Australia’s worrying future under climate change was laid bare last week when the first National Climate Risk Assessment was released. It revealed extreme heat, fires, floods, droughts and coastal inundation already threatens lives and livelihoods – and will wreak further havoc in coming decades.

Much media attention focused on the effects in the continent’s south, where most Australians live. But the assessment found Northern Australia will be hardest hit on many fronts, including extreme heat.

This has major implications. Big plans are afoot to turn Northern Australia into Asia’s “food bowl”, as part of broader development for the region. It would involve building large-scale irrigation, dam and water infrastructure to increase agricultural production, create jobs and boost local economies.

But any discussion about transforming Northern Australia must confront the climate hazards threatening the region’s prosperity.

Northern Australia comprises roughly 53% of Australia’s land mass.

Turning the region into a food bowl would involve irrigating savannas and other ecosystems across northern parts of Western Australia, the Northern Territory and Queensland. The concept dates back decades, but gained momentum in 2015 when the Abbott government released a national white paper on developing Northern Australia.

Tropical cyclones Ragasa and Yasi represent one dangerous threat to a northern Australian food bowl. Ragasa being significantly stronger than Yasi indicates AGW is making tropical cyclones stronger.

It was worse than Yasi, HUGE gusts!

China’s emissions are about 29% of the global total –
more than twice that of the United States, the world’s second-biggest emitter.

The new study found:

Based on those 242 wildfires, the researchers found the number of disastrous wildfires had increased more than fourfold from 1980 to 2023. Nearly half of the fires, 43 percent, were in the last 10 years of the record. Additionally, there were 43 wildfire disasters that cost more than $1 billion in that same period. (The Trump administration said in May it would stop tracking billion-dollar disasters that occur in the United States.)

The findings contrast with those of the 2016 paper, now not even a decade old. But Cristina Santín, a wildfire scientist with the Spanish National Research Council and an author of that earlier paper, was not surprised that the new study had found a different answer from hers. She was glad to see an updated look at trends in damaging wildfires.

“This is proof that things are getting worse,” Dr. Santín said. “We need to adapt to live with fire. This is our reality, and it’s not going anywhere.”

The disastrous fires were largely clustered in the western part of North America, southern Europe and southern Australia, and mostly in affluent areas with high property values — but not exclusively.

Wildfire disasters also struck in the tropics and the far north, mostly driven by unusually strong droughts, and in more rural regions like Nepal that don’t often get Western media coverage. They hit every continent except Antarctica.

They found that the fires were closely associated with “fire weather,” which includes strong, dry winds, high temperatures and drought. Other research has found that fire weather is on the rise as a result of climate change.

“It’s clear that these events are driven by extreme weather,” Dr. Cunningham said. Climate change isn’t solely responsible for all the disastrous wildfires in the study, he stressed, but “it sets the stage” for them.

“Climate change is creating more opportunities for a catastrophic fire,” he said.

Of course, I doubt the bonehead even read the very lengthy Abstract to the paper I cited.

We evaluated the causes and predictability of four extreme wildfire episodes from the 2024–2025 fire season, including in Northeast Amazonia (January–March 2024), the Pantanal–Chiquitano border regions of Brazil and Bolivia (August–September 2024), Southern California (January 2025), and the Congo Basin (July–August 2024).
