Understanding Climate Change

Our climate is changing

In the past century, the global average surface temperature has risen by 0.74 ºC. The observed increase in average temperatures is widespread around the globe, with rising trends recorded on all continents and in the oceans.

Australia’s climate future – Climate change in Australia

Changes to our climate have the potential to create major impacts on human and natural systems. Further changes to our climate are likely as concentrations of greenhouse gases continue to increase.

Human activities are changing the climate

Greenhouse gas emissions from human activities are more than 90 per cent likely to have caused most of the global warming since the mid-20th century. Find out more.

Climate change will continue worldwide

Greenhouse gas emissions at or above present rates will cause further warming and induce many changes in the global climate system during the 21st century. It is very likely that these changes will be larger than those already seen in the past century.

Climate variability, climate change and drought in eastern Australia

Australia has a highly variable climate with a naturally occurring cycle of wet and dry periods. Droughts are an expected product of this variability.

Our Research

The dynamic ocean
The dynamic ocean

- The Wealth from Oceans Flagship is creating and exploiting knowledge of ocean variability and change to deliver social, environmental and economic wealth to Australia. The Wealth from Oceans Flagship is determining howchanges in ocean temperatures, wind patterns and salinity, impact on regional climate conditions.

Researching our climate and weather
Researching our climate and weather

- Our work on climate, weather, oceans, drought and atmospheric pollution is helping Australia lead Southern Hemisphere efforts to understand climate change.

Understanding the connections between land and atmosphere
Understanding the connections between land and atmosphere

- CSIRO research is improving our understanding of how the interactions between land and atmosphere can impact on climate, water resources, environmental health and productivity.

Understanding our living atmosphere
Understanding our living atmosphere

- CSIRO's Living Atmosphere research is seeking ways to ensure a healthy atmosphere, a better understanding of our changing atmosphere, and the interactions between land and atmosphere.

Research to assist climate decision-making
Research to assist climate decision-making

- To help our climate sensitive society make better decisions, CSIRO scientists aim to shape Australia’s adaptation to global climate change, limit the risk associated with climate variations and weather extremes, and generate valuable services to Government, industry, researchers and the community.
