This year, 2018, is the third International Year of the Reef (IYOR2018). How are coral reefs surviving in the face of ever-increasing global warming and environmental stress? The talk will cover: aspects of climate change; coral reefs and why we should care about them; reefs in the Caribbean and in the Indo-Pacific; effects of environmental stress, adaptation and evolution in extreme environments and how that can help us understand climate change mitigation; moving from science to conservation, and some of the latest modelling of geoengineering and solar radiation management. And what can we do to help them become resilient and survive in the future.
