As for precipitation, [Moelg and Hardy, 2004] tentatively conclude that the glacier might be in positive mass balance if snowfall were increased to its 1880 maximum rate, even if temperature is held fixed at its present value.

Could, for example, their share of global precipitation be increasing relative to the area in the broad temperate / tropic belt?

If tropical glaciers continue to retreat despite an increase in precipitation, that will constitute a powerful case for the role of air temperature.

In Relationships between Water Vapor Path and Precipitation over the Tropical Oceans, Bretherton et al showed that although the Western Pacific warmer surface waters increased the water in the atmosphere compared to the Eastern Pacific, rainfall was lower in the Western Pacific compared to the Eastern Pacific for equal amounts of water vapor in the atmospheric column — e.g., about 10mm / day in the Western Pacific, versus ~ 20mm / day in the Eastern Pacific at 55 mm water vapor, the peak of the distribution of water vapor amounts.

Indeed, snowfall is often predicted to increase in many regions in response to anthropogenic climate change, since warmer air, all other things being equal, holds more moisture, and therefore, the potential for greater amounts of precipitation whatever form that precipitation takes.

Global models that combine precipitation, temperature, and CO2 effects for the A2 scenario generally show reduced yields in the tropics and increased yields in temperate zones (26).

Given that atmospheric water - holding capacity is expected to increase roughly exponentially with temperature — and that atmospheric water content is increasing in accord with this theoretical expectation (6 — 11)-- it has been suggested that human influenced global warming may be partly responsible for increases in heavy precipitation (3,5,7).

So: The study finds a fingerprint of anthropogenic influences on large scale increase in precipitation extremes, with remaining uncertainties — namely that there is still a possibility that the widespread increase in heavy precipitation could be due to an unusual event of natural variability.The intensification of extreme rainfall is expected with warming, and there is a clear physical mechanism for it, but it is never possible to completely separate a signal of external forcing from climate variability — the separation will always be statistical in nature.
