Global warming melts snow slowly, lessens water on earth
Q. Scientists have said global warming could melt mountain snow slowly, leading to which of the following effects?- Published on 01 Mar 17a. Less water for humans
b. More water for plants
c. Water that evaporates more easily rather than flowing into reservoirs
d. All of the above
ANSWER: All of the above
Researchers indicated global warming could melt mountain snow slowly, this may be a bad news for American West.
Scientists have known that snow is starting to melt sooner as the climate warms. The research found early snowmelt is slower than in the summer, mostly because the sun is weaker and nights are cooler in winter's latter part and early spring.
Slower snowmelt could mean less water for humans. Snowmelt lingers in the soil and is taken up by plants or evaporates instead of flowing into reservoirs.
This finding could explain the reason computer models show snow-fed rivers expected to lower as the climate warms.
