and you can see the example of warming and melting ice. It should be noted that the level of water in the World ocean remained at approximately the same level for about 3000 years. In the 20th century began the changes caused by the industrial revolution, increasing amounts of burned fossil fuels, and other factors.
It is known that the increase in water level has a strong impact on regions like Miami and New Orleans in the United States. These areas flooding is threatening in the first place. And if in normal times, they can cope with rising water, hurricanes and typhoons put everything in its place, causing the flooding of vast areas of land.
At the moment Greenland is having on raising the water level three times a stronger influence than the Antarctic. But ice can melt faster than predicted by current models of climate change used by scientists. "Antarctica appears to be less stable than just a few years ago," — said climatologist Robert Kopp.
In order to slow down the rate at which the temperature of the Earth in Paris in 2016, signed a special agreement between the two countries, which was called "Paris". It regulates measures to reduce carbon dioxide in the atmosphere from 2020. At the moment it is this understanding — the main hope of humanity to stop warming up until you reach the point of no return. Namely, the warming causes the melting of glaciers and permafrost. As a result of increased emissions of carbon dioxide into the atmosphere, increasing the greenhouse effect, warming.
The purpose of this agreement, the retention of growth of average temperature below 2 degrees Celsius. In order to do this, you need to quickly reduce emissions of carbon dioxide into the atmosphere. However, and this may not be enough to stop the warming of the Earth. Some climatologists believe that now humanity is at the point of no return, when you need not only to reduce emissions but also remove greenhouse gases from the atmosphere. Otherwise, the point of no return is passed and will really do something or it will be impossible.
In order to do this, you need to take the following actions: to restore the forests, cultivate the soil special methods to remove carbon dioxide from atmospheric air, and so on. But in order to reduce the restriction in the range of about 2 degrees, you need to learn by the year 2050 every year to remove from the atmosphere about 11 billion tons of carbon dioxide to compensate for emissions. And to make it either difficult or even impossible. In order to achieve significant results, scientists propose to use the entire Arsenal of technologies, which are humanity. Otherwise it may be too late.
