Bette L. Otto-Bliesner

From EverybodyWiki Bios & Wiki
DGG Is this a question about her notability? In addition to her position as one of the lead authors of the two IPCC chapter (she is not just a contributor, though I appear to have used the IPCC citation template incorrectly), she meets criteria #3 of WP:PROF because she is a fellow of two scholarly societies (the American Geophysical Union and the American Meteorological Society). And, once I finish the section on her research, it will be clear that she meets criteria #1 because her research has had an impact on her discipline. I will finish that section before I move the article to the mainspace. DaffodilOcean (talk) 21:33, 28 June 2021 (UTC)

Bette Otto-Bliesner is an earth scientist known for her modeling of Earth's past climate and its changes over different geological eras.

Education and career[edit]

Otto-Bliesner graduated from William Fremd High School in Palatine, Illinois in 1968.[2] She has a B.S. in meteorology from the University of Madison-Wisconsin (1972).[1] In 1974, she earned her M.S. from University of Wisconsin - Madison with a thesis titled "Isentropically time-averaged mass circulations in the Northern Hemisphere".[3] She earned her Ph.D. from the University of Wisconsin-Madison in 1980,[4] and was an associate scientist there from 1980 to 1986.[5] After two years as a contract scientist at ARC Technologies, Otto-Bliesner joined the Department of Geology at the University of Texas at Arlington where she worked from 1990 to 1996. She joined the National Center for Atmospheric Research (NCAR) in 1997 where she was promoted to senior scientist in 2007.[5]

Otto-Bliesner has worked on multiple chapters in the in the Assessment Review reports from the Intergovernmental Panel on Climate Change.[6] She was one of the lead authors on the 2007 chapter on "Paleoclimate" (IPCC AR4 WG1 Ch6 2007),[7][5] which was awarded the 2007 Nobel Peace Prize.[8] She was also a lead author on the 2013 chapter on "Information from the Paleoclimate Archives" (IPCC AR5 WG1 Ch5 2013).[9]


Otto-Bliesner's research connects paleogeographic information with global climate models. Through this approach, she has examined interactions between continental weathering and atmospheric carbon dioxide levels in the period from 570 to 425 million years ago,[10] revealed that deciduous forests help regulate temperatures in the Cretaceous period,[11] and identified factors leading to the persistence of snow on continental ice sheets.[12] Her modeling work has also assessed temporal variability in El Niño/La Niña cycles[13][14] and regional summer monsoons.[15] Through models jointly considering atmospheric conditions and the ocean, Otto-Bliesner's research has linked deep ocean circulation and global climate in the late Cretaceous (80 million years ago)[16] and the Last Glacial Maximum.[17][18][19][20] This research focus has revealed that changes in the Atlantic Meridional Overturning Circulation are linked freshwater input into the ocean[21][22] and the Bølling-Allerød warming at the end of the last glacial period.[23] Through a combination of direct samplling and modeling, her research has detailed the forcing that led to the Little Ice Age.[24][25] In polar regions, Otto-Bliesner has modeled variability in Arctic temperatures[26] which result in the retreat[27] or collapse[28] of polar ice sheets followed by increases in sea level.[29][30]

Otto-Bliesner also works on developing the methods used to establish climate models and through this has enabled low-resolution depictions of atmospheric conditions that can be coupled with high-resolution circulation models.[31][32] Through collaborative analysis of the effectiveness of climate models, Otto-Bliesner has examined the connections between greenhouse gasses and global warming,[33][34] she has weighed the impact of the sun, volcanic ash, and greenhouse gasses on temperatures on Earth[35] and she participated in projects that evaluate climate models through comparisons with paleoclimate data.[36][37][38] Most recently, she helped establish the framework of the Community Earth System Model that links model forcing parameters with data from the last thousand years.[39]
