Ice-age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation. Individual pulses of cold climate within an ice age are termed ''glacial periods'' (or, alternatively, ''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called ''interglacials'' or ''interstadials''. In glaciology, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for the ...

Johann Wolfgang Von Goethe
Johann Wolfgang von Goethe (28 August 1749 – 22 March 1832) was a German poet, playwright, novelist, scientist, statesman, theatre director, and critic. His works include plays, poetry, literature, and aesthetic criticism, as well as treatises on botany, anatomy, and colour. He is widely regarded as the greatest and most influential writer in the German language, his work having a profound and wide-ranging influence on Western literary, political, and philosophical thought from the late 18th century to the present day.. Goethe took up residence in Weimar in November 1775 following the success of his first novel, ''The Sorrows of Young Werther'' (1774). He was ennobled by the Duke of Saxe-Weimar, Karl August, in 1782. Goethe was an early participant in the ''Sturm und Drang'' literary movement. During his first ten years in Weimar, Goethe became a member of the Duke's privy council (1776–1785), sat on the war and highway commissions, oversaw the reopening of silver min ...

Louis Agassiz
Jean Louis Rodolphe Agassiz ( ; ) FRS (For) FRSE (May 28, 1807 – December 14, 1873) was a Swiss-born American biologist and geologist who is recognized as a scholar of Earth's natural history. Spending his early life in Switzerland, he received a PhD at Erlangen and a medical degree in Munich.

Jostedalsbreen
Jostedal Glacier or is the largest glacier in continental Europe. It is in Vestland county in Western Norway. Jostedalsbreen lies in the municipalities of Luster, Norway, Luster, Sogndal, Sunnfjord (municipality), Sunnfjord, and Stryn. The highest peak in the area is Lodalskåpa at a height of . History In 1906, work was being done on footpaths that could accommodate tourists. Geography The Jostedal Glacier has a total area of . The highest point is Høgste Breakulen at above mean sea level. Branches of the glacier reach down into the valleys, for instance Bøyabreen in Fjærland and Nigardsbreen, both at above sea level. The thickest part of the glacier is . Jostedalsbreen has a length of a little more than and it is a part of the Jostedalsbreen National Park, which was established in 1991. The glacier covers over half of the national park. The glacier is maintained by the high snowfall rates in the region, not the cold temperatures. This means the glacier has high melt ...

Jens Esmark
Jens Esmark (31 January 1763 – 26 January 1839) was a Danish-Norwegian professor of mineralogy who contributed to many of the initial discoveries and conceptual analyses of glaciers, specifically the concept that glaciers had covered larger areas in the past. Biography Jens Esmark was born in Houlbjerg in Århus, Denmark. Esmark moved to Norway to the silver mining community of Kongsberg. He studied at the local mining academy. He completed his subsequent studies in Copenhagen and was accepted as a surveyor. Starting in 1797, Esmark was employed as a lecturer in mineralogy at the Kongsberg Mining Academy. In 1814, Esmark became Norway's first professor of geology as a professor of geology at the University of Oslo, and was described as "a pioneer in glacial geology", by professor of Quaternary geology and Glaciology Bjørn G. Andersen. In 1798, Esmark was the first person to ascend Snøhetta, highest in the mountain range Dovrefjell in southern Norway. The same year he l ...

Göran Wahlenberg
Georg (Göran) Wahlenberg (1 October 1780 – 22 March 1851) was a Sweden, Swedish natural history, naturalist. He was born in Filipstad Municipality, Kroppa, Värmland County. Wahlenberg matriculated at Uppsala University in 1792, received his doctorate in Medicine in 1806, was appointed ''botanices demonstrator'' in 1814, and professor of medicine and botany in 1829, succeeding Carl Peter Thunberg.

James Hutton
James Hutton (; 3 June O.S.172614 June 1726 New Style. – 26 March 1797) was a Scottish geologist, agriculturalist, chemical manufacturer, naturalist and physician. Often referred to as the father of modern geology, he played a key role in establishing geology as a modern science. Hutton advanced the idea that the physical world's remote history can be inferred from evidence in present-day rocks. Through his study of features in the landscape and coastlines of his native Scottish lowlands, such as Salisbury Crags or Siccar Point, he developed the theory that geological features could not be static but underwent continuing transformation over indefinitely long periods of time. From this he argued, in agreement with many other early geologists, that the Earth could not be young. He was one of the earliest proponents of what in the 1830s became known as uniformitarianism, the science which explains features of the Earth's crust as the outcome of continuing natural processes ...
