The increasing frequency of mass coral bleaching and associated mortality threaten the future warmwater reefs. Although thermal stress is widely recognized as main driver bleaching, exposure to light also plays a central role. Future projections impacts climate change on reefs have date focused temperature not considered role clouds in attenuating response corals. In this study, we develop temp...

Clement et al. (Reports, 24 July 2009, p. 460) provided observational evidence for systematic relationships between variations in marine low cloudiness and other climatic variables and found that most current-generation climate models were deficient in reproducing such relationships. Our analysis of one of these models (GFDL CM2.1), using more complete model output, indicates better agreement w...

For developing countries like Pakistan, the paucity of reliable solar radiation data necessitates the development of empirical models. To develop such a model one could use various parameters. In this study, linear regression models are developed to estimate the monthly average daily global radiation using cloudiness data for Karachi, Pakistan for the period of 20 years (1990-2010). The results...
