Perhaps rivers could see a net increase in volume globally? After all, a stream is simply the release of sun energy that moved the water to a higher potential energy in the first place.
That was my impression of the Grand Canyon. After having spent a week in Bryce and Zion, the Grand Canyon was a bit of a let down. Zion frames in the smaller features to give everything perspective, whereas the Grand Canyon was too expansive to be be amazed by it's much larger size. Then again, I didn't hike into the canyon or anything, so that probably makes a big difference.

I believe that,the Ganges,Yellow,and Mekong rivers all originate from time-release,mountain glaciers,and will all vanish,along with those who rely on them for year-round water supply.And we know from archeology that,all civilizations who rely on irrigation perish.It's cyclical.Albeit on large timescales,which are no longer valid as the planet warms,non-linearly.
South America has already lost some of their Andes Mountains hydro resources.As tropical mountain ice caps are the first to go.And are.
