In a new report, the World Bank warned 100 million more people could be pushed into poverty by 2030 unless action was taken to prevent global warming.

It said increasing temperatures would ravage crops and fuel the spread of malaria and other diseases.

Up to 5 percent, or more than 150 million, more people could be affected by diarrhoea with warming of 2-3°C, with an estimated 48,000 additional deaths among children under the age of 15 from diarrhoea by 2030.

“Good” development with climate change in mind – such as expanding programmes that reduced poverty while increasing people’s capacity to cope with shocks – would help, it said.

Those efforts would need to be coupled with “targeted climate adaptation measures”, such as infrastructure like dikes and drainage systems, mangrove restoration to deal with flooding, and the introduction of climate-resistant crops and livestock breeds.
