Temperature is a proximal driver of many key soil physical, chemical, and biological processes.  Climate change is expected to increase soil temperature variability and the frequency and duration of extreme temperature events (e.g., severe frost).  Most existing ecosystem warming experiments focus on elevated temperature and apply a constant, long-term temperature increase (temperature press).  Fewer experimental field studies have been designed to address changes in temperature variability or extreme temperature events.  Results from existing warming studies will be synthesized and discussed in an extreme event context.
