Physicists consider their own carbon footprint

ScienceDaily (Sep. 29, 2011) — In October's issue of Physics World, Phil Marshall, an astrophysicist at the University of Oxford, calls on physicists to pull their weight when it comes to climate change, drawing on his own research showing that astronomers average 23,000 air miles per year flying to observatories, conferences and meetings, and use 130 KWh more energy per day than the average US citizen.

Marshall says that physicists must not only act as "trusted voices" in climate-change debates, but also do all they can to reduce their own carbon footprints.
