ARE THE IPCC CARBON EMISSION AND CARBON DIOXIDE STABILIZATION SCENARIOS REALISTIC?

The widely accepted presumption that additional cumulative atmospheric carbon emissions will more than double or triple the pre-industrial carbon dioxide concentration by the year 2100 is questioned. This buildup is unlikely because of deficiencies in the scenarios for global climate change ascribed to anthropogenic greenhouse gas emissions currently used by th UN Intergovernmental Panel on Climate Change (IPCC). These deficiencies are reflected in inadequate recognition of the emergence of natural gas as the transition fuel to a sustainable energy future and in the ability of terrestrial biomass to sequester more anthropogenic C emissions than suggested by IPCC global C budget models.
