Stephen Green, environmental coordinator at Ringmer Community College, and one of the mentors for the Ashden LESS
CO2 programme says that «most of the staff at our college are degree educated professionals — they are more
than capable of turning their
computers off at the end of the day.
When the reseachers at the Center for International Climate and Environmental Research — Oslo (CICERO) applied their
computer «model and statistics to analyse temperature readings from the air and ocean for the period ending in 2000, they found that climate sensitivity to a doubling of atmospheric
CO2 concentration will most likely be 3.7 °C, which is somewhat higher
than the IPCC prognosis.»
«It is undeniably true that global temperature increases have been far, far less
than doomsday
computer models predicted — about three times smaller, and there are good reasons to suspect the increases from further human
CO2 emissions would be smaller still, without imposing draconian regulations.
Results from an irreducibly simple climate model,» concluded that, once discrepancies in IPCC
computer models are taken into account, the impact of
CO2 - driven manmade global warming over the next century (and beyond) is likely to be «no more
than one - third to one - half of the IPCC's current projections» — that is, just 1 - 2 degrees C (2 - 4 deg F) by 2100!
The scientific paper, entitled «Why Models Run Hot,» concludes that the
computer models overstated the impact of
CO2 on the climate: «The impact of anthropogenic global warming over the next century... may be no more
than one - third to one - half of IPCC's current projections.»
The lack of warming for more
than a decade — indeed, the smaller -
than - predicted warming over the 22 years since the UN's Intergovernmental Panel on Climate Change (IPCC) began issuing projections — suggests that
computer models have greatly exaggerated how much warming additional
CO2 can cause.
Yet I've often heard that the H2O only appears in the
computer models as being forced by
CO2, and therefore it doesn't matter that H2O is a far more effective greenhouse gas
than CO2.
For example, the
computers themselves don't somehow decide if
CO2 is a more important forcing on the climate
than solar activity — the modelers, by the assumptions the feed into the model, decide these things.
