WORLD War 3 could be fought with “weaponised” weather by paralysing countries with apocalyptic flash floods or icy fog, experts fear.

Sabotaging the weather could “control enemies” and disrupt military operations during conflict – or be used by terrorists to launch attacks.

Weather modification encompasses efforts to increase rainfall, prevent rain, minimize hail, disperse fog, create snow, or lessen the impact of hurricanes.

This concept has been historically applied in various instances, such as during the Vietnam War, the 2008 Olympics in China, Russian events under Putin’s leadership, and by the British government.

But it’s feared weather sabotage could set off a chain of events “that we have little control over”.

If weaponised, it could stop rainfall over crops to starve a nation – or spark floods to damage infrastructure.

During a war, fighter planes could be smashed by hailstones, tanks could be frozen and warships could be forced to navigate icy fog.

According to Dr. Jim Flemming, a weather expert, “During the Cold War, military leaders believed that controlling the weather meant controlling the world.”

“You can control the enemy; you can do anything you want.”

Hamish de Bretton-Gordon, former chemical weapons adviser for the British military, told The Sun it was a “very plausible” threat.

He said: “You need the oxygen in a cloud to mix with a chemical to create a toxic substance – it would be very hit and miss.

“But if you are not concerned about indiscriminate casualties and just want to create terror and fear, it could be pretty effective.”

“If you seeded a cloud which then produced ‘acid-rain’ you could conceivably say it is a chemical weapon.

“The same goes if you seeded a cloud which then rained on crops… that could be chemical warfare.”

Dr. Alan Robock from Rutgers University explained, “In warfare, one could generate particle clouds to disrupt the precision of enemy laser-guided weapons.”

“Cloud seeding,” a technique using airplanes, involves dispersing chemical-laden pellets into clouds to increase ice crystal formation and thereby enhance rainfall.

Aircraft can also burn special salt flares to increase rainfall.

This means it has the potential to cause flash floods if it’s misused by rogue actors.

Other techniques include Britain using “brute force” during World War Two to control the weather for bombers returning in thick fog from Europe.

Dr. Robock also mentioned, “They would line the runway sides with gasoline trenches and ignite them to heat the air, causing clouds to evaporate.”

Johan Jaques, a senior meteorologist at tech company KISTERS, fears it’s these types of technology could be exploited to spark “weather wars”.

Last year, when Dubai was swamped by floods, many theorised that it was caused by cloud seeding.

He said: “The Dubai floods act as a stark warning of the unintended consequences we can unleash when we use such technology to alter the weather.

“Additionally, we have little control over the aftermath of cloud seeding.

“Where exactly is it going to be raining effectively? Using techniques such as cloud seeding to bring much-needed rainfall in one area can cause flash floods and droughts in another.”

He said: “Anytime we interfere with natural precipitation patterns, we set off a chain of events that we have little control over.

“While there is a lot we know, there is still a lot we don’t and there are still plenty of gaps in our understanding of these complex weather systems.

“Interference with the weather raises all kinds of ethical questions, as changing the weather in one country could lead to perhaps unintended yet catastrophic impacts in another.

“After all, the weather does not recognise intentional borders.

“If we’re not careful, unrestrained use of this technology could end up causing diplomatic instabilities with neighbouring countries engaging in tit-for-tat ‘weather wars’.”

Andrea Flossmann, a scientist at the World Meteorological Organisation, explained in a WMO report: “The atmosphere has no walls.

“What you add may not have the desired effect in your vicinity, but by being transported along might have undesired effects elsewhere.“

In 1977, the UN banned all military or hostile use of environmental modification techniques.

Since then, countries have tried to use weather modification for civil purposes – but there is no evidence that they necessarily worked.

Dr Flemming said: “We know now the Mongolian and Chinese dust clouds come across into Korea.

“And there are a lot of transboundary concerns. There are concerns in Europe as well.

“These things do trigger concerns. And the people planning for things have to think about those things.”

And the scientist fears these techniques could be weaponised in the “worst case scenario”.

He told The Sun: “I think you have to think of the worst case scenario which would be a rogue actor, whether it’s a rogue billionaire hoping to do good or a rogue nation – they could intervene.

“There’s this theory of nuclear winter, so you could trigger off some very adverse effects.

“But I see the risk as being too great. I see it as something that is not desirable at all.”

He added: “It’s the scale of what you would have to do that is sort of beyond even small countries.

“You need rich countries like China or the United States to develop a program over many years, and the only way it would make any sense is for all the countries to agree to do it.

“Not one country wants the climate one way.

“How do you set the planetary thermostat? If people don’t agree on how to do it, that could lead to conflict.”

Cloud seeding has been branded dangerous by some scientists and medics over fears that the chemicals that are dropped can be toxic to animals.

There are also concerns over what the artificial process could do to the earth’s natural weather patterns if rogue actors interfere.
