Due to greenhouse gas emissions, global warming is already 1°C higher than the pre-industrial levels. There is vast evidence that this has serious consequences for ecosystems and human being. The IPCC’s special report on Oceans and Cryosphere (published in 2019) reveals that the ocean is 0.8 degrees warmer than the pre-industrial age. It is more acidic, and less productive because of the carbon emission that was sunk by the oceans.
The impact of ocean warming would be an increase in the frequency of tropical cyclone winds and rainfall, as well as an increase in extreme waves, all of which would be accompanied by a rise in relative sea level.

Consider the following statements.1. The productivity of the Oceans in...
The ocean absorbs carbon-dioxide from the atmosphere because as the atmospheric concentration increases,more is dissolved in the water.The world's oceans have been sucking carbon dioxide out of the atmosphere and releasing it again in a steady inhale and exhale.
Consider the following statements.1. The productivity of the Oceans in...
Explanation:
Statement 1: The productivity of the Oceans increases when the carbon emission from the atmosphere are sunk by it.
This statement is incorrect. The productivity of the oceans does not necessarily increase when carbon emissions from the atmosphere are absorbed by it. While the oceans do act as a sink for carbon dioxide (CO2) emissions, excessive absorption of CO2 can lead to ocean acidification, which is harmful to marine life. When CO2 is absorbed by the oceans, it reacts with seawater to form carbonic acid, which lowers the pH of the water and makes it more acidic. This can have detrimental effects on many organisms, such as shellfish and coral reefs, which rely on calcium carbonate to build their shells and skeletons. Ocean acidification can disrupt the entire marine food chain and reduce the overall productivity of the oceans.
Statement 2: The ocean warming increases the frequency of tropical cyclone winds and rainfall.
This statement is correct. As the oceans warm, it provides more energy to tropical cyclones, which can lead to an increase in their intensity and frequency. Warmer ocean temperatures provide the necessary fuel for tropical cyclones to form and strengthen. The warm ocean water evaporates, creating moist air that rises and forms thunderstorms. These thunderstorms can develop into tropical cyclones, also known as hurricanes or typhoons, depending on the region. The increased energy from warmer oceans can lead to stronger wind speeds and heavier rainfall associated with tropical cyclones.
Conclusion:
Therefore, the correct answer is option 'A' - Statement 1 only. The productivity of the oceans does not necessarily increase when carbon emissions from the atmosphere are absorbed by it, and ocean warming does indeed increase the frequency of tropical cyclone winds and rainfall.
