WATER RESERVES IN SOILS AS AFFECTED BY GLOBAL CLIMATIC WARMING - EXAMPLE FORECAST FOR EASTERN-EUROPE

With the awaited global warming by 1 degrees C, the same water reserve s in spring will be proper to tundra, podzolic, sod-podzolic, gray for est soils and chernozems. They will be higher by 100-150 mm in chestnu t, cinnamonic, and brown semidesertic soils. The maximum summer drying is thought to result in a decrease of water reserves by 30-50 mm in t undra soils and by 50-80 mm in taiga ones. There will be no changes in steppe zone while, in dry-steppe, water reserves will increase by 20- 60 mm. If the mean global temperature rises by 2 degrees C, water rese rves will be the same as in the previous case in spring, whereas a dec rease by 40-60 mm in summer is probable for sod-podzolic soils and an increase by 50-60 mm may be expected in the dry-steppe zone.
