Climate Change

What causes Climate Change?

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.

What activities produce greenhouse gases?

  • Burning fossil fuels - coal, oil or gas
  • Using electricity generated by burning fossil fuels
  • Land clearing
  • Breakdown of food and plant wastes and sewage.

The main greenhouse gases generated by human activity are carbon dioxide, methane and nitrous oxide.

What are the effects of Climate Change?

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.

Understanding Climate Change

View part of a presentation by Professor Andy Pitman of the UNSW Climate Change Research Centre. The presentation includes the basics about climate change, the causes, effects and impacts of global warming and sea level rise.

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:
