A less severe cold period or ice age is shown during the Jurassic-Cretaceous (150 Ma). There have been five or six major ice ages in the history of Earth over the past 3 billion years. The Late Cenozoic Ice Age began 34 million years ago, its latest phase being the Quaternary glaciation, in progress since 2.58 million years ago.
The split of the A38-B iceberg is recorded in this series of images. The iceberg was originally part of the massive A-38 iceberg, which broke from the Ronne Ice Shelf in Antarctica [3] B-15A: 6,400 2002 Northern edge of Iceberg B-15A in the Ross Sea, Antarctica, 29 January 2002: A-68: 5,800 175 50 2017 Calving crack in the Larsen C ice shelf [2 ...
Arctic sea ice has been monitored by satellites since 1979, [8] and has been recorded to be melting away every decade. [9] [10] The ice sheets are becoming thinner and younger, indicating increasing fragility. [11] The major threats are emissions from greenhouse gases and fossil fuels that are primary causes of global warming.
Currently, 28% of Arctic basin sea ice is multi-year ice, [2] thicker than seasonal ice: up to 3–4 m (9.8–13.1 ft) thick over large areas, with ridges up to 20 m (65.6 ft) thick. Besides the regular seasonal cycle there has been an underlying trend of declining sea ice in the Arctic in recent decades as well.
Northern edge of Iceberg B-15A in the Ross Sea, Antarctica, 29 January 2001. Iceberg B-15 was the largest recorded iceberg by area. [Note 1] It measured around 295 by 37 kilometres (159 by 20 nautical miles), with a surface area of 11,000 square kilometres (3,200 square nautical miles), about the size of the island of Jamaica.
The Laurentide ice sheet (LIS) was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States, multiple times during the Quaternary glaciation epochs, from 2.58 million years ago to the present.

The 'Spirit of Enderby has been conducting cruises to the Ross Sea region for many years, including McMurdo Sound. Although the Enderby has an ice-strengthened hull, the ship is not an icebreaker. The Enderby sports Zodiac inflatable boats, a hovercraft for Antarctica voyages, and all-terrain vehicles for over ice or overland travel.
