Global warming helps remove 14 percent of coral reefs in the world between 2009 and 2018, the largest survey of coral health has been found, the warning that more dynamic underwater ecosystems will likely die if the sea is warmer Corals in South Asia and the Pacific, around the Arabian Peninsula, and off the coast of Australia, is the most difficult blow, according to reports released on Tuesday, compiled by more than 300 scientists in the Global coral reef monitoring network. [Capsaicin Expuu The report stretched data for 40 years, 73 countries and 12,000 sites and found the total area destroyed equal to around 11,700 square kilometers (4,517 square miles) “Climate change is the biggest threat to world reef reefs,” the author with Paul Hardisty, chief executive of the Australian Marine Sciences Institute, said in a statement.
Coral reefs only cover 0.2 percent of the seabed, but they are home for at least a quarter of all animals and marine plants In addition to the sea ecosystem anchor, they also provide food, protection from storms and coastline erosion and work for hundreds of millions of people worldwide This study looked at the 10 regions of coral reef bearings throughout the world and found that reef losses were mainly a reef whitening, but also annoying, unsustainable coastal development and declining water quality.
“There is a trend that is clearly troubling towards coral losses, and we can expect this to continue to warm,” Hardisty said The ocean absorbs more than 90 percent of the excess heat of greenhouse gas emissions and bleaching occurs when coral, under pressure from warmer water, expels colorful algae that live on their network and rotate.
Be careful optimism
A single bleaching event called in 1998 caused by heating waters wiped 8 percent of all corals “Since 2009 we have lost more corals throughout the world than all the corals that live in Australia,” said Executive Director of Unep Engger Andersen The Panel Advisor to the UN Climate Science, IPCC, Project with “High Trusty” that 1.5C Global Warming above the Preindustrial level will see between 70 and 90 percent of all coral missing.
In the world 2c, less than 1 percent of global corals will survive The average surface temperature of the Earth has increased by 1.1C above the benchmark Report entitled: World Coral Reef Status: 2020, found reasons for careful optimism Some reefs show extraordinary capabilities to rise again, which offer some expectations for the recovery of degraded reefs in the future, “Hardisty said.
The coral triangle called East and Southeast Asia, which contains nearly 30 percent of world coral reefs, was beaten less difficult by heating waters and in some cases showing recovery This resilience can be caused by species that are unique to the regions, potentially offering strategies to increase coral growth elsewhere, the author said.
