Jha, Gopesh; Costa, Mafalda; Tsoupra, Anna; Barrocas Dias, Cristina; Kwiecien, Ola; Longman, Jack; Breitenbach, Sebastian F. M.; Ditchfield, PeterUnderstanding 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 homininoccupied ecosystem i...
A stalagmite test of North Atlantic SST and Iberian hydroclimate linkages over ...
Denniston, Rhawn F.; Houts, Amanda N.; Asmerom, Yemane; Wanamaker Jr., Alan D.; Haws, Jonathan; Polyak, Victor J.; Thatcher, Diana L.Close coupling of Iberian hydroclimate and North Atlantic sea surface temperature (SST) during recent glacial periods has been identified through the analysis of marine sediment and pollen grains co-deposited on the Portuguese continental margin. While offering precisely correlatable records, these time series have lacked a directly dated, site-specific record of continental Iberian climate spanning multiple gl...
