Underestimation of the Tambora effects in North American taiga ecosystems
International audience The Tambora eruption (1815 AD) was one of the major eruptions of the last two millennia and has noequivalents over the last two centuries. Here, we collected an extensive network of earlymeteorological time series, climate simulation data and numerous, well-replicated proxy re...
