To reach their conclusions, the researchers analyzed nearly 30 years of observational temperature and precipitation data and also
used computer model simulations that considered soil, atmospheric, and oceanic conditions and projected changes in greenhouse gases.
Jacobson's research, detailed in a paper published July 30 in the Journal of Geophysical Research: Atmospheres, is based on a three -
dimensional computer model simulation of the impacts of biomass burning.
Jacobson's research, out this week in the Journal of Geophysical Research: Atmospheres, is based on 3 -
D computer model simulations of the impacts of biomass burning.
This is the first of two pieces on the recent IPCC workshop in Hawaii, This brought together independent researchers from all over the world to
analyse computer model simulations of the last 150 years and to assess whether they are actually any good.
Computer model simulations tend to capture the slow rate of warming in the western Pacific over the last few decades, but they show the warm pool heating rapidly in the future.
It is now known that the observed pattern of tropospheric warming and stratospheric cooling over the past 30 to 40 years is broadly consistent
with computer model simulations that include increases in CO2 and decreases in stratospheric ozone, each caused by human activities.
Liang and Strahan based their analysis on a combination of
computer model simulations of the atmosphere and measurements of the concentrations of the ozone - depleting chemicals.
Computer model simulations have suggested that ice - sheet melting through warm water incursions could initiate a collapse of the WAIS within the next few centuries, raising global sea - level by up to 3.5 metres.»
The reflected sunlight also hits more of the soot and other pollutants commonly found in the atmosphere above cities, which also increases warming, according to
the computer model simulation.
The above two charts provide further proof that
computer model simulations were spectacularly wrong.
It might be very useful to run
a computer model simulation in which the ENSO is constrained to follow its known historical behavior, so we can see how it might have affected actual history rather than a gereric «earth system.»
The hypothesis and
the computer model simulation used to predict global climate has consistently failed.
The researchers also found another vital factor in
their computer model simulations.
We think, based on basic physics and
computer model simulations, that this can induce ocean currents that transport heat laterally and thereby affect climate.
