Climate Change is caused by an increase in the greenhouse gases in the Earth's atmosphere. These gases absorb heat leaving the earth and return some of it, making the earth warmer overall.
The main greenhouse gases generated by human activity are carbon dioxide, methane and nitrous oxide.
On average, the Earth is warming. Its temperature has already risen by around 0.7ºC over the past hundred years, and may rise by between 1/4 and 5.8ºC this century.
Sea levels are rising as oceans expand and glaciers and ice sheets melt.
Changes in weather patterns, such as more severe droughts, heat waves, floods and storms; changes in rainfall patterns; and higher likelihood of bushfires.
Adverse impacts on plants, animals and human health as climate patterns shift.

According to the Climate of the Nation Report (April 2008) developed by the Climate Institute, nine out of ten Australians (89 per cent) are now concerned about climate change, with half (49 per cent) being either extremely concerned (17 per cent) or very concerned (32 per cent). There are some great resources available to find out more about climate change issues and the resources available to reduce your own carbon footprint:
