Updated Trewartha climate classification with four climate change scenarios

The Updated Trewartha climate classification (TWCC) at global level shows the changes that are expected as a consequence of temperature increase and imbalance precipitation. This type is more precise than Köppen classification. Predictions included in (T °C) change amount precipitation (PA mm). Two models MIROC6 IPSL-CM6A- LR were used, along with 4261 meteorological stations from which data on taken. These used because they represent most extreme CMIP6 database. Four scenarios their territories analysed accordance TWCC representative concentration pathway (RCP) by 2.6, 4.5, 6.0 8.5 W/m2 follow between 0.3°C 4.3°C relation to being for periods 2021–2040, 2041–2060, 2061–2080 2081–2100. biggest extremes shown last grid period 2081–2100, reflecting T up 4.3°C. With help GIS (geographical information systems) spatial analyses, it possible estimate zones well movement. Australia South East Asia will suffer biomes, followed America North America. Climate belts undergo due such according Ar, Am, Aw BS, BW, E, Ft Fi. Antarctic lose 11.5% territory under Fi climates within 2081 2100. conclusion Bwh Bwk, deserts, 119.8%
