The regional governance of climate adaptation: A framework for developing legitimate, effective, and resilient governance arrangements

Adaptation to climate change raises important governance issues. Notwithstanding the increasing attention on climate adaptation at the global and European level, the variety of local conditions and climate impacts points towards a prime role for regional actors in climate change adaptation. They face the challenge of developing and implementing adaptation options and increasing the adaptive capacity of regions so that expected or unexpected impacts of future climate change can be addressed. This paper presents a conceptual framework to analyse the regional governance of climate adaptation. It addresses the following key questions: (1) What are the distinct challenges for the regional governance of climate adaptation? (2) Which concepts can guide the design of new governance arrangements and strategies? (3) What challenges to legal principles are posed by the climate? (4) What research methods are suitable for developing and testing governance arrangements and strategies? We present a framework designed to address each of these questions; it has analytical, design, normative, and methodological components. In the paper, examples from the Dutch regional governance of climate adaptation serve as illustrations of the conceptual argumentation.

Going beyond two degrees? The risks and opportunities of alternative options

Since the mid-1990s, the aim of keeping climate change within 2 °C has become firmly entrenched in policy discourses. In the past few years, the likelihood of achieving it has been increasingly called into question. The debate around what to do with a target that seems less and less achievable is, however, only just beginning. As the UN commences a two-year review of the 2 °C target, this article moves beyond the somewhat binary debates about whether or not it should or will be met, in order to analyse more fully some of the alternative options that have been identified but not fully explored in the existing literature. For the first time, uncertainties, risks, and opportunities associated with four such options are identified and synthesized from the literature. The analysis finds that the significant risks and uncertainties associated with some options may encourage decision makers to recommit to the 2 °C target as the least unattractive course of action.

Mainstreaming Climate Policy: The Case of Climate Adaptation and the Implementation of EU Water Policy

Despite the fact that mainstreaming of climate change into existing EU sectoral policies is a key aim, empirical knowledge of how it works in practice remains scarce. With this paper we explore the degree to which climate considerations are taken into account in the implementation of one of the most influential pieces of European water legislation, the Water Framework Directive and, more importantly, we assess possible explanations for the geographical variability in levels of mainstreaming observed. Our empirical research is based on an analysis of both EU and local policy documents, as well as more than forty in-depth interviews, and shows that, for various reasons, the degree of mainstreaming that has taken place differs widely. We conclude that timely incentives and clear guidance will be necessary to ensure progress is made by all, but that a residual fear that the adaptation agenda is open to abuse by those seeking to rationalise failures to fully implement the Water Framework Directive has put a brake on the mainstreaming agenda.

Understanding the Paradoxes of Multilevel Governing: Climate Change Policy in the European Union

The European Union (EU) has sought to lead the world in the adoption of ambitious climate change mitigation targets and policies. In an attempt to characterize and broadly explain the resulting pattern of EU climate governance, scholars have employed the term “multi-level reinforcement.” This term does help to account for the paradoxical situation whereby the EU seeks to lead by example but is itself a relatively leaderless system of governance. Drawing on a much fuller empirical account of the evolution of EU climate governance, this article finds that the term captures some but not all aspects of the EUs approach. It identifies four other paradoxical features of the EUs approach and assesses the extent to which they exhibit “multi-level reinforcement.” It concludes by looking forward and examining the extent to which all five features are expected to enable and/or constrain the EUs ability to maintain a leading position in climate governance.

‘When knowledge matters’: the role and influence of the Royal Commission on Environmental Pollution

Adopting a ‘knowledge perspective’, in which policy-making is seen as a process of collective learning through argument and persuasion, this paper assesses the record of the UK Royal Commission on Environmental Pollution as an advocate of concepts and reforms associated with ecological modernization. Drawing on extensive empirical research, it considers how the social and political climate in which the Commission has operated, as well as certain characteristics of the Commission as an advisory body, have conditioned its degree of influence over time. It argues that in various roles—as knowledge broker, policy entrepreneur and persuasive advocate—the Commission has been able to exert a significant influence on environmental policy in the UK and beyond. The paper also reflects on the utility of different approaches in theorizing the role of advisory bodies in the policy process. Copyright

Magnetic field-cycling NMR and 14N, 17O quadrupole resonance in the explosive pentaerythritol tetranitrate (PETN)☆

The explosive pentaerythritol tetranitrate (PETN) C(CH(2)-O-NO(2))(4) has been studied by (1)H NMR and (14)N NQR. The (14)N NQR frequency and spin-lattice relaxation time T(1Q) for the nu(+) line have been measured at temperatures from 255 to 325K. The (1)H NMR spin-lattice relaxation time T(1) has been measured at frequencies from 1.8kHz to 40MHz and at temperatures from 250 to 390K. The observed variations are interpreted as due to hindered rotation of the NO(2) group about the bond to the oxygen atom of the CH(2)-O group, which produces a transient change in the dipolar coupling of the CH(2) protons, generating a step in the (1)H T(1) at frequencies between 2 and 100kHz. The same mechanism could also explain the two minima observed in the temperature variation of the (14)N NQR T(1Q) near 284 and 316K, due in this case to the transient change in the (14)N...(1)H dipolar interaction, the first attributed to hindered rotation of the NO(2) group and the second to an increase in torsional amplitude of the NO(2) group due to molecular distortion of the flexible CH(2)-O-NO(2) chain which produces a 15% increase in the oscillational amplitude of the CH(2) group. The correlation times governing the (1)H T(1) values are approximately 25 times longer than those governing the (14)N NQR T(1Q), explained by the slow spin-lattice cross-coupling between the two spin systems. At higher frequencies, the (1)H T(1) dispersion results show well-resolved dips between 200 and 904kHz assigned to level crossing with (14)N and weaker features between 3 and 5MHz tentatively assigned to level crossing with (17)O.

Climate policy innovation: developing an evaluation perspective

A key dimension of the debate about policy innovation is the extent to which new policies achieve significant and lasting effects on the problems they purport to address. However, little is known about such effects. We break new ground by investigating how far current evaluation practices in a policy system with relatively ambitious climate policies – the European Union – identify the most effective (carbon-reducing) policies. We find that a small number of policy instruments are projected to deliver the lion’s share of emission reductions. Setting aside the special case of emissions trading, these instruments are not particularly innovative. If significant practical and political obstacles can be addressed, more (detailed) evaluations could enhance the evidence base and also the political prospects for delivering deeper emissions cuts through to 2050. An evaluation perspective could also offer a very different way to consider policy innovation dynamics.

AHT-ChIP-seq: a completely automated robotic protocol for high-throughput chromatin immunoprecipitation.

ChIP-seq is an established manually-performed method for identifying DNA-protein interactions genome-wide. Here, we describe a protocol for automated high-throughput (AHT) ChIP-seq. To demonstrate the quality of data obtained using AHT-ChIP-seq, we applied it to five proteins in mouse livers using a single 96-well plate, demonstrating an extremely high degree of qualitative and quantitative reproducibility among biological and technical replicates. We estimated the optimum and minimum recommended cell numbers required to perform AHT-ChIP-seq by running an additional plate using HepG2 and MCF7 cells. With this protocol, commercially available robotics can perform four hundred experiments in five days.

14N quadrupole resonance and 1H T1 dispersion in the explosive RDX

The explosive hexahydro-1,3,5-trinitro-s-triazine (CH2-N-NO2)3, commonly known as RDX, has been studied by 14N NQR and 1H NMR. NQR frequencies and relaxation times for the three ν+ and ν- lines of the ring 14N nuclei have been measured over the temperature range 230-330 K. The 1H NMR T1 dispersion has been measured for magnetic fields corresponding to the 1H NMR frequency range of 0-5.4 M Hz. The results have been interpreted as due to hindered rotation of the NO2 group about the N-NO2 bond with an activation energy close to 92 kJ mol(-1). Three dips in the 1H NMR dispersion near 120, 390 and 510 kHz are assigned to the ν0, ν- and ν+ transitions of the 14NO2 group. The temperature dependence of the inverse line-width parameters T2∗ of the three ν+ and ν- ring nitrogen transitions between 230 and 320 K can be explained by a distribution in the torsional oscillational amplitudes of the NO2 group about the N-NO2 bond at crystal defects whose values are consistent with the latter being mainly edge dislocations or impurities in the samples studied. Above 310 K, the 14N line widths are dominated by the rapid decrease in the spin-spin relaxation time T2 due to hindered rotation of the NO2 group. A consequence of this is that above this temperature, the 1H T1 values at the quadrupole dips are dominated by the spin mixing time between the 1H Zeeman levels and the combined 1H and 14N spin-spin levels.

Experimental and theoretical studies of the 14N quadrupole tensors in 1H-1,2,3-benzotriazole

Abstract The 14N quadrupole tensor elements have been determined for the title compound by a combination of double resonance level crossing, and quadrupole dip spectroscopy. Three of the four sites in the lattice were assigned. Analysis of the spectra was assisted by consideration of 1,2,3-triazole-4,5-dicarboxylic acid, which from its spectra appears to be in the 1H-form. Combination of these results with ab initio studies of (a) the equilibrium geometry of the monomeric 1H- and 2H-tautomers and (b) cluster studies at the 1H-benzotriazole positions, allowed a firm assignment of the quadrupole parameters at the three main chemical sites, although the different lattice positions in the asymmetric unit could not be identified by these means.
