Ole Humlum (born 21 July 1949) is a Danish professor of physical geography at the University of Oslo, Department of Geosciences and adjunct professor of physical geography at the University Centre in Svalbard. His academic focus includes glacial and periglacial geomorphology and climatology.
Born near the coast in Jylland, he became interested in geology when he visited the Alps as a teenager and saw the glaciers. He studied natural science at the University of Copenhagen, earning bachelor's degrees in geology, geography, zoology and botany. In 1976, he obtained a M.Sc. in glacial geomorphology and was the same year also awarded a Prize Essay Gold Medal at the University for another study. He earned a Ph.D degreee in glacial geomorphology in 1980.
After having held post-doc positions 1980–1983 he became scientific director at the University of Copenhagen Arctic Station near Qeqertarsuaq where he lived for three years. He subsequently worked as assistant professor at the University of Copenhagen from 1986–1999.
He became professor at the University Centre in Svalbard in 1999. In 2003, he became full professor at the University of Oslo, Department of Geosciences. He became a member of the newly founded Norwegian Scientific Academy for Polar Research in 2008.
Climate change views
Humlum is a member of the Norwegian organization Climate Realists which opposes the scientific assessment of climate change that is expressed by the Intergovernmental Panel on Climate Change. He is active in Norwegian and Danish debate about the issue, arguing that current climate change is mainly a natural phenomenon. Together with Jan-Erik Solheim and Kjel Stordahl, he published the article "Identifying natural contributions to late Holocene climate change" in Global and Planetary Change in 2011. The article argued that changes in the sun's and moon's impact on earth explains most of both historical and current climate changes. The theory in the article was opposed by several scientists. He projected in 2013 that the climate most likely will become colder in the next 10–15 years.
