A thesis of the UGR analyses more than 20-million-year-old vegetation to study climatic evolution

This release is also available in Spanish.

The characteristics of the vegetation that inhabited Earth 21 million years ago can be vital to get to know climatic evolution in the last million years and the causes for these changes. A thesis of the University of Granada (Universidad de Granada [http://www.ugr.es]) has analysed samples of the sedimentary bowls of the geographic section from the south of Spain to Turkey to check that 14 million years ago there were glaciations in the south pole that changed the ruling subtropical climate into warm and transformed the characteristic vegetation of this area. A result that can be "vitally important to determine if the present climatic change is due to a natural period or, on the contrary, it is a consequence of the bad management of man", according to the author of the work, Gonzalo Jimnez Moreno.

Although the project has been focused on the palynological study of numerous localities of the Miocene, the conclusions obtained suggest that the cooling experienced in the planet 14 million years ago also extended to Upper Miocene, Pliocene and Pleistocene, with the respective change in the climate and the vegetation.

Pollen analysis

From the remains of pollen it has also been possible to characterize a climatic latitudinal gradient in the southwest of Europe and climatic changes with regard to Milankovitch cycles (the Serbian astrophysicist Milutin Milankotovitch who devoted his career to develop a mathematical theory of climate in which he established, among other results, that changes in the seasonal distribution of sunshine, due to astronomical factors, are the responsible for the expansion and retreat of the big glacial layers). In addition, the scientist of the UGR [http://www.ugr.es] points out that another reason for the drop in
