Reason Aussies will no longer be able to visit popular holiday islands: 'Very worrying'
Ice is melting and sea levels are rising faster than previously thought, and scientists are pretty sure low-lying regions of the South Pacific like Vanuatu, Tuvalu, and Micronesia will be lost over the next century, meaning you won't be able to visit them anymore.
Global warming currently sits at 1.2 degrees above temperatures before the world industrialised. The Paris Agreement sets a target of limiting warming to 1.5 degrees, but even if world leaders and industry slash emissions enough to somehow meet that target, new analysis indicates we won't be able to stop accelerated melting of ice sheets in Antarctica and Greenland.
Sea level rises over the next centuries will likely be metres, an international team led by Durham University found, after it reviewed the world's best available data. Lead author and geologist Dr Professor Chris Stokes warned the melting of Greenland and Antarctic ice sheets will see 'rates of one centimetre per year not out of the question within the lifetime of our young people'.
Speaking with Yahoo News from the UK, Stokes explained the problems aren't something to worry about in the distant future, they're already occurring. Asked if he was 'worried', his answer was blunt. 'I'm very worried,' he said.
What he's concerned about is the future of the 230 million people who live in an area vulnerable to one metre of sea level rise.
'If you look at the evidence we've presented in our paper, that means we'll have to move a couple of hundred million people, or spend money on coastal defences. Unfortunately, some of the worst-affected countries are those that can least afford to protect themselves,' he said.
Any country with a coastline is potentially vulnerable to these kinds of issues, but even landlocked countries may be impacted by migration. This is happening now, but the higher the warming and the longer it is sustained, the greater the sea level rise will be, and the more it will cost us in the long run to adapt.'
Globally, there is cause for concern when it comes to slowing global warming. Under the Trump administration, the United States is withdrawing from commitments to tackle the problem, and doubling down on the extraction of fossil fuels — the primary contributor of man-made climate change.
Even countries like Australia, which have net-zero ambitions, are continuing to approve large numbers of new fossil fuel projects. The nation is the third largest exporter of fossil fuels in the world and during the 2023-24 financial year, taxpayers handed over $14.5 billion in subsidies to these projects.

As the scientists released their new report, which was published in the journal Communications, Earth and Environment, they urged leaders to pay attention to the 'emergency' that's unfolding.
'If you look at what a definition of an emergency is, it's an existential threat that requires immediate action,' Stokes said.
'Yes, things are moving in the right direction, but from a sea level rise perspective, they are not moving anywhere near quickly enough. There has to be a change in our ambition around the need for rapid and drastic cuts in emissions.
'The issue quickly becomes politicised — climate action is going to cost a lot of money and jobs if we aim for net zero by 2030, 2050, 2070. But it will cost an awful lot more if we don't take action. Sea level rise is not going to go away, this is not something we can push under the carpet, it's going to get worse and worse.'

Antarctic climate shifts threaten 'catastrophic' impacts globally
Abrupt and potentially irreversible changes in Antarctica driven by climate change could lift global oceans by metres and lead to "catastrophic consequences for generations", scientists warned Wednesday. More broadly, a state-of-knowledge review by a score of top experts revealed accelerating shifts across the region that are often both cause and effect of global warming, according to a study published in Nature. "Antarctica is showing worrying signs of rapid change across its ice, ocean and ecosystems," lead author and Australian National University professor Nerilie Abram told AFP. "Some of these abrupt changes will be difficult to stop." Shifts in different facets of Antarctica's climate system amplify each other and have accelerated the pace of warming globally as well, she said. The study looked at evidence of abrupt change -- or "regime shifts" -- in sea ice, regional ocean currents, the continent's ice sheet and ice shelves, and marine life. It also examined how they interact. Floating sea ice does not add to sea level when it melts. But its retreat does replace white surfaces that reflect almost all of the Sun's energy back into space with deep blue water, which absorbs the same amount instead. Ninety percent of the heat generated by manmade global warming is soaked up by oceans. - Retreating sea ice - After increasing slightly during the first 35 years that satellite data was available, Antarctic sea ice cover plunged dramatically over the last decade. Since 2014, sea ice has retreated on average 120 kilometres (75 miles) from the continent's shoreline. That contraction has happened about three times faster in 10 years than the decline in Arctic sea ice over nearly 50. The "overwhelming evidence of a regime shift in sea ice" means that, on current trends, Antarctica could essentially become ice free in summer sooner than the Arctic, the study found. This will speed up warming in the region and beyond, and could push some marine species toward extinction. Over the last two years, for example, helpless emperor penguin chicks perished at multiple breeding grounds, drowning or freezing to death when sea ice gave way earlier than usual under their tiny feet. Of five sites monitored in the Bellingshausen Sea region in 2023, all but one experienced a 100 percent loss of chicks, earlier research reported. Unlike sea ice, ice sheets and the ice shelves to which they are connected are on -- or supported by -- land. The world would need to heat up by five degrees Celsius compared with pre-industrial levels to melt the entire Antarctic ice sheet, which would lift global oceans an almost unimaginable 58 metres (nearly 200 feet). - Point of no return - But global warming to date -- on average about 1.3C -- is fast approaching a threshold that would cause part of the ice sheet to generate at least three metres of sea level rise, flooding coastal areas inhabited today by hundreds of millions, the study said. "Unstoppable collapse of the West Antarctic Ice Sheet is one of the most concerning global tipping points," said Abram. "The evidence points to this being triggered at global warming well below 2C." Another potential risk is the collapse of the Antarctic Overturning Circulation, a system of ocean currents that distribute heat and nutrients within the the region and globally. A "rapid and substantial slowdown" of the currents has already begun, and evidence from the previous interglacial period -- between two ice ages -- before our own, 125,000 years ago, points to an abrupt stagnation of the system under conditions similar to those seen today. "This would lead to widespread climate and ecosystem impacts," ranging from an intensification of global warming to a decrease in the ocean's capacity to absorb CO2, the study reported. Ultimately, the only way to slow down the interlocking changes is to stop adding more planet-warming gases into the atmosphere. "The greenhouse gas emission decisions that we make over the coming decade or two will lock in how much ice we will lose and how quickly it will be lost," Abram said. mh/jxb Solve the daily Crossword

Major challenge in hunt for 'extremely valuable' 3kg item seen briefly on CCTV
In the days after an 'extremely valuable' meteorite hit the Earth this month, scientists were able to triangulate its collision point to a 1km x 3km area of farmland in central Victoria. It's not the cash value that interests an expert crew from Monash University, but rather its importance to understanding the ancient history of our galaxy. Dr Rachel Kirby, a geochemist at the university, believes the meteorite could be 4.5 billion years old, making it older than the Earth. 'It has the story of our solar system recorded in it,' she told Yahoo News. By studying the meteor and others like it, the team can build a complex understanding of the composition of the solar system without having to dispatch expensive spacecraft. Through the interdisciplinary Desert Fireball Network, a group that specialises in meteorite detection, the Victorian team has been working with an expert on the other side of Australia, based at Curtin University. They have deduced that the rock likely came from the inner asteroid belt, 179.5 to 329 million kilometres away, and then began an orbit into the path of Earth. Similar finds are made from iron, nickel and pieces of rock. Locating this one is particularly challenging because of where it fell. Moment meteorite captured on home security cameras For the last week, the researchers have been scouring paddocks for its landing site. They're not the only space enthusiasts looking for the meteorite, but it's hoped that it will eventually be donated to the Melbourne Museum so its story can be told. Scientists first became aware of the meteorite after seeing video of it hurtling through the sky online on August 10. It was so bright that home CCTV cameras around Bendigo and Ballarat picked up its movement after it entered the atmosphere. 'You can see it stop burning up in the sky, then it falls to the ground like it's been dropped from a tall building. The atmosphere really slows it down, so it might be in a small hole, or sitting closer to the surface,' Kirby said. Major challenge facing meteorite search Because the meteor is thought to weigh just 1 to 3kg and be no bigger than a grapefruit, it's particularly difficult to find. That's because it resembles something else that's very common in paddocks. 'From a distance, animal poo looks a lot like a meteorite, especially when it's fresh. It's dark, and shiny, and round. Cow poos are a little bit easier to tell apart, but when it comes to horses, it's a challenge,' Kirby said. Most locals are excited by the attention it's brought to their area and have welcomed the scientists onto their land, but a handful have refused permission, so it's possible the meteorite will never be found. Incredible feeling of holding a meteorite Since she began searching for meteorites last year, Kirby has found three. Her current search coincides with sunnier daytime weather in central Victoria, so the team is also on the lookout for snakes, and have donned high boots. Because her last major expedition was in Antarctica over the summer, she has first-aid training and experience in surviving in remote places. Her next search will take place on the Nullabor Plain, a vast arid area in southern Australia. 🌏 Extraordinary car park video believed to show new animal species 🧬 Device inside black box holds secret to 'mind-blowing' Tasmanian tiger breakthrough 💰 Mutant snails linked to $170 million damage bill in Australia When Kirby holds a meteorite in her hand, she's reminded of how lucky she is to be holding it. 'We're a very small planet in our solar system. Most of our solar system is a vacuum; there's a lot of space between planets. And then a small rock happened to have its path align with ours, and we met in space, and it landed on the Earth,' she said. 'That's just unlikely and really fortunate.'

Major new assessment recognises four separate giraffe species for the first time
A new assessment has concluded there are four distinct giraffe species, overturning the classification of the world's tallest land mammal as a single species. The review of giraffes was described as 'vital' by scientists at the International Union for Conservation of Nature (IUCN) who conducted the work, to better assess their conservation status and target action to protect them. Historically, giraffes have been classified as a single species with nine subspecies, but there has long been uncertainty over their taxonomy – the way in which plants, animals and microorganisms are named, described and classified. There is also an urgent need for better conservation planning for giraffes, which are assessed as 'vulnerable' to extinction on the IUCN's Red List of Threatened Species amid declining numbers, with several of the existing subspecies classified as endangered or even critically endangered. A taxonomic review by an IUCN task force assessed genetic data, which showed DNA with large differences between several giraffe lineages, supporting the recognition of different species, the experts said. The review also looked at notable differences such as skull structure and bone shape across regions and natural features such as a major rivers, rift valleys and desert areas in Africa that could have cut off giraffe populations from each other so they evolved into different species. As a result of the assessment, four distinct giraffe species have been officially recognised, with several recognised subspecies. Experts said it would lead to a more nuanced understanding of the conservation threats and opportunities they face in the diverse regions of Africa in which they live. The IUCN's Michael Brown, one of the co-authors of the assessment, said: 'This landmark taxonomic revision by the IUCN giraffe and okapi specialist group reflects the best available science and provides a globally standardised framework to inform conservation. 'Recognising these four species is vital not only for accurate IUCN Red List assessments, targeted conservation action and co-ordinated management across national borders. 'The more precisely we understand giraffe taxonomy, the better equipped we are to assess their status and implement effective conservation strategies.' The four species are: Northern giraffe, with the subspecies West African giraffe, Kordofan giraffe and Nubian giraffe; the Reticulated giraffe; the Masai giraffe, with the subspecies Masai giraffe and Luangwa/Thornicroft's giraffe; and the Southern giraffe, with the subspecies South African giraffe and Angolan giraffe.
