What is climate change?

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.
What’s causing the problem?
Humans are 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 burning fossil fuels (like coal and oil) for energy.
Why is the planet warming?
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 (like burning coal and oil) are adding huge amounts of greenhouse pollution to the atmosphere. The pollution stays in the atmosphere for many decades. Greenhouse pollution is making Earth’s ‘blanket’ unnaturally thick, and this is heating up the planet. This is commonly called global warming. The heat trap is also causing many unusual and dangerous changes to our climate and weather systems, best described as climate change.
Climate change and you
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 2009, Victoria faced some of the worst Bushfires on record. Professor David Karoly from the University of Melbourne’s School of Earth Sciences discusses how the record heatwaves and prolonged drought prior to the February 2009 bushfires in Victoria could be linked directly to climate change.
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 stop wasting energy. And we need to move to clean, renewable sources of energy.
Renewable energy is available now, safe for the environment and good for our economy. By dealing with climate change, we can make Australia a world leader in renewable energy and create thousands of jobs and new exports.
