The greenhouse effect happens when certain gases—known as greenhouse gases —collect in an atmosphere.

These gases, which occur naturally in the atmosphere, include carbon dioxide, methane, nitrogen oxide, and fluorinated gases sometimes known as chlorofluorocarbons (CFCs)

Greenhouse gases let the sun’s light shine onto the Earth’s surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse

The greenhouse effect keeps Earth’s climate comfortable. Without it, surface temperatures would be cooler by about 33 degrees Celsius (60 degrees Fahrenheit), and many life forms would freeze

Energy production is the largest contributor to Australia’s carbon emissions. This is followed by transport, agriculture, and industrial processes.

Greenhouse gas emissions are also influenced by changes in land use. Total (or net) greenhouse gas emissions factor in the influence of how land is used.

Australia’s greenhouse gas emissions total was reduced as a result of land use, land use change and forestry removing 4.9 per cent of our emissions in 2020.

The Green House effect is when the sun's light shines down onto earth and the heat that gets reflected, becomes trapped. This effect is like a greenhouse's insulating glass walls, therefore its name. Without the greenhouse effect, the temperature would drop by 35 degrees Celsius. We need the Green House Effect, but since the industrial revolution, carbon dioxide (the most contributing greenhouse gas) has increased by 80%. These large amounts of carbon dioxide mainly come from burning fossil fuels. Due to the growing Green House gases, more heat is continually being trapped in our atmosphere, causing climate change.

The impact of the greenhouse effect on Australia is climate change. The consequences of climate change in Australia include increasing land and water temperature, depleting kelp forests and sea grasses, changing rainfall patterns, growing fire danger, rising sea levels, mass coral bleaching and widespread damage to coral reefs around Australia, including the Great Barrier.
