IPCC Fifth Assessment Report 
IPCC AR5 Synthesis Report 
Synthesis Report
The IPCC Synthesis Report 
➜ Integration of three Working Group Reports of 
the 5th Assessment, 2013-2014 
• WG I : The Physical Science Basis 
• WGII: Impacts, Adaptation and Vulnerability 
• WG III: Mitigation of Climate Change 
IPCC AR5 Synthesis Report
The IPCC Synthesis Report 
➜ Written by 60 authors from Working Group reports 
➜ Chaired by the IPCC Chair R.K. Pachauri 
➜ Member governments approved the SPM on 1st 
November 2014 (total membership of IPCC is 195 
governments) 
IPCC AR5 Synthesis Report
Key Messages 
➜ Human influence on the climate system is clear 
➜ The more we disrupt our climate, the more we 
risk severe, pervasive and irreversible impacts 
➜ We have the means to limit climate change and 
build a more prosperous, sustainable future 
IPCC AR5 Synthesis Report 
AR5 WGI SPM, AR5 WGII SPM, AR5 WGIII SPM
Humans are changing the climate 
It is extremely likely that we are the dominant cause of warming 
since the mid-20th century

➜ More than 90% of the 
energy accumulating 
in the climate system 
between 1971 and 
2010 has 
accumulated in the

Impacts are already underway 
• Tropics to the poles 
• On all continents and in the ocean 
• Affecting rich and poor countries 
IPCC AR5 Synthesis Report

Projected climate changes 
Continued emissions of greenhouse gases will cause further 
warming and changes in the climate system 
Oceans will continue to warm 
during the 21st century 
IPCC AR5 Synthesis Report 
Global mean sea level will 
continue to rise during the 
21st century 
Global glacier volume will 
further decrease 
It is very likely that the Arctic sea 
ice cover will continue to shrink 
and thin as global mean surface 
temperature rises

A reader’s guide 
From climate change 
risks to GHG emissions
The risks from climate 
change, assessed by the 
WGII of the IPCC AR5, and 
aggregated in five “Reasons 
for Concerns” 
Levels of risk across the Reasons 
for Concern can be associated with 
a level of global temperature 
change. 
Here shown for a warming by 2oC
The link between cumulative CO2 emissions 
and global mean temperature 
The pink plume is from WGI complex models. 
It includes the uncertainty from non-CO2 gases and 
climate and carbon cycle uncertainty, using the likely 
range
The link between cumulative CO2 emissions 
and global mean temperature 
The ellipses show results from the WGIII models, 
using a simple climate model. It does not include 
climate and carbon cycle uncertainty, but explores 
more comprehensively the scenario uncertainty from 
a range of CO2 and non-CO2 pathways
Levels of risks can be connected to cumulative 
CO2 emission levels, for the average climate 
response, for high climate sensitivity (lower 
cumulative emissions), and for low climate 
sensitivity (higher cumulative emissions)
The link between changes in 
annual GHG emissions by 2050 
and the cumulative CO2 
emissions of the WGIII scenario 
categories
Levels of risks can now be 
connected to GHG emission 
changes by 2050. Added 
uncertainty arises from action on 
non-CO2 gases, timing of pre-2050 
action, and ambition of post-2050 
action.
The constraint on changes in GHG 
emissions by 2050 depends on the 
sensitivity of the climate response. 
Here, with large climate sensitivity
The constraint on changes in GHG 
emissions by 2050 depends on the 
sensitivity of the climate response. 
Here, with low climate sensitivity
Limiting Temperature Increase to 2˚C 
Measures exist to achieve the substantial emissions reductions 
required to limit likely warming to 2°C (40-70% reduction in GHGs 
globally by 2050 and near zero GHGs in 2100) 
A combination of adaptation and substantial, sustained reductions in 
greenhouse gas emissions can limit climate change risks 
Implementing reductions in greenhouse gas emissions poses 
substantial technological, economic, social, and institutional 
challenges 
But delaying mitigation will substantially increase the 
challenges associated with limiting warming to 2°C 
IPCC AR5 Synthesis Report 
AR5 WGI SPM, AR5 WGII SPM,AR5 WGIII SPM
Mitigation Measures 
More efficient use of energy 
Greater use of low-carbon and no-carbon energy 
• Many of these technologies exist today 
Improved carbon sinks 
• Reduced deforestation and improved forest management 
IPCC AR5 Synthesis Report 
and planting of new forests 
• Bio-energy with carbon capture and storage 
Lifestyle and behavioural changes 
AR5 WGIII SPM
Ambitious Mitigation Is Affordable 
➜ Economic growth reduced by ~ 0.06% 
(BAU growth 1.6 - 3%) 
➜ This translates into delayed and not forgone 
growth 
➜ Estimated cost does not account for the 
benefits of reduced climate change 
➜ Unmitigated climate change would create 
increasing risks to economic growth

  • 21. Figure SPM.10, A reader’s guide From climate change risks to GHG emissions
  • 22. The risks from climate change, assessed by the WGII of the IPCC AR5, and aggregated in five “Reasons for Concerns” Levels of risk across the Reasons for Concern can be associated with a level of global temperature change. Here shown for a warming by 2oC
  • 23. The link between cumulative CO2 emissions and global mean temperature The pink plume is from WGI complex models. It includes the uncertainty from non-CO2 gases and climate and carbon cycle uncertainty, using the likely range
  • 24. The link between cumulative CO2 emissions and global mean temperature The ellipses show results from the WGIII models, using a simple climate model. It does not include climate and carbon cycle uncertainty, but explores more comprehensively the scenario uncertainty from a range of CO2 and non-CO2 pathways
  • 25. Levels of risks can be connected to cumulative CO2 emission levels, for the average climate response, for high climate sensitivity (lower cumulative emissions), and for low climate sensitivity (higher cumulative emissions)
  • 26. The link between changes in annual GHG emissions by 2050 and the cumulative CO2 emissions of the WGIII scenario categories
  • 27. Levels of risks can now be connected to GHG emission changes by 2050. Added uncertainty arises from action on non-CO2 gases, timing of pre-2050 action, and ambition of post-2050 action.
  • 28. The constraint on changes in GHG emissions by 2050 depends on the sensitivity of the climate response. Here, with large climate sensitivity
  • 29. The constraint on changes in GHG emissions by 2050 depends on the sensitivity of the climate response. Here, with low climate sensitivity
  • 30. Limiting Temperature Increase to 2˚C Measures exist to achieve the substantial emissions reductions required to limit likely warming to 2°C (40-70% reduction in GHGs globally by 2050 and near zero GHGs in 2100) A combination of adaptation and substantial, sustained reductions in greenhouse gas emissions can limit climate change risks Implementing reductions in greenhouse gas emissions poses substantial technological, economic, social, and institutional challenges But delaying mitigation will substantially increase the challenges associated with limiting warming to 2°C IPCC AR5 Synthesis Report AR5 WGI SPM, AR5 WGII SPM,AR5 WGIII SPM
  • 31. Mitigation Measures More efficient use of energy Greater use of low-carbon and no-carbon energy • Many of these technologies exist today Improved carbon sinks • Reduced deforestation and improved forest management IPCC AR5 Synthesis Report and planting of new forests • Bio-energy with carbon capture and storage Lifestyle and behavioural changes AR5 WGIII SPM
  • 32. Ambitious Mitigation Is Affordable ➜ Economic growth reduced by ~ 0.06% (BAU growth 1.6 - 3%) ➜ This translates into delayed and not forgone growth ➜ Estimated cost does not account for the benefits of reduced climate change ➜ Unmitigated climate change would create increasing risks to economic growth IPCC AR5 Synthesis Report AR5 WGI SPM, AR5 WGII SPM
