Wildfires Threats Not Commonly Disclosed by U.S. Firms Despite Risk to Economy
Wildfires in the United States, especially in Western states, increasingly pose a significant risk to entire communities, often destroying homes, businesses and lives. Yet U.S. firms rarely report their wildfire risks in required federal filings and instead bury such risks in nonspecific risk disclosures.

Addressing the Needs of Underprepared Communities
Many regions in the U.S. do not have regular earthquakes. Still, they have faults that can create large earthquakes, and communities in these regions are not prepared to experience a large quake with the capacity to cause significant damage. A new center will specifically address areas of low probability of occurrence but high impact earthquake risk and seek to meet the needs of all communities for natural hazard mitigation.

2022’s U.S. Climate Disasters: A Tale of Too Much Rain – and Too Little
The year 2022 will be remembered across the U.S. for its devastating flooding and storms – and also for its extreme heat waves and droughts, including one so severe it briefly shut down traffic on the Mississippi River.

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The flood capacity of dams could be at greater risk of being exceeded due to out-of-date modelling for potential maximum rainfall.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.

With Climate Impacts Growing, Insurance Companies Face Big Challenges
The impacts of climate change are all around us: sea level rise, severe heat waves, drought, extreme rainfall, more powerful storms. These impacts are making natural disasters more intense and more frequent. Losses from each disaster—drought and wildfires in the southwest, severe storms in the Midwest, flooding in Kentucky and Missouri, and hurricanes in the southeast—have exceeded $1 billion, with the cumulative cost of disasters over the last five years reaching $788.4 billion.

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.
