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. Researcher Robert Felix speaks about climate and the possibility we could be heading into an ice age. According to a study, the Himalayas have lost no ice in the last 10 years, and glaciers are growing in areas such as Mount Everest, he noted. Ice age cycles occur around every 11,500 years, and one sign that one is impending is increased volcanic activity, particularly underwater, he stated.
