Abstract: Projections of future warming in the Intergovernmental Panel on Climate Change (IPCC) Third Assessment Report (TAR) are substantially larger than those in the Second Assessment Report (SAR). The reasons for these differences ...

Abstract: A new compilation of monthly mean surface air temperature data for the Southern Hemisphere for 1851?1984 is presented based on land-based meteorological station data. Where possible, the station data used in the analysis ...

Abstract: A probability distribution for values of the effective climate sensitivity, with a lower bound of 1.6 K (5th percentile), is obtained on the basis of the increase in ocean heat content in recent decades from analyses of ...

Abstract: A new compilation of monthly mean surface air temperature for the Northern Hemisphere for 1851?1984 is presented based on land-based meteorological station data and fixed-position weather ship data. This compilation differs ...

Abstract: Antarctic temperature variations for 1957°82 have been objectively analyzed by gridding monthly data, from 16 stations, onto a 5° latitude by 10° longitude grid, from 65 to 90°S. These gridded data were used to calculate ...

Abstract: Quantification of the uncertainties in future climate projections is crucial for the implementation of climate policies. Here a review of projections of global temperature change over the twenty-first century is provided ...
