Hurricane Helene made landfall in Florida on Sept. 26, killing no less than 40 individuals and leaving a four-state swath of destruction.
Earlier than the hurricane’s affect, a social media consumer stated in a Sept. 25 submit that it was human-made. “So, right this moment we’re going to hit on this hurricane that’s going up into Florida and possibly determine who’s inflicting it,” the narrator stated as a picture of the storm’s projected path appeared behind him.
He cited a 1947 hurricane named “King” and stated it had the “very same path” as Helene. Hurricane King was the topic of an experiment carried out by the U.S. Air Power and Basic Electrical Co. referred to as “Venture Cirrus.”
“Hurricane Helene? Climate modification?” the caption learn.

There’s no proof that Hurricane Helene was fashioned via climate modification. Bart Geerts, professor on the College of Wyoming Division of Atmospheric Science, advised PolitiFact that’s “false.”
“NOAA confirms that there are not any climate modification actions that might have resulted in Hurricane Helene. Hurricanes kind on their very own given the proper circumstances and that was the case with Helene,” Monica Allen, director of public affairs for the Nationwide Oceanic and Atmospheric Administration Analysis division, advised PolitiFact.
Allen cited Venture Stormfury, a NOAA venture within the Nineteen Sixties that “concerned seeding present hurricanes.” Tried on 4 hurricanes, the venture studied how seeding clouds with silver iodide may result in a lower within the hurricane’s strongest winds.
“This venture led to 1983 as a result of it had, at finest, combined outcomes, and there have been considerations about unintended penalties,” Allen stated. “Since then, NOAA has accomplished no climate modification.”
Hugh Willoughby, who was concerned in Venture Stormfury, advised PolitiFact, “So far as I do know, no one within the U.S. is enterprise hurricane modification, and even has the potential.” Willoughby is a distinguished analysis professor on the Florida Worldwide College Division of Earth and Atmosphere and previously directed NOAA’s hurricane analysis division.
In accordance with the Atlantic Oceanographic & Meteorological Laboratory, Venture Cirrus — the venture the video cited — was an settlement between Basic Electrical Analysis Laboratory, the Naval Analysis Laboratory and U.S. Military Sign Corps to “seed” clouds and fog by dumping dry ice on them and discovering out what would occur.
The venture centered on a hurricane that struck Florida on Oct. 12, 1947. Miami’s Air Power Hurricane Workplace designated the storm “King,” a moniker derived from the navy’s phonetic alphabet throughout a interval earlier than hurricanes have been named as they’re now.
The day after the hurricane exited the state and was projected to proceed out to sea with out affecting any extra individuals, plane flew out and dumped dry ice into the hurricane’s clouds. The hurricane quickly swerved west and gained energy. It made landfall in Georgia on Oct. 15, 1947, inflicting one demise and hundreds of thousands in injury to Georgia and South Carolina.
The top of Basic Electrical Analysis Laboratory believed the storm modified course due to the experiment, however the climate bureau chief on the time, Dr. Francis Reichelderfer, disagreed. Willoughby stated the Venture Stormfury investigators have been “very cautious” after what occurred with Venture Cirrus, “though it’s unlikely that seeding had something to do with the change in observe.”
After Venture Cirrus got here Venture Stormfury, the findings from which confirmed that “cloud seeding had little prospect of success” and that it was tough to find out whether or not the adjustments occurred due to the experiment or due to the hurricanes’ pure conduct.
Willoughby stated the venture was deserted as a result of “its scientific foundation was discredited.”
We charge the declare that Hurricane Helene was a product of climate modification Pants on Fireplace!
CORRECTION, Sept. 29: We up to date this fact-check to make clear Monica Allen’s NOAA title.
