Climate change contributed to mounting food insecurity, poverty and displacement in Africa last year, the World Meteorological Organization (WMO) and partners said, in a report published on Tuesday.
The State of the Climate in Africa 2020 report highlights the continentâs disproportionate vulnerability but also reveals how investing in climate adaptation, early warning systems, and weather and climate services, can pay off.
Petteri Taalas, the WMO Secretary-General, said the climate indicators in Africa during 2020 were characterized by continued warming temperatures, accelerating sea-level rise, extreme weather, and climate events – such as floods, landslides and droughts.
Iconic glaciers shrinking
âThe rapid shrinking of the last remaining glaciers in eastern Africa, which are expected to melt entirely in the near future, signals the threat of imminent and irreversible change to the Earth system,â he warned.
Only three mountains in Africa are covered by glaciers: the Mount Kenya massif, the Rwenzori Mountains in Uganda, and Mount Kilimanjaro in Tanzania. Even though the glaciers are too small to act as significant water reservoirs, WMO underlined their touristic and scientific importance.
Currently, their retreat rates are higher than the global average, and âtotal deglaciationâ could be possible by the 2040s.
Mount Kenya is expected to be deglaciated a decade sooner, the agency added, which will make it one of the first entire mountain ranges to lose glacier cover due to human-induced climate change.
Millions at risk
The report is a collaboration between WMO, the African Union Commission, the Economic Commission for Africa (ECA) through the Africa Climate Policy Centre (ACPC), UN agencies, and international and regional scientific organizations.
It was issued during the extraordinary session of the WMO Congress currently underway online, and ahead of the COP26 UN climate change conference, which opens in Glasgow, Scotland, in less than two weeks.
Increased weather and climate variability is disrupting lives and economies, said Josefa Leonel Correia Sacko, Commissioner for Rural Economy and Agriculture with the African Union Commission.
Estimates reveal that by 2030, up to 118 million extremely poor people on the continent will be exposed to drought, floods and extreme heat, which will hinder progress towards poverty alleviation and growth.
âIn sub-Saharan Africa, climate change could further lower gross domestic product (GDP) by up to 3%, by 2050,â she said. âThis presents a serious challenge for climate adaptation and resilience actions because not only are physical conditions getting worse, but also the number of people being affected is increasing.â
The report estimated that the investment in climate adaptation for sub-Saharan Africa would cost between $30 to $50 billion each year over the next decade, or roughly two to three per cent of GDP.
The authors said rapid implementation of African adaptation strategies will spark economic development, as well as more jobs as part of post-pandemic recovery. Pursuing the priorities of an African Union green recovery plan would also allow for sustainable recovery as well as effective climate action.
