1. Energy, Greenhouse Gas Emissions, and Climate Change

11. “Warming of the climate system is unequivocal (leaving no doubt)”
Intergovernmental Panel on Climate Change
(IPCC) 2013

12. “Human influence on the climate system is clear.”
IPCC 2013

13. Weather is what it’s like out today, or this week, or even this year
Climate is the pattern of weather over years

14. What to expect
Currently on track for 3-5oC global average temperature increase by IPCC 2013
Last ice age, the global average temperature was 5oC lower than current.
Warming will be more extreme nearer the poles.

15. Shrinking Glaciers
Athabasca Glacier

16. Texas 2017
More powerful storms
Hurricane Sandy 2012

17. More frequent flooding
Calgary 2013
More frequent flooding

18. Longer droughts

19. More forest fires
Fort McMurray 2016

20. Canada 2012
More, hotter, heat waves
Russia 2010

21. Reduced winter sports

BC 2015

22. Climate Change in Saskatchewan
more intensive rainfall - causes more frequent and more serious flooding
greater risk of more serious droughts
loss of at least the southern part of the boreal forest
reduced river flows … shrinking glaciers

23. Climate Change and Health
Warmer, wetter weather increases smog production, mould, pollen and fungal spores
Milder winters reduce winter peak deaths
Hotter summers increase summer heat related illnesses and deaths
Increase in vector borne diseases

24. CO2 + N2O + CH4 = CO2 equivalent
CO2 = Carbon Dioxide
N2O = Nitrous Oxide
CO2
CH4 = Methane
N2O
CH4

25. Carbon Dioxide (CO2)
100 years!

26. Nitrous Oxide (N2O)
114 years!

27. Methane (CH4)
12 years!

28. Saskatchewan GHG Emissions

29. Electricity Generation

30. How fast is Saskatchewan emitting CO2 ?
World level of CO2 1870
= 290 ppm
World level of CO2 2017
= 403 ppm
How fast is Saskatchewan emitting CO2 ?
1990 = 44 million tonnes/yr
2015 = 75 million tonnes/yr
If Saskatchewan were a country, we would have the second highest per capita GHG emissions in the world.

31. We have work to do 2014 Saskatoon Greenhouse Gas Emissions Inventory
12% increase since 2003

32. Action Conserve energy Conserve water Reduce waste Eat local
Eat less meat
Increase biodiversity
Use active transportation
