Joseph Alcamo

UNEP’s Chief Scientist, Joseph Alcamo shares the result of UNEP’s recent report on Black Carbon and Tropospheric Ozone. He explains how reducing certain particulates can lead to slowing down of global warming, with the caveat that these substances have a short life in atmospheric terms, so cannot be be used to replace long-term action.  He talks about the possible influence on policymakers and further reports planned as a result.
