The heat wave in China has caused the river to go completely dry. Cloud seeding is a technique used to encourage more rain in order to combat the country's hottest temperatures on record.

This year's heat wave is affecting water security and crops, according to CNN. The technique shoots silver iodide rods, the size of cigarettes, high into the sky to create ice crystals, which hopefully will turn into rain.

Russia brought cloud seeding to China in the 1960's. China is estimated to produce 55 billion tons of water a year with cloud seeding, making it the top producer of water in the world today.

Rain Drain

Scientists haven't found any adverse effects on the human body from cloud seeding according to a medically-reviewed article.

The medical site says that the accepted limit for silver exposure is far below the amount of silver concentrated in the rain. There is currently no scientific evidence to prove that cloud seeding harms the environment or atmosphere.

Heating Up

Multiple nations are fighting intense, often record-breaking heat waves.

Failing power grids and international tensions over energy production are just two of the double whammies that come with the temp. We will see more interest in controlling the weather if the trend continues.
