More Than 107M Americans Will Soon Live inside an Emerging “Extreme Heat Belt” with Temperatures above 125 F
Fifty U.S. counties, home to 8.1 million residents, are expected to experience temperatures above 125°F in 2023, the highest level of the National Weather Services’ heat index. By 2053, 1,023 U.S. counties are expected to exceed this temperature, an area that is home to 107.6 million Americans and covers a quarter of the U.S. land area.

Prediction of Human Movement During Disasters Allows More Effective Emergency Response
The COVID-19 pandemic, bigger and more frequent wildfires, devastating floods, and powerful storms have become facts of life. With each disaster, people depend on the emergency response of governments, nonprofit organizations, and the private sector for aid when their lives are upended. But there is a complicating factor: people tend to disperse with such disasters, making aid delivery more difficult.

For Advance Drought Warning, Look to the Plants
Among the extreme weather impacts resulting from climate change, drought is a growing problem around the globe, leading to frequent wildfires, threats to water resources, and greater food insecurity. Researchers find signals in vegetation can help forecast devastating ‘flash’ droughts.

Evacuating Outside the Lines
Researchers at the University of Tsukuba show how extending evacuation options to shelters outside the borders of a city can help increase the efficiency of flood responses, which may reduce the disruption caused by natural disasters.

Flood Maps Show U.S. Vastly Underestimates Contamination Risk at Old Industrial Sites
Floodwaters are a growing risk for many American cities, threatening to displace not only people and housing but also the land-based pollution left behind by earlier industrial activities. For communities near these sites, the flooding of contaminated land is worrisome because it threatens to compromise common pollution containment methods, such as capping contaminated land with clean soil. It can also transport legacy contaminants into surrounding soils and waterways, putting the health and safety of urban ecosystems and residents at risk.

Bringing Disaster Risk, Vulnerability Down to Community Level
A comprehensive update to NOAA’s Billion Dollar Disasters mapping tool now includes U.S. census tract data – providing many users with local community-level awareness of hazard risk, exposure and vulnerability across more than 100 combinations of weather and climate hazards.

Climate Change Is Making Flooding Worse: 3 Reasons the World Is Seeing More Record-Breaking Deluges and Flash Floods
Although floods are a natural occurrence, human-caused climate change is making severe flooding events more common. I study how climate change affects hydrology and flooding. In mountainous regions, three effects of climate change in particular are creating higher flood risks: more intense precipitation, shifting snow, and rain patterns and the effects of wildfires on the landscape.

Using Historical Weather Data to Optimize Power Grid
With the record-breaking heat and drought conditions states across the U.S. are currently facing, finding a solution to the growing need for reliable power from the electric grid is at an all-time high. Information about past outlier conditions could provide valuable context to help operators better manage the grid during extreme weather.

A Water Strategy for the Parched West: Have Cities Pay Farmers to Install More Efficient Irrigation Systems
Unsustainable water practices, drought and climate change are causing this crisis across the U.S. Southwest. To achieve a meaningful reduction in water use, states need to focus on the region’s biggest water user: agriculture.

New Flood Maps Clarify the Risk Homeowners Face
Flooding in urban areas cost Americans more than $106 billion between 1960 and 2016, damaging property, disrupting businesses and claiming lives in the process. Determining which areas are most likely to flood amid ever-changing land use and shifting rainfall and climate patterns can be expensive and complicated. New maps more realistically depict flood zones with less effort, lower costs.

U.S. Launches Heat.gov with Tools for Communities Facing Extreme Heat
The administration launched Heat.gov, a new website to provide the public and decision-makers with clear, timely and science-based information to understand and reduce the health risks of extreme heat. Heat.gov will provide a one-stop hub on heat and health for the nation and is a priority of President Biden’s National Climate Task Force and its Interagency Working Group on Extreme Heat.

The Surprising Reasons Floods and Other Disasters Are Deadlier at Night
It’s not just that it’s dark and people are asleep. Urban sprawl, confirmation bias, and other factors can play a role.
Why Flash Flood Warnings Will Continue to Go Unheeded
Experts say local education and community support are key to conveying risk.
