The IntCal20 Northern Hemisphere radiocarbon age calibration curve (0-55 kcal BP) by Reimer, PJ, Austin, WEN, Bard, E, Ramsey, C

Multi-decadal variations in southern hemisphere atmospheric 14C: evidence against a Southern Ocean sink at the end of the Little Ice Age CO2 anomaly by Turney, C, Palmer, J, Hogg, A, Fogwill, C, Jones, R, Ramsey, C, Fenwick, P, Grierson, P, Wilmshurst, J, O'Donnell, A, Thomas, Z, Lipson, M

“…<p>Northern Hemisphere-wide cooling during the Little Ice Age (LIA; 1650–1775 Common Era, C.E.) was associated with a ~5 ppmv decrease in atmospheric carbon dioxide. …”

Fluctuating radiocarbon offsets observed in the southern Levant and implications for archaeological chronology debates by Manning, S, Griggs, C, Lorentzen, B, Ramsey, C, Chivall, D, Jull, A, Lange, T

“…Considerable work has gone into developing high-precision radiocarbon (14C) chronologies for the southern Levant region during the Late Bronze to Iron Age/early Biblical periods (~1200-600 BC), but there has been little consideration whether the current standard Northern Hemisphere 14C calibration curve (IntCal13) is appropriate for this region. …”

Global peak in atmospheric radiocarbon provides a potential definition for the onset of the anthropocene epoch in 1965 by Turney, C, Palmer, J, Maslin, M, Hogg, A, Fogwill, C, Southon, J, Fenwick, P, Helle, G, Wilmshurst, J, McGlone, M, Ramsey, C, Thomas, Z, Lipson, M, Beaven, B, Jones, R, Andrews, O, Hua, Q

“…Here we report a series of precisely-dated tree-ring records from Campbell Island (Southern Ocean) that capture peak atmospheric radiocarbon (14C) resulting from Northern Hemisphere-dominated thermonuclear bomb tests during the 1950s and 1960s. …”

Punctuated shutdown of Atlantic Meridional Overturning Circulation during Greenland Stadial 1 by Hogg, A, Ramsey, C, Staff, R, Southon, J, Turney, C, Palmer, J, Fenwick, P, Boswijk, G, Friedrich, M, Helle, G, Hughen, K, Jones, R, Kromer, B, Noronha, A, Reynard, L, Wacker, L

“…By precisely aligning Southern and Northern Hemisphere tree-ring 14C records with marine 14C sequences we document two relatively short periods of AMOC collapse during the stadial, at ~12,920-12,640 cal BP and 12,050-11,900 cal BP. …”

Decadally resolved lateglacial radiocarbon evidence from New Zealand Kauri by Hogg, A, Southon, J, Turney, C, Palmer, J, Ramsey, C, Fenwick, P, Boswijk, G, Büntgen, U, Friedrich, M, Helle, G, Hughen, K, Jones, R, Kromer, B, Noronha, A, Reinig, F, Reynard, L, Staff, R, Wacker, L

“…Two floating kauri 14C time series, curve-matched to IntCal13, serve as a radiocarbon backbone through the Younger Dryas. The floating Northern Hemisphere (NH) 14C datasets derived from the YD-B and Central European Lateglacial Master tree-ring series are matched against the new kauri data, forming a robust NH 14C time series to ~14,200 cal BP. …”

Evidence for a bi-partition of the Younger Dryas Stadial in East Asia associated with inversed climate characteristics compared to Europe by Schlolaut, G, Brauer, A, Nakagawa, T, Lamb, H, Tyler, J, Staff, R, Marshall, M, Ramsey, C, Bryant, C, Tarasov, P

“…The Younger Dryas Stadial (YDS) was an episode of northern hemispheric cooling which occurred within the Last Glacial Interglacial Transition (LGIT). …”
