A recent report by the Intergovernmental Panel on Climate Change (IPCC) stated that 70 to 90% of warm water coral reefs that exist today will have disappeared by the time we reach 1.5C. At 2C, coral reefs will be vanishingly rare. The sobering reality reported by the World Meteorological Organization is that on our current path, we are heading to global warming of over 3C before the end of this century. This would cause irreversible damage to marine ecosystems and the ocean as a whole. Science and recent experience tell us the consequences would be catastrophic globally â this is clearly something we must avoid at all costs.
