Creating Rain Because Of Climate Change by micolea

It turns out rain can be induced after all.   

It was reported last month that a cloud seeding operation brought rain to provinces in Bicol, Philippines.  

To combat the rain and water shortage and aid farmers in saving their farms, the Philippine Department of Agriculture has distributed funding for cloud seeding. From airplanes, either salt crystals or dry ice are released into the clouds. The desired outcome of this process is to cause precipitation in clouds that will eventually lead to the formation of rain.

While the Philippine Islands is accustomed to experiencing mild droughts every year, this year is an exception. 

 The El Nino phenomenon has caused massive droughts for many regions in the Philippines, particularly in Luzon and Mindanao. This climate pattern is linked with droughts, floods and other turbulent weather. Typically, the countries most affected by the El Nino phenomenon are those surrounding the Pacific Ocean. The current dry spell has been plaguing the Philippine Islands and its farmers by causing crops to dwindle and diminish because of the lack of rain.

 I never knew a concept like artificial rain even existed. While on one hand, I think that this is a beneficial scientific process, which, in the Philippine’s case helped to restore peoples’ livelihood, I also believe that with innovation comes consequences. Rain is a natural circumstance. Artificial rain is not. So if rain continues to be created, it might end up contributing to the effects of climate change instead of resisting it. But is cloud seeding made valid if it is saving the lives and livelihoods of an entire country?  

Although the effects of cloud seeding can yield desired results like bringing much-needed rain to arid areas or in other cases halting rain, it can also produce undesired weather effects. For instance, the concentration of rainfall in one sector can lead to the reduction of rain in another. Other side effects include hail and even a decline in rainfall.  

My mother, who grew up in the Philippines, always tells me stories of her childhood. I distinctly remember a story she told me about how her family would make efforts to conserve water. For example, when taking a shower, she would turn off the water in between shampooing and conditioning her hair. Recently, in an effort to preserve water in larger, overpopulated Philippine cities, water is rationed on a daily basis. This means that at certain times of the day, for hours at a time, people do not have access to running water.   

Water is such a precious resource.  It flows throughout various aspects of our lives: we need it to keep us hydrated, to cleanse our bodies and to grow and harvest crops.  We need it for our survival. So while I am aware of the troublesome effects of cloud seeding, I support its use because of the potential it has to save many peoples’ means of subsistence.

Micole,

I have the same dilemma in my head about GMOs. I hate the thought of GMOs here in the US… but I don’t feel like I have the right to say that GMOs are wrong in third-world countries where the only way they can grow enough healthy food is to have a genetically modified crop. As far as cloud seeding goes, you might be interested in the cloud seeding that took place after Chernobyl (http://www.telegraph.co.uk/news/worldnews/1549366/How-we-made-the-Chernobyl-rain.html). -Kristina B.

Kristina,

Thanks for your comment and the link to the Chernobyl article- it was a very interesting read. I had no idea that cloud seeding was used to change the direction of rain. It seems as if cloud seeding is a very controversial issue- on one hand it can save lives and on the other hand it can also negatively affect them.
