Subject: Environment

Section: Climate change

Context:

Global Coral Reef Monitoring Network (GCRMN) has released a report on the status of coral reefs across the world.

Concept :

Research details:

• Global warming poses a more significant threat to coral growth and reef accretion than ocean acidification (OA), according to a new study.
• As temperatures rise, mass coral bleaching events and infectious disease outbreaks are becoming more frequent.
• Carbon dioxide absorbed into the ocean from the atmosphere has already begun to reduce calcification rates in reef-building and reef-associated organisms by altering seawater chemistry through decreases in pH.

About the Global Coral Reef Monitoring Network (GCRMN):

• The Global Coral Reef Monitoring Network (GCRMN)​ is an operational network of the International Coral Reef Initiative (ICRI) in 1995 aiming to provide the best available scientific information on the status and trends of coral reef ecosystems for their conservation and management.
• The GCRMN is a global network of scientists, managers and organisations that monitor the condition of coral reefs throughout the world, operating through 10 regional nodes.

International Coral Reef Initiative (ICRI):

• The International Coral Reef Initiative (ICRI) is an informal partnership between Nations and organizations which strives to preserve coral reefs and related ecosystems around the world.

GCRMN is an implementing arm of ICRI, supporting its efforts by working through a global network to strengthen the provision of the best available scientific information on, and communication of, the status and trends of coral reef ecosystems, for their conservation and management.
