Abrupt climate change: can society cope?
1Tyndall Centre for Climate Change Research, University of East Anglia, Norwich NR4 7TJ, UK.
Summary
Abrupt climate change, like a thermohaline circulation (THC) collapse, poses unique societal challenges. Understanding its unpredictable nature is crucial for effective climate adaptation and policy, especially for the UK and northwest Europe.
Area of Science:
- Climate Science
- Earth System Science
- Social and Behavioral Science
Background:
- Abrupt climate change is often overlooked in climate impact analyses and adaptation strategies.
- The potential for abrupt climate change influences debates on the urgency and scale of climate mitigation efforts.
- Societal implications of abrupt climate change, particularly for the UK and northwest Europe, require deeper investigation beyond economic and ecological perspectives.
Purpose of the Study:
- To explore the societal implications of abrupt climate change, focusing on the UK and northwest Europe.
- To examine the nature of abrupt climate change and its various definitions and perceptions.
- To review existing speculative work on abrupt climate change impacts and introduce social and behavioral science perspectives.
Main Methods:
- Review of existing literature on abrupt climate change and its societal impacts.
- Analysis of abrupt climate change definitions and perceptions.
- Case study focusing on the potential collapse of the thermohaline circulation (THC) and its implications for northwest Europe.
Main Results:
- Adaptation strategies can proceed within existing paradigms if abrupt climate change involves extreme events or accelerated unidirectional change.
- A directional climate shift, such as from a THC collapse, presents significant challenges: reversal of anticipated changes and unknown probabilities.
- Current understanding of abrupt climate change impacts is largely speculative and lacks comprehensive social and behavioral science insights.
Conclusions:
- It is premature to definitively label abrupt climate change as imposing unacceptable costs or constituting a dangerous, avoidable climate change.
- The fundamental problems of unpredictable reversals and unknown probabilities associated with directional abrupt climate change require further research.
- Future climate policy and decision-making need to better incorporate the uncertainties and potential societal consequences of abrupt climate change.

01:16What is Climate?
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.
01:50Global Climate Change
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
01:50Threats to Biodiversity
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
01:57Adaptations that Reduce Water Loss
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
02:41Responses to Drought and Flooding
Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
01:27Microbes and Climate Change
Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...
