Nobel Laureate shares concerns over Caribbean priorities
NOBEL LAUREATE Professor Anthony Chen also has grave concerns over the apparent shift in priorities for Caribbean SIDS, while noting the need for a look at emissions even within islands.
“I am most concerned about this inadequacy, and have been for quite a while. I think that there are several reasons for this. One is the attitude that we are insignificant emitters. We are not. Trinidad is one of the highest emitters in the world because of its petrochemical industry, and Jamaica compares to Uruguay and Georgia in terms of emissions of greenhouse gases,” he told The Gleaner.
“The fact is that all countries of the world have to reduce emissions very quickly, and the Caribbean countries that have been strong advocates of climate change action should be leaders in this regard, but, sadly, we are laggards. Another reason is the emphasis on adaptation (reducing the effects of the impacts) at the expense of mitigation (reducing greenhouse gases). I have seen it advocated by one of our leaders that the way to go is to have private enterprise invest in renewables and use most of the funds allocated by the Green Climate Fund for adaptation,” he added.
According to Chen, former head of the Climate Studies Group, Mona, this is “very short sighted.
PRIVATE SECTOR
“Private enterprise will, and can only, invest in small energy plants up to a total 30 per cent of our energy needs. For full mitigation of greenhouse gases, we need to store the energy so that it can be used when there is no wind or sunshine. This can only be done by the use of storage devices, such as batteries or pumped storage. Because of the enormity and expense of such projects, we need the combined effort of Government, with funding from the Green Climate Fund and the World Bank, etc, and private enterprise,” he said.
The 1.5 report – for which a Summary for Policymakers was approved in October at the meeting of the Intergovernmental Panel on Climate Change, whose scientists worked on the document – clearly establishes that 1.5 degrees Celcius is the better option as a temperature goal than two degrees, but makes it clear that to get there will prove a steep climb.
“To limit temperature rise to 2 degrees C, the world as a whole has to peak emissions of greenhouse gases by about 2020, and there should be no emissions by about 2070. To limit temperature rise to 1.5 degree C, much more stringent requirements are needed,” explained Chen.
“Peaking by 2020 or earlier means that no new fossil fuel plants should be added after that date. The option for the Caribbean would be renewables. The 2070 or earlier date means that all fossil fuel plants should be retired by then,” he added.
