Risks of Megafloods in California Increase
California is currently contending with historic drought, but climate change is sharply increasing the risk of a catastrophic megaflood that could submerge large swaths of the state and displace millions of residents. The frequency of catastrophic deluges increases as temperatures rise.

World's Biggest Ice Sheet Could Cause Massive Sea Rise Without Action
A new study shows that the worst effects of global warming on the East Antarctic Ice Sheet (EAIS) could be avoided. That depends upon temperatures not rising by more than 2°C above pre-industrial levels.

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.

Machine Learning Could Predict Rare Disastrous Events Like Earthquakes or Pandemics
Researchers suggest how scientists can circumvent the need for massive data sets to forecast extreme events with the combination of an advanced machine learning system and sequential sampling techniques.
Americans Are Flocking to Wildfire
People are trading hurricane zones for wildfire areas, says national study of migration, natural disasters, and climate change.
Insurance for a Changing Climate
Among the many facets of the economy being challenged and changed by warming global temperatures is the insurance industry. Damaging extreme events such as wildfires, hurricanes, and floods are happening with greater frequency and intensity, which leaves insurance companies facing larger financial risks and paying out more in claims — and it also leaves policy holders paying higher prices to insure their homes and businesses.
