Climate Change: Key Facts

Global warming and Climate Change refer to an increase in average global temperatures. Natural events and human activities are believed to contribute to this increase, as they cause a spike in greenhouse gases such as carbon dioxide (CO2).

  • The Ministry of Environment and Climate Change for Ontario has identified that buildings and the energy they consume account for almost one-quarter of Ontario’s total greenhouse gas emissions (GHGs).
  • EcoSchools states that GHGs typically include carbon dioxide, methane and water vapour, which trap heat in Earth’s atmosphere and warm the planet. A warmer planet results in more erratic weather patterns, rising sea levels and higher CO2 levels in the air and oceans, which in turn affect plant and animal life.
  • Scientist and environmental activist Dr. David Suzuki states that humans are largely responsible for global warming through burning fossil fuels and cutting down forests, which help to mitigate higher CO2 levels. He also says that addressing the problem creates opportunities.
  • Pope Francis’s encyclical on ecology, Laudato Si, says that climate change is real and mainly “a result of human activity.” He states that faith can guide us to a solution.

Did you know?

  • Eating more locally grown foods will help you reduce your carbon footprint, as transporting foods from distant locations increases fossil-fuel use
  • Choosing foods with minimal or recyclable packaging reduces the stress on landfills, as does composting kitchen scraps and garden trimmings, which can produce greenhouse gas emissions in landfills
  • Transportation causes about 25 per cent of Canada’s greenhouse gas emissions! Reduce your carbon footprint by walking, cycling, using public transit, car-sharing or carpooling instead. Whenever possible, use the smallest, most fuel-efficient vehicle possible.
