Life In Canada
As a cold northern
country, Canada will be
one of the most greatly affected countries in the world. Temperatures are rising, particularly in the Arctic, where permafrost is thawing and the ocean's ice cover is shrinking. Even greater changes are expected in the future.

The Greenhouse Effect

The earth is surrounded by a thin layer of gasses called the atmosphere. Initially, solar energy from the sun passes through our atmosphere. Some of this energy is immediately reflected back out to space and the remaining energy is absorbed by the earth’s surface. The surface of the earth gets heated by the sun’s energy and it then radiates the heat back out towards space. The Greenhouse Effect is a natural process by which the earth is kept at a relatively constant temperature. Without the greenhouse effect, the average temperature of the earth would be –18°C (compared to the current average of +15°C).

Many gases found naturally in the earth’s atmosphere act like a greenhouse (hence the term greenhouse gasses) and help to keep the sun’s heat in, preventing it from dissipating out into space. Some of these gasses include Carbon Dioxide (CO2), Methane (CH4), Water Vapour (H2Ov), and Nitrous Oxide (NOX).

Since the Industrial Revolution, developed countries have produced increasing quantities of greenhouse gases, due to the burning of fossil fuels such as coal, oil, and natural gas to drive our vehicles, power our industries, and heat and cool our homes. More greenhouse gasses in the atmosphere means that more heat is being trapped, causing the earth’s temperature to rise.
