DisastersExtreme Rain Heads for California’s Burn Scars, Raising the Risk of Mudslides – This Is What Cascading Climate Disasters Look Like
Wildfires strip away vegetation and leave the soil less able to absorb water. A downpour on these vulnerable landscapes can quickly erode the ground as fast-moving water carries debris and mud with it. Wildfires strip away vegetation and leave the soil less able to absorb water. A downpour on these vulnerable landscapes can quickly erode the ground as fast-moving water carries debris and mud with it. Such consecutive events lead to human disasters. Studies show climate change is raising the risk of multiple compound disasters.

Climate & National SecurityBiden Administration Places Climate Change at the Center of U.S. Security Planning
The administration on Thursday has released a series of reports addressing the increasingly severe impact of climate change on U.S. national security – an impact which is only going to grow in severity and scope. Taken together, the reports signal a new stage in U.S. policy, one which places climate change at the center of the U.S. security planning.

ANALYSIS: Gathering StormRising Temperatures Reshaping, Exacerbating Global Security Landscape
More than just altering the environment, climate change is threatening to permanently and dangerously reshape the global security landscape. These are the conclusions of a series of new assessments by U.S. military, intelligence, and security officials. “As climate change converges with other drivers — especially geostrategic competition, emerging technology and global-demographic trends — it is reshaping the risk landscape,” DHS said in its assessment. “The corrosive impact of these trends will make nations increasingly vulnerable to domestic instability, with sweeping implications for regional and border security and core national security interests.”.

Infrastructure ProtectionUrbanites Face Heightened Flood Risk as a Result of Forest Loss
The devastating impact of flooding in Queensland’s north, exacerbated by forest loss, is badly affecting urban areas. Researchers found that deforestation near urban areas exposes these areas to much larger amounts of water flowing on the soil surface soon after a rainfall.

Climate ChallengesCities Worldwide Aren’t Adapting to Climate Change Quickly Enough
Climate change is magnifying threats such as flooding, wildfires, tropical storms and drought. cities are quickly becoming more vulnerable to extreme weather events and permanent shifts in their climate zones. The problem is that the pace of climate change is accelerating much more rapidly than urban areas are taking steps to adapt to it.

LandslidesUrban Areas More Likely to Have Precipitation-Triggered Landslides
Urban areas may be at greater risk for precipitation-triggered landslides than rural areas, according to a new study that could help improve landslide predictions and hazard and risk assessments. Researchers found that urban landslide hazard was up to 10 times more sensitive to variations in precipitation than in rural areas.

Water SecurityNuclear Physics Used to probe Floridan Aquifer Threatened by Climate Change
Florida is known for water. Between its beaches, swamps, storms and humidity, the state is soaked. And below its entire surface lies the largest freshwater aquifer in the nation. As rising sea levels threaten coastal areas, scientists are using an emerging nuclear dating technique to track the ins and outs of water flow.

DroughtsRecord-Breaking Texas Drought More Severe Than Previously Thought
In 2011, Texas experienced one of its worst droughts ever, with the dry, parched conditions causing more than $7 billion in crop and livestock losses, sparking wildfires, pushing power grids to the limit, and reducing reservoirs to dangerously low levels. A new study finds that the drought was worse than previously thought.

Hurricane IdaA 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.
FloodsScience’s Answers to Flood Disaster
On 14 July 2021, between 60 and 180 mm of rain fell in the Eifel region in just 22 hours - an amount that would otherwise have fallen in several months and which led to catastrophic flooding. The events were far more destructive than existing models had predicted.
