Coral Bleaching and Climate Change Quiz

The video discusses major coral bleaching events on the Great Barrier Reef in 1998, 2002, and 2016, highlighting the severe impact of extreme temperatures. Surveys revealed many corals were already dead due to these conditions. The bleaching phenomenon is not limited to the Great Barrier Reef but is also observed across the Pacific and Indian Oceans, and similar events are predicted globally. The video emphasizes the urgent need for a transition to renewable energy, as agreed upon in the Paris Agreement, to mitigate climate change and its effects on marine ecosystems.
