The World Bank said in a new report that the temperature rises would cut into yields of crop and supplies of water in numerous areas and probably pull back the efforts of bringing out of poverty the population.
The report said:
“Climate change poses a substantial and escalating risk to development progress that could undermine global efforts to eliminate extreme poverty and promote shared prosperity. Without strong, early action, warming could exceed 1.5-2 degrees Celsius and the resulting impacts could significantly worsen intra- and intergenerational poverty in multiple regions across the globe.”
It is already very likely the temperatures will rise by 1.5 degrees Celsius from levels before the industrial levels, based on the impact of greenhouse gas emissions, said the World Bank. Frequent tropical cyclones, the rise of sea level and extreme events of heat could now be unavoidable. But the real threat is that the global temperature could increase by 4.0 degrees Celsius by the end of this century.
The bank called it a terrifying world of global instability and increased risks.
World Bank president Jim Yong Kim said:
“Ending poverty, increasing global prosperity and reducing global inequality, already difficult, will be much harder with warming of two degrees Celsius. But at four degrees, there is serious doubt whether these goals can be achieved at all.”
The yield of soybean crops from Brazil could be lowered by 70 percent because of an increase of only two degrees Celsius. Andean cities could be threatened by melting glaciers and West Indian and Caribbean communities on the coast may see a decline in fish supplies. Yields of wheat, grape and corn crops in Macedonia could be lowered by 50 percent because of a two degree warming.
Kim said it is possible to reduce world poverty around the world if the limit of the warming is set to just two degrees as the World Bank has the target of eliminating poverty worldwide by 2030. But the temperatures have already risen by 0.8 degrees Celsius since before the industrial era, and the recent study it’s probably too late to prevent a 1.5 degrees rise in temperature.
In North Africa and Middle East agriculture and water resources will be exposed to critical dangers because of the warming.
