Based on the consensus you are right Alastair, but keep in mind that
30% of the temperature increase is due to non-manmade causes, says
the IPCC. So if that 30% goes to 50%, then it's fifty-fifty nature
vs. manmade.

The IPCC in fact say that up to 30% of the warming SO FAR was due to
natural causes. As AGW increases that figure will fall, not rise.

Actually 30% of the rise and all (100% of the cooling which just nicely
cancells 30% of the warming) of the cooling which overall balanced each
other out.

Natural factors cancelled overall, so separating it into the 30% warming
does not make a lot of sense when talking about the overall sum. ALL of the
resulting warming was due to GHGs.
