Climate change is defined as a change in global or regional climate patterns, particularly a change apparent from the mid to late 20th century onward that is attributed largely to increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. Some causes of climate change are biotic processes, variations in solar radiation, plate tectonics, volcanic eruptions, and certain human activities. Those affected by climate change include farmers, fishers, foresters, residents, visitors, and commerce. Observable impacts of climate change include increased temperatures, reduced snowpack, rising sea levels, and more frequent extreme weather events. Adaptation, emission reduction, and community engagement are ways to manage climate change.

2. WHAT IS CLIMATE CHANGE ?
• IT IS A CHANGE IN GLOBAL OR REGIONAL CLIMATE PATTERNS.
• IN PARTICULAR A CHANGE APPARENT FROM THE MID TO THE LATE
20TH CENTURY ONWARDS
• ATTRIBUTED LARGELY TO THE INCREASED LEVELS OF ATMOSPHERIC
CARBON DIOXIDE PRODUCED BY THE USE OF FOSSIL FUELS

3. CAUSES OF CLIMATE CHANGE
• CAUSED BY FACTORS SUCH AS: BIOTIC PROCESSES, VARIATION IN
SOLAR RADIATION RECEIVED BY EARTH
• ALSO THE PLATE TECTONICS AND VOLCANIC ERUPTIONS CAUSE THE
CLIMATE CHANGE.
• CERTAIN HUMAN ACTIVITIES HAVE BEEN IDENTIFIED AS PRIMARY
CAUSES OF ONGOING CLIMATE CHANGE.

4. WHO IS AFFECTED BY CLIMATE CHANGE?
• FARMERS
• FISHERS
• FORESTERS
• NEW BRUNSWICKERS
• VISITORS
• COMMERCE

5. THE DIAGRAM THAT SHOWS THE
ATMOSPHERE

6. GREENHOUSE GASES
• ARE THE GASES THAT CONTRIBUTES TO THE GREENHOUSE EFFECTS
BY ABSORBING INFRARED RADIATION.
• CARBON DIOXIDE AND CHLOROFLUOROCARBONS ARE EXAMPLES OF
GREENHOUSE GASES

7. GREENHOUSE GASES EMISSION
New Brunswick Greenhouse Gas Emissions
(2004)
Others
Nitrous oxide
3%
Methane
6%
Carbon dioxide
91%

8. CLIMATIC OBSERVATION
• TEMPERATURE- UP 0.7 DEGREES
• SNOW PACK- DOWN 25% (NORTH) AND 50% (SOUTH)
• SEA LEVEL RISE- UP 30 CM
• EXTREME STORM EVENTS- 5 TIMES AS FREQUENT

9. HOW CAN WE MANAGE CLIMATE CHANGE?
• EMISSION REDUCTION
• ADAPTATION,
• COMMUNITY ENGAGEMENT.

10. ADAPTATION
• ALREADY IMPACTING COMMUNITIES AND COMMERCE
• SEASONAL UNCERTAINTIES
• WATER CONCERNS
• HABITAT AND ECOSYSTEM CHANGES
• HEALTH AND PUBLIC SAFETY
• RESOURCES INDUSTRY SECTORS IMPACTED

11. COMMUNITY ENGAGEMENT
• EDUCATION/ AWARENESS ABOUT THIS CLIMATIC CONDITIONS
