What is climate change?

Climate change is a change in the pattern of weather, and related changes in oceans, land surfaces and ice sheets, occurring over decades or longer. According to the Australian Academy of Science, “Earth’s climate has changed over the past century. The atmosphere and oceans have warmed, sea levels have risen, and glaciers and ice sheets have decreased in size. The best available evidence indicates that greenhouse gas emissions from human activities are the main cause. Continuing increases in greenhouse gases will produce further warming and other changes in Earth’s physical environment and ecosystems.”

In its latest findings, the world’s leading body for assessing climate change – the Intergovernmental Panel on Climate Change (IPCC) - reports that human influence on the climate system is clear. Information on the latest climate change science is available on the IPCC website.

Climate change is and will continue to affect our state and our community in a number of different ways. Find out more about how climate change is affecting South Australia and see climate projections for the state.
