Morning Mail: Australia faces climate change 'disaster' Friday: Scientists are joined by security experts to sound the alarm on the environment. Plus, Trump issues another provocative warning to North Korea Extreme heat in Australia could lead to 'revolving' natural disasters. Photograph: Bureau of Meterology Eleanor Ainge Roy @EleanorAingeRoy Good morning, this is Eleanor Ainge Roy bringing you the main stories and must-reads on Friday 11 August. Top stories Military and climate experts, including a former chief of the defence force, have warned that Australia faces potentially "disastrous consequences" from climate change, including "revolving" natural disasters and the forced migration of tens of millions of people across the region, overwhelming security forces and government. The warning comes in submissions to a Senate inquiry which put Australasia at the centre of some of the worst affects of climate change. And in Queensland, the tourism industry is funding research into the most badly damaged parts of its prize attraction, the Great Barrier Reef. An expedition will undertake the first significant underwater study of remote northern sections of the reef, which were severely damaged by coral bleaching, the Guardian can exclusively reveal. Bob Brown says plans to boycott the postal vote on marriage equality if the high court rules in its favour would be a mistake and play into the hands of rightwing MPs. Writing in the Guardian, the former Greens leader argues: "The best way to sideline them is for the postal vote to return a triumphant yes," he writes. "If this vote proceeds, there may be a lot of nastiness, bigotry, hate and destructive accusation. This is nothing new for the LGBTI community. Ladies and gentlemen of Australia, let's gird our loins. I, for one, am ready to take the bullies on." Donald Trump has issued another provocative warning to North Korea, telling the country to "get their act together" or be in trouble "like few nations have ever been". Trump told reporters on Thursday that his previous warning that North Korea would face "fire and fury" if it threatened the US was in fact not tough enough, the Associated Press said. "It's about time someone stood up for the people of our country." The latest remarks came after Trump began the day deploying a highly unorthodox combination of the conservative Fox News channel and Twitter to amplify the words of his defence secretary. North Korea has derided Trump's threats as a "load of nonsense" and announced a detailed plan to launch missiles aimed at the waters off the coast of the US Pacific territory of Guam. A statement attributed to General Kim Rak-gyom, the head of the country's strategic forces, declared: "Sound dialogue is not possible with such a guy bereft of reason and only absolute force can work on him." Graham Lloyd, the environment editor of the Australian, and his partner, Vanessa Hunter, are being sued by a former joint-venture partner in an eco-retreat and Amazonian conservation project in Peru. Cheryl Conway, who provided Lloyd and Hunter with more than $600,000 between 2013 and 2015 to establish the Lupunaluz Foundation and build the Lupunaluz Retreat, has filed an application in the federal court seeking damages for misleading or deceptive conduct and breach of contract. Lloyd says he is not aware of any federal court proceedings and has not been served with any process but will vigorously defend it. A flat in Amsterdam being advertised for rent allows no cooking in the kitchen and only two people in the flat at any one time. The outrageous demands have highlighted the city's crippling housing shortage. Amsterdam has been undergoing a property boom, bringing costs back almost to the levels before the 2008 financial crisis, with prices rising nearly 22%. The Dutch broadcaster RTL, which discovered the ad, also reports that while it has been advertised as a two-room flat, one of those is the bathroom and the other is a joint bedroom/kitchen. A person responding to the add online wrote: "The lack of space and the huge increase in demand due to Airbnb has given landlords an irrational amount of power … now they can start asking for ridiculous conditions and still the apartment will be rented/sold." Sport As of Friday night (London time) the Premier League is back: and even in a league where every season is more pantingly hyperbolic than the last, this feels like a significant one as it marks a quarter of a century since the first Premier League season in 1992. Barney Ronay delves into the coming season of a league that has become defined not by teams built and talent nurtured, but pounds spent, billions dispersed, sacks of cash hurled to the winds. In the World Athletics Championship in London, the men's 200m final is coming up. Follow the action in our live blog. Thinking time Jen Cloher: brave, ambitious and moving. Photograph: Tajette O'Halloran The Melbourne singer–songwriter Jen Cloher has spent a lot of time in the shadow of her partner Courtney Barnett's worldwide success. But her fourth album, self-titled, is a work of real brilliance: brave, ambitious and moving. Cloher has said the lyrics are crucial to understanding this record, and the melodies and song structures are secondary. On one hand, this is true – Cloher has a poet's eye for telling, tiny details – but it also sells the music, and her incredible band, somewhat short. What sort of country does Australia want to be? How do we know what's in the national interest when our great southern land has no clear economic, population, employment or immigration policy? Anne Summers examines this question here. "If we were a person, we might well be considered legally blind. We have no idea what sort of country we want to be," she writes. Aliens, comic-book characters and cartoons have dominated the big screen for too long – Hollywood is in dire need of a Bonnie and Clyde moment, writes Danny Leigh. Fifty years ago the film shook up the studios and ushered in a new wave of auteurs, including Coppola and Scorsese. Released in August 1967, Bonnie and Clyde missed out on the best picture Oscar, but no matter – the influence of the true-ish story has never stopped rippling. Like a flicked switch, it changed the movies forever – leading an onrush of glorious films that caught the mood of the times; youth, sex, violence and adventure. What's he done now? For a president who is taking a very unusual and not-quite-understood "working holiday" at his golf club in New Jersey, it seems a bit rich for Donald Trump to be telling the Senate majority leader, Mitch McConnell, to "get back to work", as he did on Twitter a few hours ago. "Mitch, get back to work and put Repeal & Replace, Tax Reform & Cuts and a great Infrastructure Bill on my desk for signing. You can do it!" Media roundup The Sydney Morning Herald splashes with a half-page picture of Penny Wong, passionately arguing for same-sex couples to be given the right to marry. The SMH also reveals that Tony Abbott has called for Australia to urgently consider a missile defence shield to protect against attack by nuclear-armed North Korea – the second former leader to demand further protection in a month. The Daily Telegraph splashes with a scoop revealing that the Australian army has put a ban on recruiting men in a quest to increase the number of female soldiers. And the ABC says four Queensland coalmines risk closure after allegedly failing to meet their dust-monitoring obligations. The mines are Glencore's Oaky North and Oaky No 1 at Tieri, and Anglo's Moranbah North and Grosvenor, north-west of Rockhampton in central Queensland. Coming up The government will announce this morning that Armidale in NSW has been chosen to house 200 Iraqi and Syrian refugees. Barnaby Joyce will be fronting the media. Federal court proceedings for the ailing Channel Ten, which went into voluntary administration in June, are expected to continue.
