This accepted sensitivity doesn't take into account feedback effects,
as far as I know. There can be no stable sensitivity to a non-linear
response - least of all a step change, which we may soon be facing as
we spiral all the way out of the ice-age into a 'hothouse earth'
state.

Exactly and I don't think you can define it easily -- it ha
Manu--Given that the observed preindustrial global baseline is not all that
well known, 2 F above present (of course, one has to worry how that is
precisely defined as well) may be a more definitive target than 2 C above
the baseline. Of course, one could base the changes all on calculations in

Mike,

Interesting.
So, 2 C above preindustrial is the official goal by the leaders. We have
warmed by 0.8 C, so that means we have about 1.2 C to go. Convert that by
multiplying by 1.8, and that gives a bit over 2 F to go from present
warming. I guess the larger number makes people think we have a bit m

Fundamentally, although limiting the temperature rise to 2 degrees
Fahrenheit is an accepted goal, there is no consensus on how to get there.
This 2-degree Fahrenheit rise is the equivalent of the original goal of 2
degrees Celsius above the planet’s temperature
