What is cloud seeding and cloud brightening?

This week, host Willy Lowry looks at how the UAE harnesses the rain with cloud seeding and Australia's effort to save the Great Barrier Reef through cloud brightening. We hear from Dr Deon Terblanche, a consultant in weather and climate at the World Bank, and Omar Al Yazeedi from the National Centre for Meteorology. We also speak to Daniel Harrison at the Sydney Institute of Marine Science.
