During the late 1970s it became increasingly clear that the planet was warming, this 1984 documentary outlines our understanding of global climate change at the time.

There’s weather, and then there’s climate. Weather patterns come and go, but forecasting has become much more accurate through improved meteorological techniques. Climate change is harder to predict. But, as the CBC’s Peter Kent shows in this 1984 documentary, it’s happening.

Carbon dioxide levels in the Earth’s atmosphere have been steadily rising, and by the year 2100 the average global temperature may rise by five degrees Celsius due to the greenhouse effect.
