An article by the website ProPublica titled The Flooding Will Come “No Matter What” linked to Hurricane Katrina, storm refugees, and climate change, claiming that the storm was evidence of the beginning of a “climate migration” in America. [emphasis, links added]
The connection is false. Data refutes a climate connection to any particular hurricane or trend in migration.
The article does a lot of rambling coverage of a family that was displaced by Hurricane Katrina back in 2005, saying:
Another great American migration is now underway, this time forced by the warming that is altering how and where people can live. For now, it’s just a trickle. But in the corners of the country’s most vulnerable landscapes — on the shores of its sinking bayous and on the eroding bluffs of its coastal defenses — populations are already in disarray.
The article goes on to follow the trials and tribulations of a single family who had their home destroyed during Hurricane Katrina.
ProPublica believes this case is evidence of climate change causing a “migration,” because the family has not moved back to the same location.
The article itself cites no data or study to support its claim about Hurricane Katrina. Rather, it simply states the author’s opinions as if they were established facts.
Later the article similarly describes families displaced by the 2018 Camp Fire in Paradise, Calif., as climate refugees, writing:
As the number of displaced people continues to grow, an ever-larger portion of those affected will make their moves permanent, migrating to safer ground or supportive communities. They will do so either because a singular disaster like the 2018 wildfire in Paradise, California — or Hurricane Harvey, which struck the Texas and Louisiana coasts — is so destructive it forces them to, or because the subtler “slow onset” change in their surroundings gradually grows so intolerable, uncomfortable or inconvenient that they make the decision to leave, proactively, by choice.
First, it should be noted that weather events such as hurricanes are not proof of climate change, and ProPublica is falsely conflating short-term weather events with long-term climate change.
Further, as discussed in Climate at a Glance: Hurricanes, even the U.N. Intergovernmental Panel on Climate Change (IPCC) admits to finding no increase in the long-term frequency or severity of hurricanes.
Also, after Katrina, the United States went through its longest period in recorded history without a major hurricane strike and recently experienced its fewest total hurricanes in any eight-year period.
There has been no increase in the number or intensity of tropical cyclones since 1972 as the planet has modestly warmed. Indeed, for some basins, the data suggests tropical cyclone frequency has declined over the past century.
Data presented in more than 100 previous Climate Realism posts here, here, here, and here, for example, clearly show that hurricane trends have been relatively flat over the past 50 years of modest warming, and the trend in powerful Atlantic hurricanes is downward (see the figures below).
Simply put, contrary to the claims made by ProPublica, there is no upward trend in hurricane frequency or intensity and thus claims that climate-driven migration is leaving “populations in disarray” are completely false.
The claim made about the wildfire in Paradise, Calif., causing “climate-driven migration” is equally false.
Paradise burned to the ground during the 2018 Camp Fire, which was due to a lack of maintenance on Pacific Gas and Electric power lines. That was combined with a weather event causing high winds on a single day and low fuel moisture to create the perfect storm of flammability.
California’s drought at the time was certainly a contributing factor, though drought has been historically common across the region, due to periodic weather patterns in the Pacific Ocean.
These patterns have occurred for millennia and are not a feature of man-made climate change. In fact, tree-ring studies of the western United States show past mega-droughts lasted as long as 200 years at times.
A report from California State University notes active forest management is a key practice in preventing wildfires.
“One of the reasons we’re observing more fires is because of 100 years of poor Forest Service policy where we didn’t allow prescribed fire or wildfires to burn,” says Dr. Craig Clements, a San Jose State University meteorology and climate science professor and director of the school’s Fire Weather Research Laboratory.
So, poor forest management and poorly maintained power lines affected by weather led to the wildfire devastation in Paradise, not climate change.
ProPublica simply failed to do basic research, relying on opinion and storytelling instead of factual reporting to weave yet another misleading story where climate change is blamed as part of the ongoing narrative told by the media blaming climate change for everything bad, even when the facts clearly say otherwise.

Had a neighbor who was a licensed insurance adjuster in five states, He was allowed into the Katrina damaged area even before property owners were permitted to return. He showed me some of the photographs he took. The house in the lead picture came through in better shape than most others.

The climate change movement continues to treat any undesirable event as new, unprecedented and claim it never happened before. After being flooded out a number of years in row, in 1903 my grandfather’s family moved from Illinois to Oregon. On the way to Oregon my grandfather was born in a barn.
