Threat of Catastrophic Supervolcano Eruptions Ever-Present
Supervolcanoes remain active and hazardous for thousands of years after a super-eruption, prompting the need for a rethink of how these potentially catastrophic events are predicted.

Evaluating Wildfire Hazard
Severe wildfire disasters are often the product of numerous factors coalescing — vegetation, drought, a lack of firefighting resources, and many others. Identifying which factors are the most important is not always a simple task for local leaders assessing their community’s risk for damaging wildfires.

A Preview of What’s to Come: Climate Change Helped Intensify Hurricane Ida
Hurricane Ida started as a disturbance in the Atlantic Ocean quickly grew to what could be the worst hurricane to hit Louisiana since Hurricane Katrina in 2005. While scientists are uncertain whether climate change will increase the frequency of hurricanes, one thing is clear: Climate change is here, and it’s making these storms stronger and more destructive.

Keeping First Responders Safe by Detecting Cyanide Poisoning after Fires
When first responders rush to a burning building to subdue the fire and save lives, it is not just the flames that are dangerous and potentially lethal, but also toxic fumes like cyanide that are released when certain materials are incinerated. These fumes, mixed with smoke, are so toxic that even in very low quantities may pose more risk than the fire itself. Chemists at DHS S&T have invented a test to indicate possible toxic cyanide exposure at the fire scene.

Hurricane Ida Shows the Increasing Impact of Climate Change Since Katrina
While no two disasters are the same, looking at differences between past and present disasters can help us to better understand what is needed to prepare for future disasters. Given the scope of the emerging impacts of Hurricane Ida, we see that while this is not a repeat of a Katrina disaster, questions are being raised about the effect of climate change and the resiliency of lifeline infrastructure like electricity.

Can Burying Power Lines Protect Storm-Wracked Electric Grids? Not Always
Electricity is critical for health, safety and comfort. People wonder whether their electricity service might be more secure if those lines were buried underground. But I’ve studied this question for utilities and regulators, and the answer is not straightforward. There are many ways to make power grids more resilient, but they are all costly, require the involvement of many agencies, businesses and power customers, and may not solve the problem.

How Climate Change Will Affect Conflict and U.S. Military Operations
“People talk about climate change as a threat multiplier,” said Karen Sudkamp, an associate director of the Infrastructure, Immigration, and Security Operations Program within the RAND Homeland Security Research Division. “But at what point do we need to start talking about the threat multiplier actually becoming a significant threat all its own?”
