The need to predict ecological change in an era of major disruptions in both land cover and climate has revealed the inadequacy of contemporary ecology to address this challenge. Although we are increasingly improving our understanding of the diverse and disparate ecological consequences of large-scale ocean energy anomalies associated with sea surface temperatures, such as those of El Niño Southern Oscillation, our understanding of how energy anomalies from land surface change in one region influence another region is in its infancy. Modeling studies are revealing tantalizing suggestions that vegetation-atmosphere feedbacks, such as those created through large-scale alterations in tree cover, link the fates of forests across immense scales—regions to even continents. Unraveling these intra- and inter-continental scale connectivities in an ecological context—the emerging frontier of ecoclimate teleconnections—requires understanding a full spectrum of connectivity: “How do changes in vegetation in one region influence climate in that same region?”; “When, where, and specifically how are such climate influences teleconnected via atmospheric circulation to other regions?”; and “What are the resultant ecological consequences in disparate impacted regions?” This session will cover a broad range of topics addressing key components of ecoclimate teleconnections outlined by the three questions above and other related types of large-scale connectivity. The consequences of ecoclimate teleconnections could be profound, potentially impacting primary productivity, ecohydrology, biogeochemistry, and biodiversity in disparate regions. As we attempt globally-coordinated carbon management for the first time (post COP21 Paris), understanding ecoclimate teleconnections is not simply of academic interest but rather of paramount importance.
