MAGICC climate model simulator (MAGICC: Model for the Assessment of Greenhouse-gas Induced Climate Change). MAGICC was developed by scientists at the National Center for Atmospheric Research under funding by the U.S. Environmental Protection Agency.
The temperature savings are presented to three significant digits in order to tell the results apart. In the real world, the impacts from the emissions reduction pathways are not nearly so precise and, in fact, the temperature savings from most of the different carbon dioxide emissions reduction pathways are scientifically impossible to tell apart from each other, and in many cases, are impossible to tell apart from the original A1B scenario, i.e., they are the same thing as doing nothing.
Geologist Dr. Robert Giegengack - Former chair of Department of Earth and Environmental Science at the University of Pennsylvania:
Giegengack laments "the enormity of the hubris that leads us to believe that we can 'control' climate by controlling anthropogenic emission of CO2."
"If anthropogenic CO2 is contributing to climate warming now under way, nothing we are doing, or contemplating doing, can have any measurable effect on that warming."
Global Warming/Climate Change has evolved into "a semi-religious campaign advanced by well-intended people who feel, deep in their hearts, that they are 'saving the planet.'"
"It beggars the imagination to assert that the natural factors that drove the warming trend from 18,000 years ago to ~300 years ago (with some unexplained temperature reversals) abruptly stopped operating at the end of the Little Ice Age to accommodate our political need to attribute climate variability to human industrial activity."
"Today’s climate is close to the coolest it has been in 540,000,000 years, and the atmospheric concentration of CO2 is close to the lowest it has been."
"Climate models are instructive, but they lead to scenarios, not predictions. They can be manipulated to yield desired outputs."
