Locations of palaeoclimatic temperature proxy records in the high-northern latitudes and Arctic as compiled by the PAGES 2k Consortium (2013), and superimposed on the boreal forest composition and the large river systems after Hellmann et al. (2013)
Abstract:
Today, there are only a handful of millennial-long and annually resolved tree-ring chronologies in existence. Explicit gaps in the global distribution of these regional chronologies together with an overall declining sample size back in time compel a community-wide challenge to discover new tree ring–based climate proxy records. Here, we present evidence for a yet unexplored palaeoenvironmental archive, define allied research tasks and emphasize probable hurdles within and beyond academia, in pursuit of answering this challenge.
