Why is our climate changing? What are the impacts? Here we address some of the common questions raised about the changing climate and the science involved in studying it.
What is climate change?
Climate change refers to any long-term trends or shifts in climate over many decades.
How has climate changed in the past?
There is a great deal of evidence that the Earth's climate has warmed over the past century.
Why do sea levels change?
Sea levels can change for a variety of reasons over a range of different time scales.
How is climate likely to change in the future?
The Earth's future climate will depend on whether the world manages to slow or even reduce greenhouse gas emissions, but warming is likely to continue.
How does CSIRO study climate change?
Our climate researchers use climate simulations to project future climate decades in advance.
What are the impacts of climate change?
Increases in extreme climate events will pose challenges for Australia in the future.
Is the science settled?
A distinction needs to be made between science that is robust and science that is relatively uncertain. All conclusions should be based on peer-reviewed literature.
