Explainer: the models that help us predict climate change
What will the weather be like next week, next season, or by the end of the century? In the absence of a second Earth to use in an experiment, global weather and climate model simulations are the only tools we have to answer these questions.
Warmer, wetter, hotter, drier? How to choose between climate futures
Some climate models show that, under high greenhouse gas emissions, Sydney could be up to 4.8C hotter and have 20% less rainfall by 2090. Others show the Harbour City could warm only by 2.3C and become 25% wetter. How do we deal with such large uncertainty?

What will Australia look like in 2050? Even if we significantly reduce our greenhouse gas emissions as under an intermediate scenario, Melbourne’s annual average climate could look more like that of Adelaide’s, and Adelaide’s climate could be more like that of Griffith in New South Wales.
