Importantly,
the upper uncertainty bounds of the new estimates are much lower.»

Of course this approach is a nonsense far beyond what Michael Tobis is complaining about, since there is no hard
upper bound to the
uncertainties.
However, taking account of sampling
uncertainty (as most more recent detection and attribution studies do, including those shown in Figure 9.9) makes relatively little difference to estimates of attributable warming rates, particularly those due to greenhouse gases; the largest differences occur in estimates of
upper bounds for small signals, such as the response to solar forcing (Allen and Stott, 2003; Stott et al., 2003a).
In particular, a Gregory - 02 lower
bound estimate is more reliable than their median value, given the
upper bound uncertainties.
Given that and
uncertainties about the location / exposure of evacuees and also the reliability of the LNT model at low doses, they say that
upper bound mortalities and morbidities could be increased to 1300 and 2500, respectively.
Based on a TCS
upper bound of 1.6 o C that we determined from actual data, we compute a 2.9 o C
upper bound for GHG ECS that is below the mid-point of the latest IPCC GHG ECS
uncertainty range of 1.5 < ECS < 4.5 o C and 71 percent lower than maximum 10o C ECS values obtained from the IWG statistical distribution for ECS.
Taking both the
upper limit of the 4 — 5 C warming range and a lower limit for the forcing change, deducting Kohler's 1.9 W / m2
upper limit of
uncertainty from the 9.5 W / m2 change in forcing, implies an
upper bound for the ECS estimate of 2.44 C.
