Characterized by high atmospheric carbon dioxide and global warmth, the Cretaceous era is very relevant to future climatic change studies...read more (view table of contents, read Amazon.com's description)

Product Description: Computer Climate Models are essential tools for understanding environmental change but the results of modelling exercises are seldom accessible to the wider community of teachers and researchers on their desktop machines. This CD ROM presents the results of a series of simulations of global climate for the Carboniferous (300Ma) through the Mesozoic (150, 95 and 70Ma), Tertiary (55 and 15Ma) and Quaternary (115, 21 and 6 Ka) to Present Day and enhanced greenhouse effect simulations (2 x CO2) for surface temperature, soil moisture, precipitation, cloud cover, surface pressure, wind strengths, storminess, and snow depth in up to three projection modes: Rectilinear, Mollweide and Polar...read more

Product Description: Plant fossils, which provide valuable data for many fields, are usually only poorly preserved and fragmentary remains of the original organism. Their identification is difficult, and their study bedevilled by problems of taxomony and classification never encountered with living plants...read more
