An iconic approach for representing climate change

International and national greenhouse gas emissions reduction goals implicitly rely in part on individuals undertaking voluntary emissions reductions through lifestyle decisions. Whilst there is widespread public recognition of climate change as an issue, there are many barriers – cognitive, psychological and social – preventing individuals from enacting lifestyle decarbonisation. More effective climate change communication approaches are needed which allow individuals to engage meaningfully with climate change, thus opening new prospects for lifestyle decarbonisation. This study presents an iconic approach to engagement, tested in the UK context, which allows individuals to approach climate change through their own personal values and experiences. The iconic approach harnesses the emotive and visual power of climate icons with a rigorous scientific analysis of climate impacts under a different climate future. Although some climate icons already exist – for example the Thermohaline Circulation shutdown – these ‘expert-led’ icons fail to effectively engage ‘non-experts’. We demonstrate that the non-expert-led iconic approach helps overcome some of the cognitive and affective barriers that impede action towards lifestyle decarbonisation.     

Personalized risk messaging can reduce climate concerns

One potential barrier to climate policy action is that individuals view climate change as a problem for people in other parts of the world or for future generations. As some scholars argue, risk messaging strategies that make climate change personally relevant may help overcome this barrier. In this article, we report a large-n survey experiment on San Francisco Bay Area residents to investigate how providing spatially-resolved risk information to individuals shapes their climate risk perceptions in the context of sea-level rise. Our results suggest that personalized risk messaging can sometimes reduce concern about sea-level rise. These experimental effects are limited to respondents who believe that climate change is happening. Further, we do not find an effect of providing local risk messages on an individual's willingness to pay for regional climate adaptation measures. Our results emphasize that local messaging strategies around sea-level rise risks may not have the clear impacts that some advocates and scholars presume.

Communicating uncertainty: lessons learned and suggestions for climate change assessment

Assessments of climate change face the task of making information about uncertainty accessible and useful to decision-makers. The literature in behavior economics provides many examples of how people make decisions under conditions of uncertainty relying on inappropriate heuristics, leading to inconsistent and counterproductive choices. Modern risk communication practices recommend a number of methods to overcome these hurdles, which have been recommended for the Intergovernmental Panel on Climate Change (IPCC) assessment reports. This paper evaluates the success of the most recent IPCC approach to uncertainty communication, based on a controlled survey of climate change experts. Evaluating the results from the survey, and from a similar survey recently conducted among university students, the paper suggests that the most recent IPCC approach leaves open the possibility for biased and inconsistent responses to the information. The paper concludes by suggesting ways to improve the approach for future IPCC assessment reports. To cite this article: A. Patt, S. Dessai, C. R. Geoscience 337 (2005).     

南京市居民网络购物行为特征——以书籍和衣服为例

随着信息通讯技术(ICT)的飞速发展,网络购物日益成为当今社会经济生活的重要组成部分,深刻影响了居民的购物消费行为和传统零售业的发展。不同国家、不同人群、不同商品类型的居民购物行为具有一定差异。本文在问卷调查的基础上,分析南京市居民网络购物行为特征,并区分不同商品类型的居民网购行为特征差异,对理解网络购物和实体购物相互作用关系及网购对于交通出行和城市零售业空间的影响具有重要意义。结果表明：居民网络购物行为是一个复杂的过程,不同类型商品、不同频率网购人群在社会经济属性、空间特征、网络使用及购物习惯、购物态度上有明显差异,其中不同频率网购衣服的人群在特征上的差异更为显著,体验型商品对网络购物这一新型购物方式的响应更为强烈。     

贵州省气象甚高频通信网最佳方案的研究

通过时在贵州山区组建甚高频通信网进行工程设计、方案试验、运行调整，确立了该通信网的最佳方案。所谓最佳方案，即要求该网的复盖率为１００％，中转环节最少、信号稳定可靠，既能进行话传，又能进行数传。目前，在山区组建这样的甚高频通信网及其实现的方法，在我国尚属先例。
