What's climate change?

In recent decades there's been an increase in average and extreme temperatures around the world. This is climate change

Temperatures are rising due to an increase in greenhouse gases in the Earth’s atmosphere. The light (the sun) is getting in, but not as much heat is getting out.

The extra greenhouse gases are caused mainly by human activity since the industrial revolution. The burning of fossil fuels for electricity, industry and transport is a major cause. Another is the large-scale removal of forests. Trees absorb carbon dioxide (a greenhouse gas) from the air and put oxygen back into it. 

By changing how we use energy and resources, we can help reduce the impact of climate change. We can also better respond to the challenges of climate change. For more on what climate change is see AdaptNSW
