Nobelist Mario Molina Public Lecture on Air Quality in Beijing and Mexico City

February 10, 2017

A Nobel Prize-winning chemist who identified the cause of the atmospheric ozone hole has called for new studies into air pollution in the world’s megacities, arguing that differing local conditions mean the world cannot rely on cookie-cutter solutions created in highly developed cities like Los Angeles and London.

Mario Molina, who in the 1970s identified chlorofluorocarbons, widely used as refrigerants, as a threat to atmospheric ozone, used examples of efforts to curb pollution in Mexico City and Beijing to Read more about Nobelist Mario Molina Public Lecture on Air Quality in Beijing and Mexico City

New York Times Cites China Project Symposium and Investigation

July 14, 2014

Changing regional climate might be increasing atmospheric stagnation in northern China in winter, contributing to recent severe haze episodes. This is an area of active investigation in the atmospheric science community, both within China and beyond. It was one topic explored at a Harvard China Project symposium, "China 2035: Energy, Climate, and Development," held June 18-19 at the Harvard Center Shanghai with leading Chinese scientists, economists, and policy analysts.
