Apocalyptic impacts of climate change and ecological breakdown
Severe impacts of climate change can combine, including with climate-unrelated, concurrent risks such as worldwide pollution, fragility, resource depletion, political disenchantment, poverty or wealth inequality, and biotechnology risk, to result in a confluence of developments that cause a drastically aggravated impact on societies or humanity – such multiple concurrent crises are sometimes referred to as a "perfect storm". Climate change may also be considered as a threat multiplier "which exacerbates existing trends, tensions, and instability". Climate-related factors of a potential collapse may include famine (crop loss, drought), extreme weather (hurricanes, floods), war ([co-]caused by scarce resources) and conflict, systemic risk (relating to migration, famine, or conflict), and disease.Societal collapse
Research has shown that aside from worsening income inequality and the strain of an increased population exceeding the carrying capacity of an environment, another important factor which may lead to global collapse is ecological strain. Climate change increases the strain on the planet's ecology, especially in terms of resource depletion.Climate change has contributed to the collapse of civilisations in the past. A 200-year drought caused cities of the Indus Valley civilisation to be abandoned; the Khmer Empire collapsed as a result of successive droughts and monsoon floods which led to political and social unrest; and a period of cooling called the Little Ice Age made it more difficult for Vikings to farm in Greenland, which was one of the reasons that they were forced to abandon their settlements.More recently, a severe drought in the late 2000s which is likely to have been intensified by anthropogenic climate change contributed to failing agricultural production in Syria, leading to high unemployment, large amounts of internal displacement, heightened ethnic tensions and increased violence. Poor governance and neoliberal economic policies also contributed to the resulting civil war and societal collapse in 2011.Although the entire planet is affected by climate change, the worst impacts will be felt by the world's poorest countries, and these countries are both more likely to face the effects of societal collapse and more likely to face such effects sooner. This is one of the moral issues described within the climate justice movement of climate change activism.As societal collapse becomes more likely, it is possible that denial and anti-intellectualism will increase as well, or that people will assign blame for the crisis on communities other than their own. As localised violence increases, societal collapse also becomes more likely.
