8 Observations 8

9 Global Observations The Air 10 warmest years in 134-year record have happened since C increase over preindustrial temperatures Record high temperature events increasing Increasing numbers of intense rainfall events 9

10 Global Observations The Sea Sea level +17 cm (6.7 ) in past century Ocean stores ~90% of additional heat in climate system Top 700 m C since 1969 Acidity +30% since beginning of industrial revolution 10

11 Global Observations The Ice Greenland -285 B tonnes/year Antarctica -135 B tonnes/year Glaciers retreating globally -400 B tonnes/year Arctic sea ice declined rapidly since 1979 Spring snow cover extent has decreased Snow melting earlier Less of it to melt 11

18 Projections and Impacts 18

19 Climate Projections Globally Robust Results CBC News IPCC AR5 Fig 12.5 NASA More uncertainty: Specific regional and local impacts 19

20 Climate Projections North America CURRENT PATH C Add segment and caption if required. 20 IPCC AR5 WG2 (Regional) Fig 26-3

21 Climate Projections North America % 21 IPCC AR5 WG2 (Regional) Fig 26-3

22 Climate Projections NL in General Warmer temperatures year round Greater increases in winter and north/west/inland Increased agricultural potential Less frost events on shoulder seasons More growing degree days Increased precipitation Average annual accumulation More intense extremes Sea level rise Significant for the island, not so much for the Big Land 22

23 Climate Projections Extremes in NL Summer Extreme Hot RCP Extreme Precipitation RCP IPCC AR5 WG2 (Regional) Fig 26-4

24 Climate Projections Extremes in NL Summer Extreme Dry RCP March Extreme Low Snow RCP IPCC AR5 WG2 (Regional) Fig 26-4

25 Adaptation and Resilience 25

26 Adaptation and Resilience Successful adaptation does not mean that negative impacts will not occur, only that they will be less severe than would be experienced had no adaptation occurred. - Natural Resources Canada Resilience is the capacity of individuals, communities, institutions, businesses, and systems within a society to survive, adapt, and grow no matter what kinds of chronic stresses and acute shocks they experience. - Adapted from 100 Resilient Cities Be Prepared! 26

27 Adaptation and Resilience Status quo no longer sufficient! Can no longer base designs, regulations, governance, etc on the historical record Reduce negative impacts Higher capacity culverts Reinforce/relocate coastal infrastructure Take advantage of the positive impacts Increase agriculture Plan for lower snow clearing and heating needs 27

28 Identify Key Systems and Infrastructure Healthcare Commercial buildings Education Homes and cabins Offshore industry Food security Water resources Fishery Energy security Tourism Recreation Agriculture Ocean transportation Land transportation 28

29 Vulnerability Risk Assessments Direct where adaptation efforts should focus What are the sensitive sectors? What is the current adaptive capacity? Risk = Consequences + Likelihood Free Adaptation Tools and Resources NL s 7 Steps to Assess Climate Change Vulnerability in Your Community Engineers Canada s PIEVC Protocol Federation of Canadian Municipalities Help develop an Action Plan 29

30 Action Plan Components Land use planning Infrastructure upgrades Community services & engagement Licensing and regulation Workforce development Adapted from Federation of Canadian Municipalities Changing Climate, Changing Communities: Guide for Municipal Climate Adaptation 30

31 Roads Snow clearing and ice control Bridge and culvert washouts Potholes freeze/thaw Amec Foster Wheeler Road Weather Information System Thorburn Rd Freeze- Thaw Cycles ( ) Air (2 m) 225 Surface Sub (6 cm)

32 Healthcare Increased heat stress Pests and invasive species Infrastructure vulnerabilities 32

33 Food Security Increased agricultural potential Food import challenges Long supply chains Droughts and conflicts Ports and ocean transportation Storm surge > sea level rise 33

34 Offshore Industry More severe storms Altered wind regimes Sea ice risks Iceberg risks 34

35 Challenges Awareness of climate change impacts Accepting the need to adapt Awareness of available tools and resources Making long term a priority Near term costs 35

36 Opportunities Awareness is increasing Replacing aging infrastructure Take advantage of positive impacts More than most places! Develop diverse industry 36
