Coral reefs likely to disappear from planet by mid-century

Prague: Coral reefs are likely to disappear from the planet by mid-century even if world leaders agree on efforts to limit temperature increase to less than two degree Celsius by the end of the century at December’s Climate Change Conference (COP21) in Paris, scientists have warned.
coral reef“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,” said professor Peter Sale from University of Windsor in Ontario, Canada.

Speaking at a plenary session of the ongoing Goldschmidt 2015 conference, one of the world’s major gathering of geochemists, in Prague, Czech Republic, Sale said he sees little hope for reefs unless the world embarks on a more aggressive emissions reduction plan.

“This is now serious; 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 pointed out.

Coral reefs are hot spots for bio-diversity and crucial for the economies of many coastal communities.

Besides providing habitats and shelter for many marine organisms, they protect coastlines from the damaging effects of wave action and tropical storms.

They are now considered one of the most vulnerable ecosystems to future climate change due to rising sea surface temperatures and ocean acidification, which is caused by higher atmospheric levels of carbon dioxide (CO2).

“Aiming for CO2 at 350 ppm (parts per million), or a total warming of around 1C is scientifically defendable, and would give reefs a good chance; a number of coral reef scientists have called for this,” Sale noted.

“This is a global emergency, which requires us to decarbonise within the next 20 years, or face temperatures that will eliminate ecosystems like coral reefs, and indeed many systems that humans depend on,” said professor Ove Hoegh-Guldberg from University of Queensland in Australia.

Countries in Climate Talks Move to Produce a Draft To Combat Climate Change

The text still contains some wording in brackets, denoting it has yet to be agreed, but less than previous drafts.

Negotiators from nearly 200 countries produced a draft text Thursday on how to implement the Paris Agreement on combating global warming, but some disputes remain with only one day left before the official end of the conference.

The presidency of the climate talks in Katowice, Poland, had asked for a draft of the final package to be ready by Thursday afternoon after almost two weeks of negotiations, but work continued into the evening to get it ready.

The draft lays out options on ways to implement the 2015 Paris pact which aims to limit global warming to “well below” two degrees Celsius.

“We can implement the Paris Agreement as you all designed it. It is now time to move forward. We need to move. Climate change will not wait for us,” Poland’s Michal Kurtyka, president of the talks, told delegates.

Ministers are expected to continue working on sticking points through the night into Friday.

Disputes over finance have been a stumbling block at the talks, as well as monitoring and reporting countries’ efforts to reduce emissions. The United States, which intends to withdraw from the pact, is trying to ensure a level playing field for U.S. businesses against China.

“Money is the most difficult part of it. This is all money talk. This (meeting) is about technical decisions although it turned political,” one delegate told Reuters.

Groups of small island states and poorer countries, representing over 920 million people, issued a statement to Kurtyka expressing their frustration with the slow pace and lack of ambition of the talks.

“(We are) deeply concerned over the direction in which the outcomes … are heading,” the statement said, adding that a robust rulebook is needed to ensure ambitious emissions cuts are made.
