The graph below is
from the work of Max Boykoff, a friend and colleague from here at CU, and Maria Mansfield, University of Exeter. The graph shows a big drop off in media attention to climate change in the aftermath of the Copenhagen conference last December.

When I saw this graph it brought to mind a very similar graph of media attention from about 15 years ago, shown below from a paper that I did with Mickey Glantz in 1995 (on how to "sell" scientific programs to policy makers,
