C. Climate Information for Risk Assessment and Regional
Adaptation
Physical climate information addresses how the climate system responds to the interplay
between human influence, natural drivers and internal variability.
Knowledge of the climate response and the range of possible outcomes, including low-
likelihood, high impact outcomes, informs climate services, the assessment of climate-
related risks, and adaptation planning.
Physical climate information at global, regional and local scales is developed from multiple
lines of evidence, including observational products, climate model outputs and tailored
diagnostics.
6. Climate Information for Decision Makers
IPCC AR6 WGI FAQ 10.1 Figure 1
• The distillation of regional climate information from
multiple lines of evidence
✔ The distillation process can draw upon multiple observational
datasets, ensembles of different model types, process
understanding, expert judgement and indigenous knowledge.
✔ Important elements of distillation include attribution studies, the
characterization of possible outcomes associated with internal
variability and a comprehensive assessment of observational,
model and forcing uncertainties and possible contradictions
using different analysis methods.
• The distillation of regional climate information taking
the user context into account
✔ Taking the values of the relevant actors into account when co-
producing climate information, and translating this information
into the broader user context, improves the usefulness, fitness
and uptake of this information.
7. Climate Information for Decision Makers

Advances in identifying drivers for the near-term (2021-2040) climate changes

regional scales and in the near term, with little effect on centennial global warming.

AR6 WGI SPM D1.7: In the five illustrative scenarios, simultaneous changes in CH4, aerosol and ozone
precursor emissions, which also contribute to air pollution, lead to a net global surface warming
in the near and long term (high confidence).
10. Advances in identifying sources of uncertainties in near-term information
Large uncertainties in near-term (2021-2040) information
due to
o Internal variability: Single-model initial-condition large
ensembles and storylines approach provide a more
comprehensive spectrum of possible changes associated with
internal variability
o Model uncertainty: Scenario-based projections for global
surface temperature are better constrained based on past
warming simulations
o Uncertainties in forcings from natural and anthropogenic
aerosols: The climate impacts from potential large volcanic
eruptions are better understood.

multiple lines of evidence.

Global surface temperature change from 1950 to 2100 relative to 1850-1900

The central estimate of crossing the 1.5oC
global warming level lies in the early 2030s

AR6 WGI Figure SPM.8; Chapter 4
AR6 WGI Chapter 4: By 2030, global surface temperature in any individual year could exceed 1.5oC relative to 1850-
1900 with a likelihood between 40% and 60%, across the scenarios considered (medium
confidence).
The threshold-crossing time is defined as the midpoint of the
first 20-year period during which the average global surface
temperature exceeds the threshold

13. Better constraints are needed for other climate variables and regional changes

September Arctic sea ice area Global surface ocean pH
AR6 WGI Chapter 4: The part of the climate system that have shown clear increasing or decreasing trends in recent
decades will continue these trends for at least the next twenty years. However, over a period as
short as twenty years, these trends are substantially influenced by natural climate variability,
which can either amplify or attenuate the trend expected from the future increase in greenhouse
gas concentrations.
14. Global Warming Levels (GWLs) are used to assess global and regional
climate change, linking to scenarios

o With every increment of global warming, changes in regional mean temperature, precipitation,
and soil moisture and changes in extremes and climatic impact-drivers get larger.
15. Summary and Discussion
• Linking climate change information to impact and risk assessments in the AR6
• Methodological improvement for the linkage between WGI and WGII
• Climatic Impact-Drivers (mean, events, and extremes) as a handshake to WGII
• Advances in near-term climate information in the AR6 WGI
• Improvement in projection of the near-term evolution of the climate system
• Improvement in identifying drivers
• Improvement in identifying sources of uncertainties
• Improvement in methodology for better climate information based on multiple lines
of evidence
• More dedicated researches are needed to Improve our understanding and prediction/
projection of near-term climate change, especially at regional and local scales to better
inform decision makers. The WCRP Lighthouse activities will facilitate the further
improvement.

all over the world
92. These play a key role
in shaping extreme
events and hazards
Yet capabilities for
quantitative explanation
and prediction of
changes on multi-
annual timescales are
limited
NOAA
93. Explaining and Predicting
Earth System Change
Overarching Objective:
an integrated capability for quantitative observation, explanation, early
warning and prediction of Earth System Change
on global and regional scales and annual to decadal (A2D) timescales
We need these capabilities
and knowledge
to inform adaptation and
improve resilience
94. Theme 1:
Monitoring and Modeling Earth System Change
We seek tighter integration of
models and observations to
monitor and understand Earth
system change
● How can we address persistent biases in
model simulations?
● How can we address under-utilization of
diverse observational data?
● Which enhanced observations will offer the
greatest improvements in predictive and
explanatory skill? Where should those
enhancements be targeted?
95. Theme 2:
Integrated Attribution, Prediction and Projection
We seek to identify and attribute
the primary drivers of Earth
system change on A2D scales
(e.g., anthropogenic vs internal
sources of variability)
● Advocate for the generation of large
ensembles of single-forcing experiments
● The goal: to integrate attribution and
prediction capabilities to provide
seamless information for decision
making
96. Theme 3:
Assessment of Current and Future Hazards
We seek to understand how
internal variability and external
forcings influence the
characteristics and occurrence of
meteorological hazards on A2D
scales in different regions
● Focus on a subset of hazards (e.g.
tropical cyclones, heatwaves, droughts)
● Make use of large ensembles
● The goal: to use observations, models
and process understanding to deliver
robust assessments of current and
future hazards for specific regions and
hazard classes
98. Near-term outputs
(2024 onwards):
• Contributions to WMO State of the Climate and
Global Annual-to-Decadal climate update reports
• Advice to GCOS on observational requirements
for explaining and predicting Earth system change
99. Benefits to Society: • Quantitative process-based explanation of ongoing
and emerging changes in the climate system
• Understanding and quantification of changes in
classes of meteorological hazards on A2D scales
• Improved predictions and early warnings
These efforts will help us integrate attribution
and prediction capabilities to provide
seamless information for decision making for
near-term climate needs

102. Managing climate
risks & opportunities
• Scientifically credible and accessible climate information,
products and services are important elements in the decision-
making
• Generate climate information of high quality across timescales
• Operationalizing climate information services requires
standards and a well-coordinated end-to-end institutional
systems
• Agile and inclusive approaches are required to engage diverse
communities at different scales (global, regional, national,
local)
• Translate research into operational services
