On July 7, 2026, the United Nations published a report titled "Leveraging AI to enhance multi-hazard early warning systems," and Google on the same day outlined three ways its AI technologies and products are helping governments and international organizations prepare for and respond to natural disasters.
July 7, 2026 · Google × UN Early Warnings for All
AI Flood Forecasting for the Whole Planet
Google is backing the UN-led drive to protect everyone on Earth with multi-hazard early warnings by 2027 — pairing machine-learning river models with Gemini-built flash-flood data to reach data-sparse regions no sensor network covers.

Each block ≈ 1 day. River forecasts stretch a week ahead; fast, localized flash floods resolve to a single day.
FLOOD HUB
Riverine flood forecasting
Water-level trends, inundation maps & daily real-time forecasts — up to 7 days ahead, free to share.
GROUNDSOURCE
Gemini turns news into data
~2.6M events across 150+ countries and 20 years — works even where no sensors exist.
CRISIS RESPONSE
AI damage assessment
Satellite imagery analyzed by AI to speed post-disaster response and resilience.
~30%
cut in medical costs found in an early-warning study
Warnings translate into real savings.
Across 319 communities and 1.8 million people in Bihar, India, timely flood warnings were linked to roughly a third lower medical costs.
Promise
Forecasts work in data-poor regions
Operates without ground sensors
Reaches billions via Search, Maps & Flood Hub
Limits
Resolves to city scale, not block level
Limited detail on severity & flood depth
Flash-flood forecasting still early stage

Global rollout · 2027 goal
As of 2025, 119 countries have multi-hazard early warning systems — a sharp rise since 2015 — though coverage remains low among least developed countries and small island developing states.
