During November 2013, a 3-part series on nuclear waste will be progressively published on BNC, authored by Geoff Russell. Part 1: bravenewclimate.com/stayin-alive-gene-pool-p1Part 2: bravenewclimate.com/stayin-alive-gene-pool-p2Part 3: bravenewclimate.com/stayin-alive-gene-pool-p3In this comprehensive and fascinating review, you will be taught to distinguish science fact from science fiction on the many vexed issues surrounding radiation, including cancer risks, genetic and physical mutations, and the biological legacy of exposure to acute or chronic ionising radiation. Read on (and tell us what you think). You may well be surprised with what you discover. This BNC Discussion Forum thread is for the comments related to all 3 of the posts in this series.

Anon (anonposter)- I was mass deleting over 2000 accounts that had zero post counts after a week or more (they are virtually all SPAM accounts, based on the user/email combos and often associated weblinks), and I inadvertently deleted your account too - very sorry! (alas, your name was hard to pick out from the bogus ones...) Now, I can't restore your account directly via ProBoards admin, it seems, but apparently if you re-register with the same information (user, email) then all your posts should be automatically re-linked to that account. Once you've done that, I will then restore your post count to 524 (what it was at, when the disaster happened ) My sincere apologies for the mishap.

A post has been published on BraveNewClimate. Link here: bravenewclimate.com/new-critique-aemo-100pc-renewTed Trainer writes: "The AEMO report concludes that 100% of Australian electricity demand could be met by renewable energy sources. The claim is far from established and highly challengeable because some of the assumptions etc. are implausible and not likely to be borne out, and some crucial factors haven’t been taken into account. Intermittency has not been dealt with at all satisfactorily, embodied energy costs seem not to have been considered, and it is admitted that some major costs have not been included. It is clear that a thorough study would have arrived at an annual capital cost in the early years of construction that was several times the sum claimed. The main issue with renewables is not whether it is technically possible for them to meet total demand – it is whether the large amount of redundant plant needed to deal with intermittency could be afforded."

Thanks, I deleted the offending post - these types of subtle SPAM can get through they system and need individual attention!
I think I got rid of them all - there were 7 individual posts that had resurrected old threads. Let me know if you find any others. Very annoying.

A post has been published on BraveNewClimate. Link here: bravenewclimate.com/renewable-electricity-nirvanaBack in 2011, the federal Department of Climate Change and Energy Efficiency commissioned the Australian Energy Market Operator (AEMO) to investigate two future scenarios in which the National Electricity Market was fuelled entirely by renewables ... as defined by the Department. An essential component of AEMO's 100 percent renewable solution involves the annual transport of 50 million tonnes of plant material from farms, native forests and plantations in what can only be described as a massive soil mineral mining operation. Log, slash, truck and burn. Geoff Russell explores the implications of this 'green' scenario... This BNC Discussion Forum thread is for the comments related to this BNC post.

What 'howler', Jim? Are you arguing that you didn't divide by 8.76 instead of multiplying in your table (creating a 77-fold distortion), or that you didn't blatantly cherry pick your numbers, or that you aren't using exactly the same slanderous methods of the climate change denialists, including trying to discredit respected and highly credentialed researchers with the Steve Milloy inspired 'junk science' epithet?

A new guest post by Martin Nicholson has been published on BraveNewClimate. Link here: bravenewclimate.com/100pc-renew-study-needs-makeoverThe Australian Energy Market Operator (AEMO) has released its draft report titled 100 Per Cent Renewables Study – Draft Modelling Outcomes. The study was commissioned by the Department of Climate Change and Energy Efficiency (DCCEE) to explore future scenarios for the National Electricity Market (NEM) fuelled entirely by renewable resources. What are the principal conclusions we can draw from this work? How feasible is the 'all renewables' dream for Australia, and how much will it cost?

A new guest post by Graham Palmer has been published on BraveNewClimate. Link here: bravenewclimate.com/household-pv-primary-le-powerWith declining system costs and assuming a short energy payback period, photovoltaics (PV) should, at face value, be able to make a meaningful contribution to reducing the emission intensity of Australia’s electricity system. But will it? Graham Palmer takes a critical look at this key question. This BNC Discussion Forum thread is for the comments related to this BNC post.

A new post has been published on BraveNewClimate. Link here: bravenewclimate.com/counting-hidden-costs-of-energyIt is often claimed that introducing variable renewable energy resources such as solar and wind into the electricity network comes with some extra cost penalties, due to “system effects”. These system effects include intermittent electricity access, network congestion, instability, environmental impacts, and security of supply. Now a new report from the OECD titled System Effects of Low-Carbon Electricity Systems gives some hard dollar values for these additional imposts. The OECD work focuses on nuclear power, coal, gas, and renewables such as wind and solar. Their conclusion is that grid-level system costs can have significant impacts on the total cost of delivered electricity for some power-generation technologies.

A new post has been published on BraveNewClimate. Link here: bravenewclimate.com/81000-truckers-for-solarThe World Wildlife Fund (WWF) recently released its World Solar Atlas report reckoning that the world's entire projected needs in 2050 of something beginning with "e" could be met with solar panels on less than one percent of the planet's surface. But how realistic is this in the real world, and what are the other options that WWF ignored? In a guest post, Geoff Russell asks the hard questions.

We were addressing ecological tipping points in the terrestrial realm. We suggested that marine systems are more connected and ocean acidification was a plausible global TP. There are a number of tipping elements for the climate system that are geophysical in origin that are also plausible. Not for biomes, however.

A new post has been published on BraveNewClimate. Link here: bravenewclimate.com/ecological-tipping-pointsIn a paper published last week in Trends in Ecology and Evolution, I (Barry Brook) and my colleagues argue against the idea of an ecological global-scale “tipping point”. In this BNC post, I outline the paper’s core argument, while Professor Corey Bradshaw (not an author on the study) explains what it means for conservation practice.

A new post has been published on BraveNewClimate. Link here: bravenewclimate.com/two-decades-and-countingWhile the French have been generating electricty for ~80 grams of CO2 per kWh for two decades, the Germans are still putting out ~450 grams/kwh and Australia is close to world’s worst practice ~850 grams/kwh. The anti-nuclear movement has corrupted green thinking and cost us two decades and thousands of lives in the battle to avoid dangerous climate change … and counting. So says guest poster, Geoff Russell. Do you agree? This BNC Discussion Forum thread is for the comments related to this BNC post.

A new post has been published on BraveNewClimate. Link here: bravenewclimate.com/energy-policy-substance-wins-over-styleThere’s a gradual, but a rising tide of rational, enviro-progressive scientists out there who are committed to solving some of the world’s biggest problems. Many of these problems involve touchy subjects, including ways to reduce poverty while improving or maintaining high standards of living elsewhere, the means for ‘sustainable’ electricity generation, and how to limit the human population’s over-consumption and over-production. Inevitably, however, many well-intentioned, but grossly misinformed environmentalists (‘enviro-conservatives’?) object to technical solutions based on emotional or ideological grounds alone. As self-professed enviro-progressives (but also scientists who base decisions on evidence, logic and balancing trade-offs as part of our everyday work), we hope to reduce this backlash by providing the data and analyses needed to make the best and most coherent decisions about our future.
