Residents rescued from suspicious apartment block blaze in Melbourne
Residents trapped inside a burning Melbourne care facility have been safely rescued, with the blaze regarded as suspicious, AAP reports.

Matsutake mushrooms and persimmons have appeared on supermarket shelves, along with seasonal beers and sakes. In Tokyo neighbourhoods, residents carry portable shrines through the streets at festivals to mark the end of summer, and children get ready for school sports days.
Autumn, though, has yet to make an appearance in Japan. Instead, experts are warning that the crisp, sunny days that usually offer relief at the end of a sweltering summer are still some way off, with one describing the weather as “abnormal”.

Eastern Australia requires “imminent and urgent investment” in energy to bolster the reliability of the electricity grid, the Australian Energy Market Operator says, as it warns of the risk of outages in Victoria and South Australia this summer.
The challenges are detailed in an Aemo report, released on Thursday, which says the grid may come under strain even with 3.4 gigawatts of new generation and storage capacity added to the national electricity market compared with last summer.

At the start of this week Nasa announced that July 2023 had the highest global temperature recorded for that month since 1880. It was also the warmest month on record.
Readers in the UK may find this hard to believe, given the wet and generally miserable conditions in the country that month. Britain received 19% less sunshine and 170% more rain compared with the 1991-2020 average.
Continue reading...Bureau of Meterology says most of the country is likely to be warmer than average, but El Niño pattern is hard to predict with certainty
Australians should prepare for a summer of heatwaves even if an El Niño does not take hold this year, a senior climate scientist at the Bureau of Meteorology has said.
Dr Karl Braganza, the bureau’s national manager for climate services, said this year “could be significant in terms of heatwaves and fires”, but was unlikely to repeat the horrors of the 2019-20 black summer bushfires.

Sydney is expected to hit 23C on Saturday, with the unseasonably warm weather forecast to continue for the rest of the winter.
Hugh McDowell, a meteorologist at the Bureau of Meteorology, said the bureau’s long-range forecast showed Sydney could expect more unseasonable temperatures.

Ocean temperatures around Australia last month were 0.5C above average, as the UN’s weather agency declared the world was now in an El Niño.
El Niño events influence weather extremes around the globe and for Australia increase the risk of drought, heatwaves, bushfires and coral bleaching.

“Very unusual”, “worrying”, “terrifying”, and “bonkers”; the reactions of veteran scientists to the sharp increase in north Atlantic surface temperatures over the past three months raises the question of whether the world’s climate has entered a more erratic and dangerous phase with the onset of an El Niño event on top of human-made global heating.
Since April, the warming appears to have entered a new trajectory. Meanwhile the area of global sea ice has dropped by more than 1 million sq km below the previous low.

The Bureau of Meteorology has placed Australia on “El Niño alert”, warning there is now a 70% chance of the climate system developing before the end of this year.
El Niño tends to reduce rainfall and push up daytime temperatures in winter and spring, increasing the risk of bushfires, heatwaves and coral bleaching on the Great Barrier Reef.

Eastern Australia looks set for a drier winter and spring as a US federal agency predicts an “extremely high likelihood” of an El Niño developing later in the year.
According to the US Climate Prediction Center, a weak El Niño is likely and there is an 80% chance of a moderate El Niño in the next couple of months, with a greater than 90% chance it will persist into our summer.

Parts of coastal New South Wales could receive up to 120mm of rain over the weekend with heavy falls expected from late Saturday.
The rainfall comes 10 days after Sydney broke a century-old temperature record, with 184 days of temperatures exceeding 20C.

Scientists operating a submersible have discovered deep-sea coral reefs in pristine condition in a previously unexplored part of the Galápagos marine reserve.
Diving to depths of 600 metres (1,970ft), to the summit of a previously unmapped seamount in the central part of the archipelago, the scientists witnessed a breathtaking mix of deep marine life. This has raised hopes that healthy reefs can still thrive at a time when coral is in crisis due to record sea surface temperatures and ocean acidification. It also showed the effectiveness of conservation actions and effective management, they said.
Continue reading...Climate researchers say magnitude of predicted weather event uncertain but if an extreme El Niño occurs ‘we’ll need to buckle up’
Climate models around the globe continue to warn of a potential El Niño developing later this year – a pattern of ocean warming in the Pacific that can increase the risk of catastrophic weather events around the globe.
Some models are raising the possibility later this year of an extreme, or “Super El Niño”, that is marked by very high temperatures in a central region of the Pacific around the equator.
Continue reading...New modelling suggests climate change-driven variability will be detectable decades earlier than previously expected
Stronger La Niña and El Niño events due to global heating will be detectable in the eastern Pacific Ocean by 2030, decades earlier than previously expected, new modelling suggests.
Researchers have analysed 70 years of reliable sea surface temperature records in the Pacific Ocean to model changes in the El Niño-Southern Oscillation (Enso) under current projections of global heating.

Global heating continued unabated despite Covid lockdowns, with record Arctic wildfires and Atlantic tropical storms
The climate crisis continued unabated in 2020, with the the joint highest global temperatures on record, alarming heat and record wildfires in the Arctic, and a record 29 tropical storms in the Atlantic.
Despite a 7% fall in fossil fuel burning due to coronavirus lockdowns, heat-trapping carbon dioxide continued to build up in the atmosphere, also setting a new record. The average surface temperature across the planet in 2020 was 1.25C higher than in the pre-industrial period of 1850-1900, dangerously close to the 1.5C target set by the world’s nations to avoid the worst impacts.

Zimbabwe is on the brink of manmade starvation with close to 60% of the population now food insecure, a UN envoy has said.
Hilal Elver, the UN special rapporteur on the right to food, said the situation was likely to escalate political instability in the southern African nation. After an 11-day visit to parts of the country worst hit by the El Niño-induced drought, Elver said widespread food insecurity was being exacerbated by hyperinflation.

Twenty years ago in 1999 a new weather pattern was described for the first time. Now it has shifted up a gear and is causing devastation across east Africa.
The Indian Ocean dipole, sometimes called the Indian El Niño, is an irregular oscillation in which the surface temperature of the sea is alternatively greater in the ocean’s west and its east. The positive phase, when it is warmer in the west, sees more rain in the west and greater chance of drought in the east. These are reversed in a negative phase.
