Climate researcher questions Cyclone Marcia's category 5 status Jennifer Morohasy said the bureau had
used computer
modelling rather than
early readings from weather stations to determine that Marcia was a category 5 cyclone, not a category 3... Systems Engineering Australia principal Bruce Harper, a
modelling and risk assessment consultant who analyses cyclones, said it was often difficult to determine whether a storm was a marginal 3, 4 or 5.
Judith, I think falling best estimates for aerosol offsets in the SOD (compared to AR4) and simultaneous continued
use of
earlier (larger) aerosol offsets in the
climate model simulations borders on daft.
Italian flag analysis: 30 % Green, 50 % White, 20 % Red (JC Note: all
climate models produce this result in spite of different sensitivities and
using different forcing data sets; the
models do not agree on the causes of the
early 20th century warming and the mid-century cooling and do not reproduce the mid-century cooling.)
The institute's
early study of the Earth and planetary atmospheres
using data collected by satellites, space probes, and space probes eventually led to GISS becoming a leading center of atmospheric
modeling and of
climate change.
An
earlier version of the PAGE
model was
used in the UK government's 2006 Stern Review on the Economics of
Climate Change to evaluate the effect of extra greenhouse - gas emissions on sea level, temperature, flood risks, health and extreme weather while taking account of uncertainty7.
In comparison, the researchers say that a number of the global
models used in previous studies of future
climate change predict too frequent precipitation that often falls too
early in the day.
The researchers
used data on
earlier warm periods in Earth's history to estimate
climate impacts as a function of global temperature,
climate models to simulate global warming, and satellite data to verify ongoing changes.
When you respond in more detail later, it will help if you tell us your
model (or possible
models) of
climate variability over the Holocene era; or perhaps why you think some
earlier swings in
climate are of little relevance; or exactly what
model you
use in your attribution, if not what I have outlined.
So is this the basic disagreement: Gavin thinks that the
climate models are good enough that they can be
used for attribution, and Curry thinks that they clearly are not good enough, since the issue that we're discussing, CO2 vs. natural variation, is exactly what the
models are failing to capture, both
early in the last century, and during the «pause»
early in this century.
«The assessment is supported additionally by a complementary analysis in which the parameters of an Earth System
Model of Intermediate Complexity (EMIC) were constrained using observations of near - surface temperature and ocean heat content, as well as prior information on the magnitudes of forcings, and which concluded that GHGs have caused 0.6 °C to 1.1 °C (5 to 95 % uncertainty) warming since the mid-20th century (Huber and Knutti, 2011); an analysis by Wigley and Santer (2013), who used an energy balance model and RF and climate sensitivity estimates from AR4, and they concluded that there was about a 93 % chance that GHGs caused a warming greater than observed over the 1950 — 2005 period; and earlier detection and attribution studies assessed in the AR4 (Hegerl et al., 2007b).&r

The current generation of global atmospheric
models in
use for
climate studies around the world do some things remarkably well, as I've tried to argue in several
earlier posts.
Earlier (Section 9.3.1), it was noted that the
climate response varies from
model to
model even when the radiative forcing
used to drive the
models is similar.
Recent work in
modelling the warm
climates of the
Early Eocene shows that it is possible to obtain a reasonable global match between
model surface temperature and proxy reconstructions, but only by
using extremely high atmospheric CO2 concentrations or more modest CO2 levels complemented by a reduction in global cloud albedo.
Climatic implications of

use and the reliability of LES, the application of nonlinear time series analysis on flow fields, and the inclusion of marine organic aerosol sources in global
