From ‘Cloud seeding rumours are false, malicious: MEWR Minister Vivian Balakrishnan’, 17 Sep 15, article in CNA
Rumours that cloud seeding is taking place to induce rain ahead of the Singapore Grand Prix are false, Minister for Environment and Water Resources Dr Vivian Balakrishnan said.
Addressing a WhatsApp message that has been making the rounds in Singapore, Dr Balakrishnan posted on Facebook on Thursday (Sep 17): “The National Environment Agency does not engage in cloud seeding and has no plans to do so. Singapore is so small that even if anybody tried to do it, the rain would almost certainly fall outside Singapore.”
He added: “Singaporeans should beware of malicious people spreading false rumours during a period when anxieties are heightened.”
The original WhatsApp message called for people to be wary of what it claimed were “chemically-induced rain showers”, purportedly meant to reduce haze levels in light of the coming Formula 1 race, which will be held on roads in Singapore’s Civic District from Sep 18 to 20.
In 2006, the NEA did in fact conduct a feasibility study on cloud-seeding to combat the annual haze scourge (S’pore may make own rain to beat the haze, 17 Nov 2006, ST). If you go further back to 1963 when the country was drought-hit, we embarked on the first ever rain-making attempt by sending a Royal Australian Air Force DC-3 up into the air. It is not known if that crew was actually successful, or the lack of suitable clouds to fertilise put a damper on their efforts. That probably works on the parched Outback, but not on our little pinprick of an island. Alternatively, you could try to pray for 4 hours, like what our Sikh community did that same year. I wonder what precipitated out of that. So, yeah, the possibility of us ‘playing God’ and dabbling in rainmaking is not as outright incredulous as the MEWR minister makes it seem.
Rumours of using this expensive technique, the science behind which is still rather ‘hazy’, to bring on the showers aren’t new to Singaporeans. We hear of it being done to deplete the clouds of their load so that the National Day Parade would be rain-free. But why hire a pilot and an aircraft full of silver iodide when you could do something far cheaper, and simpler, a method even endorsed by our PM himself: Making an offering chillies and onions to the rain deities.
Conspiracy theorists may recall how the US War machine supposedly weaponised the weather using aggressive cloud seeding over Vietnam. Code named Operation Popeye, the mission was to ‘reduce trafficability’ along infiltration routes. A war euphemism for torrential rain, floods and landslides. Apparently not everyone dreams of making it rain meatballs.
Cloud seeding by our neighbouring countries has also been linked with hailstones, a speculation that was firmly debunked by NEA for the reason that rain clouds formed by such seeding cannot travel such long distances to reach us. Till today, there remains no clear explanation for the freak weather we had post-haze in 2013. Not everyone complains about this ‘raining like ice cubes’, though.
