How might the continued increase
in global temperatures affect
Africa - vulnerability
Africa – the major causes for
Temperature rises over many areas will be greater than the global
average. The general predicted rise is 4C by the 2080s. But
temperatures could rise to 7C in southern Africa and 8C in northern
Africa - almost double the global average
Significant changes in rainfall could be experienced across the
continent, with the area around the Sahara and in southern Africa
Desertification is likely to increase around the Sahara, causing
populations to move.
Rising temperatures, widespread water stress, increased frequency
and severity of droughts and floods, and rising sea levels will
severely damage progress on development goals in Africa.
Cereal crop yields could fall between 10 to 30 percent by the 2050s
compared to 1990 levels.
Africa – the major causes for
Heat waves will bring increased injuries and death.
Vector- and water-borne diseases such as malaria,
dengue fever and cholera may increase.An additional 67
million people in Africa could be at risk of malaria
epidemics by the 2080s.
Greenhouse gases must be curbed and help must be
given to vulnerable Africans to adapt to the new climate
conditions. The cost of climate-proofing current
investment plans will be between $10bn and $40bn.
