  1. Impressive! The hottest temperatures ever recorded in Australia (and, for 2012, the US), fires visible from space, and the "sceptics" are going over discredited talking points about the distant past.

  2. Discredited, Anonymous? Any links to the discrediting?

    I didn't think so, but I can give you many links to the discredited IPCC Alarmists.

  3. No anonymous,

    geoff is putting up a paper that is a clue that the climate sensitivity is much higher than previously thought,
    he just does not know it
