Keeping the Sun in proportion
Article Abstract:
Climatic models devised by two sets of researchers failed to confirm the theory that fluctuations by the Sun rather than anthropocentric greenhouse gases caused global-mean surface air temperatures to go up by 0.8 degrees Celsius between 1880 and 1990. P.M. Kelly and T.M.L. Wigley constructed an energy-balance model for global temperature changes between 1765 and 1985, while Michael E. Schlesinger and Navin Ramankutty examined a climate-ocean model for the 1638-1985 era. Both groups conclude that greenhouse gases are the principal but not the only factor behind global warming.

Aluminium and global warming
Article Abstract:
Aluminum smelting is a significant anthropogenic source of two greenhouse gases, the chlorofluorocarbons CF4 and C2F6. The gases' high estimated global warming potential and the likelihood that they will persist in the atmosphere for over 10,000 years make them an important cause of greenhouse warming. Aluminum production does far more to exacerbate global warming than cement production, which is the only non-fossil fuel source of greenhouse gases commonly recognized.

Large-scale warming is not urban
Article Abstract:
An analysis is conducted to determine if dis a consequence of urban development and to show that globally, temperatures over land have risen as much on windy nights as on calm nights. The analysis demonstrates that urban warming has not introduced significant biases into estimates of global warming.
