The Ocean

Climate change has affected the ocean in a number of ways. It has become clear that the temperature of the Earth is rising due to increased CO2 emissions. This heat has cause the ice caps of the sea to melt. This in turn has meant that sea levels are dramatically rising. This has severe implications for those on land.

It means that the devastating effects of erosion are only going to increase further. With higher sea levels the ocean will claim more land than ever before. This will be bad news for those living on the coast. It is a particular issue for those living in the city of Venice. The Mediterranean Sea is predicted to rise by as much as 140 cm. When this happens it will cause Venice to become submerged. It is certain that the city will disappear underwater unless climate change is properly tackled.

Coral reefs are a crucial part of the ocean ecosystems. They help to sustain the life of many underwater creatures. Climate change is the biggest threat to the seas and many coral reef structures. We have already seen the devastating effects that underwater warming has caused to them. Many are quickly dying in large numbers and so too with them are the fish that rely on them to live.

Mass bleaching events are the main reason behind these deaths. Furthermore, the increased amount of Carbon Dioxide within the reefs themselves has led to a weakness in coral structures. Ocean acidification has taken place throughout the seas of the world.

This is where greenhouse gases change the pH balance of the water. This has caused a plethora of problems which is making life unsustainable for a number of sea creatures. Increased heat means that infectious diseases are able to thrive and decimate organism populations.
