Recent summer warming in northwestern Canada exceeds the Holocene thermal maximum

age model based on volcanic horizons and counting of annual layers (seasonal variations of stable isotopes)

; archiveType changed - was originally Ice core (IC)

The reference has been changed : Cole-Dai was not the isotope record, it's Moseley-Thompson. Added secondary reference of Masson 2000

Precipitation weighted signal subject to post-depositional processes
