. The US withdrawal from the Paris agreements and the failure by countries of their commitments virtually guarantees that by the end of the century coral reefs almost completely disappear, say experts from the International Union for conservation of nature (IUCN).

«We are one step away from the world where coral reefs are completely absent, and the only way to avoid full implementation of the Paris agreements. We just can’t afford to lose these unique and rich ecosystems, providing food, shelter and protection for around 500 million people,» said Inger Andersen (Inger Andersen), Director-General of the Union.

Colonies of corals are one of the most sensitive indicators of climate change in the ocean. The slightest changes in average water temperature, movement of currents and acidity affect the ability of corals to build calcareous shells. In particular, warming water and acidification prevent the polyps to capture calcium ions and carbon dioxide, which adversely affects the health of reefs.

For this reason, one of the first victims of global warming and rising CO2 concentrations in the atmosphere and the water can become these invertebrate inhabitants of the sea, which often formed one of the most beautiful and important centers of biodiversity on Earth.

The last three years, according to the journal Science David Obura (David Obura), one of the leading oceanographers in IUCN has been particularly difficult for corals due to the abnormally high temperatures that prevailed throughout those parts of the world ocean, where there are the largest colonies of polyps.

He predicted that the United States and other States of the Paris agreements and further increase in the concentration of carbon dioxide in sea water is virtually guaranteed to lead to the fact that coral reefs or completely disappear, literally «dissolving» in zakislenna ocean, or drastically reduce its area.

This, in turn, will lead to the disappearance of a large number of other animals that inhabit today’s coral reefs, but also to what is now the coast of Australia and many other regions of the world will not be protected colonies of coral from storms and erosion. As a result, the lives of the inhabitants of many places on the shores of the Pacific and Indian ocean will be under threat.
