Global Warming
- Global warming (Réchauffement planétaire)
- Global warming (as well as global cooling) refers specifically to any change in the global average surface temperature. In other words, global warming or cooling is one type of planetary scale climate change. Global warming is often misunderstood to imply that the world will warm uniformly. In fact, an increase in average global temperature will also cause the circulation of the atmosphere to change, resulting in some areas of the world warming more, while other areas warming less than the average. Some areas can even cool. (Meteorological Service of Canada)
