The Business of Climate Transformation

Without deep transformations in the economy that go beyond incremental gains in decarbonization, we remain on course for catastrophic global heating. Some businesses have pledged to go carbon-neutral, carbon-trading schemes are expanding, and a growing divestment movement has pressured investment funds to shun fossil fuel producers. But financial forces are also part of the problem, still driving more production and consumption of fossil fuels. Achieving transformational shifts in finance, production, and governance calls for a more disruptive politics underpinned by shifts in power relations.

The Risks of Global Heating to Energy Systems and Energy Security

As recent events have shown, global heating is increasing the risk to many sectors of society, from agriculture to the built environment, to transportation. The energy security of most energy systems, regardless of their size, is also at risk from the effects of global heating: The reliable supply of power to end users can be threatened by extreme weather events affecting transformers and transmission and distribution networks. It can also be a threat to generators that are vulnerable to unpredictable supplies of water, such as thermal or hydroelectric generation facilities. In this paper, we use an energy security methodology to examine some of the possible climate risks to the supply of power from hydroelectricity produced by one of western Canada’s electricity suppliers. The work is of particular interest because it shows how the increasing number of heatwaves that are affecting parts of western Canada and the Pacific Northwest could affect electricity supply in some western Canadian provinces and northern U.S. states.

Climate Change and Major Pests of Mediterranean Olive Orchards: Are We Ready to Face the Global Heating?

Evidence of the impact of climate change on natural and agroecosystems is nowadays established worldwide, especially in the Mediterranean Basin, an area known to be very susceptible to heatwaves and drought. Olea europaea is one of the main income sources for the Mediterranean agroeconomy, and it is considered a sensitive indicator of the climate change degree because of the tight relationship between its biology and temperature trend. Despite the economic importance of the olive, few studies are nowadays available concerning the consequences that global heating may have on its major pests. Among the climatic parameters, temperature is the key one influencing the relation between the olive tree and its most threatening parasites, including Bactrocera oleae and Prays oleae. Therefore, several prediction models are based on this climatic parameter (e.g., cumulative degree day models). Even if the use of models could be a promising tool to improve pest control strategies and to safeguard the Mediterranean olive patrimony, they are not currently available for most O. europaea pests, and they have to be used considering their limits. This work stresses the lack of knowledge about the biology and the ethology of olive pests under a climate change scenario, inviting the scientific community to focus on the topic.

Dispatches from the age of fire

In 2019–2020, fires ravaged large areas of Australia devastating land, infrastructure and human and non-human lives. While Australia has a history of fires and fire management, large regions of the eastern states were devastated by super fires fueled by their own weather, and changes to the climate. However, Australian governments, political and business leaders continue to invest in fossil fuels and disregard the impact of the climate crisis. Meanwhile, the nation is at a tipping point due to the effects of global heating, extreme weather events, natural disasters and biodiversity loss. This article explores the climate crisis through a discussion of first-hand accounts of people directly affected by the 2019–2020 bushfires in Australia. These harrowing and philosophical accounts of the fires were gleaned from poetry, videos, websites and non-fiction sources and demonstrate the human lived experiences of the climate crisis and how we can move forward for climate justice.

The Impacts of Humans on Geomorphology

This chapter discusses the factors that have led to an increasing interest in the human impact in geomorphology, and then discusses the literature that appeared between c 1960 and 2000. These developments were in four main areas: (i) intellectual and policy-related (ii) technological developments that alter geomorphological processes (iii) demographic trends, and (iv) proliferation of techniques for the study of landform and process change. Much work was undertaken on landforms produced by construction and excavation. Interest also developed in accelerating ground subsidence, which is a widespread phenomenon that creates engineering problems. Indeed, with increasing exploitation of tundra areas for such activities as oil exploitation, there was an increasing interest in the problems associated with permafrost. Rivers have also been greatly impacted. Humans have modified sediment transport by rivers in two ways. First, as a result of accelerated soil erosion, the delivery of sediment to rivers has increased. Secondly, burgeoning dam construction has caused sediment to be trapped in reservoirs. Far-reaching changes in channel form have been produced by land-use and land-cover changes. In addition to non-deliberate changes to river systems, there have been a whole range of deliberate modifications (e.g. channelization). Some valley bottoms areas have suffered from accelerated sedimentation while others have become incised with gullies (arroyos). Studies have indicated an increasing incidence of mass movements. These have been attributed to such factors as deforestation, road cuts, changes in slope drainage and irrigation of farm land. Much work has also been undertaken on wind erosion of dryland surfaces. Human activities, most notably air pollution, have changed the nature and rate of weathering, though enhanced weathering by salt can also be accelerated by irrigation. Large numbers of people live in coastal zones and have had a major impact on coastal landforms and processes. Many of the world's shorelines have been eroding and the complex mix of causes, natural and anthropogenic, that could be responsible have been analysed. Finally, since the 1980s there has been a growing realisation of the importance of global heating for geomorphological phenomena.

Legitimacy and procedural justice: how might stratospheric aerosol injection function in the public interest?

The success of stratospheric aerosol injection (SAI) in limiting global heating requires the inclusion and maintenance of the political ideals of legitimacy and procedural justice. Without them, the prospects are slim that this institution can be developed and operated in the public interest in such a way that it will protect and promote social well-being by minimising climate-related harm. Long term legitimacy and procedural justice are crucial to several sensitive features of SAI. They relate to openness, inclusivity and independence, in dealing both with external issues of concern to stakeholders representing the general public and with internal issues concerning agents directly involved in SAI. This article begins by outlining notions of legitimacy and procedural justice, and the criteria appropriate for SAI. Then it investigates how the moral indications provided by the related standards might ensure that SAI is not distorted in such ways that it serves the selfish interests of private parties. Finally, the article outlines two governance recommendations for ensuring that legitimacy and procedural justice in SAI are achieved and maintained over time, so that it can work continuously in the public interest.

Who Cares? ―The COVID-19 Pandemic, Global Heating and the Future of Humanity1

The COVID-19 pandemic has engendered unprecedented drastic and costly measures to obviate the threat. Will something similar happen in relation to global heating? No, this is not likely. Mainly this has to do with a difference in the nature of collective action. Nation states protect their respective populations against the virus. With regard to global heating, we are facing the tragedy of the commons. No global government assumes responsibility for our common future. However, there may be another and further explanation lurking behind political inaction: many people, including our politicians, think that it does not matter if humanity goes extinct. It does matter, however. Strangely enough, the view that it matters is questioned by many important philosophers in the past and in the present, and it is hence controversial. Yet, it should be our common-sense stance to the problem. It is of the utmost importance that there will be sentient happy life on the globe for an indefinite time. Theoretically speaking, in order to recognize this, we need to accept some “total” view, implying what has been called the repugnant conclusion. Practically speaking, we should go to great length to rescue our human civilisation, even if this means that, for a while, we must endure all sorts of hardships such as a global enlightened despotism, or worse—a situation of life boat ethics.

Nuclear Deterrence—Another Perfect Storm

This chapter applies Stephen M. Gardiner’s model of the perfect moral storm to nuclear deterrence. Most damage from a major nuclear war would fall on third parties rather than the belligerents. Some would be present-day people in neutral countries and nonhuman animals, but future generations would be the largest group of victims. This makes ongoing reliance on large nuclear arsenals ethically indefensible. It presents many of the same problems, however, as global heating. One is that future damages are not salient to present-day publics and politicians. Another is that nuclear weapons reduce the probability of major war while greatly increasing the damage if it occurs. This affects the intergenerational distribution of costs and benefits. Nuclear deterrence is a ‘front-loaded’ good: its benefits arrive right away, whereas its costs will most likely arrive only in the future. Nuclear war is inevitable if states rely on it in perpetuity, but for a given generation, the likelihood may be small. “Business-as-usual” may thus be a good self-interested gamble for each generation until nuclear war actually occurs. Not surprisingly, it finds many defenders. The last part of the chapter considers possible solutions.
