If there is a difference, has this been factored in when discussing the effect of melting ice sheets?By email, no name or address supplied

Ice sums

New Scientist has reported that the rivers in the Himalayas will be starved of water when the glaciers disappear. If the glaciers are neither shrinking nor growing, the amount of water fed into the rivers from the Himalayan glaciers in a year should presumably be approximately equal to precipitation in the Himalayas over the same period. Assuming that rainfall remains about the same after the glaciers disappear, why shouldnâ€™t the rivers still receive the same amount of water?Felix Lim, South Australia
