“…The limestone pavements of the Burren cannot be fully discussed without some reference to the grikes (kluftkarren) (Gams, 1973(Gams, , 1978Bonacci, 2004), Turlough (Sheehy Skeffington et al, 2006) Doline (Sauro, 2003;Ford and Williams, 2007), Limestone pavement (Williams, 1966;Zseni et al, 2003), Schichttreppenkarst (Bögli, 1980) Meso (c.1 cm-10 m) Karren Rinnenkarren (Bögli, 1976;Veress, 2009a), Kluftkarren (Williams, 1966;Goldie, 2009), Flachkarren (Williams, 1966;Goldie, 2009), Meanderkarren (Veress, 2000(Veress, , 2009b Kamenitze (Bögli, 1960, Cucchi, 2009Eren and Hatipoglu-Bagci, 2010), Rillenkarren (Vincent, 1996;Glew and Ford, 1980;Lundberg and Ginés, 2009), Rundkarren (Zseni, 2009) Micro (c. 1 mm-1 cm) Microkarren Microrills (Ford and Lundberg, 1987;Gómez-Pujol and Fornós, 2009a;Grimes, 2007), Rillensteine (Laudermilk and Woodford, 1932), Micropits (Ginés and Ludberg, 2009 and clints (flachkarren) that develop on their surface. Ford and Williams (2007) classify these features as fracture controlled linear forms and highlight the relationship of grikes to major joints in the limestone as well as bedding planes.…”

The term glaciokarst describes a landscape where both glacial and karstic processes have contributed to geomorphological evolution and has been applied to a range of environments from the high arctic to the alpine Mediterranean. Nevertheless, glaciokarstic environments globally often exhibit significant variation in geomorphological processes and landforms due to these geographical differences. The Burren, County Clare, Republic of Ireland, is often quoted as a quintessential glaciokarstic landscape. However, the Burren and other similar environments would appear to lean towards one end of the glaciokarst spectrum, where solutional and biological processes have been dominant throughout the Holocene, in contrast to ice-dominated glaciokarsts where karstic and biokarstic processes are temperature-limited and cryospheric processes remain the principal geomorphological agents.Holocene landscape evolution and the development of a range of meso-, micro-and nano-scale karren features on limestone surfaces appears to be largely biokarstic in origin. Karstification of many glacially scoured limestone pavements would have begun under acidic soil cover, with biological soil processes contributing to smooth, rounded cryptokarstic surface forms. Holocene soil erosion is attributed to anthropogenic activity, climatic fluctuations and the evolution of the karstic groundwater system leading to vertical soil loss through widening grikes. Exposed limestone pavements subject to subaerial conditions often exhibit extensive lichen colonization which has been shown to influence the overall rate of karstification and contribute to the development of micro-and meso-scale bioweathering features. Where cryptokarstic features have been exhumed from beneath soil cover, their evolution under subaerial conditions leads to intermediate, polygenetic karren features.In light of our current understanding of the Burren landscape, it is proposed that the term glaciobiokarstic may be a better expression to encompass the biological processes that have played a fundamental role in the evolution of the Burren and similar landscapes, without neglecting the contribution of glacial and inorganic karstic processes.

In this study the changes in the nighttime heat load in Carpathian Basin cities during the 21st century were examined. To quantify the heat load, the tropical night climate index was used. The MUKLIMO_3 local scale climate model was used to describe the urban processes and the land use classes were defined by the local climate zones. The expected change was examined over three periods: the 1981–2010 was taken as reference period using the Carpatclim database and the 2021–2050 and 2071–2100 future periods using EURO-CORDEX regional model simulation data for two scenarios (RCP4.5 and RCP8.5). To combine the detailed spatial resolution and the long time series, a downscaling method was applied. Our results show that spectacular changes could be in the number of tropical nights during the 21st century and the increasing effect of the urban landform is obvious. In the near future, a slight increase can be expected in the number of tropical nights, which magnitude varies from city to city and there is no major difference between the scenarios. However, at the end of the century the results of the two scenarios differ: the values can be 15-25 nights in case of RCP4.5 and 30-50 nights in case of RCP8.5. The results show that dwellers could be exposed to high heat load in the future, as the combined effect of climate change and urban climate, thus developing various mitigation and adaptation strategies is crucial.
