Weather versus Climate Weather describes current and near-term conditions Climate describes weather patterns over a longer term “Weather is what you get; climate is what you expect.”
Human or natural causes of climate change? National Climate Assessment, 2014 Models can reproduce the climate with and without added CO2
Measuring climate change National Climate Assessment, 2014 These indicators are embedded into global climate models 6 6
Temperature and Precipitation Increase in hot days and heatwaves • Potential impacts: human health, crops, species and ecosystems (e.g. forest fires) Droughts, floods and extreme rainfall • Potential impacts: Landslides, crops destroyed, dams affected
Global sea levels are increasing Source: IPCC AR5 Summary for Policymakers https://www.ipcc.ch/pdf/assessment- report/ar5/wg1/WG1AR5_SPM_FINAL.pdf • Global sea level rose by 0.19 meters over the period 1901 to 2010. • The rate of sea level rise has increased over the 20th century: - 1.7 mm/year between 1901 and 2010 - 2.0 mm/year between 1971 and 2010 - 3.2 mm/year between 1993 and 2010
Storm surge and sea level rise Storm surge is an abnormal rise of Storm Surge vs. Storm Tide water generated by a storm, over and above the normal astronomical tides and wave conditions Storm tide is the water level rise due to the combination of storm surge and the astronomical tide Higher sea levels will allow storm surges from storms of similar strength to reach further inland and cause more destruction to life and property.

Outcome: Integrated and effective climate change response STRATEGIC DEVELOPMENT & GOVERNANCE IMPLEMENTATION RESEARCH Council/ EXCO/ standing political committees: National Policy: NDP, Climate Bill Local Policy: IDP, SDF, city strategy Strategic Management EM Climate Change DCCS: to be reviewed by 2020 Forum: administrative Committee: political oversight of DCCS oversight of DCCS implementation implementation Project implementation: Municipal Adaptation Plans, C40 DCCS Integrated Implementation Chair: DCCS TTT Deadline 2020, Sihlanzimvelo, Plan: to be developed by mid 2019 DCCS Technical Task Team: dashboard Climate Resilience DMAF review and coordination of implementation Implementation Plan, METIS, M&E Framework and reporting of DCCS between line functions; reporting to GHG reporting etc. tool: to be developed by mid 2019 EM CCC A number of these projects have their own steering committees. DCCS Sub-Committee: implementation of DCCS through DCCS dashboard; reporting to DCCS TTT Research DCCS Secretariat: support for the TTT and sub- committee, management of M&E and Research, • To international platforms to advise IPCC global stock take liaison with political committee secretariat and • To national platform to fulfil nationally determined feedback to DMAF contributions within UNFCCC • Into municipal platforms to inform SDBIP/ Scorecard Service provider: support for DCCS Secretariat and development of implementation plan
Development of the fully integrated DCCS Implementation Plans • Full tender appointment (36 month contract) o Develop a fully integrated mitigation and adaptation set of implementation plans for the DCCS. o Develop monitoring and evaluation framework and reporting tool for the DCCS. o Complete first full review of the DCCS to be inline with Paris Agreement and Climate Change Bill. o Incorporate C40 Deadline 2020 project outcomes into the DCCS review (to put Durban onto a 1.5°C pathway. o Facilitate coordination between municipal line functions. o Mainstreaming and implementation of the DCCS impmementation plan.
Legal Mandate • Existing: – Paris Climate Agreement – adaptation and mitigation – National Climate Change Response Policy – Disaster Management Amendment Act (2015) • Forthcoming: – Climate Change Bill (within NEMA) • Carbon tax • Spatial planning framework opportunities?
