Global warming is impacting oceans in many ways. It is decreasing the level of oxygen, increasing ocean temperature, changing the oceans current, and impacting the lives of many species and marine animals. Let us discuss these points one by one.

Essay on Impact of Global Warming on Ocean

Increasing the temperature of Ocean

Global warming is increasing not only the temperature of the environment but also of oceans. Oceans are heating up more day by day, and this is the worst impact of global warming on oceans. In the last two decades, the temperature of oceans is increased by two times. This will impact the sea level of the ocean which will, in turn, affect the climate in a very bad way.

Deoxygenation due to Global Warming

Global warming increases the temperature of the water, which makes the water warm. And in warm water, oxygen is less soluble. Thus, oxygen in the ocean is reducing, which is known as Deoxygenation. Deoxygenation will, in turn, reduce the life span of fishes, and marine animals. Fishes will get lesser oxygen and will not be able to live longer. Furthermore, there are many people who are dependent on ocean and marine animals for their livelihood. Global warming is also affecting them indirectly.

Migration of Fishes

Fishes are not comfortable with the higher temperature of oceans. They are not getting enough oxygen to live. What are they going to do? They will migrate from one place to another. Most fishes are now migrating towards the northern pole because of deoxygenation and the increasing temperature of the ocean. This will impact a lot of things.

Ocean Current

Global warming is also impacting the ocean current levels. Due to changes in the ocean current levels, there is also a change in climate temperature, rain patterns are changing, and it is also disrupting the condition of weather. And once again, it is impacting the health of marine animals and species


Global warming is the first world problem that needs to be solved quickly. We need to stop water waste, use public transport instead of private transport, make the use of renewable energy more and more. There are a lot of things we humans can do to stop global warming. But we all need to unite, form strict rules and regulations and follow it.
