Climate change




Nature of
What is climate change ?

Changes in the climate of different areas of the planet. These changes can be seen in precipitations, winds, storms… All elements of weather can be affected.

Why is the planet heating up ?

The planet is heating up because of the increased effects of greenhouse gases.

What is the greenhouse effect ?

Around our planet, there is a layer of gases that act like the windows of a greenhouse or a car. This layer is composed of greenhouse gases - carbon dioxide, methane, nitrous oxide. Like the windows of a greenhouse, many solar rays are able to get through the layer of gases. The solar rays then hit the planet and bounce back towards the atmosphere. Some of the rays get through the layer and return into space. However, some rays are trapped inside the layer because it is getting thicker with human production of greenhouse gases. A greenhouse heats up in the same way, which explains the reason why scientists call this the greenhouse effect.

The greenhouse effect is a natural phenomenon and without it, the temperature on Earth would be -18 degrees Celsius. However, this phenomenon has been increased in the last few years and it helps to explain the warming of the Earth.






up Causes

What are the causes of climate change ?

Changes in the climate can occur naturally on the planet over a long period of time, for example the ice ages. They can also be caused by human activity. These modify the atmosphere's composition of greenhouse gases. The concentration of carbon dioxide, nitrous oxide and methane is rising rapidly because of :

  • Burning of fossil fuels (oil, coal, natural gas…)
  • Deforestation
  • Old landfills
  • Population growth





    up Signs
    What evidence exists to prove the occurrence of climate change ?

    Scientists have observed different signs :

  • Rise of the global sea level
  • Increase in global temperature
  • Melting of the glaciers
  • Increase in extreme weather events

Concrete Actions

Here is a list of actions we can do to reduce our production of greenhouse gases and to help the environment

Turn off lights and computers
Recycle
Avoid wasting paper towels
Recycle phonebooks
Limit the use of paper by writing on both sides

Write to government officials to work on reducing gas emissions
Organize a nature walk
Make sure the dishwasher is full before running it
Reduce consumption
Limit the number of times you open the refrigerator door
Turn down the thermostat when no one is home
Re-use
Compost organic material
Plant trees in the schoolyard
Distribute trees to plant at home
Plant your own garden
Create a butterfly garden
Take a "no garbage" lunch to school and encourage the students to do the same

Travel by bicycle when possible
Travel with others or by bus
Calculate your CO2 emissions and encourage others to do the same. Then try to limit them. Buy products with the least amount of packaging.
Limit water use
Adopt a forest
Buy a smaller car
Work at home instead of going elsewhere to work
Install solar panels
Hook up to wind energy
