Essay on change in the oceans?
Answers
Oceans are beautiful, but Global Warming is ruining them. Global warming is becoming one of the major problems for the whole world. It is affecting our health, reducing the life span of animals, and also impact oceans. In this essay on global warming, we will see how it impacts oceans.
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.
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.
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.

Climate Variability
The ocean is a significant influence on Earth's weather and climate. The ocean covers 70% of the global surface. This great reservoir continuously exchanges heat, moisture, and carbon with the atmosphere, driving our weather patterns and influencing the slow, subtle changes in our climate. The oceans influence climate by absorbing solar radiation and releasing heat needed to drive the atmospheric circulation, by releasing aerosols that influence cloud cover, by emitting most of the water that falls on land as rain, by absorbing carbon dioxide from the atmosphere and storing it for years to millions of years. The oceans absorb much of the solar energy that reaches earth, and thanks to the high heat capacity of water, the oceans can slowly release heat over many months or years. The oceans store more heat in the uppermost 3 meters (10 feet) that the entire atmosphere, the key to understanding global climate change is inextricably linked to the ocean. Climate is influenced by storage of heat and CARBON DIOXIDE in the ocean, which depends on both physical and biological processes.
