‘We will have algal-dominated, rubble-strewn, slowly eroding limestone benches’
Limiting global warming to 2 degrees Celsius may not be enough to save ocean ecosystems, according to scientists.
FRISCO — Even if this year’s COP21 talks in Paris result in a global climate treaty, it may not be enough to save the world’s coral reefs. A global temperature increase of 2 degrees Celsius — targeted by the talks — means most reefs could be dead by mid-century, according to presentations at the Goldschmidt conference in Prague.
Speaking to the world’s major gathering of geochemists, Professor Peter F Sale (University of Windsor, Canada) spelled out the stark choice facing climate scientists in the run-up to the Paris conference.
“Even if Paris is wildly successful, and a treaty is struck, ocean warming and ocean acidification are going to continue beyond the end of this century,” Sale said.
“I find it very unlikely that coral reefs as I knew them in the mid-1960s will still be found anywhere on this planet by mid-century. Instead, we will have algal-dominated, rubble-strewn, slowly eroding limestone benches,” Sale said. Continue reading
