The paper is devoted to the development of international legal regulation in the field of combating climate change. Over the years, states, in the face of scientific uncertainty, have been trying to find ways to keep global warming at 1.5 °C by establishing international commitments of various configurations.When cooperating in the fight against climate change, additional substantive discussions arise, related, for example, to the implementation of international trade measures or the provision of human rights. However, the main direction remains the one covered by the context of sustainable development, ESG principles for business, government and society, strategies for energy policies of states, cooperation in adaptation and assistance to developing countries.Approaches to the international legal regulation of cooperation in the field of combating climate change began to form when the international community started to pay much attention to the international legal protection of atmospheric air and the protection of the ozone layer. As early as the preamble to the 1987 Montreal Protocol, the emphasis was placed on the potential climate impact of ozone-depleting substance emissions.The international legal regime established by the 1992 UN Framework Convention on Climate Change, in fact, outlined guidelines for finding optimal forms of cooperation, taking into account changes not only in the state of the environment, but also in the economic agenda. The Conference of the Parties has been identified as the key institutional platform for cooperation. Currently in conjunction with the 1992 Framework Convention and the 2015 Paris Climate Agreement the Conference of the Parties provides the conditions for their implementation.

The aim of this study was to investigate the attitudes of Grade 6 students and their science teachers towards a socio-constructivist way of learning and teaching science, compared to the usual way of learning and teaching science; as well as the science teaching practices. The data was collected during a period of eight weeks in two rural primary schools in the Limpopo Province, South Africa. A five-week intervention was conducted during which the researchers taught science in a socio-constructivist way. Observations were conducted as well as interviews with the teachers and 10 students (5 in each school) using the CLES observation guide, CLES interview guide, CLES Actual questionnaire and CLES Preferred questionnaire. The interviewed students also participated in a focus group. The results showed that some elements of socio-constructivism were appreciated by the students and teachers and other elements not. The students’ attitudes were positive about scientific uncertainty and student negotiation and rather negative about critical voice and shared control. The attitudes of the teachers were more ambiguous.

Abstract Background The COVID-19 pandemic brought the production of scientific knowledge onto the public agenda in real-time. News media and commentators analysed the successes and failures of the pandemic response in real-time, bringing the process of scientific inquiry, which is also fraught with uncertainty, onto the public agenda. We examine how Canadian newspapers framed scientific uncertainty in their initial coverage of the COVID-19 pandemic and how journalists made sense of the scientific process. Methods We conducted a framing analysis of 1143 news stories and opinion during the first two waves of the COVID-19 pandemic. Using a qualitative analysis software, our analysis focused, first, on how scientific uncertainty was framed in hard news and opinion discourse (editorial, op-ed). Second, we compared how specialist health and science reporters discussed scientific evidence versus non-specialist reporters in hard news and columns. Results Uncertainty emerged as a “master frame” across the sample, and four additional framing strategies were used by reporters and commentators when covering the pandemic: (1), evidence -focusing on presence or absence of it-; (2) transparency and leadership -focusing on the pandemic response-; (3) duelling experts – highlighting disagreement among experts or criticizing public health decisions for not adhering to expert recommendations-; and (4) mixed messaging -criticizing public health communication efforts. While specialist journalists understood that scientific knowledge evolves and the process is fraught with uncertainty, non-specialist reporters and commentators expressed frustration over changing public health guidelines, leading to the politicization of the pandemic response and condemnation of elected officials’ decisions. Conclusions Managing scientific uncertainty in evolving science-policy situations requires timely and clear communication. Public health officials and political leaders need to provide clear and consistent messages and access to data regarding infection prevention guidelines. Public health officials should quickly engage in communication course corrections if original messages are missing the intended mark, and clearly explain the shift. Finally, public health communicators should be aware of and more responsive to a variety of media reporters, who will bring different interpretative frames to their reporting. More care and effort are needed in these communication engagements to minimize inconsistencies, uncertainty, and politicization.

The population of humpback whales (Megaptera novaeangliae) wintering off eastern South America was exploited by commercial whaling almost to the point of extinction in the mid-twentieth century. Since cessation of whaling in the 1970s it is recovering, but the timing and level of recovery is uncertain. We implemented a Bayesian population dynamics model describing the population’s trajectory from 1901 and projecting it to 2040 to revise a previous population status assessment that used Sampling-Importance-Resampling in a Bayesian framework. Using our alternative method for model fitting (Markov chain Monte Carlo), which is more widely accessible to ecologists, we replicate a “base case scenario” to verify the effect on model results, and introduce additional data to update the status assessment. Our approach allowed us to widen the previous informative prior on carrying capacity to better reflect scientific uncertainty around historical population levels. The updated model provided more precise estimates for population sizes over the period considered (1901–2040) and suggests that carrying capacity (K: median 22,882, mean 22,948, 95% credible interval [CI] 22,711–23,545) and minimum population size (N1958: median 305, mean 319, 95% CI 271–444) might be lower than previously estimated (K: median 24,558, mean 25,110, 95% CI 22,791–31,118; N1958: median 503, mean 850, 95% CI 159–3,943). However, posterior 95% credible intervals of parameters in the updated model overlap those of the previous study. Our approach provides an accessible framework for investigating the status of depleted animal populations for which information is available on historical mortality (e.g., catches) and intermittent estimates of population size and/or trend.

The persisting gap between the scientific knowledge of the effects of radiation and the public perception of radiation risk remains a source of potential problems not only in connection with probable radiation accidents, but also in the implementation of new long-term solutions, such as siting of radioactive waste disposal facilities, the nuclear-fuel cycle (NFC) closure and others. The authors analyze why, in the 30 years after the Chernobyl accident, nuclear industry specialists and radiological community failed to change this situation substantially and reflect on what one can do in the future. The authors attribute the low efficiency of the traditional approach “explaining risk in simple language", on the one hand, to the known limitations of scientific and technical rationalism in matters relating to human health, and, on the other hand, to internal inconsistency of modern approaches to regulating radiation risks in the range of fundamental scientific uncertainty. The authors present two directions to move forward. The first one is to involve social science specialists, who study the patterns of public perception of health risks (risk communication experts), in a dialogue with the public. The second one is the recognition by the professional radiological community of their moral responsibility for “side” social effects arising from the insufficient social adaptation of risk management recommendations offered to the authorities, with the subsequent transition to a value-oriented risk communication strategy.

Abstract In the nascent deep-sea mining industry, there is currently a high degree of uncertainty about what impacts prolonged metal extraction will have on the receiving environment. There is also concern regarding the transparency and monitoring of operations since the target environment is extremely remote and inaccessible. Polymetallic nodule collection is being pursued, which is distinct from other forms of deep-sea mining in that the resource is distributed in a thin layer atop the seabed, unlike cobalt-rich crusts or massive sulfides, which are concentrated in specific areas. The second distribution of nodules provides opportunities for dynamic mine planning not available for other mineral sources as many constraints normally affecting mining operations like waste stripping or underground development are absent. Also, the highly mobile ship-based collection system that utilizes robotic collectors is easily relocated to other areas in response to emerging data on environmental constraints such as proximity to fragile habitats, sensitive species, or high cumulative impacts. An adaptive management system has been identified as a vital strategy to address scientific uncertainty of ecological impacts of deep-sea mining. The design features dynamic mine planning, scenario modeling, and impact forecasting. Also, operating data will be transparently viewable in a publicly available dashboard. This paper describes an implementation of a threshold-based framework for an effective adaptive management system designed to leverage the unique characteristics inherent to the resource.

Abstract BackgroundA worldwide pandemic of a new and unknown virus is characterised by scientific uncertainty. Yet, health authorities still need to communicate complex health risk information to the public – despite this uncertainty. The mental models approach to risk communication describes how people perceive and make decisions regarding complex risks, with the aim of identifying decision-relevant information that can be targeted in risk communication interventions. This study used COVID-19 as a case to explore how people make sense of scientific information and apply it to their lives and behaviour using the concept of mental models.MethodsThis qualitative study included 15 male and female participants of different ages and from different geographical regions in Norway, occupational areas and with different education levels. The participants were interviewed individually, and the interview data analysed via directed content analysis, with predetermined themes and codes derived the Norwegian Institute of Public Health’s official website. Materials in the interview data not represented by deductive codes were coded inductively. The participants’ perceptions and behaviours related to health risk information were analysed across three themes: virus transmission, exposure to risk and consequences of COVID-19. ResultsThe results imply that people put different meanings to the medical and scientific words used by experts to explain the pandemic, e.g. virus transmission and the reproduction number. And while some people expressed the need to comprehend why certain behavior and activities involve a high risk, others preferred simple, clear messages focusing on what to do and how to protect themselves. Similarly, information about health consequences caused panic for some and awareness for others. ConclusionThere is no one-size fits all to public health risk communication, and empowering people with decision-relevant information necessitates targeted and balanced risk communication.

All sciences, including biological science, have uncertainty, and they complicate theoretical questions. Uncertainty essentially is a mark of good science, and its efficacious communication is even essential for better decisions. Explaining the research work uncertainties indicates that the scientists are aware of the vital difference between the known and the unknown. Uncertainty is equally significant in biodiversity studies. Species composition of any area can’t be predicted with certainty because of interwoven relationships between species diversity and climatic and anthropogenic factors. Good survey planning with acceptable animal welfare practices could lead to asymptote for inventory of any particular area. Scientists can handle uncertainty in their studies by sensible statistics and reasonably large sample size.

Abstract   The COVID-19 pandemic has revealed many gaps and vulnerabilities in health systems and pandemic preparedness in European countries. It has also led to innovation and rapid improvements in certain elements of public health practice. One defining characteristic of the COVID-19 pandemic has been the rapid advance of scientific knowledge, accompanied by high degrees of scientific uncertainty. Each phase (or “wave”) of the pandemic has presented unique challenges. This workshop involves public health practitioners from multiple European countries. They will reflect upon some over-arching lessons learned through their experiences in the field, while also alluding to important innovations in public health that should be safeguarded for the future. The panellists will also discuss how lessons learned can be systematically identified and acted upon, through approaches such as after-action reviews (AARs), in order to optimise the public health response to the ongoing COVID-19 pandemic as well as to future ones. The panel discussion format of this workshop adds value to EUPHA 2021 participant through hearing, in a relatively informal format, the experiences from senior staff at national public health agencies from a variety of European countries and contexts. This approach keeps a coherence between speakers will also highlighting the unique challenges posed by specific national contexts. This workshop will also consider how processes such as AARs can be formalised to become routine aspects of public health practice. Particular attention will be paid to challenges and solutions that are similar across national boundaries. During the workshop, the moderator will ensure that the panelists responses are short and succinct. The final 15 minutes will be dedicated to questions from the audience. Speakers/Panelists Flavia Riccardo ISS, Rome, Italy Ute Rexroth RKI, Berlin, Germany Tanya Melillo Directorate of Health Promotion and Disease Prevention, MSIDA, Malta Mario Fafangel National Institute of Public Health, Ljubljana, Slovenia Key messages In order to guide the public health response to the COVID-19 pandemic as well as to future pandemics, it is essential to systematically identify lessons learned as well as innovative good practices. Identifying lessons learned, however, is only a first step as it is essential to develop action plans that are supported and endorsed across a wide range of stakeholders.
