Microfossils unravel climate history of tropical Africa
...re difference with existing records of continental rainfall variability, lead author Johan Weijers and his colleagues concluded that the land-sea temperature difference has by far the largest influence on continental rainfall. This can be explained by the strong relationship of air pressure to temperature. Wh...Global 'sunscreen' has likely thinned, report NASA scientists
...ycle of evaporation, more cloud formation and more rainfall ?has not yet been observed. "Less sunlight reaching the surface counteracts the effect of warmer air temperatures, so evaporation does not change very much," said Gavin Schmidt of GISS, a co-author of the paper. "Increased aerosols probably slowed th...Scientists: As rainfall changes, tropical plants may acclimate
