Weather warfare is the use of weather modification techniques such as cloud seeding for military purposes.
Prior to the Environmental Modification Convention signed in Geneva in 1977, the United States used weather warfare in the Vietnam War. Operation Popeye saw the use of cloud seeding over the Ho Chi Minh trail. It was hoped that the increased rainfall would reduce the rate of infiltration down the trail. [1]
A research paper produced for the United States Air Force written in 1996 speculates about the future use of nanotechnology to produce "artificial weather", clouds of microscopic computer particles all communicating with each other to form an "intelligent fog" that could be used for various purposes. "Artificial weather technologies do not currently exist. But as they are developed, the importance of their potential applications rises rapidly."
The Environmental Modification Convention (ENMOD), which was signed in Geneva on May 18, 1977, and entered into force on October 5, 1978, prohibits "widespread, long-lasting or severe effects as the means of destruction, damage or injury". In 1972 an ENMOD convention on weather warfare presented that this permits "local, non-permanent changes". [2] The "Consultative Committee of Experts" established in Article VIII of the Convention stated in their "Understanding relating to Article II" that any use of environmental modification where this is done "as a means of destruction, damage or injury to another State Party, would be prohibited.". [3] It also suggests all signatories are expected to abstain from using weather modification to cause harm at any scale, stating "military or any other hostile use of environmental modification techniques, would result, or could reasonably be expected to result, in widespread, long-lasting or severe destruction, damage or injury." However, the treaty does not directly condemn military use of weather modification when it does not directly cause harm, [3] such as the United States' use of weather modification in the Battle of Khe Sanh in the Vietnam War. The limitations of the treaty, and its application only to signatory states, allow weather warfare to continue to play a role in warfare throughout the 21st century. The United States prohibits weather modification without permission of the United States Secretary of Commerce. [4] [5]
The Environmental Modification Convention (ENMOD), formally the Convention on the Prohibition of Military or Any Other Hostile Use of Environmental Modification Techniques, is an international treaty prohibiting the military or other hostile use of environmental modification techniques having widespread, long-lasting or severe effects. It opened for signature on 18 May 1977 in Geneva and entered into force on 5 October 1978.
Chemical warfare (CW) involves using the toxic properties of chemical substances as weapons. This type of warfare is distinct from nuclear warfare, biological warfare and radiological warfare, which together make up CBRN, the military acronym for chemical, biological, radiological, and nuclear, all of which are considered "weapons of mass destruction" (WMDs), a term that contrasts with conventional weapons.
The Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or other Gases, and of Bacteriological Methods of Warfare, usually called the Geneva Protocol, is a treaty prohibiting the use of chemical and biological weapons in international armed conflicts. It was signed at Geneva on 17 June 1925 and entered into force on 8 February 1928. It was registered in League of Nations Treaty Series on 7 September 1929. The Geneva Protocol is a protocol to the Convention for the Supervision of the International Trade in Arms and Ammunition and in Implements of War signed on the same date, and followed the Hague Conventions of 1899 and 1907.
The law of war is a component of international law that regulates the conditions for initiating war and the conduct of hostilities. Laws of war define sovereignty and nationhood, states and territories, occupation, and other critical terms of law.
Weather modification is the act of intentionally manipulating or altering the weather. The most common form of weather modification is cloud seeding, which increases rainfall or snowfall, usually for the purpose of increasing the local water supply. Weather modification can also have the goal of preventing damaging weather, such as hail or hurricanes, from occurring; or of provoking damaging weather against an enemy, as a tactic of military or economic warfare like Operation Popeye, where clouds were seeded to prolong the monsoon in Vietnam. Weather modification in warfare has been banned by the United Nations under the Environmental Modification Convention.
Cloud seeding is a type of weather modification that aims to change the amount or type of precipitation, mitigate hail or disperse fog. The usual objective is to increase rain or snow, either for its own sake or to prevent precipitation from occurring in days afterward.
Protocol I is a 1977 amendment protocol to the Geneva Conventions concerning the protection of civilian victims of international war, such as "armed conflicts in which peoples are fighting against colonial domination, alien occupation or racist regimes". In practice, Additional Protocol I updated and reaffirmed the international laws of war stipulated in the Geneva Conventions of 1949 to accommodate developments of warfare since the Second World War (1937–1945).
Herbicidal warfare is the use of substances primarily designed to destroy the plant-based ecosystem of an area. Although herbicidal warfare use chemical substances, its main purpose is to disrupt agricultural food production and/or to destroy plants which provide cover or concealment to the enemy, not to asphyxiate or poison humans and/or destroy human-made structures. Herbicidal warfare has been forbidden by the Environmental Modification Convention since 1978, which bans "any technique for changing the composition or structure of the Earth's biota".
War can heavily damage the environment, and warring countries often place operational requirements ahead of environmental concerns for the duration of the war. Some international law is designed to limit this environmental harm.
Military necessity, along with distinction, and proportionality, are three important principles of international humanitarian law governing the legal use of force in an armed conflict.
Operation Popeye was a military cloud-seeding project carried out by the U.S. Air Force during the Vietnam War in 1967–1972. The highly classified program attempted to extend the monsoon season over specific areas of the Ho Chi Minh Trail, to disrupt North Vietnamese military supplies by softening road surfaces and causing landslides.
Air warfare must comply with laws and customs of war, including international humanitarian law by protecting the victims of the conflict and refraining from attacks on protected persons.
Ecocide is the destruction of the environment by humans. Ecocide threatens all human populations who are dependent on natural resources for maintaining ecosystems and ensuring their ability to support future generations. The Independent Expert Panel for the Legal Definition of Ecocide describes it as "unlawful or wanton acts committed with knowledge that there is a substantial likelihood of severe and either widespread or long-term damage to the environment being caused by those acts".
The Geneva Conventions are international humanitarian laws consisting of four treaties and three additional protocols that establish international legal standards for humanitarian treatment in war. The singular term Geneva Convention colloquially denotes the agreements of 1949, negotiated in the aftermath of the Second World War (1939–1945), which updated the terms of the two 1929 treaties and added two new conventions. The Geneva Conventions extensively define the basic rights of wartime prisoners, civilians and military personnel; establish protections for the wounded and sick; and provide protections for the civilians in and around a war-zone.
A tectonic weapon is a hypothetical device or system which could trigger earthquakes, volcanic eruptions, or other seismic events in specified locations by interfering with the Earth's natural geological processes. It was defined in 1992 by Aleksey Vsevolodovich Nikolayev, corresponding member of the Russian Academy of Sciences: "A tectonic or seismic weapon would be the use of the accumulated tectonic energy of the Earth's deeper layers to induce a destructive earthquake". He added "to set oneself the objective of inducing an earthquake is extremely doubtful." Though no such device is known to have been built, tectonic weapons have occasionally appeared as plot devices in works of fiction.
A chemical weapon (CW) is a specialized munition that uses chemicals formulated to inflict death or harm on humans. According to the Organisation for the Prohibition of Chemical Weapons (OPCW), this can be any chemical compound intended as a weapon "or its precursor that can cause death, injury, temporary incapacitation or sensory irritation through its chemical action. Munitions or other delivery devices designed to deliver chemical weapons, whether filled or unfilled, are also considered weapons themselves."
United Nations General Assembly Resolution 31/72 referred the Environmental Modification Convention (ENMOD) “to all States for their consideration, signature, and ratification”. The resolution was adopted on 10 December 1976 at the 31st Session of the UN General Assembly. The convention aims to prohibit the military or other hostile use of environmental modification techniques that have widespread, long-lasting, or severe effects. The convention entered into force on 5 October 1978.
New physical principles weapons are a wide range of weapons or systems created using emerging technologies, like wave, psychophysical, and genetic weapons.
In international humanitarian law and international criminal law, an indiscriminate attack is a military attack that fails to distinguish between legitimate military targets and protected persons. Indiscriminate attacks strike both legitimate military and protected objects alike, thus violating the principle of distinction between combatants and protected civilians. They differ from direct attacks against protected civilians and encompass cases in which the perpetrators are indifferent as to the nature of the target, cases in which the perpetrators use tactics or weapons that are inherently indiscriminate, and cases in which the attack is disproportionate, because it is likely to cause excessive protected civilian casualties and damages to protected objects.
