Inferring
external contributions to risk from external contributions to expected temperatures
nStott
et al (2004): assumed internal variability in large-area-averaged temperatures is
unaffected by changing mean climate (no evidence to contrary).
nFit
EV distribution to model-simulated variability, allowing for uncertainty in EV
parameters.
nSubtract possible offsets (change location parameter) due to
anthropogenic influence to generate possible temperature distributions.
nOnly
applies to variables like large-scale temperatures for which we can defensibly
assume no
change in variability.
