Whereas wanting into Birmingham, Alabama, chief meteorologist James Spann‘s new climate community, we noticed that he felt compelled to get on social media lately to elucidate away conspiracy theories surrounding the lethal Texas floods that killed greater than 100 folks earlier this month.
Some, together with lawmakers like Georgia Republican Congresswoman Marjorie Taylor Greene, have pushed theories that chemtrails and/or cloud seeding had been answerable for the floods that killed over 100 folks in Texas. Chemtrails are the fictional perception that long-lasting condensation trails left within the sky by high-flying plane are made up of chemical or organic brokers for undisclosed nefarious functions.
Greene stated on social media that she was introducing a invoice to ban cloud seeding and different climate modification.
Spann responded on Fb to what he described as “nasty messages and verbal threats” from the disinformation about how the climate works.
After receiving piles of nasty messages and verbal threats in current days, I felt the necessity to share this info.
Cloud seeding didn’t trigger final week’s Texas floods.
*Cloud seeding can solely improve rain from present clouds by as much as ~20%—it can’t create large deluges.
*The final reported cloud‑seeding flight by Rainmaker Expertise occurred on July 2, over 24 hours earlier than the floods started, and the seeded clouds had already dissipated.
*The flooding stemmed from a stalled climate system, bringing 10–20 inches of rain final Thursday and Friday. This was fueled by moisture from Tropical Storm Barry, Gulf air, and hill‐nation geography infamous for flash floods. That is nothing new for the Guadalupe River.
Backside line: The Texas floods had been attributable to pure climate dynamics—not human interference or climate modification efforts. It was not attributable to Democrats or Republicans. 
Once more this morning, I’m asking that you simply put the political rhetoric and nonsense conspiracy stuff apart for some time… let these poor households grieve. Contemplate empathy and kindness. Thanks.
