Climate change is affecting extreme weather across the planet. But with a single event, like the Feb/March 2022 event that caused flooding in Australia, can we always say climate change is to blame? For this extreme rainfall event, Australian researchers say there is insufficient evidence at present to say that human-caused climate change played a major role. They say, this does not mean that climate change did not play a role — just that with our existing observational record, and with the current ability of climate models, we are limited in the strength of the conclusions we can draw. The researchers say scientists should carefully consider how they word statements making links to climate change in the aftermath of extreme events.
