Flash Droughts Becoming Big Concern for Farmers, Water Utilities
Many people are familiar with flash floods – torrents that develop quickly after heavy rainfall. But there’s also such a thing as a flash drought, and these sudden, extreme dry spells are becoming a big concern for farmers and water utilities.

Global Warming Doubled the Risk for Copenhagen’s historic 2011 Cloudburst
On 2 July 2011, the Danish capital Copenhagen suffered a cloudburst of historic proportions, causing damage and destruction costing billions of kroner. Researchers have used detailed weather models to clearly tie increased temperatures to that historic cloudburst.

Gone with the Wind? Huskers Investigate Mystery of Last Standing Grain Bin
More than 750,000 steel silos and bins are estimated to pepper rural America, often standing empty before filling up on the annual harvest. Most cannot withstanding winds of 100-plus miles per hour – but some can.

Probable Maximum Flood Events Will Significantly Increase Over Next Decades
The flood capacity of dams could be at greater risk of being exceeded due to out-of-date modelling for potential maximum rainfall. A new study concludes that the rainfall model that engineers use to help design critical infrastructure such as large dams and nuclear power plants need to be updated to account for climate change.

Improving Canada’s Resilience to Flooding
Climate change is having a direct impact on natural disasters, including flooding, increasing the scale, frequency, and unpredictability of these events. The government of Canada said that is why it is making investments to strengthen Canada’s resilience to climate change and reduce the impact of flooding on our communities.

Maintaining Mountain Snowpacks Essential for Preserving Valuable Freshwater Resource
Snowcapped mountains generate mountain water runoff and snowmelt, which flow down to streams, rivers, lakes, and oceans. Around a quarter of the world depends on these natural “water towers” to replenish downstream reservoirs and groundwater aquifers for urban water supplies, agricultural irrigation, and ecosystem support. Carbon mitigation strategies are needed to maintain snowpack throughout the Americas.

Using 1980s Environmental Modeling to Mitigate Future Compound Disasters
On March 11, 2011, multiple catastrophes in Japan were triggered by the Great East Japan Earthquake, including the nuclear accident at the Fukushima Daiichi Nuclear Power Plant. This event, also known as the 3/11 disaster, is what is known as a compound disaster. Now that over a decade has passed since this event, researchers are investigating how to prevent the next compound disaster.

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?”
