Adaptation plans don’t account for groundwater in shallow coastal aquifers, which can rise with sea levels, increasing the risk of flooding and damage.
Computer models of the storm hitting different areas show how much damage is possible, yet flood maps still focus on where flooding is most likely instead.
A nationwide scheme known as Flood Re is only a temporary fix.
Adaptation and planned relocation are unaffordable for at-risk communities and tangata whenua. Government cost-sharing is essential.
Australia has a comprehensive national database on property-level flood risk. But it is currently proprietary, meaning the public can’t access this valuable information.
More powerful storms and melting glaciers are flooding communities across the region again, with devastating effects, particularly in the mountains.
FEMA flood maps are essential tools for identifying flood risks, but they have significant coverage gaps, and politics can get in the way.
Flooding in eastern NSW shows just how vulnerable rural catchments and regional communities are to extreme and extended rainfall events.
Research shows hospital administrators can better plan for how they’d cope if a disaster or terrorist attack impacts a hospital’s ability to function as normal.
Flood maps are difficult to decipher. But understanding the risk is critical for people wanting to live and work by the coast.
Restraining rivers through stop banks and channels transfers and heightens flood risks downstream. Allowing them to roam free limits flooding and delivers other ecological benefits.
The latest floods exposed the deep vulnerability of many mountain communities in eastern Kentucky, where land ownership patterns and other barriers to recovery can leave residents with few options.
If federal streamgages were bolstered by networks of cheaper monitors run by communities, the results could save lives.
Low-income households are attracted to more affordable housing in areas at higher risk of floods and other extreme events. But many then find they cannot afford soaring insurance premiums.
Disasters such as hurricanes Helene and Milton often hit low-income and other disadvantaged groups hardest. 2 policy experts suggest ways long-term aid could help.
These powerful ‘rivers in the sky’ provide a huge share of annual precipitation in many regions, including California. They can also melt sea ice, with global climate implications.
People living near these industries, as well as emergency responders, often have few details about the chemicals inside. New interactive maps pinpoint the risks.
Australia is facing climate hazards on all fronts this spring and summer. Climate scientist Andrew King walks us through the Bureau of Meteorology’s new national outlook.
With Debby’s storm track, much of the East Coast is forecast to get soaked. Climate change also plays a role in the downpours.
