Climate clippings_175 This edition contains a miscellany from the absolutely central scientific issue of climate sensitivity to adaptation in Bangladesh.

1. Sense about climate sensitivity

The fourth IPCC report in 2007 estimated that the planet will warm between 2 and 4.5°C warming in response to a doubling of the amount of CO2 in the atmosphere, with a best estimate of 3°C. Since then a number of studies suggested a lower sensitivity, leading the IPCC’s fifth report to extend the range to 1.5°C at the lower end and omit a best estimate entirely.

Dana Nuccitelli reports on a new paper by Kummer & Dessler which shows that recent studies suggesting an insensitive climate are flawed. Without going into the detail they converge on a value around 3°C.

2. CO2 fertilization won’t slow global warming

Some contend that increased CO2 in the atmosphere will enhance plant growth leading to an increase in soil carbon. A study of this issue found that any such gains were offset by increased microbial activity in soils. Along the way the researchers found that soil carbon was less stable than previously thought.

3. Bangladesh uncovers the crippling cost of climate change adaptation

Bangladesh_viewimage_500

Bangladesh has found the cost of climate change adaptation quite crippling in a new report.

They are spending $1 billion a year, 6-7% of their annual budget, on climate change adaptation. Only a quarter comes from aid.

The irony of the finding will be lost on few people: the average European citizen emits as much carbon in 11 days as the average Bangladeshi in an entire year. Yet it is the government and the people of Bangladesh who are expected to pay for the escalating costs.

Within the country it is the poor who are most severely affected.

After the report Bangladesh sees climate adaptation expenditure as central to their development.

4. Deutsche Bank rules out funding for controversial Abbot Point coal terminal

Deutsche Bank:

said it would not finance an expansion without the assurance of both the Government and UNESCO that it would not damage the Great Barrier Reef.

“We observe that there is no consensus between UNESCO and the Australian Government regarding the expansion of Abbot Point,” it said.

“Since our guidance requires such a consensus as a minimum, we would not consider a financing request.”

Thanks to John Davidson for the heads-up.

5. Onshore wind cheapest form of power


In Europe, that is
according to Portugal’s EDP, which has around 24GW of generation, of which around 8.7GW is in onshore wind.

CCGT is baseload gas.

John D has more detail at Climate Action 04.

The same article tells us that Keith DeLacy, former Qld Labor treasurer who would do just about anything to turn a buck, said on the front page of the Oz that renewables had “no place in a modern society”.

Meanwhile economist Jeffrey Sachs, advisor to UN secretary general on the Millennium Development Goals, is in Australia telling us that we can’t mine all that coal unless we invest in carbon capture and sequestration technology. We just need to get serious:

Put in real money, probably $20 to $30 billion I would say, minimum, to get scaled, serious demonstration programs working in China, in India, in Australia, in Canada, in the United States and to test the geology and the engineering of this technology.

Sachs is a man who thinks big!

6. EU’s energy strategy

Not surprisingly, the EU has been taking another look at its energy security strategy in view of the political instability to their east.

The EU imports over half the energy it consumes at a cost of more than €1 billion per day. Two-thirds of its gas is imported, with nearly a third coming from Russia. Half of that is transported via Ukraine.

Russia has already twice pulled the plug on gas supplies to Europe arriving via Ukraine, in 2006 and 2009.

The bottom line is that there will be a continued dependence on Russia for the foreseeable future:

The EU energy security strategy doesn’t look like it’ll take a rifle to that Russian bear just yet. But with a tweak to address vulnerability here and a spotlight on energy dependence there it may just help the EU avoid a mauling – and drive an ambitious EU 2030 climate and energy deal too.

Shale gas and nuclear energy are being left as options that member states can explore if they wish.

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

Soil carbon and direct (in)action

Last week on the 7.30 Report we were treated to a debate between Mark Butler, the climate change minister and his Opposition counterpart, Greg Hunt, that just did not work. Leigh Sales tried a hard-edged questioning style, but unfortunately did not come close to being familiar with the topic. So large parts of the LNP agenda were unaddressed, such as their dismantling of the institutional framework of the the Climate Commission, the Climate Change Authority, the incorporation of the Climate Department into the broader environment department and the dismantling of the Clean Energy Finance Corporation.

One issue canvassed was the sequestration of carbon in soil, which comprises a large part of the LNP’s mitigation strategy.

Mark Butler said the cost of such abatement was higher than previously thought, the potential for sequestration less and given the problems and uncertainties there “may be some opportunity to abate carbon pollution through soil carbon initiatives in the future, but it is grossly irresponsible to make it the centrepiece of a nationwide carbon pollution policy.”

Hunt dismissed those concerns, quoting the CSIRO but when he was pressed on whether he was talking about just soil carbon he said he meant the full range of green carbon initiatives – mallee and mulga revegetation, reforestation, avoided deforestation, soil carbon.

A recent article in Nature (paywalled) came to the conclusion that:

considering carbon storage on land as a means to ‘offset’ CO2 emissions from burning fossil fuels (an idea with wide currency) is scientifically flawed. The capacity of terrestrial ecosystems to store carbon is finite and the current sequestration potential primarily reflects depletion due to past land use. Avoiding emissions from land carbon stocks and refilling depleted stocks reduces atmospheric CO2 concentration, but the maximum amount of this reduction is equivalent to only a small fraction of potential fossil fuel emissions.

?????????????????????????This week I’ve concentrated on the practical side of Climate change – mitigation and adaptation and the relevant policies.

1. China to cap emissions

According to Giles Parkinson news reports from China indicate that the powerful National Development and Reform Commission (NDRC) has proposed a cap on emissions from 2016, from RenewEconomy, picked up at Clean Technica.

What’s more it looks as though China will cease to be an importer of coal within a few years (please note Gina, Clive et al).

Please note also, Tony Abbott and Greg Hunt. The coalition will be phasing out the carbon price just as China is phasing it in. The LNP reckoned a price on carbon was unnecessary because the rest of the world was not going there, remember?

[Update: indigo @ 8 advises that this story is based on a passing comment from a delegate of the NDRC and that no proposal has yet gone forward.]

2. Carbon markets have to take Abbott seriously!

Two weeks ago Giles Parkinson attended a day hosted by the Carbon Market Institute looking at the future of carbon markets in Australia. It seems that the audience of bankers and such had never taken the Direct Action thing seriously, they thought was just a bit of politicking. Now they are having to face the fact that Greg Hunt, former champion debater, will almost certainly be tasked to implement whatever it turns out to be.

Antony Green’s session was the best attended. The only serious question to be resolved on September 15 is whether the LNP can get the numbers in the Senate. The final numbers, Green explained, can be a lottery, with the balance of power possibly finally held by fringe candidates no-one has heard of. Still markets have to deal with the possibilities and this is how they sit:

The forward curve of the carbon market – such as it is – is pricing odds of 60 per cent that the carbon price will no longer exist by July next year, analysts say. The market odds for it to be gone by 2016 are 80 per cent.

The forward curve for contracts in the National Electricity Market is pricing the odds around the same level. Even Bloomberg New Energy Finance, which said earlier this year that there was just a 30 per cent chance of repeal, is now reviewing that assessment and is likely to lift the odds to above 50 per cent.

And yes, there is an issue of compensation, which doesn’t figure so far in LNP budgeting.

3. No more money for adaptation research

I was intrigued to find a blogger from Knoxville, Tennessee listing five policy briefs released by Australia’s National Climate Change Adaptation Research Facility (NCCARF), with seven more to come by June 30 this year. On closer investigation, I found this speech by Yvette D’Ath officially launching their research portfolio, a portfolio of more than 140 peer-reviewed research projects across 33 universities around Australia. D’Ath praised the work of the scientists and appealed to them for help in countering climate denialism.

Ironic really as the NCCARF is to be wound up by the end of June as there was no more money coming from the Government. More than 100 researchers will be affected nationally.

Instead NCCARF2 will be funded at $3 million per annum for two years as a dissemination project.

The same Knoxville blogger notes the release of the EU Strategy on Climate Change Adaptation which was produced by the Directorate-General for Climate Action, which is a program, not a project, of the European Commission. Their 2013 program of work is worth €20.75 million and the employ 160 people internally and externally.

4. Quick charging buses come to Geneva

European technology giant ABB has developed a new technology that will help power the world’s first high-capacity flash charging electric bus system, where buses will receive top up charges in 15 seconds at selected bus stops. A pilot project termed TOSA (Trolleybus Optimisation Système Alimentation) is planned in conjunction with Geneva’s public transport company.

An arm connects with an electricity outlet in the roof of the bus shelter. At the end of the run three to four minutes gives a complete charge. It’s like a trolley bus without overhead wires.

I’m wondering how electric vehicles go with heart pacemakers. I’ve just learned that you can’t use electric hand tools with a pacemaker.

This link has a video showing roughly how the bus shelter connection is made.

5. ‘Black Carbon’ flows from soil to oceans

It was thought that ‘black carbon’ created by the burning of organic matter such as grass or forests stayed in the soil for millions of years.

By examining carbon in rivers it is now thought that up to 40% of such black carbon dissolves and flows into the oceans.

6. Soil carbon farming

I gather that soil carbon farming is a different issue, but seems similarly fraught. Di Martin investigated the soil carbon conundrum.

The shorter story is that some exceptional farmers have demonstrated that soil carbon can be increased dramatically. One farmer did this by ‘pasture cropping’. Native grasses were encouraged and the crop was sown directly into the pasture, rather than plowing, harrowing etc.

Another used ‘cell grazing’, which involves high intensity and high rotation grazing, with long rest periods for pasture.

There are problems in measurement, which may be resolvable with new technology. What is not resolvable, however, is the 100-year guarantee required by international protocols if the activity is deemed to benefit the planet.

Bernard Keane, following Lenore Taylor, was rather scathing about Direct Action soil magic.

7. Renewable energy in the wars

The fossil fuel incumbents are rolling out a campaign to damage the solar industry. One nasty trick being considered in Queensland is the following:

Gross metering – a proposal made in Queensland which would force households to sell all the output from their rooftop systems to the grid operators, and buy it back at a higher price

Campbell Newman keeps saying that feed-in tariffs PV solar are “just ridiculous”.

The campaign seems to be extending to the whole Coalition policy on renewables, if there is one.

There is increasing concern in the [renewables] industry that the Opposition will pave way for the Renewable Energy Target to be diluted, under pressure from state governments, utilities and generators worried about sliding profits from their coal and gas generators, and noisy anti-renewable lobbies promoted by the likes of [Alan] Jones.

Please note the note at the end of the piece:

it seems the biggest problem the [coal] industry faces is a lack of demand. We’ve noted this before, but this week, this was reinforced by reports from China that imported coal is sitting unwanted and clogging up the country’s biggest ports.

Deutsche Bank energy analysts said this was due to “weak coal demand all over China” which had been apparent since late last year. Indeed, half the coal companies in one region of Mongolia had ceased production of thermal coal because of falling prices, and most small coal mines in Shanxi Province had also closed, Deutsche Bank reported.
