Australia, scarred by bushfires, on high alert for dangerous summer

Australia is once again on high alert, bracing for what weather experts say will be the hottest, driest period since the so-called Black Summer four years ago

Four years since bushfires destroyed wide swathes of southeastern Australia, killing 33, the country is once again on high alert, bracing for what weather experts say will be the hottest, driest period since the so-called Black Summer.

Just into the Australian spring, which starts in September, heat records are being broken in the densely populated area around Sydney, with some regional schools closed due to bushfire risk a month before the official bushfire season begins.

Adding to the tension, unusually heavy rain since the fires of 2019 and 2020 has spurred vegetation growth, producing more foliage to burn in an El Nino weather system, typified by hot, dry weather, which was declared on Tuesday.

"Once we've actually dried out the landscape from the wet conditions it's starting from, it could be that we end up with a landscape that's very dry but now has a lot of fuel because we've had such good vegetation growth," said Jason Evans, a professor at the Climate Change Research Centre at the University of New South Wales.

"That would be perfect conditions for bushfires," he said.

Australians watched with grim recognition as wildfires ripped through Europe and North America in the 2023 Northern summer. Now there is a sense that it is the Australians' turn again, with global warming speeding up and exaggerating changes in weather patterns, according to climate scientists.

Of Australia's 10 hottest years on record, eight were since 2010, meteorologists say.
