Climate change could spark more violence, mass migration across Asia and lead to a crisis in food supply according to a draft UN report seen by the Independent.
The Intergovernmental Panel on Climate Change is due to publish the second of three reports studying man’s impact on the global climate.
The first part of the research published in January 2014 suggested warming of the climate system is “unequivocal” and “human influence on the climate system is clear”. It found limiting climate change will require “substantial and sustained reductions” of greenhouse gas emissions.
The leaked report suggests “hundreds of millions of people will be affected by coastal flooding and displaced due to land loss”.
It appears to warn this may spark mass migration across Asia and lead to a rise in violence.
Scientific consensus suggests there are dangers should the world be warmed 2°C above its current levels. The draft report claims even low local temperature rises of 1C or more could “negatively impact” yields of major crops such as wheat, rice and maize in tropical and temperate regions.
It predicts climate change could slash average (median) crop yields by up to 2% every decade for the rest of the 21st century.
Demand for food is sure to rise as the world population projected to grow from around 7 billion now to peak at 9.5 billion in 2075.
