Melting glaciers and ice caps, cataclysmic storms, rising seas, and longer, hotter summers have fueled concerns that our planet is warming, and prompted heated debate among politicians, scientists, journalists and ordinary citizens. For years National Geographic has been documenting the effects of climate change and its many contributing factors, and modeling the potentially devastating consequences for our environment and societies around the world. Executive Editor Dennis Dimick has overseen this coverage and reporting, working side by side with senior writers, photographers, scientists, and research teams. In this special presentation, Dimick will summarize the data, explaining climate change in layman’s terms, and offer ideas on what we can do to reverse the trends.
