Professor Dan Lunt, from the School of Geographical Sciences and Cabot Institute at the University of Bristol said: «Because
climate models are based on fundamental scientific processes, they are able not only to simulate the
climate of the
modern Earth, but can also be easily adapted to simulate any planet, real or imagined, so long
as the underlying continental positions and heights, and ocean depths are known.»
«
As Earth continues to warm, it may be approaching a critical
climate threshold beyond which rapid and potentially permanent — at least on a human time - scale — changes not anticipated by
climate models tuned to
modern conditions may occur,» the report says.

I can read any peer - reviewed article I like on
modern climate models, but until I go through much of the process of building, running, validation, discussing with colleagues how they solved particular wrinkles etc of some
models, I am unlikely to fully comprehend
climate modelling as a skilled craft.

climate models forced with greenhouse gas levels
as high
as modern ones tend to result in Pliocene - like
climate (~ 3 million years ago) when sea levels were estimated to be 14 meters higher than they are today.
Our RAV4 was a top - tier Limited
model that goes beyond the entry LE trim with interior enhancements such

climate controls, autodimming rearview mirror, heated front bucket seats, and SofTex trim for all seats and door trim — SofTex being a nice and
modern way of saying leatherette.

The papers questioned everything from the relative role of natural mechanisms in changes to the
climate system vis - à - vis increased CO2 concentrations, the allegedly «unprecedented» nature of
modern climate phenomena such
as warming, sea levels, glacier and sea ice retreat, and the efficacy and reliability of computer
climate models for projecting future
climate states.
As we have seen, there are bad
climate scientists who rig the computer
models representing a huge rise in the Earth's overall average temperature and there are good
climate scientists who have waged a long and increasingly successful effort to debunk the greatest hoax of the
modern era.
In addition to running
climate models, the researchers compared
modern warming to similar temperature increases that happened approximately 120,000 years ago in a period known
as the Eemian, when global sea level was 5 to 9 meters (between 16 and 30 feet) higher than it is today due to the release of glacial water.
Above all, these supposed
modeling experts and
climate scientists need to terminate their biases and their evangelism of political agendas that seek to slash fossil fuel use, «transform» our energy and economic systems, reduce our standards of living, and «permit» African and other impoverished nations to enter the
modern era only in a «sustainable manner,»
as callous elitists often insist.
These records can then be integrated with observations of Earth's
modern climate and placed into a computer
model to infer past
as well
as predict future
climate.
As emphasized by the Intergovernmental Panel on
Climate Change (IPCC),
modern models faithfully simulate continental to global scale temperature patterns and trends observed during the 20th century.
We are so quick
as scientists, non experts, the lay public, some ill informed undergrads, ad infinitum, to argue in this blog, however, you
as a first hand expert
modeling paleoclimate and
modern climate trends and obviously with a handle on chemistry and physics, also have a vested interest in our planet and though you do the
modeling for a living, I do not doubt it has helped you gain inisghts and opened up your eyes to the complexity and current to future detriments and potentialities we all face
as humanity.
The injection of stratospheric aerosols from the eruption of Mt. Pinatubo was noted
as the first
modern test of a known radiative forcing, and indeed one
climate model accurately predicted the temperature response (Hansen et al., 1992).
Within a
modern complex
climate model, forcings other than solar are not imposed
as energy flux perturbations.
«It is unlikely that coastal cities or low - lying areas such
