In Hungary, the Great Plain and the western part of Transdanubia had different geomorphological and climatic characteristics during the Late Glacial, the Holocene and the present day. As a result, the vegetation in the two areas was also different, as indicated by palynological data. In Late Glacial times the Great Plain had an extremely continental climate whereas the western part of Transdanubia had a somewhat milder one. This clear distinction can be made on the basis of pollen spectra between the palaeo-vegetation of Transdanubia and that of the Great Plain.
A comparison of the pollen data, and the climatic changes indicated by the carbonate content, and δ18OPDB and δ13CPDB isotope ratios of the sediments of Lake Balaton, have shown that these data can be correlated beginning from the B611ing, the onset of permanent water coverage.
Figures & Tables
The climate of the early Earth was probably very warm and has, in general, reduced since the Archean. However, it now seems that the world is about 0.6°C warmer than it was 100 years ago and estimates of the rate of global warming over the next century range from 0.16°C to 0.35°C per decade. Concurrently, global sea-level is predicted to rise from 2.4 to 10 cm per decade. These rates of change are much faster than those normally associated with the geological record, causing geologists and palaeontologists to reassess their data and their forecasts on rates of future change.
With the current interest in global climatic change and, more specifically, with global warming, it is clear that palaeontologists have valuable information to provide on the impacts of past climatic change. This volume contains papers from an international array of such geologists and palaeontologists, showing how studies of micro- and macrofossils, plant and vertebrate fossils from a range of geological ages have contributed to our understanding of how climate affects both local and more widespread areas. The contributions are arranged in geological order, ranging from the Permo-Carboniferous to the post-glacial recovery of the last 18,000 years, with an emphasis on climate change during the last two million years, particularly in NW Europe.
Climates: Past and Present will be of interest to palaeontologists, geologists and palaeoclimatologists who specialize in climatic reconstructions and any professionals enagaged in research into the geological aspects of climate change.
