Presidential Polar Bear Post Card Project No. 253 - 10.7.16

Lost. #inktober2016 And to some degree this week also marks a major loss in the fight against a warming world. On Monday 10/3 the CO2 concentrations at Mauna Loa observatory reached 400ppm -- and will not likely drop below that mark again for hundreds of years. Not too long ago 350ppm was considered the tipping point for disastrous levels of global sea rise... So important that we focus our energy and intellect on solutions to reducing carbon output and reversing these trends at least as quickly as we have created them. #saveourseaice #advocate #climateaction
