Re: The heat is on?
To maintain a stable average over fifteen years some of those fifteen years must have been rather colder than the hottest ones. That does not mean that the average over this fifteen years is not hotter than a period of fifteen years starting say 65 or 165 years previously though.
That the CO2 input has increased without a linear increase in temperature out may indicate there are additional factors to consider; there are probably very many, and effort should be (and I believe is being) put into investigating what and how important they might be.
Given however that:
a) temperatures seem likely to increase further (from whatever cause),
then perhaps corresponding effort needs to be put into:
b) quantifying the resultant effects,
and if these are significantly negative,
c) considering whether prevention is (still) possible,
and if that is unlikely/costly/would take too long anyway,
d) how to mitigate the damaging effects.
My problem with "the GCC debate" is that I see far too much bickering from all sides about a) and b), a one-sided response about c) that seems unlikely to stop most of b) anyway, and next to dick-all about d). *sigh*
Oh and if we do d) and a) doesn't happen, so what, we're at least likely to have some nice sea defences to walk on, or whizzy water distribution tech, or have kept some peeps in work in the meantime, or ...
