What follows is that the likelihood of 3 sigma + temperature events (defined using the 1951 - 1980 baseline mean and sigma) has increased by such a striking amount that attribution to the general warming trend is practically assured.

But if you impose a forcing (AGW) which changes the degree of independence, making the tails fatter / less Gaussian, doesn't that mean the forcing ACTUALLY makes the probability of what were once 3,4,5 sigma events MUCH higher than indicated by tamino's method of analysis, which removes these effects?

A similar conclusion to Hansen was reached by Rahmstorf and Coumou (2011)(pdf)-RRB- but for a related but different metric: the probability of record - breaking events rather than 3 - sigma events.

While those rumors eventually turned out to be true, the hard data only amounted to what scientists call a 3 - sigma signal, meaning that there is a 0.13 percent probability that the events happened by chance.

phatboy, I don't think you know what Hansen meant by the 3 - sigma events.

According to Fig 31 inthis «Jason» paper (pointed out on the «Harbinger» thread), for a normal distribution, such a 1 - sigma shift in the mean would increase the probability of an event with an initial 0.001 probability (roughly corresponding to an event that lies > 3 - sigma from the mean [probability 0.0013]-RRB- by a factor of about 20 or so.

Meanwhile, more - severe summer heat waves — classified as five - sigma events — will go from being essentially absent in the present day to covering around three per cent of the global land surface by 2040.

Summary of how they got to this finding: They use CMIP models which, if not outright flawed, have not proved their validity in estimated temperature levels in the 2030 to 2070 timeframe, are used as the basis for extrapolations that assert the creation of more and more 3 - sigma «extreme events» of hot weather; this is despite the statistical contradiction and weak support for predicting significant increases in outlier events based on mean increases; then, based on statistical correlations between mortality and extreme heat events (ie heat waves), temperature warming trends are conjured into an enlargement of the risks from heat events; risks increase significantly only by ignoring obvious adjustments and mitigations any reasonable community or person would make to adapt to warmer weather.

334: Philip: it is by no mean necessary to make a huge number of measurements before observing a 5 sigma event, because the «sigma» is evaluated with the noise WITHOUT the external cause that superimposes to the noise.

Three - sigma events were, by definition, rare and include the French heatwaves, Texas drought and Russian fires.
