"Let's put an end to the conspiracy theories and stop blaming others," Texas Agriculture Commissioner Sid Miller said in a statement.

"There has been a lot of misinformation flying around lately, so let me clarify: the Texas Department of Agriculture has absolutely no connection to cloud seeding or any form of weather modification," Miller said in a statement.

The Gulf, which borders Texas, has become significantly warmer in recent years due to climate change, Swain explained. This results in a very warm body of water that produces a lot of evaporation, releasing more tropical moisture into the air than seen historically.

"These are roughly one-in-1,000-year events, [and] would be extremely rare in the absence of human-caused warming,” one climate scientist says.

As a succession of thunderstorms fed by the remnants of Tropical Storm Barry pummeled Texas' Hill Country, tools used by the National Oceanic and Atmospheric Administration to detect extreme rainfall began “maxing out the color charts.

Texas Hill Country is no stranger to extreme flooding. In the rugged, rolling terrain it’s known for, heavy rains collect quickly in its shallow streams and rivers that can burst into torrents like the deadly flood wave that swept along the Guadalupe River on July 4.
