predicted by current climate models in response to a global perturbation in the radiative energy balance.»

by anthropogenic greenhouse gases while maintaining nearly constant relative humidity.
Indeed, though the
current pattern of winter U.S. warmth looks much more like the pattern
predicted by climate models as a response to anthropogenic forcing (see Figure below left) than the typical «El Nino» pattern, neither can one attribute this warmth to anthropogenic forcing.
Kevin Hamilton, who co-authored the report, warns: «If our
model results prove to be representative of the real global
climate, then
climate is actually more sensitive to perturbations
by greenhouse gases than
current global
models predict, and even the highest warming predictions would underestimate the real change we could see.»

climate models predict that Arctic sea ice will decline in response to greenhouse gas increases, the
current pace of retreat at the end of the melt season is exceeding the
models» forecasts
by around a factor of 3 (Stroeve 2007).
This colorful and elegant species, formerly called Louisiana Heron, is common in marshes along much of the East Coast of the U.S. Audubon's
climate model predicts a 54 percent loss of
current summer range
by 2080, with some potential expansion well into the interior, particularly in the Mississippi Valley, an area well known for hosting wandering Tricolored Herons in late summer.
The report,
by University of Alabama scientist Roy Spencer and published in the peer - reviewed journal Remote Sensing, argues that heat is actually escaping from Earth much more quickly than
current climate models predicted.
My Reply - Even IF the
climate model could
predict the
current statistics of the occurrence of ENSO, the NAO, the PDO, etc [which is proving quite a daunting challenge], this,
by itself is not sufficient to justify their use to provide projection of CHANGES in the statistics of ENSO, the NAO, the PDO, etc events in the coming decades.
A significant and serious concern among mainstream
climate scientists in this regard is the inability of the
models to
predict climate surprises, that is, rapid non-linear changes in the
climate system that have happened in the historical
climate record and that may be triggered
by current human activities.
Since the only
climate crisis is a
predicted one, and the
current models have no predictive skill (either theoretically,
by the above argument, or demonstrated), there is no crisis and the
current alarmism is bogus.
and of course «If the role of internal variability in the
climate system is as large as this analysis would seem to suggest, warming over the 21st century may well be larger than that
predicted by the
current generation of
models, given the propensity of those
models to underestimate
climate internal variability»
These activities can be grouped under the following areas: improve our knowledge of Earth's past and present
climate variability and change; improve our understanding of natural and human forces of
climate change; improve our capability to
model and
predict future conditions and impacts; assess the Nation's vulnerability to
current and anticipated impacts of
climate change; and improve the Nation's ability to respond to
climate change
by providing
climate information and decision support tools that are useful to policy makers and the general public.»
But a growing body of scientific evidence suggests that the projections of
climate change that have been made
by the
current family of computerized
climate models has been overdone — that the world will warm up significantly less than has been
predicted as a result of our ongoing carbon dioxide emissions.
If the role of internal variability in the
climate system is as large as this analysis would seem to suggest, warming over the 21st century may well be larger than that
predicted by the
current generation of
models, given the propensity of those
models to underestimate
climate internal variability.
If the role of internal variability in the

(b) Admitted
by all: no
current climate models can
predict natural variation.
Audubon's
climate model projects a 99 percent loss of
current winter range
by 2080,
predicting climate suitable areas diffusing northward.
Audubon's
climate model projects a 66 percent loss of
current winter range
by 2080, with a significant amount of potential expansion
predicted.
Perhaps, a new kind of
climate models based, at least in part, on empirical reconstruction of the
climate constructed on empirically detected natural cycles may indeed perform better, may have better
predicting capabilities and, consequently, may be found to be more beneficial to the society than the
current GCMs adopted
by the IPCC.
If coal - to - liquids fuels replace oil global temperatures will rise a critical 2Â °C
by 2042, three years earlier than
current climate models predict.

by the IPCC are unreliable for
predicting future
climate.»
