Coral, maybe a lot of people don’t know it is an animal, it made of bones and coral polyps. In recent years, coral bleaching is often in the news such as the coral bleaching crisis in northeast Australia. However, to this day, many people unaware of the problem caused by coral bleaching. Firstly, how climate change caused by coral bleaching? Coral bleaching occurs when the sea surface temperature rises more 1℃ than the seasonal maximum. Where there are coral colonies, there is a rich ecosystem, and when the coral bleaches, the ecosystem is destroyed.
Besides coral, polar bears are also the biggest victims of climate change. The polar bear is an animal that depends on sea ice to rest, hunt and reproduces. According to NASA observations, Summer sea ice in the arctic has fallen by almost half in the past 40 years. It leads to the total number of polar bears have mere 26,000 in the world and the number is decreasing year by year.
