Global carbon dioxide levels hit record highs in 2020. But through incredible luck, or perhaps a Pacific La Niña event, Australia is now less likely to get massive bushfires this summer.
Looks like carbon dioxide will now cause more floods and cyclones, not fires and droughts.
It’s just physics, you know.
La Niña set to bring cooler weather, more rain and cyclones to Australia
Lisa Cox, The Guardian
The last La Niña occurred from 2010-2012 and brought widespread flooding and record rainfall. The Bom said its modelling currently suggested the latest event would be strong but would not reach the same intensity.
[Andrew] Watkins said La Niña would likely bring increased rainfall in both northern and eastern Australia and increased risk of flooding. It also raises the chance of increased cyclone activity during the tropical cyclone season, with a typical season being nine to 11 cyclones.
He said an active La Niña would also reduce the bushfire risk this season slightly, but would not eliminate it.
Dr Joelle Griggs, a climate scientist at Australian National University, reminds us that even in La Niña years sometimes early rain produces bulk grass which, if […]
