It would be good if there was a global map showing where human caused emissions are happening in real time (roughly) so that the people of the world can make informed decisions as to which causes to support. My check of sites in this area show there are some very useful statistical summaries of the problem and I recommend a quick surf. But the coup d'etat would be that one picture of the globe showing the hot spots that need to be repaired the fastest for the global good.
