Caribbean scientists say fishermen are already seeing the effects of climate change, so for a dozen or so years they’ve been designing systems and strategies to reduce the impacts on the industry.
Caribbean Community (Caricom) states are in the process of formulating an energy efficiency building code for the region that would help reduce CO2 emissions, but implementation of the code may depend heavily on moral suasion for its success.
There were surprised gasps when University of the West Indies (UWI) Professor John Agard told journalists at an Intergovernmental Panel on Climate Change (IPCC) meeting in late November 2016 that mosquitoes were not only living longer, but were “breeding in septic tanks underground”.
A few dozen metres from the Caribbean beach of Puerto Vargas, where you can barely see the white foam of the waves breaking offshore, is the coral reef that is the central figure of the ocean front of the Cahuita National Park in Costa Rica.
On Nov. 30 last year, a new high-performance ‘Super Computer’ was installed at the University of the West Indies (UWI) during climate change week. Dubbed SPARKS - short for the Scientific Platform for Applied Research and Knowledge Sharing - the computer is already churning out the ‘big data’ Caribbean small island states (SIDS) need to accurately forecast and mitigate the effects of climate change on the region.
Like many other fast-growing megacities, the Bangladeshi capital of Dhaka faces severe water and sanitation problems, chiefly the annual flooding during monsoon season due to unplanned urbanisation, destruction of wetlands and poor city governance.
As the Global South works to overcome a history of weak institutions, armed conflict and poverty-driven forced exodus, key causes of its humanitarian crises, developing countries now have to also fight to keep global warming from compounding their problems.
The world is still celebrating the Paris Agreement on Climate Change
, the main outcome of the 21st Conference of the Parties of the United Nations Framework Convention on Climate Change
. Its ambitions are unprecedented: not only has the world committed to limit the increase of temperature to “well below 2°C above pre-industrial levels,” it has also agreed to pursue efforts to “limit the temperature increase to 1.5 °C.”
The agreement reached in December, 2015 at the 21st Conference of the Parties under the United Nations Framework Convention on Climate Change (UNFCCC) is a major step forward in dealing with the challenge of climate change. The very fact that almost every country in the world signed off on this agreement is a major achievement, credit for which must go in substantial measure to the Government of France and its leadership. However, in scientific terms, while this agreement certainly brings all the Parties together in moving ahead, in itself the commitments that have been made under the Intended Nationally Determined Contributions (INDCs) are quite inadequate for limiting temperature increase to 2 degrees Celsius by the end of this century relative to pre-industrial levels.
Funding to address the financial flows needed for adaptation and mitigation of climate change remains an issue of concern for the Caribbean.
One of the most significant aspects of the international conference on climate change, concluded in Paris on December 12, is that food security and ending hunger feature in the global agenda of the climate change debate.
Jimmi Jones and wife Sandra Lee’s fish farm in Belize City is unique. His fish tanks supply water and nutrients for his vegetable garden needs and the plants filter the water that is recycled back to the tanks.
Increasing calls for Africa to reduce methane emissions from livestock continue to be met with controversy, and livestock scientists say methane is a forgotten short-term climate pollutant with significant global warming potential that Africa cannot continue to overlook.
Purple garlic that is losing its color? More translucent wine? Climate change will also affect the flavours of our food in the absence of measures to mitigate the impacts of global warming, which are already being felt in crops that are basic to local economies, such as in the Argentine province of Mendoza.
With the effects of global warming becoming more and more visible and the complicated socio-economic decisions indispensable to address this planetary crisis, science needs a new breed of experts: social scientists who specialise in climate change.
