As we witness the final days that anyone alive will likely ever again see atmospheric CO2 concentrations below 400 ppm, let’s join together in a vigil for climate action at MIT and help us demand bold climate action leadership from our government and our administration.

350 ppm of CO2 is regarded by many scientists as the safe upper limit to avoid dangerous climate change. Saying farewell to sub-400 ppm CO2 honors an arbitrary milestone, but the passing of this round number gives us time to reflect on the urgency and magnitude of the challenge to meet our planet’s carbon budget – especially with global warming since pre-industrial times set to pass the milestone of 1 °C by the end of this year. It also gives us time to join with students, faculty, and alumni in voicing concern over MIT’s lack of leadership in its plan to mitigate climate change, to celebrate the start of Month 2 of a round-the-clock sit-in outside President Reif’s office calling for a bolder plan, and to demand strong commitments in the coming global climate negotiations in Paris.

Please join us in MIT's Lobby 10 (http://whereis.mit.edu/?go=10) for an evening of music, poetry, and community art-building. Refreshments will be served. Event free and open to the public.
