Confused warmist Muller: You shouldn’t be a skeptic of anthropogenic global warming; by the way, we didn’t assess the anthropogenic component of global warming
Muller: 'How much of the warming is due to humans and what will be the likely effects? We made no independent assessment of that'
Skeptical Scientist Matt Briggs: 'Somebody has to remind Muller that skeptics aren't skeptical of that some warming (and some cooling) has occurred. We are skeptics about our ability to explain this warming (and cooling), and to predict skillfully future warming (and cooling)'
