Emotional signatures of climate policy support
2024-04-21 (or before) in PLOS - Open ScienceThe optimal emotional tone for climate communication has been debated by scholars and the press, but little is known about the effects of emotions on different types of policy support. In this paper we examine multiple discrete emotions people experience in reaction to climate change, and assess the strength of these emotions as predictors of support for different types of mitigation and adaptation policies. Using multi-wave, cross-sectional, nationally representative samples of American adults, we test whether guilt, anger, hope, fear, and sadness are uniquely associated with support for different types of climate policies.

Post-growth: A viable path to limiting global warming to 1.5°C
2024-02-08 (or before) in Cell PressExisting climate mitigation scenarios tend to project a high GDP growth, even though growth leads to increased energy use and emissions. We show that pathways of low growth make it possible to pursue ambitious mitigation with a slower build-up of low-carbon energy and lower improvements in energy efficiency. Low growth is typically associated with poverty and social challenges; however, we argue that novel post-growth interventions could decrease social inequalities while also helping to protect the climate.

It is clear that further action is needed to avoid the worst impacts of climate change and achieve a just climate future. Here, we offer a new perspective on emissions responsibility and climate finance by conducting an environmentally extended input output analysis that links 30 years (1990–2019) of United States (U.S.) household-level income data to the emissions generated in creating that income. To do this we draw on over 2.8 billion inter-sectoral tran...

On avoiding dangerous anthropogenic interference with the climate system: Formidable challenges ahead

The committed warming is inferred from the most recent Intergovernmental Panel on Climate Change (IPCC) estimates of the greenhouse forcing and climate sensitivity. The estimated warming of 2.4°C is the equilibrium warming above preindustrial temperatures that the world will observe even if GHG concentrations are held fixed at their 2005 concentration levels but without any other anthropogenic forc...

Of those only around 20 make realistic assumptions on mitigation options, for instance the rate and scale of carbon removal from the atmosphere or extent of tree planting, a new study shows. All 20 scenarios need to pull at least one mitigation lever at 'challenging' rather than 'reasonable' levels.

Business-as-usual will lead to super and ultra-extreme heatwaves in the Middle East and North Africa - npj Climate and Atmospheric Science
2021-03-23 in NatureGlobal climate projections suggest a significant intensification of summer heat extremes in the Middle East and North Africa (MENA). To assess regional impacts, and underpin mitigation and adaptation measures, robust information is required from climate downscaling studies, which has been lacking for the region. Here, we project future hot spells by using the Heat Wave Magnitude Index and a comprehensive ensemble of regional climate projections for MENA. Our results, for a business-as-usual pathway, indicate that in the second half of this century unprecedented super- and ultra-extreme heatwave conditions will emerge. These even...

Eco-reproductive concerns in the age of climate change - Climatic Change
2020-11-27 (or before) in Springer VerlagMedia reports and public polls suggest that young people in many countries are increasingly factoring climate change into their reproductive choices, but empirical evidence about this phenomenon is lacking. This article reviews the scholarship on this subject and discusses the results of the first empirical study focused on it, a quantitative and qualitative survey of 607 US-Americans between the ages of 27 and 45. While 59.8% of respondents reported being “very” or “extremely concerned” about the carbon footprint of procreation, 96.5% of respondents were “very” or “extremely concerned&r...

Approximate calculations of the net economic impact of global warming mitigation targets under heightened damage estimates
2020-10-09 (or before) in PLOS - Open ScienceEfforts to mitigate global warming are often justified through calculations of the economic damages that may occur absent mitigation. The earliest such damage estimates were speculative mathematical representations, but some more recent studies provide empirical estimates of damages on economic growth that accumulate over time and result in larger damages than those estimated previously. These heightened damage estimates have been used to suggest that limiting global warming this century to 1.5 °C avoids tens of trillions of 2010 US$ in damage to gross world product relative to limiting global warming to 2.0 °C. However,...

Fairly sharing 1.5: national fair shares of a 1.5 °C-compliant global mitigation effort - International Environmental Agreements: Politics, Law and Economics
2020-06-10 (or before) in Springer VerlagThe problem of fairly distributing the global mitigation effort is particularly important for the 1.5 °C temperature limitation objective, due to its rapidly depleting global carbon budget. Here, we present methodology and results of the first study examining national mitigation pledges presented at the 2015 Paris climate summit, relative to equity benchmarks and 1.5 °C-compliant global mitigation. Uniquely, pertinent ethical choices were made via deliberative processes of civil society organizations, resulting in an agreed range of effort-sharing parameters. Based on this, we quantified each country’s range of fai...

The role of climate change education on individual lifetime carbon emissions
2020-03-02 (or before) in email.mg1.substack.comStrategies to mitigate climate change often center on clean technologies, such as electric vehicles and solar panels, while the mitigation potential of a quality educational experience is rarely discussed. In this paper, we investigate the long-term impact that an intensive one-year university course had on individual carbon emissions by surveying students at least five years after having taken the course. A majority of course graduates reported pro-environmental decisions (i.e., type of car to buy, food choices) that they attributed at least in part to experiences gained in the course. Furthermore, our carbon footprint analysis...

Sandy coastlines under threat of erosion
2020-03-02 (or before) in NatureSandy beaches occupy more than one-third of the global coastline1 and have high socioeconomic value related to recreation, tourism and ecosystem services2. Beaches are the interface between land and ocean, providing coastal protection from marine storms and cyclones3. However the presence of sandy beaches cannot be taken for granted, as they are under constant change, driven by meteorological4,5, geological6 and anthropogenic factors1,7. A substantial proportion of the world’s sandy coastline is already eroding1,7, a situation that could be exacerbated by climate change8,9. Here, we show that ambient trends in shoreline dy...

Large loss of CO2 in winter observed across the northern permafrost region
2019-12-11 (or before) in NatureRecent warming in the Arctic, which has been amplified during the winter1–3, greatly enhances microbial decomposition of soil organic matter and subsequent release of carbon dioxide (CO2)4. However, the amount of CO2 released in winter is not known and has not been well represented by ecosystem models or empirically based estimates5,6. Here we synthesize regional in situ observations of CO2 flux from Arctic and boreal soils to assess current and future winter carbon losses from the northern permafrost domain. We estimate a contemporary loss of 1,662 TgC per year from the permafrost region during the winter season (O...

Bittersweet nature of nitrogen calls for better management practices
2019-10-23 (or before) in UN Environment ProgrammeNearly 80 per cent of the air we breathe is nitrogen, a harmless inert gas. However, nitrogen also combines with other atoms to form chemical compounds—known as “reactive nitrogen” or “fixed nitrogen” (Nr)—that are essential for life on Earth but, at high concentrations, also hugely damaging to the environment.

Macroeconomic and Financial Policies for Climate Change Mitigation: A Review of the Literature
2019-10-11 (or before) by in International Monetary FundClimate change is one of the greatest challenges of this century. Mitigation requires a large-scale transition to a low-carbon economy. This paper provides an overview of the rapidly growing literature on the role of macroeconomic and financial policy tools in enabling this transition. The literature provides a menu of policy tools for mitigation. A key conclusion is that fiscal tools are first in line and central, but can and may need to be complemented by financial and monetary policy instruments. Some tools and policies raise unanswered questions about policy tool assignment and mandates, which we describe. The literature is ...

RCP 8.5—A scenario of comparatively high greenhouse gas emissions - Climatic Change
2011-08-13 in Springer VerlagThis paper summarizes the main characteristics of the RCP8.5 scenario. The RCP8.5 combines assumptions about high population and relatively slow income growth with modest rates of technological change and energy intensity improvements, leading in the long term to high energy demand and GHG emissions in absence of climate change policies. Compared to the total set of Representative Concentration Pathways (RCPs), RCP8.5 thus corresponds to the pathway with the highest greenhouse gas emissions. Using the IIASA Integrated Assessment Framework and the MESSAGE model for the development of the RCP8.5, we focus in this paper on two impo...
