The momentum between absorption and redemption of N2 in the ocean is changing. And that could increase climate change in the long run.
The Antarctic Peninsula in western Antarctica is facing the consequences of climate change. The region suffers from large temperatures, glaciers melting and weakening of sea ice floating around the peninsula on the sea. Researchers are now in a new study
The Southern Ocean is a major repository of carbon dioxide. Nearly half of CO2 absorbed by all the oceans of the world is found in the Southern Ocean. “Understanding how climate change will affect the absorption of carbon dioxide by the Southern Ocean – especially in Antarctic coastal areas such as the Antarctic Peninsula – is crucial to the global impacts of climate change, better predicting, “Research leader Michael Brown says.
The increase in CO2 in seawater has led to ocean acidification in recent years. This is because the balance between absorption and release of A2 in the ocean is interrupted.
As a result, the ocean cannot accommodate the amount of CO2 entering the water, making the ocean sour. Acidification of the sea has a lot of consequences for marine life. For example, scientists estimate that the number of sharks decreased by 44 percent in 2100.
In the study, the research team analyzed measurements in the Southern Ocean conducted between 1993 and 2017.
The researchers found that the amount of algae had increased significantly during this period. Algae take carbon dioxide from the atmosphere and ensure that it is stored deep in the Southern Ocean. In this way, the ocean becomes a more important buffer for carbon dioxide. Researchers found that carbon dioxide intensified nearly five times in summer.
In the southern part of the peninsula – which has been exposed to far less impact of climate change – carbon dioxide was the sharpest.
As climate change continues, it can further disrupt the balance between the rapid release and release of carbon dioxide into the sea. For example, researchers argue that global warming can ensure that sea ice on the Southern Ocean will gradually go away in the coming decades. And it is very alarming. Sea ice is proving to have a big impact on the global carbon cycle.
If the amount of Arctic sea ice decreases further, it could mean that Co2 is extracted from the atmosphere and the concentration of Co2 in the atmosphere increases thus. And that will lead to higher temperatures, which could melt even more sea ice.
Researchers warn that if the ocean absorbs less carbon dioxide it can lead to more warming worldwide. This is because more CO2 environments will stay. According to the researchers, it is therefore important to keep a close watch on the sea around the Antarctic Peninsula.
