we require geological we require geological mapping to fulfill our mapping to fulfill our objectivesobjectives
geology explains earth system linkages, climate geology explains earth system linkages, climate processes, & carbon sources/sinksprocesses, & carbon sources/sinks
geology guides work on natural records that document geology guides work on natural records that document variability, drivers, extreme events, & regional impactsvariability, drivers, extreme events, & regional impacts
geology will guide carbon capture and storage by deep geology will guide carbon capture and storage by deep geologic sequestrationgeologic sequestration
geology identifies thresholds & vulnerabilities in geology identifies thresholds & vulnerabilities in coastal zone dynamics, sea level change, permafrost coastal zone dynamics, sea level change, permafrost degradation, reduced glacier cover, groundwater quality degradation, reduced glacier cover, groundwater quality and quantity, flooding, dust storms and landslidesand quantity, flooding, dust storms and landslides
