Moreover, Hallinan et al. (2015) showed that since the observed auroral emissions depended mainly on magnetic dipole moment and rotation (and may have been weakly coupled to other physical characteristics), aurora may be present at detectable levels even in the faintest T and Y dwarfs and bodies as well as from exoplanets.

Even if global emission rates are stabilized at present — day levels, just 20 more years of emissions would give a 25 % probability that warming exceeds 2 °C.

So climate modelling may not be perfect in the timing, but the end result would still be the same level of temperatures around 2100, so therefore we don't have any room to think emissions can continue at present levels, and the amount of carbon left to burn would not be as high as 800 gigatons.

If Max is correct, and he may well be, with his 50 % take up estimate, it would be reasonable to say, at present levels of CO2 concentrations, an immediate reduction to 50 % of present emissions (which I do realise is just not going to happen!)
