    Veerabhadran Ramanathan, Scripps Institution of Oceanography, University of California, San Diego, USA

    Veerabhadran Ramanathan Veerabhadran Ramanathan

    Veerabhadran Ramanathan is Distinguished Professor at Scripps Institution of Oceanography, University of California in San Diego, and UNESCO Professor of Climate and Policy at TERI University, Delhi, India. In 1975 he discovered the strong greenhouse effect of chlorofluorocarbon (CFCs) and along with R. Madden, predicted in 1980 that global warming would be detected by 2000. He was among a team of four, which developed the first version of the community climate model in the 1980s (USA). In 1989, he led a NASA study that used satellite radiation budget instruments to conclude that clouds had a large global cooling effect. 

    He led an international field experiment in the 1990s, with Paul Crutzen, that discovered the widespread Atmospheric Brown Clouds (ABCs) over South Asia, which have devastating health and climate impacts. His recent finding is that mitigation of short-lived climate pollutants (black carbon, methane, ozone and HFCs) will slow down global warming significantly during this century. This proposal has now been adopted by the United Nations Environmental Programme, and 12 countries, including the USA. He now leads Project Surya, which is mitigating black carbon and other climate warming emissions from solid biomass cooking in South Asia and Kenya and is documenting their effects on public health and the environment.


He is on the advisory board of the Stockholm Environment Institute, the Institute for Advanced Sustainability Studies in Potsdam, Germany and the Energy and Resources Institute, Delhi, India. His was awarded with several prizes and been elected to the American National Academy of Sciences, the American Philosophical Society, the Pontifical Academy of Sciences by Pope John Paul II and the Royal Swedish Academy of Sciences.
