2023年12月11日 · This blog post explains the carbon cycle and how it relates to climate change. The carbon cycle is the process by which carbon is exchanged between the atmosphere, oceans, land, and rocks. The main player in the carbon cycle is CO2, a greenhouse gas that traps heat in the atmosphere leading to global warming.

By understanding how human activities have altered the carbon cycle, we can explain many of the climate and ecosystem changes we are experiencing today, and why this rapid rate of change is largely unprecedented in the Earth’s history. The carbon cycle is an essential part of How the Earth System Works.

2020年2月20日 · Over the past 50 years, a growing wealth of long-term atmosphere, ocean, and ecosystem observations has provided essential insights into how climate change affects the ways that carbon moves...

2024年11月6日 · Understanding the carbon cycle and carbon chemistry is crucial for understanding climate change's causes and impacts and developing strategies to mitigate and adapt to its effects.

2019年2月1日 · Changes to the carbon cycle. Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.

Excess carbon in the atmosphere warms the planet and helps plants on land grow more. Excess carbon in the ocean makes the water more acidic, putting marine life in danger. It is significant that so much carbon dioxide stays in the atmosphere because CO 2 is the most important gas for controlling Earth’s temperature.

Study of the carbon cycle is critical to narrow gaps in our understanding of the Earth system and more accurately project the efect of CO2 emissions on global temperatures. While the fundamental processes driving flows of carbon are largely known, uncertainties remain, particularly in the magnitude of change.

Includes new chapters on dynamic properties of the global carbon cycle, climate models and projections, and managing carbon in the global biogeochemical cycle. Key Features Addresses the scientific principles governing carbon fluxes at successive hierarchical levels of organization, from cells to the biosphere

Key processes are the atmospheric lifetimes of CO2 and other greenhouse gases, terrestrial net ecosystem production, and the biological and carbonate pumps in the ocean. Models of the global carbon cycle have to reflect both positive and negative feedbacks along these pathways.

Understanding the mechanisms driving interannual variability in the carbon cycle has the potential to provide insights into whether and to what extent the carbon cycle can affect the climate (carbon–climate feedback), with particular interests over the highly climate-sensitive tropical carbon cycle (e.g., Cox et al., 2013; X. Wang et al ...
