For a half century, the military has been developing technologies to turn climate and extreme environmental phenomena into weapons. This study is a literature review. Results of the literature review reveal that HAARP (High-frequency Active Auroral Research Program), the most powerful ionospheric heater in operation, is able to influence climate. High-power electromagnetic pulses in the earth's crust, produced by a mobile magneto-hydrodynamic generator, is a technique developed since the 1970s to trigger earthquakes. Directed energy weapons, a real technology, can ignite destructive fires at range. For several years, official documents report effects on health and the environment similar in all aspects to those that would be detected if solar geoengineering by stratospheric aerosol injection, a climate-altering technique, was used. Due to numerous biases and a lack of objectivity, the IPCC's arguments on the causes of the growth in extreme environmental phenomena (heat and cold waves, storms, hurricanes, tornadoes, droughts, floods, wildfires, air pollution, etc.) are flawed. The solar hypothesis isn't appropriate either, given its low activity for several years. In conclusion, the use of military climatic and environmental modification technologies appears to be the most relevant explanation to understand the increase in natural disasters over the last 20 years.
