As the United States passes a tipping point in water security 💧, new research reveals that millions of Americans now face a growing crisis in accessing clean, affordable water 🚰. The study demands that policies treat water as a basic human need 🌍 and that they prioritize the needs of those most affected.

💧 Nobel laureate Prof. Omar Yaghi's invention uses reticular chemistry to create materials that extract moisture from the air, providing clean water even in arid conditions. Atoco's units, shipping container-sized and powered by low-grade thermal energy, can produce up to 1,000 liters daily, offering a crucial solution for islands vulnerable to hurricanes and drought, like those in the Caribbean.

💨 The technology is presented as a climate-friendly alternative to desalination, addressing concerns about brine release. Yaghi, a 2025 Nobel Prize winner in Chemistry, highlighted its potential to assist communities impacted by hurricanes like Beryl and Melissa, which have left thousands without water.

🌍 The UN reports that nearly three-quarters of the world's population lives in water-insecure countries. Yaghi's invention offers hope, particularly for places like Grenada, Carriacou, and Petite Martinique, which face frequent hurricanes and intensifying droughts.

Over half of the world's reservoirs will be "functionally dead"—more than 50% full of dirt—by 2060 due to sediment build-up, a new study predicts. Analyzing 550,000+ dams, researchers found we lose 7% of freshwater storage capacity per decade, threatening water supplies for 2 billion people.

💧 **Brazil's Water Disasters: 1991-2024 Overview**
* Nearly 60,000 water-related disasters (WRDs), including floods, storms, landslides, and droughts, were recorded in Brazil between 1991 and 2024. These events resulted in at least 4,774 deaths, 3,031 missing persons, over 129 million affected individuals, and an estimated USD 123.89 billion in economic losses.

🌊 **Key Trends & Impacts**
* The number of registered WRDs significantly increased during this period, partly due to improved data recording, especially after the S2ID platform launched in 2013. Droughts accounted for the highest number of events (53.61%) and economic losses (USD 72.50 billion), while floods caused the most deaths (2,662).

📈 **Regional & Categorical Breakdown**
* Impacts varied by region. The Northeast saw the most drought-related events and economic losses. The Southeast experienced the most flood and landslide deaths, while the South recorded the highest number of storm-related deaths. Over 91% of Brazilian municipalities reported at least one WRD.

For the first time ever, scientists comprehensively mapped all glaciers in the lower 48 US states. They found 1/4 disappeared and total area/volume shrank by 35% (195.29 km², 5.53 gigatons of ice) since the mid-20th century—reducing vital water runoff alpine ecosystems rely on to buffer droughts.
