Its late the for the Military to be engaging with the security implications of climate change, but better late than too late. So is it too late?
When cure is not possible, prevention acquires special top-status and this needs a clear global plan.
Jim Hansen's figures suggest its already too late. We emit globally CO2 emissions to the weight of 7.5 gigatonnes carbon [GTC] annualy at this time.
That brings the current atmosphere total to 820.05 GTC [385 ppmv] and that represents a 40% odd rise against the pre-industrial value of 596.4 [280 ppmv] and the rise is accelerating.
Jim Hansen's quoted figure for the 'tipping point' is the 1990 value of 745.5 GTC [350 ppmv] which augurs badly for those who maintain it is not already too late.
However, on the latest 'coupled' carbon cycle modelling, not exceeding 958.5 GTC [450 ppmv] requires a net zero emissions output globally by c. 2060 i.e. around no more than 250 GTC from all sources - see: -

I hope it isn't but if it is already too late . . . what exactly are the military planning for . . . ?
