This document discusses a community science forum on farming sustainability and technologies in relation to climate change and Australian farming systems. It outlines the causes of climate change, including greenhouse gases, and how changes to the atmosphere can impact regional and local climates. Researchers explore using climate change projections, temporal and spatial analogues, and sensitivity analysis to understand how future climates may impact farming systems and what farmers can learn to increase resilience.
