It is nearly impossible to read a newspaper or magazine, listen to the radio, or watch the nightly news without encountering at least one mention of climate change. For years, 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.

Quietly, below the roar of the crowd, National Geographic has been documenting the effects of climate change and its many contributing factors, and reporting on scientists’ projections of potential future trends.

Executive Editor Dennis Dimick has overseen this coverage and reporting, working side by side with senior writers, photographers, scientists, and research teams as they gather and analyze the data. He has a unique gift for distilling this vast information into a manageable narrative and he has shared it with a wide range of public and corporate audiences worldwide.

Popular Presentation

Man-Made World: Signs and Scenes from the Anthropocene
Scientists have proposed that we now live in a new geologic epoch called “The Anthropocene,” or age of man. Dennis Dimick, National Geographic’s environment editor, presents a lively and compelling visual tour of Earth’s emerging epoch, and what it means for civilization.

For most of human existence we survived on contemporary sunshine in some form or another, then we discovered coal, and later oil, the energy genies in the earth. Now we live off the power of ancient sunshine (coal, oil, gas), which has made possible the extraordinary expansion of our food supply and our population, including the dramatic jump in just the past half century from about three billion to nearly seven billion people.

We have transformed our finite planet—the land, seas, and atmosphere—with a seemingly infinite expansion of our dominion over Earth. Trend lines show this conquest isn’t sustainable, species are losing habitat and the planet itself is getting cooked. Is it possible to create a soft landing for civilization? Can ingenuity, wisdom, and remaining supplies of fossil sunshine build a bridge to a sustainable future powered once again by contemporary sunshine?

Dimick probes these challenges and opportunities in a presentation based on stories in National Geographic magazine, which in 2011 published a year-long series, “7 Billion”, on population, its impact, and prospect.
