The IPCC Fourth Assessment

The IPCC Fourth Assessment Report and the fiftieth anniversary of Sputnik.

Much has been made of the idea of consensus in the development of the IPCC's role since it was set up in 1988 by WMO, the World Meteorological Oganisation, and UNEP, the United Nations Environment Progamme. The IPCC's scientific assessment involves studying the output from various climate models as well as various historical records of atmospheric and marine data. It is well known that the chao...

Tropical Cyclones and Global Climate Change: A Post-IPCC Assessment

The very limited instrumental record makes extensive analyses of the natural variability of global tropical cyclone activities difficult in most of the tropical cyclone basins. However, in the two regions where reasonably reliable records exist (the North Atlantic and the western North Pacific), substantial multidecadal variability (particularly for intense Atlantic hurricanes) is found, but th...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Radiative forcing by well-mixed greenhouse gases: Estimates from climate models in the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4)

[1] The radiative effects from increased concentrations of well-mixed greenhouse gases (WMGHGs) represent the most significant and best understood anthropogenic forcing of the climate system. The most comprehensive tools for simulating past and future climates influenced by WMGHGs are fully coupled atmosphere-ocean general circulation models (AOGCMs). Because of the importance of WMGHGs as forc...
