Jim has advised governments previously through regular channels. But urgency now dictates a personal appeal. Scientists at the forefront of climate research have seen a stream of new data in the past few years with startling implications for humanity and all life on Earth. Yet the information that most needs to be communicated to you concerns the failure of policy approaches employed by nations most sincere and concerned about stabilizing climate. (more…)
