The Ocean's Role in Climate Change
The ocean plays a crucial role in combating climate change by absorbing excess heat and carbon dioxide from the atmosphere. It is estimated that since the industrial revolution, the ocean has absorbed over 90% of the surplus heat generated by human activities, thereby preventing a significant increase in air temperatures. Additionally, the ocean absorbs about a quarter of atmospheric carbon dioxide, which mitigates the effects of global warming. However, this relationship is delicate; a healthy ocean is necessary to combat climate change, and reversing global warming is vital for maintaining ocean health.
