World Glacier Monitoring Service. The World Glacier Monitoring Service (WGMS) was started in 1986, combining the two former services PSFG (Permanent Service on Fluctuations of Glaciers) and TTS/WGI (Temporal Technical Secretary/World Glacier Inventory). It is a service of the International Association of the Cryospheric Sciences of the ...
The lists include outlet glaciers, valley glaciers, cirque glaciers, tidewater glaciers and ice streams. Ice streams are a type of glacier [5] and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined ...

Laurentide ice sheet. The maximum extent of glacial ice in the north polar area during the Pleistocene period included the vast Laurentide ice sheet in eastern North America. The Laurentide ice sheet 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 ...
Quaternary glaciation. Extent of maximum glaciation (in black) in the Northern Hemisphere during the Pleistocene. The formation of 3 to 4 km (1.9 to 2.5 mi) thick ice sheets equate to a global sea level drop of about 120 m (390 ft) The Quaternary glaciation, also known as the Pleistocene glaciation, is an alternating series of glacial and ...
Stockholm Memorandum (2011) Scientists have affirmed that the planet has entered a new epoch, the Anthropocene. In the Anthropocene, humans have become the main agents of not only change to the Earth System but also the driver of Earth System rupture, disruption of the Earth System's ability to be resilient and recover from that change, potentially ultimately threatening planetary habitability ...
The Last Glacial Maximum map with vegetation types. Last Glacial Maximum refugia were places ( refugia) in which humans and other species survived during the Last Glacial Period, around 25,000 to 18,000 years ago. [1] Glacial refugia are areas that climate changes were not as severe, and where species could recolonize after deglaciation .
The World Food Prize was founded by Norman Borlaug, who received the Nobel Peace Prize in 1970 for his part in the Green Revolution, which dramatically increased crop yields and reduced the threat ...
