What is global warming?
Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature.
The Greenhouse Effect• The greenhouse effect is
when the temperature goes up, on Earth, since the sun’s heat and light energy is trapped in the earth’s atmosphere.
• While the heat from the sun enters our atmosphere, the heat has trouble leaving back out our atmosphere
Other Causes of GW
• Turning on a light.• Watching T.V.• Washing or drying clothes.• Using a hair dryer.• Riding in a car.• Heating a meal in the microwave.• Using an air conditioner.• Playing a video game.
Melting polar icecaps will raise ocean levels; the Arctic Ocean could be ice free in summer by 2050.
Controlling the Problem
Carry out energy saving scheme → reduce the pollution produced by burning fossil fuels
Encourage the factories to replace fossil fuels by renewable fuels, which would not cause environmental pollution
Build more plants → reduce the pollutants e.g. CO2
Controlling the Problem
Reduce the use of plastic bags → as burning plastic emit CH4 (Methane)
Recycle the resources, e.g. plastic
Reduce the use of sprays → as CFCs would be emitted out
Controlling the Problem
Plantation Reduce the use of air-
conditioner, which will emit CFCs
Use public transportation instead of private cars → reduce the pollutants emitted by cars
Individual Actions
• Do not throw garbage on the floor.• Do not use deodorant sprays.• Do not dump waste into rivers.• Do not throw dead animals into rivers.• Do not dump toxic waste in the water.
