Chinn and Hart (2021) argue that their experiment on the effects of communicating the scientific consensus on climate change revealed “mixed” and “inconsistent findings”. We note that Chinn and Hart (2021) provide clear and consistent evidence that the scientific consensus message has positive indirect effects on climate beliefs, attitudes, and support for public action, and that these effects are more pronounced among conservatives (as predicted). Importantly, however, the authors’ claim that these positive findings might simply be the result of an experimental design choice: the use of a pre-test of the dependent variables. Here we argue that no convincing evidence is provided for the conclusion that pre-tests should not be used. In fact, contrary to the authors’ recommendation, we make the case that the inclusion of a pre-test in randomized controlled designs increases power and precision. Furthermore, we point to its central importance for the ability to capture and evaluate the Gateway Belief Model’s (GBM) key predictions about changes in public attitudes.

Global Climate Change can affect human life and activities. The rising amount of natural disasters, the warming of the Earth and the melting of the icebergs are some examples of its effects. This study is conducted to analyze the coverage of global climate change issue in four Malaysia mainstream newspapers. The data for this study are collected from January 2008 to December 2010. A content analysis is conducted to identify the frequency of the articles related with global climate change, the articles length, the trend of newspaper coverage and the frames of the articles. The findings for this study will provide an understanding about the ways Malaysia mainstream newspapers provide the coverage about Global Climate Change and the audience reactions towards the issue. The findings also suggested that the coverage of global climate change is influenced by the events pertaining the issue. This can be observed from the trend of newspaper coverage. Finally, the result on the frames indicates that the most published topic in global climate change issue is public action to reduce the effects of global climate change and reduce the emissions of the greenhouse gas.

This paper analyzes data collected but not reported in the study featured in van der Linden, Leiserowitz, Feinberg, and Maibach [van der Linden et al., 2015]. VLFM report finding that a “scientific consensus” message “increased” experiment subjects' “key beliefs about climate change” and “in turn” their “support for public action” to mitigate it. However, VLFM fail to report that message-exposed subjects' “beliefs about climate change” and “support for public action” did not vary significantly, in statistical or practical terms, from those of a message-unexposed control group. The paper also shows how this absence of an experimental effect was obscured by a misspecified structural equation model.

Purpose In recent years, the manifestation of the effects of climate change in coastal zones has prompted governments to mobilize and propose adaptation measures to reduce the vulnerability of their populations. For the governments responsible for the implementation of climate policies, adaptation still represents a novel field of action. The purpose of this paper is to show, via the example of Quebec’s coastal zone, how the transformation of public action relating to adaptation remains difficult. Design/methodology/approach For this case study, a qualitative method which combines documentary analysis and semi-directed interviews was selected. Findings The study shows how adaptation becomes a new issue in public action for the different authorities dealing with the effects of climate change in Quebec’s coastal zone. However, the results show that, as with other public policies, path dependence and incrementalism can be observed and limit the scope of public action and of the transformational processes in the field of adaptation. The technical–scientific approach to risk management is dominant, and the adaptation is not approached in a transversal way, despite its importance. Finally, concrete adaptation initiatives appear to be mostly relegated to the local scale, in an informal decentralization process. Originality/value This study contributes to improve climate action by favouring a reflection on the consideration of the conceptual and theoretical framework in the climate change adaptation literature and offers decision-makers and practitioners keys to the understanding of mechanisms underlying public action in the field of adaptation.

In this paper, we respond to the critiques presented by [Kahan, 2017]. Contrary to claims that the scientific consensus message did not significantly influence the key mediator and outcome variables in our model, we show that the experiment in [van der Linden et al., 2015] did in fact directly influence key beliefs about climate change. We also clarify that the Gateway Belief Model (GBM) is theoretically well-specified, empirically sound, and as hypothesized, the consensus message exerts a significant indirect influence on support for public action through the mediating variables. We support our conclusions with a large-scale replication.

Food security and the sustainability of native ecosystems depends on plant-insect interactions in countless ways. Recently reported rapid and immense declines in insect numbers due to climate change, the use of pesticides and herbicides, the introduction of agricultural monocultures, and the destruction of insect native habitat, are all potential contributors to this grave situation. Some researchers are working towards a future where natural insect pollinators might be replaced with free-flying robotic bees, an ecologically problematic proposal. We argue instead that creating environments that are friendly to bees and exploring the use of other species for pollination and bio-control, particularly in non-European countries, are more ecologically sound approaches. The computer simulation of insect-plant interactions is a far more measured application of technology that may assist in managing, or averting, ‘Insect Armageddon' from both practical and ethical viewpoints.

Abstract We are in a period of relatively rapid climate change. This poses challenges for individual species and threatens the ecosystem services that humanity relies upon. Temperature is a key stressor. In a warming climate, individual organisms may be able to shift their thermal optima through phenotypic plasticity. However, such plasticity is unlikely to be sufficient over the coming centuries. Resilience to warming will also depend on how fast the distribution of traits that define a species can adapt through other methods, in particular through redistribution of the abundance of variants within the population and through genetic evolution. In this paper, we use a simple theoretical ‘trait diffusion’ model to explore how the resilience of a given species to climate change depends on the initial trait diversity (biodiversity), the trait diffusion rate (mutation rate), and the lifetime of the organism. We estimate theoretical dangerous rates of continuous global warming that would exceed the ability of a species to adapt through trait diffusion, and therefore lead to a collapse in the overall productivity of the species. As the rate of adaptation through intraspecies competition and genetic evolution decreases with species lifetime, we find critical rates of change that also depend fundamentally on lifetime. Dangerous rates of warming vary from 1°C per lifetime (at low trait diffusion rate) to 8°C per lifetime (at high trait diffusion rate). We conclude that rapid climate change is liable to favour short-lived organisms (e.g. microbes) rather than longer-lived organisms (e.g. trees).
