The list of distinguished signatories includes medical scientists, physicists, and many climate researchers. The Nobel Laureates include Harold Varmus, who headed the National Cancer Institute under President Obama; David Baltimore, the former president of Caltech; and Mario Molina, who helped discover the role of chlorofluorocarbons in depleting the ozone layer. James Hansen, the longtime NASA researcher who had previously denounced George W. Bush’s administration for interfering with his ability to communicate publicly the science of climate change, also signed the letter.
