Permafrost & Periglacial Geologic Environments in Earth History: Discovering the Future By Linking The Present To The Past| PICO session
Convener: Reginald Muskett  | Co-Convener: Dongliang Luo 
We welcome research and science papers of recent progress on topics of the changes of the active-layer, permafrost, ground ice, rock glaciers, moraines and periglacial environments linking GNSS, aircraft-based and satellite-based remote sensing, geodesy with field measurements. We envision this session to showcase the newest developments, findings and studies integrating topics from the biological, climatological, geophysical, hydrological and meteorological sciences at the scales of sites, landscapes and regions of our Holocene Earth.

Over Earth’s long 4.8 billion year history there are several recognized glacial periods like the present from the evidence of rock outcrop exposures. This very old evidence lead to Alfred Wagener’s theory of Continental Drift and the publication with Milutin Milanković “The Climates of the Geological Past” (Die Klimate der geologischen Vorzeit), and which with our modern geophysics methods and techniques in the fields of geochronology, paleomagnetism and seismology became the foundation of the Plate Tectonics Paradigm. In this context did the rise of the Qinghai-Tibet Plateau (the ‘Third Pole’ of Earth) from the collision of the Eurasian and India plates coincide with the 100,000 year Milanković cycles to initiate the Quaternary glaciations and how did plate tectonics influence the Mesozoic, Paleozoic and Precambrian glaciations? We cannot predict the future; Therefore, we use the past Geologic evidence to guide our thoughts and test our present day hypotheses.
