The Big Picture

Warming is intensifying swings between drought, heavy rainfall, floods, severe storms, snowpack loss, water scarcity, and wildfire conditions. The enduring issue is how societies manage water and disaster risk when historical precipitation patterns no longer provide reliable planning assumptions.

Hydroclimate volatility affects drinking water, agriculture, hydropower, flood protection, wildfire preparedness, insurance, urban planning, and interstate or international water governance. It is likely to remain a central adaptation challenge across regions.
