Covering Flooding

Extreme rainfall is becoming more frequent and intense as our climate warms, leading to unprecedented flooding in communities across the world.

Story Spark: Flooding

More than 20 trillion gallons of water fell across the American Southeast as Hurricane Helene carved a path of “biblical devastation” made worse due to climate change.

Research (and physics) show that extreme rainfall is becoming more frequent and intense across the world as a warmer atmosphere can “hold” more moisture. Southern Appalachia is just the latest example, with Brazil, Nepal, Central Europe, Central and Western Africa, and many more also facing historic floods this year.

Climate change is expected to continue increasing flood risks across the country, especially the East and Gulf coasts. However, as we’ve seen in North Carolina, where 98% of homeowners don’t have flood insurance, extreme rainfall can occur far inland in areas once thought to be “climate havens.”

Reporting Tips

Rebecca HersherRebecca Hersher, a correspondent for NPR’s Climate Desk, offers tips for reporting on flooding. This year Hersher explored the human cost of climate change, highlighting the lives of loved ones lost due to flooding and extreme heat in a special series, “The Undercount.”

Include the larger climate context, even in short news stories. If a flood is record-breaking, note that record-breaking flooding is getting more common in many parts of the country as the planet warms. If a flood was caused by very heavy rain, note that such rainfall is getting more likely because a warmer atmosphere can hold more moisture. If a flood was caused by a high tide, note that sea level rise is causing high tide flooding to get more common.

Use simple superlatives to describe the magnitude of the flooding, such as “the most rain ever recorded in the area in such a short period of time.” Avoid terms like “100-year flood.” While such probabilistic language can be useful for statistics-minded scientists, it’s confusing and misleading for the general public because it suggests that, if you’ve experienced one 100-year flood, you won’t experience another in your lifetime. In reality, a 100-year flood has a 1-in-100 probability of happening any year. And that’s before you consider that such floods are getting more common in many places as Earth warms.

Focus on the personal impacts. Flooding is both deadly and expensive. Asking simple questions can help your reporting feel real to people. Who died, and how? What could have been done to prevent death or damage? Deaths from flooding are largely avoidable, and infrastructure usually plays a big part in where water collects and whose homes or livelihoods are affected.

Lean into the local angle. Flooding is a hyperlocal phenomenon — one street might be underwater while the next street over is dry. Question local floodplain managers, waste and stormwater authorities, transportation departments, and housing officials about why some places flooded and some didn’t. Such conversations can help drive your reporting in a more solutions-oriented direction, while also helping the audience explain who in the community is most at risk from flooding.
