14 December 2015, Energy Post, Paris emission cuts aren’t enough – we’ll have to put carbon back in the ground. With the Paris climate deal, the world has created the mother of all take-back schemes, writes Myles Allen, Professor of Geosystem Science at the University of Oxford. According to Allen, fossil fuel companies don’t necessarily have to stop producing CO2 – they just need to be required to ensure it doesn’t end up in the atmosphere. #takebackCO2 – start tweeting it now! Courtesy of The Conversation. I wonder how many of the delegates in Paris realise that they have just created the mother of all “take-back schemes”. As a consumer, you may have already come across this sort of deal: if you don’t want to dispose of the packaging of your new sofa, you can take it back to IKEA and it’s their problem. In many places, you can even take back the sofa itself when your kids have wrecked it. For the Paris climate deal to succeed something similar will have to happen, where companies that rely on fossil fuels will be obliged to “take back” their emissions. The agreement reaffirms a commitment to stabilising temperature rises well below 2℃, and even retains the option of limiting warming to 1.5℃ if possible. But it also confirms national targets that do little more than stabilise global emissions between now and 2030. Given those emissions, sticking to within 2℃ will require us to take lots of carbon out of the atmosphere and store it in the ground. The parties to the agreement are, in effect, saying “we’re going to sell this stuff, and we’re going to dispose of it later”. How do I know? Well, peak warming is overwhelmingly determined bycumulative carbon dioxide emissions. To stabilise temperatures at any level, be it 1.5℃, 2℃ or even 3℃, net carbon dioxide emissions must be reduced to zero. Most governments, environmental groups and business leaders now understand this. And it is acknowledged, albeit implicitly, in Article 4 of the Paris agreement, which calls for greenhouse emissions to be “balanced” by carbon sinks some time after mid-century. But we’re unlikely to hit “net zero” emissions before temperatures reach 2℃, and even less likely before they reach 1.5℃. Warming is currently at about 1℃ and rising by 0.1℃ every five to ten years. We could slow the warming by reducing emissions, of course. But if we fail to reduce at the required rate – and the inadequate emissions targets indicate this is the intention – then we will be left with no option but to scrub the excess CO2 back out of the atmosphere in future.

13 December 2015, Renew Economy, Lomborg legacy: Why Turnbull Coalition still doesn’t get it. In the final, frantic, virtually sleepless hours in Paris before the global climate deal was finalised on Saturday, Australia found itself on the outer of a powerful international movement. Canada, once joined at the hip with Australia as one of the developed world’s two “climate dunces”,signed up to the Coalition for High Ambition – a 100-strong grouping of countries pushing for an ambitious climate treaty that sought to limit global warming to 1.5°C. Then came Brazil, breaking away from its traditional allies India and China to declare that “if you want to tackle climate change, you need ambition and political will.” It was not a formal voting block, but its influence in the final days of the talks was critical. This was acknowledged by the cheers in the plenary session on the final day of the Paris talks when Marshall Islands foreign minister Tony de Brum walked in at the head of his coalition colleagues. Australia was not among them. It had found itself marginalised as we explained on Friday, by the lingering impact of Tony Abbott’s war on climate policies and renewable energy. Foreign minister Julie Bishop then made a last minute bid to sign Australia up. But it wasn’t until the Coalition had arrived on the floor of the plenary session where France announced – to general acclimation – that the finalised text would be soon released, that Bishop managed to secure her “pin”. By then, it was all but over. Read More here
13 December 2015, Climate News Network, Cold water poured on warming pause. COP21: Scientists say pressure from climate sceptic voices may have led to credibility being given to the mistaken claim that there is evidence of a hiatus in global warming. The so-called, and much debated, hiatus in global warming may never have happened, according to new research The scientists say there is no substantive evidence for a recent flattening of the curve in the increase in global average temperatures: in other words, no pause, no slowdown in global warming. “We suggest,” they add, “that the use of those terms is therefore inaccurate.” But first, and briefly, the story so far. In the 1990s, planetary temperatures rose steadily, reaching a then all-time high in 1998. In the 21st century, temperatures on average continued to rise, but the rate of increase seemed to be lower. Even so, 13 of the 14 hottest years ever have happened this century, and 2014 was thehottest year ever. Denialists, sceptics and contrarians seized on the apparent slowdown and claimed that global warming had stopped. And teams of climate scientists were drawn, like moths to a flame, again and again to the question of whether there really was a slowdown − and, if so, why. Unexplained data They kept doing so because that is how science works: researchers worry away at unexplained data. They evaluate each other’s hypotheses, try to kick them to death, and then propose an alternative. So, in the course of the last three years, scientists have variously accepted that global warming was never going to proceed at a steady, inexorable rate, that some Atlantic Ocean cycle might be at play to damp atmospheric temperatures, or that the heat might have disappeared into the Pacific depths. They have also proposed that an increase in volcanic activity may have masked solar radiation, and that extremes of temperature were on the increase even if the average appeared not to be rising intemperately.

13 December 2015, The Guardian, Malcolm Turnbull lifts Abbott ban on government finance for wind power. Malcolm Turnbull has lifted the ban imposed by Tony Abbott on wind investment by the Clean Energy Finance Corporation (CEFC) before it was officially enacted, even though it remains Coalition policy to abolish the green bank. A spokeswoman for the prime minister said the new CEFC investment mandate – issued by the environment minister, Greg Hunt, and the finance minister, Mathias Cormann – reflected “the Turnbull government’s strong support for renewables and innovation”. “The mandate puts the CEFC’s focus on new and emerging renewables technologies, rather than supporting well-established technologies that are financially viable without government support,” the spokeswoman said. In the wake of the new mandate and the Paris agreement, various stakeholders in the renewable sector were optimistic that the CEFC decision could reboot the government’s relationship with the clean energy industry. The new mandate says: “As part of its investment activities in clean energy technologies, the corporation must include a focus on supporting emerging and innovative renewable technologies and energy efficiency, such as large scale solar, storage associated with large and small scale solar, offshore wind technologies, and energy efficient technologies for cities and the built environment.” Read More here
