Over the last 50 – 100 years, increased industrialization and human activities have begun to affect the earth’s natural climate balance.
The burning of fossil fuels has increased the amount of greenhouse gases in the atmosphere which causes the earth to heat up.
This effect is known as global warming.

Climate Change Projections for Ontario
The Ministry of Natural Resources has developed an educational tool to show how Ontario’s climate might be very different in the future if we do nothing, compared to how it might be if we all do our part.
This tool, the Climate Change Mapping Browser, projects temperature and precipitation patterns based on human activities and greenhouse gas emissions.
To see how your actions can make a difference, try the Climate Change Mapping Browser now.
In Ontario, we can expect average temperatures to rise by as much as three to eight degrees Celsius over the next century. Climate change will affect many of the social and environmental values that Ontarians have come to appreciate.
