Anthony Watts reads a Science Daily article about a Nature paper on CO2 amplification in the upper atmosphere and concludes that everything is OK! Being a good “skeptic” Anthony unquestioningly accepts the paper’s useful conclusion…
The paper states that empirical evidence for the pre-industrial feedback of CO2 levels on global temperature may be as little as 1/4 of the current best estimate over the past 1000 years. Of course we don’t live in pre-industrial times, do we? None of the time periods studied match today’s conditions. As well, there are some issues with the data that required extra manipulation and so while the result is useful, it’s not definitive.
