Important Definitions Weather Climate Climate Change Global Warming
Define: Weather Weather: conditions of the day
Define: Climate Climate: description of an areas average weather and how weather varies over long time intervals
Define: Climate Change Climate change: significant and persistent change in an areas average climate conditions or extremes Local Regional National Global
Define: Global Warming Global warming: an increase in the average temperature of the world A measure of climate change Photo Credit: Philip Martin
What Causes Climate Change Greenhouse gases (GHG) CO2 Others Greenhouse effect Environment Canada 2013
Greenhouse Gases Five GHG occur naturally in the atmosphere A few GHGs are GOOD! More GHGs are BAD!
Greenhouse Effect GHG provide important insulation to the earth GHG act like an insulating blanket keeping earth warm enough for people, plants and animals to survive Thin blanket of GHG
Greenhouse Effect Too many GHG act like a blanket that is too thick The earth over heats! Thick blanket of GHG

So what does this mean?
Impacts on Weather Extreme weather Droughts Flooding Storms Fires
Impacts on AB Nature Shifts in distribution of plants, birds and mammals Earlier plant leafing and flowering Photo Credit: The Gazette, Hunter McRae
Impacts on AB Water Longer ice-free periods on lakes Melting of permafrost Retreating glaciers Less water in summer Photo Credit: psiee.psu.edu
Impacts on AB Water Decreasing water levels Declines in lakes, rivers and muskeg Decreases in drinking water availability
Impacts on AB Soil Increasing ground temperatures Decreasing availability of moisture Photo Credit: cicadablog.saltthesandbox.org
Impacts on AB First Nations Changes in availability to traditional foods and medicines
Impacts on AB First Nations Declines in duration of ice on lakes may affect: Travel Availability of fish
Impacts on AB First Nations Fire Flooding Decreased water availability Etc.
Positive Impacts Longer growing seasons Warmer growing seasons

Summary Increase temperatures Increase water stress More extreme weather events Longer growing seasons Affect First Nations
Thank you for listening! Good News! At the current rate of climate change we will be able to just swim over and eat him in under five years!
