Overview

  • Meteorologists and atmospheric scientists uniformly assert that cloud seeding can at most boost rainfall by around 20% in existing clouds and lacks the scale to trigger catastrophic flash floods
  • Rainmaker CEO Augustus Doricko confirmed the July 2 operation over Runge seeded two small clouds that dissipated within hours and did not contribute to the July 4 deluge
  • The EPA’s newly released online resources explain contrail formation and geoengineering science to dispel long-standing myths about weather modification
  • Florida and Tennessee have enacted bans on weather modification and lawmakers in other states, including Rep. Marjorie Taylor Greene, are advancing legislation to criminalize unauthorized seeding
  • A preliminary report by ClimaMeter found that human-driven warming significantly amplified the heavy rainfall responsible for the Central Texas floods
