As Sydneysiders would know after receiving another thorough drenching on Tuesday, La Niña is going out with more of a bang than a whimper. The latest from the Bureau of Meteorology is that the wet weather system could finish up by the end of the month, and international modelling shows there’s a good chance Oz will head into an El Niño event next summer, so get ready to welcome La Niña’s hotter/drier brother… That advice comes as a new Climate Council report warns 3 years of rain have primed Oz for an unprecedented grassfire season. Significant blazes have been recorded in nearly every state/territory in recent months, but they warn it could get worse, with satellite images showing huge fuel loads across the country are starting to dry out, creating a potential “powder keg”. And thanks to expected dry/hot weather, the report says there’s a higher risk of bushfires next summer too. Wouldn’t an uneventful summer be nice…
