The Department for the Environment and Water has published a comprehensive report card on the status of key climate themes.

The study also includes climate projections to provide insight into new challenges such as drier and warmer conditions.

The publication of the evidence-based assessment coincides with the start of the United Nations COP28 climate change conference in Dubai on 30 November.

This research supports the State Government’s commitment to reduce net greenhouse gas emissions by at least 50% (from 2005 levels) by 2030 and achieve net-zero emissions by 2050.

Key findings from the South Australian Environmental Trends and Status Report Card include:

  • Average temperatures in South Australia are now 1.1 degrees warmer than they were in the 1970s.
  • Average daily maximum temperatures across the state are projected to increase by an additional 1.4°C to 2.2°C by 2050 compared to 1986-2005.
  • The frequency of days reaching 40 degrees Celsius in Adelaide has tripled in the past decade (2013-2022) to 5.1 days per year, compared to an average of 1.7 days per year over the past 40 years.
  • Average annual rainfall across the Southeast is projected to decrease by 4% to 23% by 2050.
  • The Hills and Fleurieu landscape region is projected to experience an 8% to 12% decrease in average annual rainfall by 2050.
  • Sea levels along the state’s coast have risen at an average rate of 2mm per year from 1966 to 2022.
  • SA’s greenhouse gas emissions fell by 42% between 2004-2005 and 2020-21, and renewable energy use increased from 1% to 69% over the past 20 years.

The Department of Environment and Water has also released a new online tool to give businesses, government agencies and communities access to climate projection maps and data.

An interactive map shows projected changes in temperature and precipitation across South Australia for various time periods into the future.

Climate data can be displayed in 10km and 50km grids, or by individual SA landscape regions or local health network areas.

Department of Environment and Water Chief Climate Change Scientific Adviser Graham Greene said a new interactive map showing projected changes in average temperature and precipitation across South Australia would help governments and businesses better understand how to adapt to climate change. He said it would be a valuable tool to help plan.

“Reduced rainfall will lead to less water availability in some regions, while rising temperatures and less rain will mean increased demand for irrigation water to grow crops,” Dr Green said. Ta.

“Small decreases in precipitation can have a big impact on the amount of water flowing into reservoirs and agricultural dams. As landscapes become drier and days with temperatures above 40 degrees increase, the risk of wildfires increases. will increase.

“Analyzing this data can help us understand and manage these climate risks, ensuring water security, protecting agricultural production, and preparing for wildfire threats.”
