Journalist and professional sailor in New South Wales writes about the devastating bushfires in Australia.
2019 was the hottest and driest year on record in Australia. The Indian Ocean Dipole and the Southern Annular Mode weather systems, plus existing drought conditions, all primed the continent for the horrific fire season currently raging in the east and south east of the country. Climate scientist at the University of New South Wales Sarah Perkins-Kirkpatrick is in no doubt global warming played a role in making these the worst fires in recent history. Making matters even worse is that the ferocity of the bush-fires is creating its own weather. Nicholas McCarthy at the University of Queensland studies fire-induced weather and he explains how this can help spread the fires further.
