Climate Change

The fact that a behavior can be instrumental for multiple goals does not logically entail that people are typically propelled into action for multiple reasons. On the contrary, goal-directed behavior in the real world is, in a given instance, aimed at one focal goal. In this article, I present the Campbell paradigm, in which a particular behavior is controlled by a single reason or goal. To identify the very reason (i.e.

How can we as individuals or groups mitigate climate change? One key issue is whether motives other than the pursuit of material self-interest can be used fruitfully to reduce climate change. In this article I describe recent research that supports three deeply rooted concerns: (a) concern with other humans (prosociality), (b) concern with equality (egalitarianism), and (c) concern with animals (as part of adherence to biospheric values).
Climate change's particular ‘perfect storm’ problem-nature requires educators and communicators to acknowledge that a single ‘silver bullet’ intervention that eliminates ignorance and denial regarding global warming may never emerge. However, diverse kinds of information-hunks and educational initiatives do incrementally increase acceptance (and alarm) regarding climate change, thus decreasing ignorance/denial.

The mounting research on consumer behavior and climate change is gradually improving our understanding of effective ways to mobilize consumers to mitigate climate change. The relationship between consumer behavior and climate change is complex and most consumers are not capable of determining which behavior changes are worth doing. Research has come a long way identifying the most impactful behavior changes, but more research is needed to refine and situate these insights.
Background: Climate change has important implications for the health and futures of children and young people, yet they have little power to limit its harm, making them vulnerable to climate anxiety. This is the first large-scale investigation of climate anxiety in children and young people globally and its relationship with perceived government response. Methods: We surveyed 10 000 children and young people (aged 16–25 years) in ten countries (Australia, Brazil, Finland, France, India, Nigeria, Philippines, Portugal, the UK, and the USA; 1000 participants per country).
Background: Previous studies focusing on urban, industrialised regions have found that excess heat exposure can increase all-cause mortality, heat-related illnesses, and occupational injuries. However, little research has examined how deforestation and climate change can adversely affect work conditions and population health in low latitude, industrialising countries. Methods: For this modelling study we used data at 1 km2 resolution to compare forest cover and temperature conditions in the Berau regency, Indonesia, between 2002 and 2018.

Left unabated, climate change will have catastrophic effects on the health of present and future generations. Such effects are already seen in Europe, through more frequent and severe extreme weather events, alterations to water and food systems, and changes in the environmental suitability for infectious diseases. As one of the largest current and historical contributors to greenhouse gases and the largest provider of financing for climate change mitigation and adaptation, Europe's response is crucial, for both human health and the planet.
Background: Adoption of healthy and sustainable diets could be essential for safe-guarding the Earth's natural resources and reducing diet-related mortality, but their adoption could be hampered if such diets proved to be more expensive and unaffordable for some populations. Therefore, we aimed to estimate the costs of healthy and sustainable diets around the world. Methods: In this modelling study, we used regionally comparable food prices from the International Comparison Program for 150 countries.
Background: Unhealthy diets, the rise of non-communicable diseases, and the declining health of the planet are highly intertwined, where food production and consumption are major drivers of increases in greenhouse gas emissions, substantial land use, and adverse health such as cancer and mortality. To assess the potential co-benefits from shifting to more sustainable diets, we aimed to investigate the associations of dietary greenhouse gas emissions and land use with all-cause and cause-specific mortality and cancer incidence rates.
Fish experiencing abnormally high or prolonged elevations in temperature can exhibit impaired reproduction, even for species adapted to warm water environments. Such high temperature inhibition of reproduction has been linked to diminished gonadal steroidogenesis, but the mechanisms whereby hypothalamic-pituitary-gonadal (HPG) axis signaling is impacted by high temperature are not fully understood.
