The overwhelming majority of the scientific community agrees that climate change (CC) is occurring and is caused by anthropogenic, or human-caused, forcing. The global populace is aware of this phenomenon but appears to be unconcerned about CC and is slow to adopt potential mitigative actions. CC is a unique and complex phenomenon affected by various kinds of uncertainty, rendering communicative efforts particularly challenging. The compound and, potentially, conflicting uncertainties inherent in CC engender public ambivalence about the issue. The treatment of uncertainty in the Intergovernmental Panel on Climate Change’s (IPCC’s) reports have been shown to be confusing to policymakers and the general public, further confounding public outreach efforts. Given diverse communication styles and the multifaceted nature of CC, an assortment of strategies has been recommended to maximize understanding and increase salience. In particular, using evidence-based approaches to communicate about probabilistic outcomes in CC increases communicative efficiency.

<p>While it is now widely accepted by scientists and governments that human activity contributes to climate change, there is a lack of understanding whether this realisation is now gaining greater attraction with the general public than it had 5 or 10 years ago. Additional gaps in knowledge relate to the link between awareness and action, which could be hypothesised to have become stronger in light of evidence being produced of some projected climate changes occurring already. This article examines climate change awareness and the link with travel-related decision-making by adopting an under-utilised origin perspective in Wellington, New Zealand. The findings, generated by a household mail survey, indicate that the majority of the respondents are aware of tourism’s contribution to climate change and think that it is likely that their lives in New Zealand will be negatively affected by climate change. However, when examining the respondents’ recent holiday decision-making, it is evident that for the overwhelming majority, climate change awareness does not appear to influence travel-related decisions. This article concludes by discussing demand-focused measures aimed at reducing the GHG emissions generated by tourism.</p>

Abstract. Humanity's situation with respect to climate change is sometimes compared to that of a frog in a slowly boiling pot of water, meaning that change will happen too gradually for us to appreciate the likelihood of catastrophe and act before it is too late. I argue that the scientific community is not yet telling the boiling frog what he needs to know. I use a review of the figures included in two reports of the Intergovernmental Panel on Climate Change to show that much of the climate science communicated to policymakers is presented in the form of projections of what is most likely to occur, as a function of time (equivalent to the following statement: in 5 min time, the water you are sitting in will be 2 ∘C warmer). I argue from first principles that a more appropriate means of assessing and communicating the risks of climate change would be to produce assessments of the likelihood of crossing non-arbitrary thresholds of impact, as a function of time (equivalent to the following statement: the probability of you being boiled to death will be 1 % in 5 min time, rising to 100 % in 20 min time if you do not jump out of the pot). This would be consistent with approaches to risk assessment in fields such as insurance, engineering, and health and safety. Importantly, it would ensure that decision makers are informed of the biggest risks and hence of the strongest reasons to act. I suggest ways in which the science community could contribute to promoting this approach, taking into account its inherent need for cross-disciplinary research and for engagement with decision makers before the research is conducted instead of afterwards.

AbstractIn recent years, the Intergovernmental Panel on Climate Change (IPCC) has been collaborating with Indian institutions to organise outreach events. This essay draws on the perspective of participants, speakers and organisers of 17 in-person outreach events conducted across India in 2018 and 2020, to share insights and recommendations for future IPCC events in India and other developing country contexts. The formats analysed in this essay range from panel events with very large public audiences to more focused workshops, meetings and seminars. Target audiences covered both academic and non-academic audiences and included researchers, teachers, students, industry and NGOs. The events, while achieving their main objective of communicating the findings of IPCC reports, also provided a platform for open discussion of localised climate impacts and good practices in adaptation and mitigation. There are, however, notable challenges to public outreach in India, specifically in terms of attracting an adequate number of participants, experts’ availability, communicating to a diverse audience and translation into local languages. The biggest challenge faced by speakers was a lack of knowledge about the number of attendees and the composition of the audience prior to an event. It is our recommendation that future outreach events in India are designed to be interactive, tailored to the regional context and complemented by simplified communication materials. Speakers should be provided with audience information and background prior to the event, and greater reach into rural areas, including school children, could be achieved with material in local languages. Additionally, event organisers often require logistical and operational support to host outreach events.

Abstract The rapid changes in global average surface temperature have unfathomed influences on human society, environment, ecosystem, availability of food and fresh water. Multiple lines of evidence indicate that warming of the climate system is unequivocal, and human-induced effects are playing an enhanced role in climate change. It is of utmost importance to ascertain the hydroclimatological changes in order to ascertain the characteristics of detection and attribution (D&A) of human-induced anthropogenic influences on recent warming. Climate change D&A are interrelated. Their study enhances our understanding about the rudimentary causes leading to climate changes and hence, considered as a decisive element in all Intergovernmental Panel on Climate Change Assessment Reports. An extensive discussion of the concerned scientific literature on climate change D&A is indispensably needed for the scientific community to assess climate change threats in clear terms. This study has reviewed various processes and advances in climate change D&A analyses at global/regional scales during the past few decades. Regression-based optimal fingerprint approach is majorly employed in climate change D&A studies. The accumulation of inferences presented in this study from numerous studies could be extremely helpful for the scientific community and policymakers as they deal with climate change adaptation and mitigation challenges.

Current debates about climate change or vaccine safety provide an alarming illustration of the potential impacts of dissent about scientific claims. False beliefs about evidence and the conclusions that can be drawn from it are commonplace, as is corrosive doubt about the existence of widespread scientific consensus. Deployed aggressively and to political ends, ill-founded dissent can intimidate scientists, stymie research, and lead both the public and policymakers to oppose important policies firmly rooted in science. To criticize dissent is, however, a fraught exercise. Skepticism and fearless debate are key to the scientific process, making it both vital and incredibly difficult to characterize and identify dissent that is problematic in its approach and consequences. Indeed, as de Melo-Martín and Intemann show, the criteria commonly proposed as means of identifying inappropriate dissent are flawed, and the strategies generally recommended to tackle such dissent are not only ineffective but could even make the situation worse. The Fight against Doubt proposes that progress on this front can best be achieved by enhancing the trustworthiness of the scientific community and being more realistic about the limits of science when it comes to policymaking. It shows that a richer understanding is needed of the context in which science operates so as to disarm problematic dissent and those who deploy it in the pursuit of their goals.

AbstractConstraints and limits to adaptation are critical to understanding the extent to which human and natural systems can successfully adapt to climate change. We conduct a systematic review of 1,682 academic studies on human adaptation responses to identify patterns in constraints and limits to adaptation for different regions, sectors, hazards, adaptation response types, and actors. Using definitions of constraints and limits provided by the Intergovernmental Panel on Climate Change (IPCC), we find that most literature identifies constraints to adaptation but that there is limited literature focused on limits to adaptation. Central and South America and Small Islands generally report greater constraints and both hard and soft limits to adaptation. Technological, infrastructural, and ecosystem-based adaptation suggest more evidence of constraints and hard limits than other types of responses. Individuals and households face economic and socio-cultural constraints which also inhibit behavioral adaptation responses and may lead to limits. Finance, governance, institutional, and policy constraints are most prevalent globally. These findings provide early signposts for boundaries of human adaptation and are of high relevance for guiding proactive adaptation financing and governance from local to global scales.

International climate negotiations occur against the backdrop of increasing collective risk: the likelihood of catastrophic economic loss due to climate change will continue to increase unless and until global mitigation efforts are sufficient to prevent it. We introduce a novel alternating-offers bargaining model that incorporates this characteristic feature of climate change. We test the model using an incentivized experiment. We manipulate two important distributional equity principles: capacity to pay for mitigation of climate change and vulnerability to its potentially catastrophic effects. Our results show that less vulnerable parties do not exploit the greater vulnerability of their bargaining partners. They are, rather, more generous. Conversely, parties with greater capacity are less generous in their offers. Both collective risk itself and its importance in light of the recent Intergovernmental Panel on Climate Change report make it all the more urgent to better understand this crucial strategic feature of climate change bargaining.

AbstractEcosystem-based disaster risk reduction (Eco-DRR) is an important concept to the adaption of climate change for a sustainable life. In Japan, it is anticipated that damages caused by sediment production will be increased as the intensity and amount of rainfall are increased by climate change. Thus, we need to know the Eco-DRR effect of the forest for planning sustainable land use by evidence-based data. In this study, we focused on the relationship between sediment production rate and the understory coverage rate of a low mountain forest in the granite area. From the results of the field survey and statistical meta-analysis, the sediment production rate was reduced by 97% in granite area mountain forest when the understory coverage rate was 60% or more compared to when less than 30% by evidence-based data. Accordingly, we found that it will be necessary to keep forests with an understory coverage rate of 60% or more when considering the risk-reducing effect of sediment disaster in granite area mountain forests for the adaption of climate change.
