”Super” El Niños and climate change

Scientists say the El Niño weather pattern has started and this one is potentially so strong that it could have devastating effects in many parts of the world. So how does El Niño work exactly? And what’s the connection with climate change?

El Niño starts when water temperatures rise near the Pacific coast of South America, but the impact on weather is felt around the globe. Some regions are more likely to experience severe droughts or more powerful storms; others could face the threat of severe flooding.

This “Super” El Niño is likely to add 0.2 or 0.3 degrees to the global temperature. When added to the impact of climate change, scientists say the world could be headed for a new heat record in 2027.

In this edition of The Climate Question, hosts Graihagh Jackson and Jordan Dunbar chat to Mark Maslin, Professor of Earth System Science at University College, London, about what might happen and how the world can prepare.
