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
Shrinking Glaciers Athabasca Glacier
15
More powerful storms Hurricane Sandy 2012
16
More frequent flooding Calgary 2013 Melville 2014 Image:Government of Saskatchewan
17
Longer droughts California 2014 Image: Janet Davidson CBC News
18
More forest fires
19
More, hotter, heat waves Russia 2010 Canada 2012
20
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 Climate Change in Saskatchewan
21
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 and food borne illnesses Climate Change and Health
22
CO 2 = Carbon Dioxide N 2 O = Nitrous Oxide CH 4 = Methane CO 2 N2ON2O CH 4 CO 2 + N 2 O + CH 4 = CO 2 equivalent
23
Carbon Dioxide (CO 2 ) 100 years!
24
Nitrous Oxide (N 2 O) 114 years!
25
Methane (CH 4 ) 12 years!
26
Saskatchewan GHG Emissions Source: Environment Canada National Inventory Report, 1990-2012
27
SaskPower 2013 Gross Electrical Energy Supplied Electricity Generation
28
World level of CO 2 1870 = 290 ppm World level of CO 2 2013 = 396 ppm How fast is Saskatchewan emitting CO 2 ? 1990 = 44 million tonnes/yr 2011 = 74 million tonnes/yr If Saskatchewan were a country, we would have the second highest per capita GHG emissions in the world.
29
