Climate and Environmental Crises (2020)
in: Oxford Research Encyclopedia of Politics
Climate change is increasingly being framed as a "climate crisis." Such a crisis could be viewed both to unfold in the climate system, as well as to be induced by it in diverse areas of society. Following from current understandings of modern crises, it is clear that climate change indeed can be defined as a "crisis." As the Intergovernmental Panel on Climate Change 1.5oC special report elaborates, the repercussions of a warming planet include increased food insecurity, increased frequency and intensity of severe droughts, extreme heat waves, the loss of coral reef ecosystems and associated marine species, and more. It is also important to note that a range of possible climate-induced crises (through, e.g., possible increased food insecurity and weather extremes) will not be distributed evenly, but will instead disproportionally affect already vulnerable social groups, communities, and countries in detrimental ways.The multifaceted dimensions of climate change allow for multiple interpretations and framings of "climate crisis," thereby forcing us to acknowledge the deeply contextual nature of what is understood as a "crisis." Climate change and its associated crises display a number of challenging properties that stem from its connections to basically all sectors in society, its propensity to induce and in itself embed nonlinear changes such as "tipping points" and cascading shocks, and its unique and challenging long-term temporal dimensions. The latter pose particularly difficult decision-making and institutional challenges because initial conditions (in this case, carbon dioxide emissions) do not result in immediate or proportional responses (say, global temperature anomalies), but instead play out through feedbacks among the climate system, oceans, the cryosphere, and changes in forest biomes, with some considerable delays in time. Additional challenges emerge from the fact that early warnings of pending so-called "catastrophic shifts" face numerous obstacles, and that early responses are undermined by a lack of knowledge, complex causality, and severe coordination challenges.
