Climate change is the greatest threat facing our planet. Humans are causing climate change, and humans can stop it getting worse. We can keep our planet healthy for future generations by acting on climate change now and reducing our greenhouse pollution.
What's causing the problem?
Across the world, human activity is causing climate change by adding huge amounts of carbon dioxide (C02) and other greenhouse polluting gases to our atmosphere. The biggest source of greenhouse pollution is the burning of fossil fuels - such as coal and oil - for energy.
Why is the planet warming?
The Earth is wrapped in a delicately balanced 'blanket' of gases. Like a greenhouse in a garden, this insulating layer traps heat from the sun, and sustains life.
Human activities, particularly the generation of energy from fossil fuels, are adding significant amounts of greenhouse pollution to the atmosphere. This pollution stays in the atmosphere for many decades.
Greenhouse pollution is making the Earth's 'blanket' unnaturally thick, resulting in heating up the planet, otherwise known as global warming. This heat trap is also causing many unusual and dangerous changes to our climate and weather systems, best described as climate change.
An unfair share
In Australia, coal-fired power stations are the biggest single source of greenhouse pollution. Because of our huge reliance on coal to generate electricity, Australians are the highest greenhouse polluters, per capita, of all the developed countries.
How do we solve the 'climate crisis'?
We can stop climate change, but only by making major reductions in the amount of greenhouse pollution we create. To cut pollution, we need to drastically change the way we use and produce energy.
Individuals, businesses and governments need to become much more energy efficient and to stop wasting energy. And we need to invest more in clean, renewable sources of energy such as wind and solar power. Read more about "renewable energy".
Renewable energy is available now, safe for the environment and good for our economy. By dealing with climate change, we have an opportunity to make Australia a world leader in renewable energy and create thousands of jobs and export opportunities.
Climate change - what does it mean for Australians?
Australia is particularly vulnerable to climate change - environmentally and economically.
We already live on the driest inhabited continent on earth. Climate change is making most of Australia drier. We are already experiencing more severe droughts in the bush, and water shortages in our cities.
Climate change is bad for our economy, and bad for our individual hip-pockets. In 2006, Cyclone Larry, severe drought and bushfires wiped billions off the Australian economy. These costs flow through to ordinary Australians in many ways, for example, increased food prices and higher insurance premiums.
If we don't take action, climate change will worsen
If we do nothing about our changing climate, Australian scientists at the CSIRO estimate that temperatures in Australia could be up to 2ºC hotter by 2030 and up to 6ºC hotter by 2070.
As temperatures increase we can expect:
More frequent and severe droughts, bushfires, floods and storms
Increased deaths from heatwaves and flooding and higher incidences of dengue fever, malaria and other mosquito-borne diseases
Damage to our farming and tourism economies as crops fail and attractions like ski fields, the Great Barrier Reef and Kakadu disappear
Wildlife extinctions as habitat changes or disappears
No one on this earth would want any of that to happen. This world is ours and if we don't save power and cut down on energy, the world will also be manys graves.
