Global Warming

What is Global Warming?

Global warming is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants. You can see what can become of this in image 1. Video 1 is also a great way to further understand global warming and climate change.

What is Australia doing about it?

What is the Greenhouse effect?

The introduction of Carbon Tax was introduced in Australia on the 1st of July 2012. This is meant to discourage people from using excessive amounts of things that produce carbon dioxide as it will now cost them more money.

1) Use Less Heat and Air ConditioningAdding insulation to your walls and installing weather stripping or caulking around doors and windows can lower your heating costs more than 25 percent, by reducing the amount of energy you need to heat and cool your home. Turn down the heat while you’re sleeping at night or away during the day, and keep temperatures moderate at all times. Install a programmable thermostat because setting it just 2 degrees lower in winter and higher in summer could save about 907 kilograms of carbon dioxide each year.2) Plant a Tree          If you have the means to plant a tree, start digging. Trees absorb carbon dioxide and give off oxygen. A single tree will absorb approximately one ton of carbon dioxide during its lifetime.

Two ways you can help to reduce the Greenhouse effect.

What are some ways we can reduce greenhouse gasses?

Greenhouse effect- The trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface. You can see this in image 2.

How does deforestation and the excess burning of fossil fuels both contribute to the greenhouse effect?


Deforestation – Loss of forests contributes as much as 30% of global greenhouse gas emissions. Forests contain carbon-dioxide. The method of deforestation releases carbon-dioxide into the atmosphere. The less trees there are, the more carbon-dioxide can be absorbed into the atmosphere making ‘the blanket’ of gasses thicker and thicker.Excess burning of fossil fuels-   Burning any carbon based fuel converts carbon to carbon dioxide. Unless it is captured and stored, this carbon dioxide is usually released to the atmosphere. Burning fossil fuels releases carbon that was removed from the atmosphere millions of years ago by animal and plant life. This leads to increased concentrations of carbon dioxide in the atmosphere which contributes greatly to the greenhouse effect.

What is the Kyoto Protocol?

The Kyoto Protocol was an agreement between many countries in December 1997 and came into force with Russia's ratification on February 16th 2005. The reason for the lengthy timespan between the terms of agreement being settled upon and the protocol being engaged was because of the terms of Kyoto requiring at least 55 parties to ratify the agreement and for the total of those parties’ emissions to be at least 55% of global production of greenhouse gases. This is a very hard thing to do. Under Kyoto, industrialised nations pledged to cut their yearly emissions of carbon, as measured in six greenhouse gases, by different amounts, averaging approx. 5.2% by 2012 as compared to 1990. That equates to a whole 29% cut in the values of fossil fuels that would have otherwise occurred.
