The carbon cycle: Better understanding carbon-climate feedbacks and reducing future risks

Climate change and the carbon cycle 1.1 Why the carbon cycle matters 1.2 The natural carbon cycle For 800,000 years The processes of the carbon cycle are The Earth has an active natural carbon until the Industrial fundamentally tied to the climate of our cycle, inhaling and exhaling carbon like a planet. [...] The cumulative amount of emissions is more important than annual emissions in determining Monitoring the carbon sinks through the level of climate change because CO2 observation, in addition to modelling the molecules stay in the atmosphere for a long time carbon cycle to test understanding of the (16 – 34% of CO2 will stay in the atmosphere processes, will be particularly important. [...] Opportunities for research progress 2.1 Understanding the future of the carbon This means the dampening effect the sinks A critical concern sinks – knowns and unknowns have played on climate change to-date may is the impact of With both CO2 emissions and concentrations reduce, and greater mitigation action will be at unprecedented levels, the world is in needed to meet the objectives of the Paris. [...] Whereas example by quantifying the risks of carbon knowledge can the fundamentals of the carbon cycle are well release from permafrost, peatlands, and be done through known, critical questions remain over the future tropical forests as well as the implications of continuous dynamics of the carbon cycle as well as the ocean acidification on marine ecosystems monitoring of the magnitude of changes. [...] While Revolution, the climate impacts of fossil fuel science has advanced to demonstrate the burning and land-use change are having principles and operation of the carbon cycle, tangible and widespread impacts on the carbon questions remain over the magnitude and timing cycle, from ocean acidification to widespread of impacts of higher atmospheric CO2 levels, wildfires.
