Southern ocean heating due to ozone layer
Recommended for Preparatory Grades
Researchers have identified a lesser-known form of ozone as the major reason for heating the Southern ocean. The Southern Ocean also called as Antarctic Ocean, is one of the Earth’s main cooling systems.
What is ozone?
Ozone is a gas composed of three oxygen atoms.
The ozone layer helps in shielding people from the sun’s harmful radiation. When it is closer to the ground level, ozone is harmful to humans.
A new study about the heating of the Southern Ocean
University of California-Riverside scientists have conducted a study. According to scientists, lower level ozone is the main reason for heating the Southern Ocean.
The oceans tend to remove a majority of the carbon and heat that enter the atmosphere. The Antarctic Ocean collects one-third of all excess carbon in the world’s atmosphere. Adding to it, the Antarctic ocean holds approximately 75% of the excess heat collected by the world’s oceans. The increasing warmth of the ocean waters has led to rising sea levels.
Measures to control the heating
Scientists have created climate model simulations that show the changes in the ozone levels between 1995 and 2000.
The climate model isolates both stratospheric and tropospheric ozone layers from other influences that affect the Southern ocean. Scientists stated that they have found that the tropospheric ozone layer contributes more to the rising heat of the Antarctic or Southern ocean
