The Burning Question debunks peak fossil fuels

I recently met a certain Green Party councillor of a nearby local council who said he thought New Zealand's greenhouse gas emissions would decline by 10 percent in the next twelve months. The decline would be caused partly by restrictions on the availability of oil and gas and partly by the recent decline in the global whole milk powder prices.

I proposed a bet of one thousand dollars (to be given to a climate change project) that there would be no decline in either net or gross greenhouse gas emissions from 2015 to 2016, let alone a decline of 10 percent. In other words I was happy to bet against 'peak oil'. Because don't see how any one can claim to understand anthropogenic climate change as an issue and still hold the view that declining supply of liquid fossil fuels will damage the world's economies.

So I am very pleased to find this talk by Duncan Clark given at University College London on 2 July 2013 about the book The Burning Question co-authored with Mike Berners-Lee.

Their simple thesis is that the available proven reserves of oil gas and coal, that are already recognised as assets on the balance sheets of fossil-fuel companies, exceed a 'likely' carbon budget consistent with limiting average global warming to two degrees Celsius by 2100. And therefore the policy question is "how do we keep trillions of dollars of fossil fuels in the ground?"

The Guardian has a good review of The Burning Question.

Labour's climate change and energy policies - labelling oil and gas developments as 'transitional' does not make them carbon neutral

The New Zealand Labour Party announced their climate change policy on 24 August; the Sunday before last Sunday.

At first glance, it sounds refreshingly like a policy that takes anthropogenic global warming seriously.

A Labour Government will put in place a comprehensive climate change strategy focusing on both mitigation and adaptation, establish an independent Climate Commission and implement carbon budgeting, says Labour Climate Change spokesperson Moana Mackey.
"This is about future-proofing our economy. Making the transition to a low-carbon clean technology economy is not a 'nice to have' as the current Government would have us believe. It is a transition we must make and the sooner we begin, the easier that transition will be."

How did the media respond? Well they ignored it. I haven't seen any reporting of Labour's climate change policy in the Herald, or Stuff/Fairfax, or Radio NZ or TV1 or TV3. I only stumbled onto it via Scoop a week after the release.

Like the 2011 election, the issue of climate change has been notable for it's absense (the snake swallowing the elephant in the room).

However, some of climate change focused NGOs responded positively to Labour's policy. Simon Terry at the Sustainability Council said a carbon budget was the single most important reform. Generation Zero and the Iwi Leaders Group and forest owners welcomed the policy. The mainstream media of course also ignored these NGO views.

However, before I get into the detail of Labour's climate change policy (a topic for another post), it's important to ask "are the dots connected with Labour's energy policy?" Unfortunately, the dots are not connected and the energy policy is 180 degrees contrary to the concept of a carbon budget.

Let's look first at the sixth paragraph of Labour's energy policy.

"It is internationally agreed that the average global temperature increase must be kept below 2 degrees Celsius if the worst effects of climate change are to be avoided. That means two-thirds of currently identified fossil fuel reserves cannot be consumed before 2050, in the absence of widely-deployed (and still unproven) carbon capture and storage technology."

This is fantastic, isn't it? Labour get it! They have read up on the Meinhausen et al Two Degrees Nature paper, the Carbon Tracker Unburnable Carbon Report, Bill McKibbin's Do the Math and the IPCC's Sixth Assessment Report.

They understand that the carbon in existing fossil fuel reserves will when consumed produce significantly more carbon dioxide than the quantity compatible with keeping average global warming to two degrees.

If only that were so. The next sentence tells us that Labour don't get climate change.

"This does not mean that New Zealand should stop developing its own petroleum resources in a world still heavily dependent on oil. But this will be in the context of transitioning to renewable energy, which New Zealand and the rest of the world needs rapidly to do."

This is inconsistent and nonsense. This is pure spin. Someone else somewhere else must keep their fossil fuel reserves in the ground to avoid dangerous climate change. But not New Zealand. Under a Labour-led government, the private sector will develop New Zealand's oil and gas reserves and invest in oil and gas infrastructure, with say a 40 or 50 year life span, over which they will expect to get a market return. Thats most of the years until 2100. The very time frame that the IPCC low emissions pathways say we need to reduce greenhouse gas emissions by 70%.

What is Labour thinking here? Where does Labour think the carbon dioxide from NZ's new hydrocarbon reserves will end up? Is Labour saying that only the world hydrocarbon reserves contain carbon and New Zealand's hydrocarbon reserves don't? Or maybe if you label the NZ hydrocarbons as "transition" fuels there are fewer carbon atoms? Again this is nonsense.

I can only guess that Labour, in stating that their policy is in "the context of transitioning to renewable energy", are arguing that oil and gas are now "transition fuels" to renewable energy supplies. Again this is nonsense. Are Labour now agreeing with Nick Smith?

I am not the only person to note the inherent contradiction in Labour's policy. Bryan Walker has already noted that the intellectual hollowness is plain in Labour's policy. Walker said;

"Political parties and governments which support expanded exploration and development of fossil resources either do not understand the severity of the scientific message or are so consumed by the prospects of economic wealth that they are determined not to heed it."

Ditto Forest and Bird's Kevin Hackwell;

"If Labour is taking climate change seriously it would realise that its fossil fuels policy is at odds with the party's overarching policy statements on sustainability and climate change."

Labour really need to be challenged on this. It's as if Labour has set a compass bearing for the destination and then headed off in the exact opposite direction. If there isn't an understanding of the limited carbon budget in both your energy policy and your climate change policy, then it's pretty much a 'fail' before even looking at the detail of the climate change policy.

Nick Smith blows hot gas for more global warming

What has happened to the hon Dr Nick Smith? The former Minister of Climate Change Issues, A while back he resigned from all his ministerial offices when his conflict of interest in the ACC case of his National-insider friend Brownyn Pullar became public.

Well Nick Smith is back and is promoting the extraction of unconventional gas via hydraulic fracturing.

Smith has written an op-ed in the NZ Herald Fracking the sensible choice for NZ.

Fracking technologies are underpinning an energy revolution in the United States. Huge unconventional shale gas resources in Louisiana and Pennsylvania are coming on stream, enabling gas to replace coal-fired electricity generation. Gas emits one-third the greenhouse gas emissions of coal.

So, according to Smith, from a global warming perspective, unconventional gas is implicitly okay as its emits one-third the greenhouse gas emissions of coal.

Smith concludes that NZ needs;

a strong economy and a clean environment. That will only be possible if we take a rational and science-based approach to our natural resources and risk management.

But promoting unconventional gas development is not the climate science based approach.

Thats abundantly clear from James Hansen's speaking tour of New Zealand in 2011. Did Smith miss these?

Kharecha and Hansen, in their 2008 paper Implications of "peak oil" for atmospheric CO2 and climate. Global Biogeochem. Cycles, 22, GB3012, doi:10.1029/2007GB003142, have clearly told us that we can only keep carbon dioxide concentrations from exceeding about 450 ppm by 2100, if emissions from coal, unconventional fossil fuels, and land use are constrained.

The specific issue of whether a transition to conventional natural gas will actually reduce future greenhouse gas emissions is dealt with in Myhrvold and Caldeira (2012) Greenhouse gases, climate change and the transition from coal to low-carbon electricity.

The Carnegie Institute explains Caldeira and Myhrvold's conclusion; Only the lowest CO2 emitting technologies can avoid a hot end-of-century.

..in the case of natural gas—increasingly the power industry’s fuel of choice, because gas reserves have been growing and prices have been falling—the study finds that warming would continue even if over the next 40 years every coal-fired power plant in the world were replaced with a gas-fueled plant.

As Joe Romm says natural gas is a bridge to nowhere
