This week, the World Meteorological Organisation has warned that a potentially exceptional El Niño is firmly established in the Pacific and is expected to strengthen significantly, increasing the risks of extreme heat, flooding, and drought around the world.

Joining Pat to discuss is Peter Thorne, Director of the ICARUS Climate Research Centre at Maynooth University.
