Signatures of Climate on Earth's Surface
Session ID#: 76537
Session Description:
Climate affects the physical, biological, and geochemical processes that shape landscapes and and promote climate feedbacks. These effects are manifest in myriad multiscale problems in a range of environments, and include altering the magnitude, frequency, and/or intensity of innumerable natural processes. Signatures of climate are observed at all scales, where modifications of natural processes, such as changes in hurricane and flood magnitudes, sea level rise, the timing of snowmelt, wildfire, drought, or permafrost thaw can have profound impacts. This session welcomes submissions investigating manifestations of climate and/or climate change in physical, biological, and geochemical surface processes across all timescales. We encourage studies using experimental, modeling, field, and/or remote sensing techniques, including interpretations of past climate in the stratigraphic record. We aim to create a diverse, interdisciplinary session representing the broad range of research into the impacts of climate and climate change on the Earth’s surface.
