New research by a team at the University of the Witwatersrand (Wits) shows that, in only nine years, Africa has gone from being a net carbon sink to being a net carbon source.
Researchers from the Future Ecosystems for Africa programme, based at Wits, found that between 2010 and 2019, the continent has made the transition.
It is estimated that Africa is a source of 4,5 petagrams, or 4,5 billion tons, of carbon dioxide
