Observed and Expected Effects On Social Systems

Further information: Effects of global warming#Social systems and Regional effects of global warming#Regional impacts

Vulnerability of human societies to climate change mainly lies in the effects of extreme-weather events rather than gradual climate change. Impacts of climate change so far include adverse effects on small islands, adverse effects on indigenous populations in high-latitude areas, and small but discernable effects on human health. Over the 21st century, climate change is likely to adversely affect hundreds of millions of people through increased coastal flooding, reductions in water supplies, increased malnutrition and increased health impacts. Most economic studies suggest losses of world gross domestic product (GDP) for this magnitude of warming.

    “I ... observed the great beauty of American government to be, that the simple machines of representation, carried through all its parts, gives facility for a being moulded at will to fit with the knowledge of the age; that thus, although it should be imperfect in any or all of its parts, it bears within it a perfect principle the principle of improvement.
    ”
    —Frances Wright (1795–1852)

    “At times it seems that the media have become the mainstream culture in children’s lives. Parents have become the alternative. Americans once expected parents to raise their children in accordance with the dominant cultural messages. Today they are expected to raise their children in opposition to it.”
    —Ellen Goodman (20th century)

    “Perspective, as its inventor remarked, is a beautiful thing. What horrors of damp huts, where human beings languish, may not become picturesque through aerial distance! What hymning of cancerous vices may we not languish over as sublimest art in the safe remoteness of a strange language and artificial phrase! Yet we keep a repugnance to rheumatism and other painful effects when presented in our personal experience.”
    —George Eliot [Mary Ann (or Marian)

    “Just as it is true that a stream cannot rise above its source, so it is true that a national literature cannot rise above the moral level of the social conditions of the people from whom it derives its inspiration.”
    —James Connolly (1870–1916)

    “What avails it that you are a Christian, if you are not purer than the heathen, if you deny yourself no more, if you are not more religious? I know of many systems of religion esteemed heathenish whose precepts fill the reader with shame, and provoke him to new endeavors, though it be to the performance of rites merely.”
    —Henry David Thoreau (1817–1862)
