The little-known role of the ocean is to regulate the ocean through the ocean. CO2 absorption (CO2), explained United Nations Educational, Scientific and Cultural Organization (UNESCO) also warned that if the ocean loses this function, the ocean will exacerbate global warming, thereby accelerating the process of climate change.
To prevent this from happening, the report says that this is Emergency research absorption cycle Know about carbon dioxide, and fully understand and develop a roadmap to guide the authorities responsible for designing climate change mitigation and adaptation policies in the next ten years.
The text emphasizes the importance of scientific knowledge for making informed decisions in the United Nations Framework Convention on Climate Change in order to achieve the climate goals of the Paris Agreement and build a more resilient society.
Anthropogenic carbon pool
Since the industrial revolution, the ocean has been a reservoir of carbon Produced by human activities. Without these marine and terrestrial reservoirs, the CO2 content in the atmosphere would be 50% higher than the record in 2019, and the record in 2019 has far exceeded the limit of controlling global warming at 2 degrees Celsius.
The global carbon cycle is an indispensable part of the earth system. In the terrestrial, atmospheric and oceanic components of the global carbon cycle, they exchange carbon on time scales ranging from decades to centuries, and the carbon contained in these reservoirs in the ocean exceeds 90%. Since the beginning of the Industrial Revolution in the late 18th century, Humans have greatly changed carbon storage and flux In the land-atmosphere-ocean system, fossil carbon in geological reservoirs is used.
Over time, the ocean has changed from a terrestrial biosphere to a pre-industrial carbon sink through rivers, and has become an important annual net carbon sink by absorbing anthropogenic carbon.
The accumulation of carbon generated by human activities in the ocean is Change the chemistry of sea waterThis phenomenon is called ocean acidification. These changes will affect the future role of the ocean as a reservoir of atmospheric CO2 and change the marine ecosystem in ways that are still being studied.
