New reconstructions of summer temperature patterns for the last 1000 years

Pattern of average summer temperature cooling following major tropical volcanic eruptions

New reconstructions of summer temperature patterns over the Northern Hemisphere land surface are being published in the 1 May 2017 issue of the journal Quaternary Science Reviews.  These are based on an extensive network of tree-ring records (combining the width of annual growth rings with the density and colour of the wood in each rings), and have been produced for every individual year from 750 to 1988.  The work is a result of the N-TREND consortium of dendroclimatologists, which includes participants from the Climatic Research Unit at UEA.
