VIDEO: Wall of fire tears through Australian outback as scientists say 2023 will almost certainly be Earth's warmest for 125,000 years

A wall of fire has teared through Australian farmland as scientists warn 2023 is likely to be the hottest on Earth for 125,000 years.

Residents in multiple states are being warned of very high to extreme weather conditions as the country braces for a fierce bushfire season due to the El Niño weather system.

Residents in three areas of northern Queensland have been ordered to evacuate their homes as bushfires burned out of control.

Firefighters including those flown in from across Australia and New Zealand have been battling blazes in the state that have already killed and destroyed dozens of homes.

Video from Tennant Creek in the Northern Territory captured a whirling 'firenado' tearing through an outback property as multiple bushfires burned.

New guidelines have been issued for elite sport to minimise the health risk of smoke haze on athletes.

Climate and fire experts have warned Australians face an increased of risk of bushfires this year, with authorities offering a stark outlook for spring across much of eastern Australia.

It comes as scientists claim that 2023 will be Earth's warmest year for 125,000 years.

European Union scientists said October was the warmest on record by a massive margin.

Last month exceeded the previous highest October average temperature, from 2019, by 0.4 degrees Celsius, the EU's Copernicus Climate Change Service (C3S) Deputy Director Samantha Burgess said, describing the temperature anomaly as "very extreme".

That has made 2023 as a whole "virtually certain" to be the warmest year recorded, C3S said in a statement.

The heat is a result of continued greenhouse gas emissions from the burning of fossil fuels, combined with the emergence this year of the naturally occurring El Nino climate pattern, which warms the surface waters in the eastern Pacific Ocean.

The current hottest year on record is 2016 — another El Nino year — although 2023 is on course to overtake that.

Globally, the average surface air temperature in October was 1.7C warmer than the same month between 1850 and 1900, defined as the pre-industrial era, before humans started burning fossil fuels at scale.

It puts further pressure on world leaders to get an ambitious outcome at the United Nations climate change conference in Dubai, COP28, at the end of this month.

There, nearly 200 countries will negotiate stronger action to fight climate change.

A central issue at COP28 will be whether governments agree, for the first time, to phase out the burning of carbon dioxide-emitting fossil fuels.

Under fossil fuel producers' current plans to extract coal, oil and gas, by 2030 global fossil fuel production would be more than double the levels that are deemed consistent with meeting globally agreed goals to limit climate change, the United Nations and researchers said.

Despite countries setting increasingly ambitious targets to gradually cut emissions, so far that has not happened.

Global CO2 emissions hit a record high in 2022.
