According to the Australian Academy of Science, soon every year will be a fire season like 2020. My question:- if the forests all burn down, surely we would run out of flammable woodlands?

‘Delay is as dangerous as denial’: scientists urge Australia to reach net zero emissions faster

Heatwaves to double and many properties will be uninsurable if global heating reaches 3C, Australian Academy of Science says

Global heating of 3C would more than double the number of annual heatwaves in some parts of Australia, leave properties uninsurable due to flood and fire risk, and make many of the country’s ecosystems “unrecognisable”, according to Australia’s leading scientists.

The Australian Academy of Science is calling on the Morrison government to accelerate the country’s transition to net zero greenhouse gas emissions in a report that examines what Australia could look like in a 3C world.

The analysis paints a grim picture in which heatwaves in states such as Queensland would occur seven times a year and last for 16 days at a time, and unprecedented fire seasons such as the 2019-20 fire disaster become a regular occurrence.

Prof Lesley Hughes, an ecologist and pro vice-chancellor at Macquarie University, said there were steps the Morrison government could take immediately to encourage the uptake of electric vehicles, rather than inhibit it.

“Delay is as dangerous as denial,” she said.

“The main message we would have for the federal government is that what we do, as well as the rest of the world, in the next decade … that’s the critical thing.”

The Australian People’s Republic of Victoria has developed a solution.

A week ago Victoria celebrated the construction of a green hydrogen plan, which uses brown coal and steam reforming to produce green hydrogen.

Of course, the “green” part is a little theoretical, for now. All the CO2 produced by burning the coal is released into the air, which has led to criticism that the green hydrogen plant is actually very carbon intensive. But supporters claim the plant will be retrofitted with carbon capture as soon as the time is right.

If Australia increases coal exports, so everyone can copy the Victoria’s green hydrogen success, coal burning green hydrogen plants all over the world will be ready to be retrofitted with carbon capture systems, when the time is right.
