As residents worked frantically to drain water from homes and businesses, many started asking: did human interference with the weather contribute to this record-breaking deluge? Specifically, did the United Arab Emirates’ long-running cloud seeding program have unintended consequences?

What is Cloud Seeding?

Cloud seeding is a technique intended to increase rainfall in dry regions. The most common method involves spraying silver iodide or dry ice into suitable clouds to encourage the growth of rain droplets. The additional particles give water vapor more surfaces to condense upon. In theory, this causes the clouds to precipitate more intensely over a targeted area.

The concept of “seeding” clouds has been around since the 1940s. Governments and private companies have researched and utilized it in over 50 countries worldwide. The benefits are obvious for arid places like the UAE, which receives less than 4 inches of rain per year on average. Even modest increases to that total are considered worthwhile for agriculture and drinking water reserves.

Dubai has invested heavily in cloud seeding technology in recent years. The National Center of Meteorology runs 8 cloud seeding operations centers across the UAE. Its aircraft and drones dispersed over 187 tonnes of silver iodide in 2021 alone. But while the program often draws media attention when rains arrive, scientists debate how much cloud seeding actually impacts precipitation.

Does Cloud Seeding Cause Extreme Flooding?

The Dubai floods dropped over 5 inches of rain in some spots – more than the city would expect in an entire year. Could an aggressive cloud seeding program unintentionally dump such high volumes of water?

Experts say no. Cloud seeding can enhance rainfall, but not to such an extreme degree. The heavy downpours that swamped Dubai were the work of natural weather systems, not human intervention.

Several meteorologists noted that computer forecast models predicted significant rainfall up to a week in advance – an indicator that intense storms were building on their own. The models aren’t designed to account for cloud seeding.

The flooding was also consistent with climate change projections of more extreme weather, rather than typical cloud seeding results. While seeding may give an extra sprinkle or even a few inches at most, it doesn’t generate such high accumulations. The unprecedented single-day rainfall was far beyond expected outcomes of the technology.

Controversy Around Weather Modification

Nonetheless, some observers were quick to blame Dubai’s unnatural downpour on the cloud seeding program – potentially to distract from climate change impacts. Weather modification remains controversial despite decades of research and real-world application.

Critics argue that seeding clouds has unproven effectiveness along with risks of unintended consequences. Enthusiasts counter that even modest rainfall increases make the technique worthwhile for drought-prone regions. The debate has raged since the earliest cloud seeding tests in the 1940s.

Dubai relies heavily on cloud seeding to supplement its meager annual rainfall. But while the technology may give a boost, scientists say it clearly wasn’t the cause of July’s record-shattering floods. The true culprit was an unusually strong storm system – one that could become more common as global temperatures rise in the years ahead.
