"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

• Mitigation scenarios including overshoot & climate intervention
• Potential for rapid change and/or irreversible tipping points in the
Earth system, in ecosystems, and in human systems.
• While various CDR and SRM proposals have potential, neither is a
substitute for emissions cuts, and both raise concerns that cannot be
adequately addressed without much more research.
• Land use: understanding the trade-offs and co-benefits of adaptation
& mitigation options.

20. An evolving CMIP design
A more continuous approach with
small targeted “Fast Track”
experiment sets. The first will
respond to the needs of IPCC
AR7.
CMIP infrastructure, standards
and tools support ongoing science
and assessment activities.
This design reflects extensive
feedback from the modelling
centres and wider user
community.
21. As the utility of CMIP grows we seek a wider range of voices contributing to CMIP
design, organisation and governance.
The CMIP Task Teams support CMIP experimental design and implementation.
Most task teams focus on the infrastructure required for coordinated experiments
(e.g., data request, forcings….). Others address community needs (e.g., data
access....) or overarching scientific issues (strategic ensemble design).
Fresh Eyes on CMIP integrates the voices of ECRs worldwide into CMIP.
An evolving CMIP organisation
21
22. • Scenarios will be a core component of the CMIP
AR7 Fast Track.
• ScenarioMIP are currently developing their
experimental protocol with a first proposal for
stakeholder review expected by end of the year.
• A number of task forces have been established:
low/overshoot scenarios, middle/high scenarios,
extensions, CDR and IAM-ESM interactions.
More information at ScenarioMIP webpages.
Scenario development
23. High scenario:
• Highest plausible emissions scenario, for risk
assessment and potential adaptation needs
Medium scenario:
• Reflect the implications of current policies with no
further strengthening
Low scenarios:
• 1.5 C, 1.5 C with overshoot, well below 2 C
• Explore scenarios consistent with Paris agreement
goals
More information at ScenarioMIP webpages.
Scenario rationale
24. Emissions-driven simulations
• Resolve carbon cycle and CDR
uncertainties in flagship CMIP7
simulations.
• Define scenarios in terms of activity
pathways (emissions and land use),
rather than concentrations.

• Supported by process-
understanding
experiments
25. • CMIP continues to push the boundaries of
model complexity.
• This means that in addition to emission
driven simulations, models will also include
comprehensive descriptions of aerosols,
interactive ice sheets, methane and
nitrogen.
• Models will be used to explore climate
interventions and to gain further insights
from paleoclimates.
Exploring complexity

26. Exploring resolution
• Internal variability, scenario
choices, resolution and
complexity are all important
dimensions of the uncertainty in
projections.
• Model resolution provides more
regional detail and in CMIP7,
resolution will be explored in
HighResMIP2.
• CMIP will also aim to bridge to
km-scale models.
