Massive bushfires in southeastern Australia still have a "long way to go", authorities have warned, even as colder conditions brought some relief to exhausted firefighters and communities.
After a blustery night that saw a series of massive infernos in New South Wales and Victoria states merge into a mega-blaze four times the size of Greater London, temperatures dropped and rain fell on fire-scarred regions.
"Whilst it was a very long and - in parts of New South Wales - difficult night, we're relieved this morning that no lives have been lost and no substantial property damage," New South Wales Premier Gladys Berejiklian told reporters today.
The milder conditions are expected to last around a week, giving firefighters time to try to get the fires under control.
New South Wales Rural Fire Service commissioner Shane Fitzsimmons described the conditions as the "best seven days we have had without a rise of very dangerous fire ratings".
In a matter of months, the catastrophic bushfires have killed at least 26 people, destroyed more than 2,000 homes and scorched some 10 million hectares - an area larger than South Korea or Portugal.
University researchers estimate that more than one billion mammals, birds and reptiles have been killed in the blazes.
Despite the cool change, authorities warned that the bushfire season is not yet over, with hundreds of fires across several states still raging.
The head of a firefighting "strike team" in the village of Towamba, Nathan Barnden, told AFP the rainfall was "fantastic" but "not enough at this stage to put these fires out".
"We're going to need hundreds of millimetres over a period of time to... make firefighting easier for us," he said.
In Victoria state, Premier Daniel Andrews called on communities to remain vigilant and warned that the months-long crisis was "a long way from over".
Yesterday, tens of thousands of protesters took to the streets across the nation's cities, calling on Australia's conservative government to take stronger action on climate change.
Scientists say climate change has contributed to the lengthening of the fire seasons and fuelled more frequent and intense blazes.
The Australian Academy of Science, an independent organisation representing the country's leading scientists, said Canberra "must take stronger action" as part of its global commitments to limit global warming.
"The scientific evidence base shows that as the world warms due to human-induced climate change, we experience an increase in the frequency and severity of extreme weather events," the academy's president John Shine said in a statement.
"As a nation, we must deal with extreme weather events more effectively than we currently do."
Australia experienced its driest and hottest year on record in 2019, with its highest average maximum temperature of 41.9 C recorded in mid-December.
Despite growing domestic and international criticism, Prime Minister Scott Morrison - who has long touted the importance of commodity exports such as coal for Australia's economy - has repeatedly defended his government's climate policies.
The unprecedented crisis has also sparked an outpouring of fundraising from celebrities, sportspeople and locals in support of volunteer firefighters at the frontlines and devastated communities.
The Sydney Opera House projected images shot during the fires onto the building's sails today, ahead of a comedy gala fundraiser.
Greta Thunberg calls on Siemens to review Australia coal project
Meanwhile climate activist Greta Thunberg hascalled on German engineering group Siemens AG toreview its role in helping to develop a coal mine project in Australia.
"On Monday they (Siemens) will announce their decision.Please help pushing them to make the only right decision.#StopAdani," Thunberg tweeted today.
Environmental activists are concerned that the continued use of coal as will lead to higher emissions of carbon dioxide, agas which is linked to global warming.
Engineering giant Siemens has said it will decide by Monday on its involvement in the development of the mine which is being built by India's Adani Power, its CEO Joe Kaeser said yesterday.
The Australian government last year approved the construction of a new coal mine in Queensland by Adani that is expected to produce 8-10 million tonnes of thermal coal a year.
Australia is one of the world's largest carbon emitters per capita because of its reliance on coal-fired power plants. The coal from the Adani project is destined for export and would be burned in India.
