FŰKÖH, L.: Holocene climate changes as model of global climate change
and the latter disappear from the fauna of the Carpathian-basin. Bogs silt up, the anthropogenous influence is getting stronger what is proved by archaeological data. The vegetation of medium high mountain ranges refers to warning up and increase in precipitation. Nowdays we can observe a climate change again. Its result in the decrease of precipitation in the Carpathian basin. There are two seasons only instead of four. Signs of desertification can be observed at the central part of the basin. If we accept the cyclicity which is based on the above mentioned malacological material but also proved vertebrate paleontological and palynological data (Kordos, L.; Kretzoi, M.; Zólyomi, B.; Járai Komlódi, M.) and do not take into consideration those smaller climate changes which were pointed out by Kordos with the help of "vole thermometer" between 4000-O B.P. at the northern-hemisphere (Kordos, L. 1977), we can conclude on that 2000 years cycles can be observed in the climate changes of the last thousand years (changing kontinental and atlantic climate phases) (1. fig.). Recent climate changes can be interpreted on the basis of this theory, but that fact also have to be taken into consideration that this natural process can be influenced by anthropogenous effects.
