Climate Crisis

Abstract. In recent years, science has hardened the discourse on the emergency of global warming, pointing out that the next decades will be decisive to maintain the stability of the climate system, avoiding a cascade effect of events that increase the average temperature above safe limits. The scientific community warns that there are different tipping points that could produce a chain reaction in the global climate. One of them is related to the Jet Stream. But despite the importance of this air current in atmospheric dynamics in the Northern Hemisphere and the changes it is experiencing in the context of global warming, the public is still not familiar with this kind of physical concepts, nor with much simpler others. As concerns about the climate crisis rise, knowledge remains stagnant. To advance in the learning of the science of climate change, in general, and of concepts such as the Jet Stream, in particular, specific scientific communication formats are required that can successfully tackle the difficult task of explaining such complex problems to the general public. These formats should be included in the media because they are the main source for information on climate change and because their characteristics allow taking on the challenge. In this article we present a communication proposal existent in a newspaper published in Spain. We argue that this communication format represents a good model to disseminate climate science, educate readers and even to make physical concepts such as the Jet Stream accessible. We believe that this format conforms to and complies with the enunciation of Article 12 of the Paris Agreement, which calls on the signatory countries to promote education and training on climate change.

The ongoing COVID-19 outbreak pandemic is now a global crisis. It has caused 1.6+ million confirmed cases and 100 000+ deaths at the time of writing and triggered unprecedented preventative measures that have put a substantial portion of the global population under confinement, imposed isolation, and established ‘social distancing’ as a new global behavioral norm. The COVID-19 crisis has affected all aspects of everyday life and work, while also threatening the health of the global economy. This crisis offers also an unprecedented view of what the global climate crisis may look like. In fact, some of the parallels between the COVID-19 crisis and what we expect from the looming global climate emergency are remarkable. Reflecting upon the most challenging aspects of today’s crisis and how they compare with those expected from the climate change emergency may help us better prepare for the future.

AbstractImpacts on ecosystems and biodiversity are a prominent area of research in climate change. However, little is known about the effects of abrupt climate change and climate catastrophes on them. The probability of occurrence of such events is largely unknown but the associated risks could be large enough to influence global climate policy. Amphibians are indicators of ecosystems’ health and particularly sensitive to novel climate conditions. Using state-of-the-art climate model simulations, we present a global assessment of the effects of unabated global warming and a collapse of the Atlantic meridional overturning circulation (AMOC) on the distribution of 2509 amphibian species across six biogeographical realms and extinction risk categories. Global warming impacts are severe and strongly enhanced by additional and substantial AMOC weakening, showing tipping point behavior for many amphibian species. Further declines in climatically suitable areas are projected across multiple clades, and biogeographical regions. Species loss in regional assemblages is extensive across regions, with Neotropical, Nearctic and Palearctic regions being most affected. Results underline the need to expand existing knowledge about the consequences of climate catastrophes on human and natural systems to properly assess the risks of unabated warming and the benefits of active mitigation strategies.

AbstractDue to climate change the frequency and character of precipitation are changing as the hydrological cycle intensifies. With regards to snowfall, global warming has two opposing influences; increasing humidity enables intense snowfall, whereas higher temperatures decrease the likelihood of snowfall. Here we show an intensification of extreme snowfall across large areas of the Northern Hemisphere under future warming. This is robust across an ensemble of global climate models when they are bias-corrected with observational data. While mean daily snowfall decreases, both the 99th and the 99.9th percentiles of daily snowfall increase in many regions in the next decades, especially for Northern America and Asia. Additionally, the average intensity of snowfall events exceeding these percentiles as experienced historically increases in many regions. This is likely to pose a challenge to municipalities in mid to high latitudes. Overall, extreme snowfall events are likely to become an increasingly important impact of climate change in the next decades, even if they will become rarer, but not necessarily less intense, in the second half of the century.

Environmental Response

Average global temperatures are predicted to rise over the next century and changes in precipitation, humidity, and drought frequency will likely accompany this global warming. Understanding associated changes in continental precipitation and temperature patterns in response to global change is an important component of long-range environmental planning. For example, agricultural management plans that account for decreased precipitation over time will be less susceptible to the effects of drought through implementation of water conservation techniques.A detailed understanding of environmental response to past climate change is key to understanding environmental changes associated with global climate change. To this end, diatoms are sensitive to a variety of limnologic parameters, including nutrient concentration, light availability, and the ionic concentration and composition of the waters that they live in (e.g. salinity). Diatoms from numerous environments have been used to reconstruct paleosalinity levels, which in turn have been used as a proxy records for regional and local paleoprecipitation. Long-term records of salinity or paleoprecipitation are valuable in reconstructing Quaternary paleoclimate, and are important in terms of developing mitigation strategies for future global climate change. High-resolution paleoclimate records are also important in groundtruthing global climate simulations, especially in regions where the consequences of global warming may be severe.

Special Responsibility

Global climate change and its impacts have ethical dimensions, for instance carbon footprint equity concerns. World issues, including the state of the ecosphere and biodiver­sity, regularly see political leaders, NGOs, business representatives, religious/spiritual orga­nizations, academics, and others engage in international aviation-dependent meetings to address critical challenges facing humanity and the planet. Yet, climate scientists and advocates call for an 80% reduction in greenhouse gas (GHG) emissions by 2050 to cap the increase in global temperatures to 2ºC. Aviation emissions resulting from international meetings raise questions that are not silenced by GHG emissions offsetting. The era of climate change and ‘peak oil’ poses ethical challenges for holding international in-person religious and academic events, especially when the events propound an environmentalist concern and when aviation use is assumed. This paper raises ques­tions regarding the ecological impacts of large international events and focuses the ‘inconvenient truths’ associated with international aviation in the era of global warming. The Parliament of the World’s Religions, the largest multifaith gathering in the world, serves as a case study. The paper emphasizes the view that faith-based/faith-inspired organizations have a special responsibility for leadership in policy and praxis on the moral imperatives of sustainability, sustainable development and climate justice.

The insurance industry is rather effective in overcoming consequences of natural disasters. Insurance companies play a key role in financing natural disasters consequences, at the same time they sustain record losses and are in difficult financial conditions. Taking into account the above said, the issues of management of insurers risks is up-today and is connected with climate change. In article the content of “climate risk” as risk is specified, the emergence of which is caused by human activity, which leads to pollution, resulting from industrial activity and other sources that greenhouse gases (carbon dioxide) which are capable to absorb a range of infrared radiation generate and, as a result, predetermine warming of the global atmosphere that brings to change of structure of the world atmosphere and adds natural climate instability during the certain periods of time. The most destructive dangers threatening to mankind owing to global warming are systematized. Types of risks and their sphere of manifestation in Ukraine are outlined. The directions of adaptation of the insurance industry to changes, caused by climatic crisis are defined. Due to results of the research, the theoretical generalization and author’s solutions of a scientific task are offered, which appear in the development of scientific and methodical approaches and justification of practical recommendations about modernization of activity of insurance companies and reinsurers in the conditions of risks, generated by global climate changes. Scientific novelty of the research: specifying the role of the insurance industry regarding the prevention of risks connected with global warming.

Abstract. The Indian summer monsoon is an integral part of the global climate system. As its seasonal rainfall plays a crucial role in India's agriculture and shapes many other aspects of life, it affects the livelihood of a fifth of the world's population. It is therefore highly relevant to assess its change under potential future climate change. Global climate models within the Coupled Model Intercomparison Project Phase 5 (CMIP-5) indicated a consistent increase in monsoon rainfall and its variability under global warming. Since the range of the results of CMIP-5 was still large and the confidence in the models was limited due to partly poor representation of observed rainfall, the updates within the latest generation of climate models in CMIP-6 are of interest. Here, we analyse 32 models of the latest CMIP-6 exercise with regard to their annual mean monsoon rainfall and its variability. All of these models show a substantial increase in June-to-September (JJAS) mean rainfall under unabated climate change (SSP5-8.5) and most do also for the other three Shared Socioeconomic Pathways analyzed (SSP1-2.6, SSP2-4.5, SSP3-7.0). Moreover, the simulation ensemble indicates a linear dependence of rainfall on global mean temperature with high agreement between the models and independent of the SSP; the multi-model mean for JJAS projects an increase of 0.33 mm/day and 5.3 % per degree of global warming. This is significantly higher than in the CMIP-5 projections. Most models project that the increase will contribute to the precipitation especially in the Himalaya region and to the northeast of the Bay of Bengal, as well as the west coast of India. Interannual variability is found to be increasing in the higher-warming scenarios by almost all models. The CMIP-6 simulations largely confirm the findings from CMIP-5 models, but show an increased robustness across models with reduced uncertainties and updated magnitudes towards a stronger increase in monsoon rainfall.

Climate Crisis

Climate change and its global impact on all people, especially the marginalized communities, is widely recognized as the biggest crisis of our time. It is a context that invites all subjects and disciplines to bring their resources in diagnosing the problem and seeking the healing of the Earth. The African continent, especially its women, constitute the subalterns of global climate crisis. Can they speak? If they speak, can they be heard? Both the Earth and the Africa have been identified with the adjective “Mother.” This gender identity tells tales in patriarchal and imperial worlds that use the female gender to signal legitimation of oppression and exploitation. In this volume, African women theologians and their female-identifying colleagues, struggle with reading and interpreting religious texts in the context of environmental crisis that are threatening life on Earth. The chapters interrogate how biblical texts and African cultural resources imagine the Earth and our relationship with the Earth: Do these texts offer readers windows of hope for re-imagining liberating relationship with the Earth? How do they intersect with gender, race, empire, ethnicity, sexuality among others? Beginning with Genesis, journeying through Exodus, Ruth, Ecclesiastes and the Gospel of John, the authors seek to read in solidarity with the Earth, for the healing of the whole Earth community.

Climate Crisis

AbstractCOVID-19 has caused 100s of millions of infections and millions of deaths worldwide, overwhelming health and economic capacities in many countries and at multiple scales. The immediacy and magnitude of this crisis has resulted in government officials, practitioners and applied scholars turning to reflexive learning exercises to generate insights for managing the reverberating effects of this disease as well as the next inevitable pandemic. We contribute to both tasks by assessing COVID-19 as a “super wicked” problem denoted by four features we originally formulated to describe the climate crisis: time is running out, no central authority, those causing the problem also want to solve it, and policies irrationally discount the future (Levin et al. in Playing it forward: path dependency, progressive incrementalism, and the “super wicked” problem of global climate change, 2007; Levin et al. in Playing it forward: Path dependency, progressive incrementalism, and the "super wicked" problem of global climate change, 2009; Levin et al. in Policy Sci 45(2):123–152, 2012). Doing so leads us to identify three overarching imperatives critical for pandemic management. First, similar to requirements to address the climate crisis, policy makers must establish and maintain durable policy objectives. Second, in contrast to climate, management responses must always allow for swift changes in policy settings and calibrations given rapid and evolving knowledge about a particular disease’s epidemiology. Third, analogous to, but with swifter effects than climate, wide-ranging global efforts, if well designed, will dramatically reduce domestic costs and resource requirements by curbing the spread of the disease and/or fostering relevant knowledge for managing containment and eradication. Accomplishing these tasks requires building the analytic capacity for engaging in reflexive anticipatory policy design exercises aimed at maintaining, or building, life-saving thermostatic institutions at the global and domestic levels.
