"A day after a once-in-a-thousand-year rainstorm, southern Appalachia
faces Hurricane Helene
Helene could dump 6 to 12 more inches of rain in areas that have just
recently been deluged. "

More frequent once a thousand year rainstorm is supposed to be cause by
global warming.

Question:
Would global warming bring more or less water/ice to the Himalayas
region?

The following from Microsoft Copilot:

"The relationship between higher temperatures and increased moisture in
the atmosphere is well-documented. For every 1°C increase in
temperature, the atmosphere can hold about 7% more moisture, according
to the Clausius-Clapeyron equation. This increase in moisture can lead
to more intense and frequent precipitation events.

However, breaking down the statistical contribution of higher
temperatures and increased moisture to precipitation patterns involves
complex climate models and data analysis. Studies have shown that:

Increased Moisture: Higher temperatures lead to more evaporation
and, consequently, more moisture in the atmosphere. This additional
moisture can result in heavier rainfall when conditions are right for
precipitation.

Temperature Effects: Warmer temperatures can also influence
atmospheric circulation patterns, potentially leading to more intense
storms and altered precipitation patterns.

Combined Impact: The combination of higher temperatures and
increased moisture can amplify the intensity and frequency of extreme
weather events, including heavy rainfall and storms.

While specific statistical breakdowns can vary depending on the region
and the specific climate model used, the general consensus is that both
factors significantly contribute to changes in precipitation patterns."
