Hiiliverkossa

Hiiliverkossa, translating to "carbon network" in English, refers to the interconnected system of carbon reservoirs and the processes that move carbon between them. These reservoirs, also known as carbon sinks, include the atmosphere, oceans, land, and living organisms. The exchange of carbon between these reservoirs is a continuous and vital process for Earth's climate and ecosystems.

The main reservoirs are the atmosphere, where carbon exists primarily as carbon dioxide (CO2); the oceans, which absorb a significant amount of atmospheric CO2; terrestrial biosphere, encompassing forests, soils, and vegetation; and fossil fuels, formed over millions of years from organic matter.

The movement of carbon between these reservoirs is driven by various natural processes. Photosynthesis by plants removes CO2 from the atmosphere, incorporating it into organic matter. Respiration by plants, animals, and decomposers releases CO2 back into the atmosphere. The oceans absorb and release CO2 through physical and biological processes. Over geological timescales, processes like sedimentation and volcanic activity also play a role.

Human activities, particularly the burning of fossil fuels and deforestation, have significantly altered the natural hiiliverkossa. These activities release large amounts of CO2 into the atmosphere at a rate faster than natural processes can absorb it, leading to an increase in atmospheric CO2 concentrations and contributing to climate change. Understanding the dynamics of the hiiliverkossa is crucial for addressing global environmental challenges.
