As the effects of climate change become increasingly apparent, some researchers are suggesting we look towards more ambitious solutions to address these issues. Such proposals are known as geoengineering. Science correspondent Miles O’Brien explores one of these concepts aimed at countering the melting of glaciers and sea ice.
This discussion is part of our series, Tipping Point. O’Brien, an Emmy, Peabody, and duPont Award-winning journalist, has been a prominent figure in science communication for over forty years. His reports span topics such as science, technology, climate, and the environment globally.
