Ice Age

An ice age, or more precisely, a glacial age, is a period of long-term reduction in the temperature of the Earth's surface and atmosphere, resulting in the presence or expansion of continental ice sheets, polar ice sheets and alpine glaciers. Within a long-term ice age, individual pulses of cold climate are termed "glacial periods" (or alternatively "glacials" or "glaciations" or colloquially as "ice age"), and intermittent warm periods are called "interglacials". Glaciologically, ice age implies the presence of extensive ice sheets in the northern and southern hemispheres. By this definition, we are still in the ice age that began 2.6 million years ago at the start of the Pleistocene epoch, because the Greenland and Antarctic ice sheets still exist.

    For each age is a dream that is dying,
    Or one that is coming to birth.
    —Arthur William Edgar O’Shaughnessy (1844–1881)

    People in Stamps used to say that the whites in our town were so prejudiced that a Negro couldn’t buy vanilla ice cream. Except on July Fourth. Other days he had to be satisfied with chocolate.
