The deep ocean is warming. Ocean heat content is seen by scientists as a sign of climatic change. Ocean heat content is the energy the ocean has accumulated. Heat cannot escape into space as a result of the on-going GHG emissions.
They are becoming hotter over time. As a result, the global sea surface temperature (SST) has increased by around 1 degree Celsius higher than 140 years ago. The quantity of SST is closely related to marine life. To continue serving as a carbon and heat sink, the oceans must have a carrying capacity.
The life and time of animals that have developed in accordance with the temperature zone are also thrown off by increased warming since the temperature below the surface rises. Global climate patterns will change as a result of changes in ocean temperatures and currents.
This will raise the levels of dissolved carbon after a certain threshold. The foundation of the dynamic living life in the oceans will become poisoned as a result of this because it will further alter the chemistry of the saltwater by making it more acidic.
A population collapse would result from numerous species, including coral and shellfish, being unable to construct their shells or skeletons in acidic water. The equilibrium of the predator-prey feeding cycle would be upset as a result.
Since 1998, ocean heat content has changed in all six major oceans. However, the southern waters experienced the most warming. During the period of 2005 to 2011, the region accounted for about 90% of the net worldwide ocean heat gain.
According to the 5th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), which was published in 2013, the oceans have by far absorbed 93% of the additional energy from the greenhouse effect as the global greenhouse gas (GHG) emissions caused by human activities have been increasing exponentially. This assessment also says that over 90% of the global warming caused by humans during the 1970s has been absorbed by the oceans.
The expert noted that the ocean’s constant warming has an effect: Tropical storms and cyclones have grown more active, powerful, and larger, creating havoc by harming people and property.
