 When discussing the issue of climate change the terms mitigation and adaptation are used frequently.

Climate change mitigation refers to the promotion of policy, regulatory and project-based measures that contribute to the stabilization or reduction of greenhouse gas concentrations in the atmosphere. Renewable energy programs, energy efficiency frameworks and the substitution of fossil fuels are examples of climate change mitigation measures.

The town has been taking inventory of our greenhouse gas emissions and has implemented the following climate change mitigation programs:

  • Partners for Climate Protection Program 
  • Corporate Sustainability 
  • Energy Conservation and Green Energy Programs 
  • Land 
  • Air 
  • Water 
  • Wildlife and Biodiversity 
  • Monitoring and Indicators
  • Environmental Stewardship

Climate change adaptation includes any initiatives or actions in response to actual or projected climate change impacts that reduce the effects of climate change on built, natural and social systems.

Preparing for climate change adaptation does not negate the need to support and implement mitigation measures, it is just another method of dealing with the climatic change impacts. For detailed information on actions you and the town can take to increase our resiliency visit the town's Climate Change Adaptation Initiative webpage.

An important step to climate change adaptation planning is to gain an understanding of what projected changes and impacts are expected. The expected six climate changes for Oakville were drawn from Environment Canada, Climate Ontario, the International Panel on Climate Change (IPCC) and Canadian Climate Change Scenarios Network (CCCSN). These changes include:

Increase in average annual:

Temperature

Observed change: An increase of 1.3 degrees Celsius between 1976 and 2006.
Projected change: A further increase of 2.6 degrees Celsius by 2050.

Precipitation

Observed change: A 12 per cent increase occurred in the last 50 years.
Projected change: A further increase of 5.1 per cent by 2050.

An increase in the severity and frequency of extreme weather:

High wind

Observed change: An increase of 1.3 degrees Celsius between 1976 and 2006.
Projected change: A further increase of 2.6 degrees Celsius by 2050.

Precipitation, thunder and lightning

Observed change: An increase of 1.3 degrees Celsius between 1976 and 2006.
Projected change: A further increase of 2.6 degrees Celsius by 2050.

Winter precipitation events

Observed change: An increase of 1.3 degrees Celsius between 1976 and 2006.
Projected change: A further increase of 2.6 degrees Celsius by 2050.

Temperature and air quality

Observed change: An increase of 1.3 degrees Celsius between 1976 and 2006.
Projected change: A further increase of 2.6 degrees Celsius by 2050.
