Appenzeller receives 2005 Walter Sullivan Award for Excellence in Science Journalism



When National Geographic began plans to address the issue of global climate change, we asked Tim Appenzeller to write the keystone piece for a series of articles that would document the most recent scientific consensus. His description of the carbon cycle in “The Case of the Missing Carbon” would be a fundamental part of the entire package. To explain that complex, finely calibrated global mechanism to six million readers was the task we set before him.

A daunting task perhaps, but not for Tim Appenzeller, a science journalist with great talent for precise thinking and elegant writing. “The Case of the Missing Carbon” lays it all out, tracing the circulation of carbon between air, land, and water that sustains life on Earth and controls its climate.
