A Blog Around The Clock 
Bora, Bora, Bora… Scientific American has not been a force for informedness, climate wise; John Rennie must be appalled at what it’s become. If you’re saying that the magazine still reliable in other areas, fine; but please, take care you don’t let that [perceived-by-the-public] reputation bleed over into the most important area.
Romm on SciAm’s climate coverage:

Come on – Romm’s histrionics about this have been responded to at length, a long time ago. As a media organization SciAm is not and cannot be an activist – that is Romm’s job.
Yet in many ways SciAm is acting at the forefront of the struggle to persuade people about climate change – it has been pushing climate change harder, with many more articles daily, and started many years earlier, than any other publication in the USA I know of.
