The talking point this morning is going to be the history of the use of the term "lukewarmer" at the Making Science Public blog. It focuses on its appearances in the mainstream press, and thus misses the older history, going right back to the late John Daly. Nevertheless it's fun to see the way the term crept into the legacy media after doing the rounds of new media for years beforehand.
It would have also been interesting to juxtapose the term against the responses from the mainstream, principally the use of the d-word. Mind you, in the era when even President Obama is casually referred to as a climate denier for not toeing the green line, you can see that you are dealing with desperate attempts to smear rather than to enlighten.
