Delivering sustainable climate action: reframing the sustainable development goals
Globally, climate change represents the most significant threat to the environment and socio-economic development, endangering lives and livelihoods. Within the UN’s current 17 Sustainable Development Goals (SDGs), climate action is explicitly covered under Goal 13, “to take urgent action to combat climate change and its impacts”. This perspective considers how to re-frame the SDGs and their successor towards mainstreaming climate action within the targets and indicators of all the development goals.
Cardiovascular health (“Life’s Essential 8”), risk of depression and anxiety: a prospective cohort study
There is a growing interest in the linkage of cardiovascular health (CVH) with depression/anxiety but the evidence of “Life’s Essential 8” CVH score is scarce. We evaluated the associations of CVH score with risk of incident depression/anxiety among ~0.4 million participants. During follow-up, 17,554 incident events with symptoms of either disorder were recorded. Per 100-point decrease in CVH score was associated with an increased risk of incident either disorder (Hazard ratio [HR] = 1.133, 95% confidence interval [CI]:1.114–1.153), depression (HR = 1.205, 95% CI:1.180–1.231), and anxiety (HR = 1.042, 95% CI:1.017–1.069). Per 100-point decrease in health assessments or health behaviors was associated with an increased risk of incident either disorder (HRhealth assessments = 1.085, 95% CI: 1.058–1.113, HRhealth behaviors = 1.217, 95% CI: 1.186–1.250). Poor CVH is a risk factor for the incident late-life depression/anxiety symptoms of middle-aged and older adults, and healthy behaviors could be targeted for the risk assessment and intervention of depression/anxiety.
Video communication, blue marble awe, and attitudes toward climate change and renewable energy
We conducted a survey experiment to examine how respondents’ attitudes toward climate change and renewable energy are affected by six communication approaches using online videos. Three interventions used single message approaches, which focused on facts about climate change science, facts about solar PV technology, or the emotion of blue marble awe (the feeling of awe for the Earth arising from the realization that we live on a fragile planet). Two interventions used dual message approaches, which combined blue marble awe with either climate change science or solar PV technology facts. One intervention used a dual reinforced message approach, which combined blue marble awe, solar PV technology facts, and a message from an astronaut who is an ambassador for renewable energy. Results show that the dual reinforced message approach has the strongest effects on energy and environmental attitudes. Our findings offer important lessons for scientists and educators interested in energy communication.
Machine learning map of climate policy literature reveals disparities between scientific attention, policy density, and emissions
Current climate mitigation policies are not sufficient to meet the Paris temperature target, and ramping up efforts will require rapid learning from the scientific literature on climate policies. This literature is vast and widely dispersed, as well as hard to define and categorise, hampering systematic efforts to learn from it. We use a machine learning pipeline using transformer-based language models to systematically map the relevant scientific literature on climate policies at scale and in real-time. Our “living systematic map” of climate policy research features a set of 84,990 papers, and classifies each of them by policy instrument type, sector, and geography. We explore how the distribution of these papers varies across countries, and compare this to the distribution of emissions and enacted climate policies. Results suggests a potential stark under-representation of industry sector policies, as well as diverging attention between science and policy with respect to economic and regulatory instruments.
Theorising unconventional climate advocates and their relationship to the environmental movement
Environmentalist-identified advocates have contributed to high levels of public support for climate action across countries. However, there remain important holdout constituencies that theory and evidence suggest are less likely to be persuaded by environmentalists, especially constituencies associated with resources and economic production, rural and regional areas, masculine norms, and conservative belief systems and politics. Emerging from these holdout constituencies, though, are some novel advocates for climate action. In this paper we theorise ‘unconventional climate advocates’ as those who combine advocacy for climate action with a social identity that departs from the prototypical environmentalist identity. Using social network analysis we show that unconventional climate advocates in Australia are peripheral to the main environmental movement, that is, the conventional advocates for climate action. We contend that unconventional advocates can broaden the social base of support for climate action, and their independence from conventional advocates – environmentalists – may aid in their efforts.
