From AR5 to AR6 - Perspectives from Working Group III by Priyadarshi Shukla
- 1. http://bit.ly/ipcc_outreach_cambodia Fifth to Sixth Assessment Cycle: IPCC WG III Perspective P. R. Shukla and Jim Skea, Co-Chairs IPCC WGIII Cambodia, 28 May 2019
- 2. FAR (1990) …IPCC has made an impact led to UNFCCC SAR (1995) input for Kyoto Protocol TAR (2001) focused attention on Impacts of climate change and need for adaptation AR4 (2007) input for Decision on 2ºC limit; basis for post Kyoto Protocol agreement AR5 (2013/2014) input for 2
- 3. Achievements: 2007 Nobel Peace Prize The Intergovernmental Panel onClimate Change andAlbertArnold (Al)Gore Jr.were awarded the Nobel Peace Prize "for their efforts to build up and disseminate greater knowledge about man-made climate change, and tolay the foundations for the measures that are needed to counteract such change". 3
- 4. GHG emissions growth between 2000 and 2010 has been larger than in the previous three decades. (IPCC AR5) AR5 WGIII SPM 4
- 5. 5 Based on SRREN Figure 1.7 There is far more carbon in the ground than emitted in any baseline scenario.
- 6. Stabilization of atmospheric concentrations requires moving away from the baseline – regardless of the mitigation goal. ~3°C Based on Figure 6.7 AR5 WGIII SPM 6
- 7. Mitigation Measures (IPCC AR5) 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 and planting of new forests • Bio-energy with carbon capture and storage Lifestyle and behavioural changes AR5 WGIII SPM 7
- 8. Climate change mitigation can bring co-benefits – health, energy security and other societal goals. 8 Based on Figures SPM.6 and 12.23
- 9. IPCC WGIII AR5: Conclusions GHG emissions growth has accelerated despite reduction efforts. Climate change mitigation is possible for 2 °C target and early action will make it easier Ambitious mitigation involves transformation of the energy system. Climate change mitigation can bring co-benefits 2 °C
- 10. Climate Change and Sustainable Development Goals (SDGs)
- 11. 1) The Special Reports Main Products during the AR6 cycle Special Report on Global Warming of 1.5°C (SR15) Special Report on Climate Change and Land (SRCCL) Special Report on Ocean and Cryosphere (SROCC) Approved October 2018 Approval August 2019 Approval September 2019
- 12. 2) A methodology report (inventories) 3) Three Working Group reports 4) A Synthesis Report Main Products during the AR6 cycle
