Why British Columbia needs to Turn Down the Heat:Climate Change & B.C., Canada:A World Bank Coursera Final Project
+Outline
Introduction: The World Bank’s “Turn Down the Heat” Report British Columbia, Canada
Negative effects: Environmental effects Economic effects Health effects
Implications Conclusion
+Introduction: World Bank Report World Bank Report “Turn Down the
Heat”: Must avoid a 4 degrees C increase in
global temperatures to avoid irreversible climate change
The frequency/severity of floods, droughts, storms, and other natural disasters are predicted to rise
These events will have untold global effects on the environment
Climate change will effect key industries, services & infrastructure

+Introduction: B.C., Canada
Location: Westernmost province of Canada Known for its natural beauty and diverse ecosystems However, Climate change is already affecting Canada!
Canadian insurance companies: payouts have doubled every five years (since 1983) due to: Property damage Infrastructure damage More sickness Higher mortality

+Environmental effects: Rising temperatures By 2050:
Greater Vancouver: Will have average temperature of Northern California
Prince George Area: Okanagan weather
By 2080: Projections of further
warming of 0.9-1.8 degrees C
+Environmental effects:Milder winters & drier summers B.C. lost 50% of snow pack in last 50-100 years
Less snow runoff in summer less water for crops less water for hydropower/industries
Annual precipitation increased 20% Spread of outbreaks (due to mild winters)
Blue Stain Fungus Spread by Mountain Pine Beetle Affected area = 4 Vancouver Islands (13 million ha) Range could expand north & east
More severe fires/droughts
+Environmental Effects:The Mountain Pine Beetle Epidemic

+Environmental Impacts:What happened to the snow?

+Environmental effects:Floods & Rising sea levels Changing rain/snow patterns: affects rivers, lakes, groundwater B.C. glaciers have steadily been retreating Faster melts/increased precipitation
Floods in Fraser Valley, Interior regions and other areas in B.C.
Low lying areas hit hardest (ie: Delta) Higher flood risk due to storms
Sea Level Rise: 4-12 cm along most of the coast Up to 16-34cm in Vancouver area over past century By 2050
Northern B.C. coast: up to 30cm Northern Yukon: up to 50cm
+Environmental effects:Sea Level Rise in the Lower Mainland

+Environmental effects: Species’ adaptation Forests: What trees will adapt to 2050 climate?
Forests need 40-50 years to establish Trees can’t move as fast as climate
North shore mountains Dying of stress Summer drought/Winter storms
Western Red Cedar Iconic First Nations symbol May migrate to Northeastern B.C. (to Fort Nelson) May get taken over by early successional pine
(vulnerable to beetle)
Pacific Northwest: Could lose 47% of plant species What species will take over?

+Economic Effects: Forest & Fisheries Large amounts of timber lost due to
fire & mountain pine beetle Fisheries may be affected by
increased glacier melt/warmer waters Acidification of water ways can prevent
shellfish larvae from properly developing shells Zooplankton (with calcium carbonate
shells) are main food source for salmon

+Economic Effects: Agricultural sector Crops damaged by pests and extreme weather Risk of soil salinization
Once soils are salty, nothing can be done
Destroyed crops: 2009: Spotted wing drosophila destroyed cherry crops in
Okanagan 2010: High precipitation destroyed much of the root crops in Delta 2012: Drought in Peace River region
Prince George: Will have Okanagan-type climate (warmer) Will there be enough water?
+Economic effects:Damage to infrastructure Roads
Milder winters More freeze/thaw cycles reduce life of road/maintenance cost
Flooding 2010: Highway to Bella Coola
destroyed (175 residents evacuated)
Buildings By 2050, 2000-3000 homes at risk of
floods At a cost of $2000/annum per resident
by 2050s Fire season of 2003
Destroyed 334 homes, 45,000 evacuated
Fire off Highway 20 (BC, Canada)

+Health Effects:
Air Quality: 2010 fire season: air quality warnings issued by City of Vancouver and
Government of Alberta
Stroke/Respiratory illness: Due to heat waves 2009: 8 day heat wave in lower mainland
Vancouver Coastal Health Authorities reported more deaths compared with average
More outbreaks: Cryptococcus gattii fungus (caused by milder winters)
Since 1999: 129 infections, 4 deaths on Vancouver Island
Psychological impacts: Due to evacuation from floods/fires
+Implications: What needs to be done? Agricultural sector:
Take advantage of improved agricultural systems (Northern B.C.) produce more food to support a growing population
Need improved irrigation systems to combat water shortages Natural methods to eliminate crop pests/diseases Reduce dependency on US imports
California current accounts for the majority of fruit & vegetable imports to B.C. but agriculture sector now in crisis due to water shortages
Forestry sector: Improve market for blue fungus stained timber destroyed by mountain pine
beetle Reforest based on future forest structure projections
Fisheries sector: Improve the fish farming industry Adapt market for changing fish stocks due to changing water system
conditions
+Implications:What needs to be done? Reduce carbon footprint
Expand clean, public transportation Promote energy saving measures
Invest in renewables Reduce dependency on hydroelectric power Avoid turning to fossil fuels to supplement energy demand
Improve infrastructure: Better flood mitigation Improved road systems
+Conclusion: Major action needs to be taken
International agreements (COP21 in Paris) By national, provincial, and municipal
governments Communities need to work together to find
feasible, sustainable solutions
New initiatives with future conditions in mind: A larger population Fewer resources More natural disturbances
