    ZM. Yes it is the warming affects that are delayed (as far as I understand), that is what is being said in your quoted text.
    Sorry to be brash in my posting (to Tony and Ivor as well) that wasn’t my intention, at times I get frustrated by some of the discussions.

  2. MartinK, no worries 🙂 I never studied science above about year 9 so any clarifications and corrections are welcomed

    Ivor: where was the recession in 2014-15? The inflection of GHG emissions – attested by three reputable sources, links here – took place during a period of normal growth. It reflects major policy changes in China, where the leadership feels threatened by massive air pollution. Among a host of other anecdotal evidence, Arch Coal in the USA has just filed for bankruptcy and Adani has shelved the Carmichael coal mine. I don’t see why you won’t believe the report. The Mauna Loa CO2 measurement is the gold standard, but you would expect a lag.

    There is no inflection of CO2 in your link.

    However the growth rate of CO2 in 2015 was the highest ever (except for 1998) judging by

    Annual mean carbon dioxide growth rates based on globally averaged marine surface data.

    The Mauna Loa data does not appear to show any variability due to recessions – so it is long-run economic growth that is the problem.

    We should ignore ups and downs due to booms and busts.
