17 December 2015, The Guardian, There is a new form of climate denialism to look out for – so don’t celebrate yet. After the signing of a historic climate pact in Paris, we might now hope that the merchants of doubt – who for two decades have denied the science and dismissed the threat – are officially irrelevant. But not so fast. There is also a new, strange form of denial that has appeared on the landscape of late, one that says that renewable sources can’t meet our energy needs. Oddly, some of these voices include climate scientists, who insist that we must now turn to wholesale expansion of nuclear power. Just this past week, as negotiators were closing in on the Paris agreement, four climate scientists held an off-site session insisting that the only way we can solve the coupled climate/energy problem is with a massive and immediate expansion of nuclear power. More than that, they are blaming environmentalists, suggesting that the opposition to nuclear power stands between all of us and a two-degree world. That would have troubling consequences for climate change if it were true, but it is not. Numerous high quality studies, including one recently published by Mark Jacobson of Stanford University, show that this isn’t so. We can transition to a decarbonized economy without expanded nuclear power, by focusing on wind, water and solar, coupled with grid integration, energy efficiency and demand management. In fact, our best studies show that we can do it faster, and more cheaply. Read more here

17 December 2015, Renew Economy, Tasmania switches gas fired generator back on as hydro runs low. Hydro Tasmania has announced that it will re-assemble and restart its Tamar Valley gas-fired generators for the first time in 18 months in response to the driest spring in the state ever recorded. The state-owned company, which powers the local grid mostly with hydro and wind energy, and exports some of that to the mainland, says hydro levels have sunk to around 25 per cent after the driest September to November period on record, although better inflows have been received in recent weeks. It says that restarting the Tamar Valley gas generators, which operate as a combined cycle gas turbine (broadly equivalent to base load rather than peaking) makes “good commercial sense”. Presumably because it allows the limited hydro to be conserved for higher pricing peaking events. The fall in hydro reservoirs is not just a problem in Tasmania. Earlier this year, Snowy Hydro decided to pay $234 million for the Colongra gas-fired power plant in NSW. Even though the plant had only operated for a total of 300 hours in 5 years, and rising gas prices basically priced it out of the market, Snowy Hydro bought the gas peaking plant as an insurance against the risk of declining water levels. Its gas plants in Victoria performed a similar role in the last drought in that state. Read more here
14 December 2015, Renew Economy, Hidden gem in Paris deal condemns coal to early demise. When France foreign minister Laurent Fabius brought the gavel down on Saturday night and declared the Paris Agreement on climate change action was sealed, the reaction was almost immediate. Within the conference hall it was greeted with cheers, hugging and great emotion. Outside, the agreement to cap temperature rises “well below 2°C” and as low as 1.5°C signalled a remarkable achievement that had one major implication: the end of the fossil fuel era is nigh. ….But if that is what the fossil fuel industry and the Coalition government are really thinking, then the evidence suggests that they are kidding themselves. One little gem, alerted to me by the Potsdam Institute’s Malter Meinshausen (on the dance floor of the COP after party of all places) puts the agreement in a new perspective. It is this paragraph, article 17, in the decisions text of the deal: “Clause 17. Notes with concern that the estimated aggregate greenhouse gas emission levels in 2025 and 2030 resulting from the intended nationally determined contributions do not fall within least-cost 2 ̊C scenarios but rather lead to a projected level of 55 gigatonnes in 2030, and also notes that much greater emission reduction efforts will be required than those associated with the intended nationally determined contributions in order to hold the increase in the global average temperature to below 2 ̊C above pre-industrial levels by reducing emissions to 40 gigatonnes or to 1.5 ̊C above pre-industrial levels by reducing to a level to be identified in the special report referred to in paragraph 21 below”; OK, now for a quick translation. The world currently emits around 50 gigatonnes of greenhouse gas emissions a year. Even if all the pledges put together by 186 nations before and during the Paris climate talks were enacted, these emissions would grow to around 55 gigatonnes of GHG emissions a year by 2030. But to meet the 2°C target, the world will need to reduce those emissions to 40 gigatonnes a year. And to reach that level, they are likely going to have to reverse direction before 2020. What’s more, if the world does move to that aspirational goal of capping temperatures to 1.5°C above pre-industrial levels, then it is going to have to move a lot faster, and a lot more dramatically than that. That trajectory will be outlined by a new IPCC report due in 2018. Read More here
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
