Andrew Revkin

[1] While at Columbia, he launched a video webcast, Sustain What,[2] that seeks solutions to tangled environmental and societal challenges through dialogue.

[12] Revkin has also written books on the Anthropocene,[13] humanity's weather and climate learning journey,[14] the once and future Arctic, the Amazon, and global warming.

"[16] Revkin is among those credited with developing the idea that humans, through growing impacts on Earth's climate and other critical systems, are creating a distinct geological epoch, the Anthropocene.

The group is charged by a branch of the International Commission on Stratigraphy with gauging evidence that a formal change in the Geologic Time Scale is justified.

[19] His first album, A Very Fine Line, featuring guest contributions by Dar Williams, Mike Marshall and Bruce Molsky, was released in November, 2013.

Andrew Revkin reported for The New York Times in 2003 from a research camp set up on sea ice drifting near the North Pole. Scientists erected the sign, then added "was" as currents were pushing the ice several miles a day.
