We believe that, as scientists, it is our responsibility to act upon the finding of the scientific community that we must rapidly reduce our carbon emissions in order to avoid the worst consequences of global warming. Thus, we are exploring ways to conduct our science with a minimal carbon footprint. This includes generally avoiding the use of air travel to attend meetings and conferences.
We encourage other scientists consider what they can do to reduce the impact of their science. Take the Jump and this free New York Times article describe steps that ordinary citizens can take to reduce their impact. Labs with so-called "minus 80" freezers can consider setting them to -70C, a change that saves the equivalent emissions of a typical household without affecting sample quality.
