Source-derived summary

Lonnie Thompson (born July 1, 1948) is an American paleoclimatologist and university professor in the School of Earth Sciences at Ohio State University. He has achieved global recognition for his drilling and analysis of ice cores from ice caps and mountain glaciers in the tropical and sub-tropical regions of the world. He and his wife, Ellen Mosley-Thompson, run the ice core paleoclimatology research group at the Byrd Polar Research Center.

Early life and education

Thompson was born July 1, 1948, in Gassaway, West Virginia, and was raised there on a farm. He obtained an undergraduate degree from Marshall University, majoring in geology. He subsequently attended Ohio State University where he received M.S. and Ph.D. degrees in geology.

Career and impact

Thompson is one of the world’s foremost authorities on paleoclimatology and glaciology. For over 40 years, he has led 60 expeditions where they conduct ice-core drilling programs in the Polar Regions as well as on tropical and subtropical ice fields in 16 countries including China, Peru, Russia, Tanzania and Papua, Indonesia (New Guinea). He and his team from the Ohio State University have developed light-weight solar-powered drilling equipment for acquisition of histories from ice fields in the tropical South American Andes, the Himalayas, and on Mount Kilimanjaro in Tanzania. The results from these paleoclimate histories were published in more than 230 articles and have contributed toward improved understanding of Earth’s climate system, both past and present.

Editorial analysis

Why this record matters

The phrase “american paleoclimatologist” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q897871. VIAF identifies the subject as 47019681. The Library of Congress control number is n2004007566. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1948.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
