Juckes and Reconstruction #9

Juckes has archived 64 reconstruction variations in the file mitrie_new_reconstructions_v01.csv (mirrored in mitrie_new_reconstructions_v01.nc). The 9th platter in the jukebox is mr_mbh_1000_cvm_nht_01.02.001_pc – which is some kind of composite-variance-match version of MBH (whle he has 1 CVM version each for Esper, Hegerl, Jones and Moberg, he has no fewer than 7 different versions for MBH and […]

In the Team Euro Moberg composite, Team Euro has constructed […]

CVM (take the average of scaled proxies and re-scale the average to match the instrumental record) seems to me to be a less dangerous […]

Subsequently new cores were dated to the 11th century by Schweingruber, resulting in […]
