Due to climate change, there are more regular occurrences of heatwaves, which cause droughts, and torrential rain, which is responsible for flooding. Although humans are the cause of much of it, maybe we have a solution too? For example, China, the UAE and the USA are at the forefront of research into methods of producing rain in drought-stricken areas. And some scientists are even thinking about investigating technologies which could cool the entire planet.
It might sound like science fiction, but weather modification is nothing new. In the 1940s, scientists discovered that dropping particles of silver iodide into cloud tops, made the tiny water droplets condense and could stimulate precipitation. That's called cloud seeding. This is a technique still being tested today with the aim of producing extra rainfall and, the
