Code Red: not for Earth, for Humanity?

“For the first time in human history, we face a planetary emergency.” Those words were written by Johan Rockström, Director of the Potsdam Institute for Climate Impact Research. Scientists tend to be sober, measured in their assessments and with a preference for others to draw the big picture conclusions. So, when an earth scientist as distinguished and accomplished as Rockström writes that “Human pressures on earth have reached dangerously high levels” which could imperil humanity’s survival, we should listen.

Are you listening? If so, what do you think? And, more importantly, what are you going to do?
