Hot seawater poses a danger to corals

Warming seawater temperatures will cause a serious coral disease called white syndrome according to the latest report on Australia's largest coral reef in the world published yesterday 8.5 in newspapers. of PLoS Biology.

In 2002, scientists found the level of white syndrome increased 20-fold after a year when the coral reef experienced its second hot summer in history.

Another case is that two years ago, unusually hot seawater across the Caribbean Sea increased the " white " area of ​​the coral reefs here. This is considered a phenomenon different from the white syndrome in Australia but is also identified as a dangerous disease that attacks coral areas throughout the region and consequently there are coral reefs of age Century has died.

This report also points out the impact of seawater temperature also depends largely on the density of the coral area. The explosion of white syndrome often follows the situation of unusually warming seawater temperature in coral reefs that account for more than 50% of the total area.

The submerged coral reefs are formed by tiny organisms and are called tubular unicellular organisms. They are an important habitat for fish and other marine life.

Scientists predict that a quarter of the world's coral has been regularly lost and another 30% may disappear within the next 30 years.
