Study: Climate change will lead to annual coral bleaching in the Caribbean

A new study has predicted that if current trends continue and the world fails to reduce greenhouse gas emissions, nearly all of the world’s coral reefs, including many in the Caribbean, will suffer severe bleaching — the gravest threat to one of the Earth’s most important ecosystems — on annual basis.

The finding is part of a study funded by the United Nations Environment Programme (UNEP) and partners, which reviewed new climate change projections to predict which corals will be affected first and at what rate.

The report is published in the journal Nature Scientific Reports. Researchers found that the reefs in Taiwan and the Turks and Caicos archipelago will be among the first to experience annual bleaching, followed by reefs off the coast of Bahrain, in Chile and in French Polynesia.

Calling the predictions “a treasure trove” for environmentalists, the head of the UN agency, Erik Solheim, said the projects allow conservationists and governments to prioritise reef protection.

“The projections show us where we still have time to act before it’s too late,” Solheim said.

On average, the reefs started undergoing annual bleaching from 2014, according to the study.

Without the required minimum of five years to regenerate, the annual occurrences will have a deadly effect on the corals and disrupt the ecosystems which they support, UNEP said.

However, it said that if governments act on emission reduction pledges made in the Paris Agreement, which calls on countries to combat climate change and limit global temperature rise to below two degrees Celsius, the corals would have another 11 years to adapt to the warming seas.

Between 2014 and 2016, UNEP said the world witnessed the longest global bleaching event recorded.

Among the casualties, it said, was the Great Barrier Reef, with 90 per cent of it bleached and 20 per cent of the reef’s coral killed.

New CARICOM chairman to place emphasis on climate change

Prime Minister Dr. Ralph Gonsalves said Monday he would use his six month term as chairman of the Caribbean Community (CARICOM) grouping to deal with the deleterious effects climate change is having on the socio-economic future of the 15-member bloc.

St. Vincent and the Grenadines, St. Lucia and Dominica are now emerging from the effects of a weather system that left a trail of death and destruction over the Christmas holidays.

Caribbean countries have also had to deal with the annual hurricane season and in many cases, like in Haiti, unseasonal rains that cause widespread devastation.

“The big issue…is global warming, climate change. We are having systems affecting us outside of the normal rainy season and the normal hurricane season,” he said making reference to the floods in April last year and the Christmas Eve rains that resulted in the deaths of nine people and hundreds of millions of dollars in damages here.

“There are lots of monies which countries talk about for adaptation and mitigation to climate change. But I haven’t seen the money yet and we have to use our diplomacy as a region and we have to be aggressive with our climate change center in Belize.

“In my term as chairman of CARICOM this is one of the issues which you will recall I said earlier on…I want dealt with during my term in a continued serious and structured way, (and it) has to deal with the deleterious effect of climate change and to get the requisite responses from the international community in relation to this matter”.

Gonsalves told a news conference that the region does not contribute “anything to these man made weather systems, these problems with putting so much carbon dioxide in the atmosphere.

“We are …on the front line,” he said, adding that “this is an issue which is big”.

Gonsalves said that efforts were now underway to stage an international donors’ conference to help the three affected islands recover and rebuild their battered infrastructures.

He said he had already received a letter from Antigua and Barbuda Prime Minister Baldwin Spencer, who is also chairman of the Organisation of Eastern Caribbean States (OECS), outlining plans for an international donors’ conference.

“There is a letter which Baldwin sent to me which I have reviewed and make one or two slight alterations and suggestions, but we have to prepare for a donors’ conference well, maybe in March may be in February… but we have to prepare for it well so that we can get the donors to make pledges,” he said, recalling a similar conference had taken place to help Grenada after it was battered by a recent hurricane.

“I know some of the donors came through and others did not, but at least we need to do that to lift the profile,” Gonsalves said.

The St. Vincent and the Grenadines Prime Minister told reporters that an insurance scheme organized through the World Bank, to which all the Caribbean countries contribute, does not go far enough.

“To the extent that the monies you get from the Catastrophic Relief Insurance System is fairly minimal, but of course every little bit helps,” he said.

Gonsalves said he had already written to the leaders of several countries and was now  waiting to see “what kind of grant assistance we can get because we really need grants preferably.

“The World Bank will give soft loan monies, the CDB (Caribbean Development Bank) will give soft loan monies, the European Union will give grants, Venezuela will give grants, (and) Taiwan will give grants”.
