Adding to the muddle? The IPCC climate change mitigation report

Gareth at Hot Topic has a neat summary of the key points of the IPCC Working Party 3 report: Climate change mitigation report, which I’ve numbered:

    1. Annual greenhouse gas emissions have risen 10 GtCO2eq between 2000 and 2010, and half of all emissions since 1750 have occurred in the last 40 years
    2. If no further actions are taken to reduce emissions global mean surface temperature in 2100 will increase by 3.7 to 4.8°C compared to pre‐industrial levels
    3. To have a reasonable chance of staying under 2ºC of warming in 2100 means restricting greenhouse gases to 450 ppm CO2eq
    4. Hitting 450 ppm CO2eq will mean “substantial cuts in anthropogenic GHG emissions by mid‐century through large‐scale changes in energy systems and potentially land use”
    5. Typical 450 ppm CO2eq scenarios include overshooting the target and then removal of CO2 by bionenergy with carbon capture and storage (BECCS), though “carbon dioxide removal (CDR) technologies and methods are uncertain and CDR technologies and methods are, to varying degrees, associated with challenges and risks”
    6. The Cancun pledges are not consistent with cost-effective efforts to hit 2ºC, and are more likely to commit the world to 3ºC of warming
    7. The sooner we act, the cheaper overall mitigation will be – as little as 0.06% of annual GDP growth to hit 450 ppm CO2eq.

The “substantial cuts” in point 4 are in fact 41 to 72% by 2050.

In point 5 the cuts required by 2100 are 78 to 118%. That is, the upper bound requires greenhouse gases to be removed from the atmosphere. This will give a “likely” chance of staying below a 2°C increase in temperature over pre-industrial. In IPCC parlance, likely means a 67% or better chance.

This is not “reasonable” as suggested in point 3, it’s reckless.

I’m surprised at the lack of urgency in the report and the modesty of the targets. A 67% or better chance, considering the risks associated with a 2°C increase, amounts to miserable odds. Moreover, as the CSIRO/BOM State of the Climate 2014 report indicated, we are already at 480 CO2eq ppm:

fig13_600

To make matters worse, the chances of staying under 3°C and 4°C are also only rated in the report as “likely”.

Our current situation demands the ambition and urgency called for by Professor John Wiseman, Deputy Director of the Melbourne Sustainable Society Institute at the University of Melbourne:

He concludes that we need more ambition and urgency, both at the national and international levels. The achievement of emission reductions at the necessary scale and speed will require transformational rather than incremental change.

Wiseman goes for a three-phase emissions reduction target regime.

First, a 50% reduction target by 2020.

Second, zero net emissions by 2040.

Third, a carbon draw-down phase to get concentrations below 350 CO2e ppm.

Again, my view:

I applaud his ambition, but, personally, would change the date of the second to 2030 and put a date of 2050 on the third. That is, we should aim for 350 CO2e ppm by 2050.

Professor Kevin Anderson of Manchester University and the Tyndall Centre thinks policy makers are in a muddle about the 2°C target. I’m not sure this IPCC mitigation report helps all that much. Furthermore, I think it misleads rather than promoting a safe climate.

The WG1 science report identified the remaining carbon budget we have to work with to stay below 2°C. Rather than elaborate the carbon budget approach, which I described in the second part of this post, the mitigation report lays out a range of scenarios which involve both overshooting and the use of carbon dioxide reduction (CDR) technologies.

In my view policy makers who concentrate on a less than 95% chance of remaining under the 2°C threshold (I’d prefer 1.5°C) should be immediately sacked and replaced by others more fit to purpose. Scientists writing this report have left the real challenge to the politicians, but by normalising scenarios that lack urgency I fear policy makers will descend into a bigger muddle than ever.

This graph from Malte Meinshausen displayed in the Climate Change Authority report on targets is salutary, considering we are at 480 CO2e ppm:

Stabilisation probabilities_cropped_600

For a safe climate, the line on the graph should be drawn where 2°C intersects with 95%. That would call for greenhouse gas concentrtions of less than 350 ppm. Back in 2008 David Spratt and Philip Sutton in the book Climate Code Red nominated 320 ppm as the target for a safe climate. They called the 2007 Fourth Assessment Report of the IPCC “dangerously conservative”. Not much has changed.

Remember James Hansen nominated 350 ppm not as an end target, rather as an interim goal, whereupon we could decide the next necessary move.

The sad fact is that scientists are not looking at scenarios of 430 ppm or below by 2100. There are too few in existence for the IPCC to summarise.

In describing stabilisation pathways the IPCC collated 900 individual scenarios with target CO2 concentrations (for 2100) of 430 to 720 ppm. They then summarised the scenarios in seven categories (see table SPM1 on page 13 of the Summary for Policy Makers). It’s too large to reproduce here.

The first category, the best we are offered, has the following story line.

To achieve CO2e concentrations of 450 ppm (range 430-480) cumulative emissions from 2011 to 2050 must be in the range of 550 to 1300 GtCO2. By 2100 cumulative emissions must be in the range of 630 to 1180 GTCO2. Please note that the upper bound for 2100 is less than for 2050. This will require a reduction of emissions compared to 2011 of 41 to 72% by 2050 and 78 to 118% by 2100. The resulting temperature change will be 1.5 to 1.7 (1.0 to 2.8) relative to pre-industrial. This will give only a 50% plus chance of staying below 1.5°C and a better than 66% chance of staying below 2°C. There is up to a 33% chance that the temperature will go above 3°C and indeed 4°C.

The temperatures in brackets indicate the uncertainties of how the models relate to reality. In fact at section 6.3.2.6 in the main report we are told that the report’s “probabilistic temperature statements should be regarded as indicative.”

The second category uses a target of 500 ppm (480-530), which only yields a “more likely than not” chance of staying below 2°C, that is >50%. Each category summarises a proportion of the 900 scenarios modelled. Each individual scenario is different depending on whether cuts in emissions are made early or late.

From there it obviously gets worse.

Scientists may be dealing with expected reality, but they have left the real challenge of dealing with the climate to the politicians. Moreover, the action required for a safe climate, as outlined by Wiseman, lies outside the frame of the stabilisation pathways outlined in this report. Approaches such as the International Energy Association’s (IEA) World energy Outlook 2011 highlighting an energy crunch for fossil fuel power generation by 2017 probably has more effect.

Additional reading

Here I’d highlight the article at The Conversation by David Stern on concerns that the IPCC report was censored. This is a misunderstanding of the process. The main report includes a Technical Summary which is prepared by scientists. The Summary for Policy Makers is about a third the length and results from a political filter applied at the end. The material left out, according to Stern, relates to sensitivities and bargaining positions in the current round of UNFCCC talks aimed at striking an international agreement in December 2015 in Paris.

There’s more on the report at Climate Institute, at at Climate Central, at The New Scientist here and here, and at the BBC.

Carbon Brief went wild, producing a dozen posts which I’ve listed here for the record. I’d recommend the first two by Robin Webster for a quick overview, but Ros Donald on fracking and Mat Hope on acronyms may be of particular interest.

1. Pacific winds slow global warming

A team of Australian scientists has found that stronger winds in the Pacific are slowing global warming (paper here, paywalled).

The study found that the winds were churning the Pacific like a washing machine, bringing the deeper colder water to the surface and pushing the warmer water below.

Scientists do not expect the effect to last. Matthew England of the University of New South Wales:

“The phase we’re in of accelerated trade winds particularly lasts a couple of decades,” Professor England said.

“We’re about 12 to 13 years in to the most accelerated part of the wind field.”

There’s more at The Conversation, at Open Mind plus Matthew England at RealClimate and Mike Mann at Huff Post.

The heat is only at a depth of 100 to 300m, so may easily become available to the atmosphere again. Mike Mann thinks the winds and the La Niña effect may be the result of global warming.

2. Animals and plants on the move

The CSIRO have developed a fascinating map showing species on the move due to climate change. I’ve done a screenshot here, but the animated version in the link is best:

species migration copy_cropped

Blue areas indicate significant change and pink areas show “corridors” where animals and plants may be able to move through to more favourable conditions.

“Sink” areas, in orange, show where the movement of land-based species is likely to hit a dead end, by reaching a coastline or mountain range.

Something strange is happening in the middle of Queensland.

3. The year’s weather in 8 minutes

Gareth at Hot Topic has posted a live map of the weather for 2013 as seen from weather satellites. I recommend using the full screen button.

It’s interesting not so much for 2013, but as an overview of how the global system works.

4. Half new energy is green

Fully 44% of all generating capacity installed last year around the world was renewable, says the latest UNEP Global Trends in Renewable Energy Investment, despite a 14% decline in renewables investment, and in new electricity generally.

Europe has cut investment in renewables by 44%. China now leads with $56 billion invested last year.

Shares in clean energy companies rose 54% last year.

5. Germany turns to brown coal

Germany has more wind turbines and solar panels than any other industrialised country, but it also burns more brown coal (lignite) than any other.

As Germany turns off its nuclear power, gas is expensive and a third of it comes from Russia. In these circumstances Germany is turning to lignite to solve the intermittency problem. Because lignite takes 8 hours to fire up plants are run at 40% whether needed or not.

There are three options:

  • storage systems, such as pumped water or hydrogen
  • improving and extending electricity grids so that surpluses can be moved to areas of need
  • organising tariffs to manage demand from big energy users that have intermittent demand.

None of these is being implemented so far to the extent that makes a real difference.

6. Energy use in UK and Germany

Germany generates considerably more energy than the UK, even when population is taken into account.

This graph shows the source of Germany’s power generation for the first quarter of 2014:

Germany_screen-shot-2014-04-30-at-153528_549x170

Nuclear, being phased out over a decade, is a considerable source. Biomass is larger than gas.

Renewable energy is expected to be the main source of electricity generation in Germany by 2030, but policy in both countries is a concern:

In the UK, the Conservative party has recently announced that it will put a cap on onshore wind expansion if it gets into power in 2015. Subsidies for solar power are also likely to be cut, according to media reports – suggesting that Conservatives are increasingly hostile to plans to expand renewables.

In Germany, the government’s putting in place a new renewables plan – possibly in response to concern about rising energy prices. The new rules mean from 2017 energy providers will no longer get guaranteed prices for their power, according to media reports. The effects are unclear, but could slow the growth of German green energy.

7. But then, in Germany at least…

…energy policy is very complex.

In Germany governments attempt to control markets, it seems.

Germany’s energy transition – the Energiewende – has largely been a bottom-up grassroots movement over the past 25 years. Citizens and energy cooperatives account for roughly half the investments. Large utilities are only just now getting on board.

Current changes in policy are aimed at tipping the balance back towards the large corporates, while keeping renewable energy development on track. Policy is also favouring offshore rather than onshore wind.

The article mentions that discussion will now turn to “capacity payments”. I suspect such payments will be necessary to provide backup capacity for intermittency problems, especially if weather forecasts are wrong. For continuity of supply the corporates may have to be paid for unused reserve capacity.

Climate change impacts: IPCC Working Party 2 report

On 31 March the IPCC released its second report in the current series, this one on Impacts, Adaptation and Vulnerability. Follow the links from the report website. We looked at the first report, The Physical Science Basis here, here and here. The third report, Mitigation of Climate Change is now also out, and the final Synthesis Report is scheduled for in September. The series comprises the Fifth Assessment Report.

The IPCC was formed in 1988 and produced assessment reports in 1990, 1995 and 2007. As Graham Readfearn says, the message is the same – we are going to hell in a handbasket – and yes, at that level it’s becoming monotonous.

There is a change, however. It lies in the fact that the impacts of climate change are now all around us. We are not just getting warnings, we are living climate change. The impacts we see locally are integrating into a global pattern, which also includes large-scale transforming events, such as the drying of the Sahel and the loss of sea ice in the Arctic. Increased extreme weather is becoming part of the common experience. In this we are on a path where one in 100 events in any year may become one in three or five. We risk losing whole ecosystems such as the coral reefs where many are in trouble now and all will be by about mid-century, almost certainly. Finally, there is much greater certainty that climate change is happening and about our agency in it. With that certainty comes greater risk, but also opportunity to take action to adapt and to mitigate.

I’ve patterned that paragraph on Greg Picker’s explanation to Steve Austin, while changing the order of the points he made and adding some detail.

The report is organised into two “volumes”, with the first containing 20 chapters, including, for example, one on Human health: impacts, adaptation, and co-benefits and one on Human security. These sectoral reports will provide valuable reference material for years to come.

The second volume comprises 10 “regional aspects” including the ocean.

One of the 10 is on Australasia.

Impacts on Australia

Chapter 25 identifies eight significant impacts for Australia:

  • There is the possibility of widespread and permanent damage to coral reef systems, particularly the Great Barrier Reef and Ningaloo in Western Australia.
  • Some native species could be wiped out.
  • There is the chance of more frequent flooding causing damage to key infrastructure.
  • In some areas, unprecedented rising sea levels could inundate low-lying areas.
  • In other areas, bushfires could result in significant economic losses.
  • More frequent heatwaves and temperatures may lead to increased morbidity – especially among the elderly.
  • Those same rising temperatures could put constraints on water resources.
  • Farmers could face significant drops in agriculture – especially in the Murray-Darling Basin.

University of Queensland marine scientist Ove Hoegh-Guldberg worries that reefs could be severely damaged or disappear by mid-century.

A worst case scenario could see agricultural production reduce by 40% in the Murray-Darling Basin, and in south-east and south-west Australia. The National Irrigators Council says that’s why you have irrigation. However, there is a lot of dry-land farming in these areas and the future average rain is more likely to come in the form of floods when most of the water flows through to the sea.

The above scenarios are risks rather than certainties. However, they add up to a strong chance of dangerous climate change.

Increased certainty

The change in certainty in the attribution of climate change to human activity is conveyed in this image from Dr Jeff Masters’ WunderBlog last year:

IPCC_version95_600

Back in 1990 we saw the possibility of continuing change but what we had experienced at that time could easily have been natural variations subject to reversal. In any case there was low confidence that we could do anything to mitigate. Furthermore, why take measures to adapt, when there was no real certainty?

Now the story has changed dramatically. The pattern and the dominant causes are clear.

Adaptation

From page 27 of the Summary for Policymakers we find a graphic packed with information about various aspects of the impacts of climate change (sorry the graphic is too large to display here!) In the right hand column we find bar graphs showing the present, near-term (2030-2040) and the long-term (2080-2100) risk with hatching to show potential for mitigation through adaptation. The long-term risk is displayed in separate 2°C and 4°C bars.

Little adaptation is possible with Australia’s coral reefs, none at 4°C when the risk becomes very high.

Terrestrial ecosystems losing ice cover in the polar regions are similarly not amenable to adaptation and become very high risk at 4°C.

Loss of crop productivity becomes very high risk at 4°C with little possibility of adaptation. Ditto for heat-related mortality in Asia, North America and, presumably, elsewhere.

Burning embers

The extensive detail in these tables is summarised in a new improved version of the ‘burning embers’ diagram, shown below:

Burning embers_cropped

From this we can readily see that the 2°C ‘guardrail’ marks a fairly arbitrary point on the gradation from dire to downright dangerous.

1. CO2 concentrations passing 400 ppm

Each year the atmospheric concentrations measured at Mauna Loa Observatory in Hawaii surge as spring turns into summer. We are now at the point where earlier each year they surge past 400 ppm, this year as early as March. By 2016 they will probably remain permanently above 400 ppm.

Dr Pep Canadell says crossing the 400 parts per million threshold will make it more difficult and expensive to limit climate change to two degrees.

The second part of this century we need to reduce emissions to zero and on top of it, to be removing carbon dioxide from the atmosphere so that by the end of 2100, we can stay stable under two degrees.

Canadell is head of the Global Carbon Project at the CSIRO.

2. Bio-energy with Carbon Capture & Storage

Speaking of sucking CO2 out of the atmosphere, bio-CCS is the new buzz word (I’ve also seen BECCS). The Climate Institute has released a report by Jacobs SKM Moving Below Zero: Understanding Bio-energy with Carbon Capture & Storage . Their modelling finds that

bio-energy with carbon capture and storage, or bio-CCS using food wastes, sustainable forest biomass, or crop residues, has the potential to contribute significantly to climate change efforts in Australia.

This process could remove and displace about 63 million tonnes of CO2 equivalent (MtCO2-e) annually by 2050, around 1.5 times current emissions from all cars in Australia. As well it would generate 12% of the country’s electricity.

Globally the process could remove up to 10 billion tonnes of pollution per year by 2050, according to the International Energy Agency.

The report may be downloaded from this page (scroll down). Go here for an interview with Malte Meinshausen.

3. Are coal miners responsible for greenhouse gas emissions?

No, said the Queensland Land Court in its judgement on the giant Alpha coal mine project which would dig up about 30 million tonnes of coal a year from the state’s Galilee Basin.

That’s the central fact in Graham Readfearn’s interesting story about what’s un-Australian.

Burning Alpha coal would generate 1.8 billion tonnes of CO2 over 30 years. That’s more than three times Australia’s annual emissions.

4. Abbott calls climate concerns “clutter”

In the lead up to the G20 meeting in Sydney in February, Abbott said

he didn’t want to “clutter up the G20 agenda with every worthy and important cause, because if we do, we will squander the opportunity to make a difference in the vital area of economic growth.”

The post, correctly, I think, sees Abbott as rolling back environmental and climate initiatives as hostile to economic growth, relying for economic impetus on the fossil fuel industry.

Heather Zichal, until recently President Obama’s lead climate and energy adviser, thinks otherwise:

Zichal suggests that focusing on economic productivity could be the sweet spot that Australia could use to balance climate concerns and economic growth goals. Reducing pollution and emissions from power plants and imposing strong energy efficiency measures on transport and infrastructure can boost energy productivity, save money, create jobs, and reduce emissions. “Ultimately, across all economic sectors, energy productivity is the most reliable, cleanest, and cheapest resource,” Zichal said.

Countries have to front up with their revised mitigation plans by April next year ahead of the Paris UNFCCC conference in December, hence leaving climate off the G20 agenda is simply not an option. Abbott has been told, by Christine Lagarde, managing director of the International Monetary Fund, and other powerful players.

One wonders what we will front up with next April. I predict nothing that would make a difference. We’ll see what others are doing and then do as little as possible.

5. Direst Action is a figleaf

Clive Palmer has spotted the figleaf and plans to pluck it away, says Ben Eltham. The Direct Action funding may be part of the budget, which Labor will not vote down. The Government needs no further legislation to enable expenditure, but Abbott can’t get rid of the dreaded carbon ‘tax’ without legislation. When he comes to negotiate that with PUP Direct Action will be on the table.

Eltham is right on the demographics:

While this [having no climate policy in place] may not unduly trouble the climate sceptics on the Coalition backbench, it also removes the chief utility of Direct Action, which is political, rather than environmental. Direct Action has always been used by the Coalition as a handy tool to deflect unwelcome scrutiny of its profoundly anti-environment attitudes. Without it, the Government will find it increasingly difficult to defend itself against charges of destroying the planet.

In the last Nielsen poll the 55+ group was the only one where Abbott had a clear lead, with LNP/Labor/Green at 49/33/10. This should be causing concern for the future of the conservative parties. For the young it was 32/36/26.

6. Direct Action is not scalable

Lenore Taylor points out that while Direct Action may or may not achieve 5% reductions in emissions by 2020, (most experts say, no) the policy is not scalable when the world gets a bit more serious about climate change mitigation.

according to the available modelling, even if Australia spent $88bn from 2014 to 2050 on Direct Action-type policies, emissions would still rise by around 45%. Most economists conclude that big emissions reductions under Direct Action are just not possible.

7. Green groups to use legal strategies

Given the above and the LNP’s farcical attitude to the Renewal Energy Target Review, green groups see lobbying as a waste of time and are increasingly planning legal challenges.

The Australian Conservation Foundation will be targeting voters in marginal electorates to encourage MPs to take climate change seriously. The aim is to change the current race to the bottom to a race to the top.

Reminder: Use this thread as an open thread on climate change.

Climate sceptic heads RET review

The law says that the Renewable Energy Target (RET) should be reviewed every two years, so a 2014 review is mandatory.

The law also says that the review should be undertaken by the Climate Change Authority (CCA), which still exists courtesy of the senate. The CCA in a draft report on the emissions target suggested the current 5% emissions reduction target was not enough if we are to pull our weight in the world. In the text they appeared to favour a 25% target, but recommended at least 15% pointing out also the an additional 4% could be added courtesy of Kyoto credits.

I believe the RET has been one of the more successful factors in restraining emissions.

Giles Parkinson reported two months ago now that the RET Review will be headed by Dick Warburton, a climate change “denier”. Warburton told RN’s AM program that the science was not settled.

I am not a denier, nor a sceptic actually, of climate change per se. What I am sceptical is the claims that man-made carbon dioxide is the major cause of global warming. I’m not a denier of that, but I am sceptical of that claim.

When asked whether he believed renewable energy had its role to play in Australia’s energy mix Warburton replied:

Yes it does. Renewable energy does have a place to play. The review is asking us to look to see whether it is an efficient and effective way of doing it as we’re doing it at the moment.

warburton_250I understand he did overtly oppose carbon pricing.

In my opinion Warburton is a denier. Given the degree of certainty in the science you either accept the science or deny it. There’s no room left for fence sitting. That being said, Warburton had a fine reputation as a businessman leading Dupont’s Australian operations, was used by the Keating government in industry renewal, has been a member of the Reserve Bank board and has had various company board roles.

It has emerged that Warburton has been the subject of an investigation into his role as a former director of a firm involved in Australia’s worst foreign bribery scandal. I would suggest that Abbott has done his due diligence and found him in the clear.

Both Abbott and Macfarlane have been emphasising their concern over renewables contributing to the cost of electricity. A second panelist is Matt Zema, the CEO of the Australian Energy Market Operator. As such he was responsible for a study recently

that found 100 per cent renewables would be possible in Australia, and concluded that the cost of electricity would be little different to business as usual, although AEMO declined to do a full cost analysis.

Greg Hunt parrots his boss’s concerns:

“We are a government that is unashamedly doing our best to take pressure off manufacturing and households through anything that can lower electricity prices,” he said in a theme frequently repeated by the conservative government.

If they are concerned about the future cost of electricity they could begin by looking at the policy of privatisation, found to be “a dismal failure” by Professor Quiggin.

A third panel member, Shirley In’t Veld, is the former head of WA government owned generation company Verve Energy which

has had a history of snubbing renewable energy and chose instead to invest in the refurbishment of the ageing Muja coal-fired generator. The refurbishment has proved to be a financial disaster, with the WA government admitting that nearly $300 million had gone down the drain.

The fourth member is Dr Brian Fisher, the former long-term head of ABARE until he left for private enterprise in 2006 to head up a fossil fuel lobby group, Concept Economics. At ABARE he gained notoriety for his positions on climate policies and is a noted free-market hardliner. Under Fisher:

ABARE was responsible for the infamous “MEGABARE” model that made Australia a laughing stock in connection to the Kyoto negotiations.

Sounds like a merry crew, Abbott’s idea of ‘balance’, and bound to add to the climate recalcitrance now so common in the Anglo-Saxon world.

There is a question as to whether the LNP deliberately lied and misled the public prior to the election. The SMH cites specific bi-partisanship as late as July 2013. Labor’s view:

“At every possible point, they tried to assure the community that there was a bipartisan consensus around the RET, and therefore the growth of renewables,” Labor climate change spokesman Mark Butler says. “What’s clear now is that it was just an utter falsehood.”

Albo:

“They made it very clear; Greg Hunt staked his reputation on the maintenance of the renewable energy target,” he told said in the island state of Tasmania.

“It’s important for jobs. It’s important in terms of positioning Australia as a clean energy economy into the future.

“We’ll wait and see what they do but we’ll be holding them to account,” Mr Albanese said.

Update: Giles Parkinson tells how the Warburton Review is getting down to business today by looking at what the RET of 20% means. Presently it is a number – “41,000GWh of large-scale developments and an uncapped amount of small-scale generation”. It seems that more than half of that number can be made to disappear by changing definitions.

Climate Change Authority review

In late February the Climate Change Authority published a Draft Report of its Targets and Progress Review.

The full draft report (all 265 pages) is downloadable from the first link above. Unfortunately I don’t have time to read all of it. Clive Hamilton at The Conversation has written an excellent overview. Continue reading Climate Change Authority review

1.Three reports

First, the Climate Change Authority released a Draft Report of its Targets and Progress Review.

I have a draft post in the bin, which I’ll publish after Easter. Labor are likely to adopt the enhanced targets it recommends, whereas the LNP have confirmed they won’t go beyond 5% by 2020.

Second, I’m working on a post on the IPCC’s second report in the current series, released on 31 March Impacts, Adaptation and Vulnerability. To get a head start you can follow the links from the report website.

I should be able to finalise the post for the week after Easter.

Third, the Summary for Policymakers of the IPCC’s third report Climate Change 2014: Mitigation of Climate Change was released on Monday. I hope to tackle it over Easter, aiming for publication the second week after Easter. The ABC has comment: politicians and Frank Jotzo and John Connor. The Carbon Brief has a lot of useful material.

2. The cost of mitigation

The IPCC mitigation report puts the cost of action at 0.06% of GDP, but calculating the cost is complex, especially when looking at the damage caused by doing nothing.

Researchers Rosen and Guenther find that the economic modelling is not possible, there are too many variables and too many unknowns.

Yet crisis trumps uncertainty, we have no real choice but to act.

3. Trouble in the vineyards

Early ripening is becoming a huge problem for growers and wineries.

growers say they’re having trouble processing their crop because it’s ripening too quickly.

Researchers are blaming climate change, with warmer conditions and drier soils accelerating the ripening process.

4. Microbes cause Permian–Triassic extinction?

The Permian–Triassic extinction event, commonly known as the Great Dying, was responsible for the extinction of roughly 90% of all life on Earth.

According to new research at MIT the event may have been caused by microbes.

The team’s research indicates that the catastrophic event was in fact triggered by the tiniest of organisms, a methane-releasing microbe called Methanosarcina. New evidence suggests that at the time of the extinction, the microbes appeared in massive numbers across the world’s oceans, spreading vast clouds of the carbon-heavy gas methane into the atmosphere. This had the effect of altering the planet’s climate in a way that made it inhospitable to most other forms of life inhabiting Earth at that time.

5. Land clearing returns to Qld

According to The Wilderness Society the Queensland Government has approved the clearing of 30,000 hectares at Strathmore Station in the Gilbert River catchment in the Gulf country, which will add the equivalent of 4.2-6.6 million tonnes of carbon dioxide into the atmosphere, the same as running up to another 2.6 million cars on our roads.

Strathmore wants to clear another 70,000 hectares. Together with another proposed Gilbert River project, IFED’s so-called Etheridge mega farm, the two schemes would clear and flood 200,000 hectares of land.

That would be like bulldozing a 10km wide strip for 200km.

6. Instruments of persuasion

Dr Rod Lamberts of the Australian Centre for Public Awareness of Science at the ANU says it’s time to dump science and facts as instruments of persuasion in favour of advertising and marketing. He says we need to appeal to people’s emotions, which will

have a stronger effect than trying to appeal to their brains via some kind of, you know, fact channel.

But please note, the facts are needed to support the campaign:

If the goal is to affect change, then I believe we need to step more into the realms of advertising and marketing and so on, in terms of delivering messages that are supported by what the science is telling us, but don’t have the science in those messages. (Emphasis added)

Jane Caro agrees on the need for a different approach:

Facts have never changed anyone’s mind about anything, sadly. It’s very hard for scientists to understand this, because they’re highly rational people, but in actual fact, no-one has ever been rationalised out of a belief.

There are only two things that change people’s attitudes and behaviour, particularly their behaviour, and they’re two emotions, and they’re hope and fear.

Again, facts and the science are surely needed to rationalise a changed belief. Beliefs need reason to support them.

Who mounts and pays for an advertising and marketing campaign? We look to governments, but in Australia they are the actual problem.

7. Direct Action less popular than the price on carbon

Meanwhile Essential Media Communications have done a survey of opinion that shows Direct Action distinctly less popular than the price on carbon. In terms of age, there is a tipping point beyond which the doubters predominate and it’s age 55. Abbott’s climate policy may come back to bite.

as the flat-earthers take control of the Federal Government, more Australians than ever have come to the conclusion that the Earth is in fact round.

Changing our policymakers seems the best way home but then Labor needs to offer more than tokenism. In my opinion Labor politicians should be the prime target group. The current mob won’t change without a spell in opposition and transformational ideological renewal.

Reminder

Use this as an open thread for climate topics.

COMMENTS ON QCA REPORT ON FEED IN TARIFFS

This post was published previously in PragmatusJ (my reference blog). It explains how the QCA came up with a “fair and reasonable” Qld FIT of 8 cents/kWh and the inherent problems of letting politicians or bureaucrats set the FIT.
The following are some brief comments on the Qld Competition Authority (QCA) report “Estimating a Fair and Reasonable Solar Feed-in Tariff for Queensland (March 2013) Table numbers are QCA report table numbers.  Key findings were:
The report admits that it was only concerned with being fair to the retailers, not rooftop solar PV (RTS) owners, power generation companies or consumers.  By implication, the QCA was also committed to defending the payments made to power distributors.
  1. When calculating the “fair” FIT the QCA managed to find excuses for not including most of the savings associated with the use of RTS.  This made an enormous difference.  If these savings are included, the FIT would have to be above 100 cents/kWh before RTS stopped reducing the power bills of Qld householders who don’t have RTS.  The QCA exclusions reduced this figure to a measly 8 cents/kWh.
  2. The difference in estimates highlights the problems associated with having bureaucrats or politicians set the feed in tariff.  It also highlights the problem of determining the FIT on the basis of the effect on household power bills.
  3. This post is not advocating that the FIT be raised to $1.00 kWh.  It is suggested that auctions or some other market based system be used to set the FIT.

US NAVY PRODUCING FUEL FROM SEAWATER

The US navy has been investigating the production of fuel from seawater using electricity from ship’s nuclear power systems for a number of years.  This process would allow aircraft carrier task forces to stay at sea longer without depending on vulnerable fuel tankers to keep the planes flying.  The navy has now announced that they have successfully used the fuel from their pilot plant to fly a plane with an internal combustion engine.  (Well, OK a model mustang.)

The process used involves electrolysis of sea water to produce CO2 and hydrogen followed by a catalytic reaction to produce hydrocarbons.   There is nothing radically new here.  Hydrogen has been produced commercially using electrolysis for a long time.  There are also well established commercially available processes for converting mixtures of hydrogen and nitrogen or hydrogen and CO2 into a range of useful chemicals and fuels.  My guess is that most of the effort taken by the US navy has been focused on developing a process that could fit into a small part of an aircraft carrier.

The potential of these types of development go well beyond the needs of the US navy.  Think about it: Unless there is an amazing breakthrough, renewable power plus batteries are not going to be able to deliver 100% renewable transport.  Renewable power + batteries is not going be suitable for long distant flights, travel in the Australian outback or long distance sea travel.  There is a need for energy intensive transportable fuels to cover these needs.

Bio-fuels are not the answer.  Diversion of land to the production of bio-fuels is already causing starvation of people in some countries as well as damage to the environment.  (Think jungle clearing for palm oil production.)  In addition, the production of bio-fuels is vulnerable to climate change and pests as well as posing potential problems if the organisms used escape into the wild.  What is needed are low impact renewable fuels produced by inorganic processes such as the US Navy process mentioned above.

The end of coal?

This post started out as four related items in Climate clippings. When a fifth showed up I decided to extract them and put them in a separate post. Hence it is a collection of opinions and perspectives rather than an analysis of the future of coal as such. Still, a message seems to emerge.

BHP calls for carbon pricing

Believe it or not Andrew Mackenzie, CEO of BHP Billiton, has called for a price to be put on greenhouse gas emissions to address the threat of global warming.

Talking in Houston Texas on the future of fossil fuels and carbon emissions Andrew Mackenzie said BHP needs to think carefully about controlling its carbon emissions. He wants BHP to lead the way. BHP is the world’s largest mining company and the third biggest company in the world.

Beyond coal the company is also a major player in shale gas in the USA, investing a cool $US20 billion in 2012.

Mackenzie was on message about ‘clean coal’, spruiking the virtues of carbon capture and storage (CCS).

Rio weighs in

Rio Tinto’s head of energy, Harry Kenyon-Slaney, also weighed in saying “Idealistic discussions” about climate change should be abandoned and Australians should recognise that coal will remain an important energy source for decades.

Coal will continue to “do the lion’s share of heavy lifting” to meet energy demand, he says.

Rio has invested $100 million in carbon capture and storage.

Martin Ferguson, now an adviser to the Australian Petroleum Production & Exploration Association:

stepped up criticism of the Coalition government’s emissions-reductions policies and called for the watering down of the renewable energy target, which he said was undermining the national electricity market.

Tristan Edis comments

Tristan Edis comments on Rio Tinto’s clean coal idealism.

He reckons CCS would be great if you could also retrofit it to existing coal-fired power stations, implement it at large scale and a reasonable cost and start doing it by, say, 2025.

The Australian Coal Association instituted an industry-funded initiative to progress zero-emission coal with a levy and created ACA Low Emissions Technology Ltd (ACALET) to undertake initiatives. Unfortunately from 2012-13 the requirement to pay the levy was suspended and ACALET is now concentrating on promoting the use of coal in Australia and overseas.

Edis reports that Industry Minister Ian Macfarlane seems to be willing to acknowledge that carbon capture and storage is a pipedream.

One senior Liberal referred to it as ‘vaporware’ (new computer software promised by companies to be delivered in the future that never eventuates but scares off competing software development).

The end of coal?

Paul Gilding has called the end of coal and the dawn of renewables, especially solar.

He believes the fossil fuel industry live in a delusionary analytical bubble, convinced of their own immortality. They are about to be swept away. Markets can be brutal.

The top 20 European utilities have lost $600 billion in value over the past 5 years.

Tesla, presumably because it makes electric vehicles (see also below), is now worth more than half GM although GM makes 300 times as many cars.

HSBC’s Global Solar index rose 65% last year and is already up 23% in 2014.

Underground coal gasification

Trials are underway or planned in diverse parts of the world in burning in situ coal that can’t be mined, according to an article by Fred Pearce in the New Scientist (paywalled). The process is underground coal gasification (UCG).

The potential is enormous, with enough coal available to supply the world with energy for 1000 years. For example, 70% of the coal in the UK has never been mined. One company has a licence to prospect for UCG sites beneath more than 400 square kilometres of the North Sea.

The attraction of UCG is not just power production. The process produces methane, carbon monoxide, hydrogen as well as CO2. The Brits see potential to use these chemicals as feedstock to revitalize their industrial chemicals industry. The article lists the following uses:

  • Gas to electricity Power stations can burn methane to produce electricity for the grid
  • Gas to chemicals Hydrogen, methane and CO all have value as feedstock for the chemicals industry
  • Gas to liquid Methane can be liquefied (LNG) for storage or transport, or the CO and hydrogen converted through the Fischer-Tropsch process to synthetic diesel fuel for vehicles
  • Gas to tech Hydrogen can provide an alternative transport fuel

CO2 can be reinjected into the void created by the burnt coal.

The article refers to a 2007 MIT study which found that commercial CCS was unlikely before 2030. Undaunted Myles Allen, an Oxford University climate scientist, reckons that CCS is the “only practical way forward”.

Christiana Figueres is hopeful

Christiana Figueres, Executive Secretary of the UN Framework Convention on Climate Change (UNFCCC), points to 60 countries with 500 pieces of climate legislation, and is confident that an international climate change agreement will be delivered on time in 2015. She looks forward within 20 years to the time where everything new we do will be carbon neutral.

She does see a need for research into energy storage – batteries – and into CCS.

It is only with marketable CCS that we will be able to use the fossil fuels that we need. Storage and CCS would be my top two choices for technology investment.

If so someone, for example BHP and Rio, get cracking.

Meanwhile…

Meanwhile

Investment bank Morgan Stanley says it has been overwhelmed by the response to its recent analysis which suggested that the falling costs of both solar modules and battery storage presented a potential tipping point that would encourage huge numbers of homeowners and businesses in the US to go off grid.

And Tesla is building a $5 billion ‘gigafactory’ for battery production, then providing an

emergency power service by monitoring the power levels in home batteries and delivering replacement batteries in the event home batteries run out of power.

Someone should tell Andrew Mackenzie and Harry Kenyon-Slaney they’ll need to shake a leg with CCS. Schumpeter’s creative destruction seems to be at work in the energy industry.

Update: Murray Energy, the largest independent coal producer in the US, is suing the EPA for not taking into account job losses when formulating emissions regulations.

The folly of Abbot point and Galilee Basin

This post was written back when the issues of Abbot Point expansion and the dumping of waste in the Great Barrier Reef Marine Park area were current. Now the Queensland Land Court has recommended the State Government reject the multi-billion dollar GVK-Hancock Alpha Coal project in the Galilee Basin. The decision is a non-binding recommendation to the State Government. If they go ahead, conditions have been suggested.

Impact on groundwater was the main concern of local landowners.

It looks to me as though this decision will not in the end impede the construction of the mine. Nevertheless there are concerns also about the economic viability of both the coal mines and the port expansion, as I discuss in the post.

Abbot Point and the Marine Park

Recently the Abbot Point port expansion proposal has caused a great deal of controversy because of the proposed dumping of 3 million tonnes of sludge within the Great Barrier Reef Marine Park area. The contention is that the Great Barrier Reef Marine Park Authority (GBRMPA) initially found against the dumping. In January this year GBRMPA approved the dumping.

Professor Russell Reichelt, chair and chief executive of the Great Barrier Reef Marine Park Authority, makes clear at The Conversation that the material to be dumped is not toxic and while the Authority would prefer placing dredge material on land, “providing it does not mean transferring environmental impact to sensitive wetlands connected to the reef ecosystem”, they are comfortable with the proposed plans.

The material to be dumped is about 60% sand and 40% silt and clay, similar to what you would see if you dug up the site where the material is to be relocated. The target area is a defined 4 square kilometre site free of hard corals, seagrass beds and other sensitive habitats, about 40 kilometres from the nearest offshore reef.

The Marine Park itself is about the size of Italy:

Marine Park_ jdpx6f2d-1393566267_600

In a comprehensive discussion of the Abbot Point expansion and the Galilee Basin Radio National’s Background Briefing implies that the Abbot Point expansion will not be supervised. The story is told of how in the previous expansion contractor John Holland effectively ignored environmental regulations and was fined a token $195,000 as a result. Professor Reichelt specifies what is to happen this time:

we will have a full-time staff member from GBRMPA located at the port to oversee and enforce compliance during dredge disposal operations. This supervisor has the power to stop, suspend or modify works to ensure conditions are met.

In addition, an independent technical advice panel and an independent management response group will be formed. Membership of both these bodies will need the approval of GBRMPA.

Importantly, the management response group will include expert scientists as well as representatives from the tourism and fishing industries, and conservation groups. Together, GBRMPA and those other independent scrutineers will be overseeing the disposal, and will have the final say — not North Queensland Bulk Ports, which operates Abbot Point, or the coal companies that use the port.

This overview is worth quoting:

Our recent assessments show the dominant risks to the health of the reef are the effects of climate change, excess sediment and nutrient run-off (such as from widespread floods), outbreaks of coral-eating starfish, extreme weather, and some types of fishing.

Coastal development such as ports are assessed as significant but local in their effects.

The effects of climate change.

Watching Greens Senator Larissa Waters debate the Abbot Point expansion with the relevant Qld government minister was like being in an alternate reality. There was no mention of the climate effects of the coal to be exported, no mention of the warming and ocean acidification impact on the reef.

No mention of the impact of the monster mines on the local environment, the use of local aquifers, of the possibility of toxic runoff into the river systems and flood plains the the southwest, the Channel Country and Lake Eyre. As I said last year in Galilee Basin coal: a vision splendid or a kind of madness?:

Water is in fact a considerable issue, as the area has only 400 to 500mm rainfall pa, seasonal and highly variable. Artesian aquifers and water from coal seam gas are being considered. Pastoralists are naturally worried as are environmentalists. The area can be subject to heavy rains which ends up with a toxic brew from open-cut mines being pumped into water courses. The basin drains towards Lake Eyre, (now officially known as Kati Thanda–Lake Eyre).

This image is from an organic beef producer and their enthusiasm has expanded the area to include the whole Simpson’s Desert, but it gives an idea of the part of the country we are talking about:

Channel-Country

Moreover the railway line or lines will cut across grazing lands on expansive flood plains, making water movement highly problematic with heavy rain.

Economics of the mining projects

Mercifully both projects look wildly uneconomic. The Background Briefing story quotes a UBS commodities analyst who says that for the Galilee Basin to be profitable the coal price would have to be around AU$110 per tonne. Their long term estimate is $80 per tonne. The program saw India rather than China as being the most prospective customer. India is running out of coal that can be mined, but the current price there is about $23 per tonne (I presume US$). They need electricity for hundreds of millions who rely on wood or cow dung for cooking and heating, but not at any price.

John Quiggin has two posts about companies pulling out and the shaky economics of both projects:

Following a similar announcement last week by Lend Lease, and earlier announcements by BHP Billiton annd Rio Tinto, mining company Anglo American has withdrawn its proposal to take part in the expansion of the Abbot Point coal terminal. That leaves only two proposals, both from Indian companies owned by billionaire entrepreneurs reminiscent of Bond, Skase and other Australian heroes of the 1980s. Both Adani and GVK are heavily indebted conglomerates of the type that invariably emerge when money is cheap, and mostly collapse when the tap is turned off.

It’s not surprising that these companies have not yet abandoned their bids. Doing so would involve booking huge losses on their mining prospects in the Galilee Basin. But, it’s hard to believe anyone is going to lend them the billions required, not just for the port expansion, but for a 500km rail line and the mine itself. The price of coal is well below the level required to cover the costs of extraction and transport, let alone to provide a return on capital. And if Adani and GKV don’t build the rail lines, the development of the entire Basin will grind to a halt.

Here’s hoping!

Update: Mark Colvin discusses the economics of the mine with the ABC’s business editor Ian Verrender, confirming concerns.
