Is global warming causing a low water crisis on the upper reaches of the Yellow River? — Global warming is usually accompanied by an increase in precipitation, but the upper Yellow River region has not been very fortunate in this respect. — In the next few decades, if air temperature rises 3¬∞C and precipitation drops 20%, then the amount of water in the upper reaches of the Yellow River will decrease 50% or more from the present level, warned experts in hydrology and climate from Lanzhou in the most recent edition of the Journal of Glaciology and Geocryology [Bingchuan Dongtu].
