Seasonally resolved stratigraphy at Jwalapuram India shows regional surface warming after the Toba volcanic super-eruption.

ABSTRACT: Understanding the nature and tempo of global environmental responses to the ∼74,000 BP (∼74 ka) Toba volcanic super-eruption is based primarily on historical analogies and climate models that lack ground-truthing in regions distal to eruptions. Here, we report the first proxy-based terrestrial record of the immediate environmental impact of the Younger Toba Tuff (YTT) eruption on the hominin-occupied ecosystem in peninsular India, spanning six annual monsoonal cycles directly following the YTT event. We present a multiproxy paleoclimate dataset from Jwalapuram in southern India, featuring a geochemical characterization of multiple YTT tephra and hardpan layers, complemented by detailed stratigraphic observations, sedimentological insights, and stable carbon isotope data. Taken together, th
