Burning fossil fuels - coal, oil and gas - to produce electricity emits carbon dioxide (CO2) into the atmosphere where it builds up, blankets the earth and traps in heat, causing changes to the global climate. 
Coal-fired electricity generation is the single biggest source of CO2 pollution worldwide. CO2 is also produced when natural gas is burned, for example for home heating and in industrial facilities. Other greenhouse gases include methane, CFC's (ozone depleting chemicals) and nitrous oxides. |

 Almost every day the news contains reports about global warming. We hear about the millions of cars on the roads in Canada, spewing carbon dioxide (CO2) and smog causing pollutants. Debates rage about how and when to end our reliance on coal-fired electricity generation, the single largest source of greenhouse gases. Disturbing headlines highlight the incredible rate of deforestation happening here and around the world, depleting the planet's natural ability to regulate the climate. What does it all mean? It means that human activity is having a huge impact on the world's climate. |
