7 December 2016, Climate Home, UN to extend freeze on climate change geoengineering. Draft documents suggest countries will agree to further ban on large-scale climate techno-fixes, warning risks of damage to biodiversity outweigh potential benefits. Countries should resist the urge to experiment with large scale planetary geoengineering until it’s clear what the consequences of meddling with the oceans or atmosphere may be. That’s the nub of a decision expected to be taken at the UN’s biannual biodiversity summit taking place in Cancun, Mexico this week, emphasising a “precautionary approach” to such projects. With greenhouse gas emissions closing in on levels that could guarantee warming of 1.5C above pre industrial levels and an El Nino-boosted 2016 likely to be the hottest year on record, some scientists are looking to emergency measures. But the UN is sticking to a familiar line: pumping the atmosphere with tiny mirrors to deflect sunlight, boosting the uptake of CO2 in oceans by stimulating plankton growth, or burning wood and pumping the emissions underground could be a bad idea. “We’re concerned that with any initiative regarding the use of geoengineering there needs to be an assessment,” UN biodiversity chief Braulio Ferreira de Souza Dias told Climate Home. “These can have unforeseen results and spin-offs. If you capture carbon in the oceans, this is effective through all the food chains.” Even national risk assessments on individual geoengineering projects would still form an “incomplete basis for global regulation” says the latest iteration of the UN draft decision, echoing previous Convention on Biological Diversity (CBD) decisions in 2010, 2012 and 2014. “More trans-disciplinary research and sharing of knowledge among appropriate institutions is needed,” it says, citing potential impacts on ecosystems and potential ethical issues.

7 December 2016, Climate Home, There’s a secret UN climate summit taking place in Mexico. UN biodiversity chief tells Climate Home protecting and restoring ecosystems is the best way to protect the world from dangerous levels of global warming. There’s a UN climate change meeting involving nearly 200 governments taking place right now in the Mexican holiday resort of Cancun. It’s not making many headlines, but then the biannual UN Convention on Biological Diversity (CBD) conference rarely does. Especially not in a year like 2016. And that’s a pity, because at stake is the air you breathe, the trees that surround you and the fate of the earth’s 8.7 million species of flora and fauna. Also at stake is the ability of communities across the world to cope with erratic weather patterns linked to climate change like flash flooding, acidifying oceans, drought and storms. “Everything is inter-linked,” says Braulio Ferreira de Souza Dias, a former Brazilian government official who has been executive secretary of the CBD since 2012. “If countries want to meet the Paris climate agreement and the sustainable development goals in 2030 they also need to make progress in biodiversity.” That means slowing and then reversing deforestation so there are more trees to suck up carbon emissions from fossil fuels, and managing wetlands that can act as a buffer against storm surges. It means working out how countries can better manage livestock and look after fish stocks so species can be supported if their habitats are damaged or waters become too acidic. “Unless we can do a better job we won’t make it,” says Dias, who argues that countries and businesses are – eventually – starting to understand why biodiversity matters. The Brazilian leaves his role after this meeting, but he wants governments to understand that building walls as protection – no Trump pun intended – is not going to crack it. Read More here
16 November 2016, The Conversation, As the world pushes for a ban on nuclear weapons, Australia votes to stay on the wrong side of history. In early December, the nations of the world are poised to take an historic step forward on nuclear weapons. Yet most Australians still haven’t heard about what’s happening, even though Australia is an important part of this story – which is set to get even bigger in the months ahead. On October 27 2016, I watched as countries from around the world met in New York and resolved through the United Nations’ General Assembly First Committee to negotiate a new legally binding treaty to “prohibit nuclear weapons, leading towards their total elimination”. It was carried by a majority of 123 to 38, with 16 abstentions. Australia was among the minority to vote “no”. Given that overwhelming majority, it is almost certain that resolution will be formally ratified in early December at a full UN general assembly meeting. After it’s ratified, international negotiating meetings will take place in March and June-July 2017. Those meetings will be open to all states, and will reflect a majority view: crucially, no government or group of governments (including UN Security Council members) will have a veto. International and civil society organisations will also have a seat at the table. This is the best opportunity to kickstart nuclear disarmament since the end of the Cold War a quarter of a century ago. And it’s crucial that we act now, amid a growing threat of nuclear war (as we discuss in the latest edition of the World Medical Association’s journal). But the resolution was bitterly opposed by most nuclear-armed states, including the United States and Russia. Those claiming “protection” from US nuclear weapons – members of the North Atlantic Treaty Organization (NATO), and Japan, South Korea and Australia – also opposed the ban. This is because the treaty to be negotiated will fill the legal gap that has left nuclear weapons as the only weapon of mass destruction not yet explicitly banned by international treaty.

3 November 2016, Climate Home, UNEP: global climate action “still not good enough” – Greenhouse gas emissions need to fall a further 25% from projected levels in 2030 to meet 2C global warming limit, says report. A day before the Paris climate agreement is fêted into international law, the UN has issued a stark warning that political compromises have kept the world on track for disastrous global warming. In a major annual stocktake of global action to reduce carbon – the Emissions Gap Report released on Thursday – the UN Environment Programme (UNEP) called on the leaders of the world to bring their emissions targets into line with the advice of scientists. Under the Paris climate agreement, which comes into effect on Friday, nations agreed to limit warming “well below 2C” and strive for less than 1.5C. But the collective pledges of nations under the Paris agreement fall far shy of either goal – sending the temperature shooting up to 3.2C above pre-industrial levels by the end of the century. The warmer the world becomes, the more destructive and painful climate change will be. The report was released a week before climate talks resume in Morocco and it is hoped the process of increasing ambition will begin. In order to get on track, nations must cut a further 25% off their projected emissions by 2030, said UNEP head Erik Solheim: “It’s still not good enough if we are to stand a chance of avoiding serious climate change.” Read More here
