"Ralph J. Cicerone, president emeritus of the National Academy of Sciences and a renowned authority on atmospheric chemistry and climate change, has died. He was 73.

William Kearney, director of media relations for the Washington, D.C.-based National Academies of Sciences, Engineering, and Medicine, said Cicerone died unexpectedly at his home in Short Hills, New Jersey, on Saturday.

Cicerone was the 21st president of the National Academy of Sciences from 2005 until this June. He balanced advocacy for independent scientific advice with maintaining a dialogue with politicians and policymakers on major scientific issues."
