Research on solar radiation modification is needed, especially in the Global South, to understand whether it could be an option for reducing climate risk, says University of São Paulo's Professor Paulo Artaxo during a C2GTalk. The planet is currently headed for 3°C global warming, yet the world is still not doing enough to phase out fossil fuels and net zero goals look extremely difficult to achieve.

Paulo Artaxo is a professor at the Institute of Physics at the University of São Paulo, Brazil. He is a member of the IPCC, the Brazilian Academy of Sciences (ABC), the World Academy of Sciences (TWAS), and he is vice president of the Academy of Sciences of the State of São Paulo (ACIESP).
