Australia is the most fire prone of all of Earth’s continents. But what has made its latest fire season so extreme? Wildfires need four ingredients: available fuel, dryness of that fuel, weather conditions that aid the rapid spread of fire and an ignition. Climate change is making Australian wildfires larger and more frequent because of its effects on dryness and fire weather.
This includes the reduction in rainfall over time, the three winters where the rains have failed to come and the positive trend in the Southern Annular Mode (SAM).
Umair Irfan also unpacks these variables for Vox, touching on both the Southern Annular Mode and the Indian Ocean Dipole.
