Evidence for extreme floods in arid subtropical northwest Australia during the Little Ice Age chronozone (CE 1400-1850) by Rouillard, A., Skrzypek, G., Turney, C., Dogramaci, S., Hua, Q., Zawadzki, A., Reeves, J., Greenwood, Paul, O'Donnell, A., Grierson, P.

“…The occurrence of extreme floods during this period, which encompasses the Little Ice Age (LIA; CE 1400-1850), is coherent with other southern tropical datasets along the ITCZ over the last 2000 years, suggesting synchronous hydroclimatic changes across the region. …”

Episodic Neoglacial snowline descent and glacier expansion on Svalbard reconstructed from the 14C ages of ice-entombed plants by Miller, Gifford, Landvik, J., Lehman, S., Southon, J.

“…The response of the Northern Hemisphere cryosphere to the monotonic decline in summer insolation and variable radiative forcing during the Holocene has been one of irregular expansion culminating in the Little Ice Age, when most glaciers attained their maximum late Holocene dimensions. …”

Madagascar corals track sea surface temperature variability in the Agulhas Current core region over the past 334 years by Zinke, Jens, Loveday, B., Reason, C., Dullo, W., Kroon, D.

“…AC SSTs variabilities show distinct cooling through the Little Ice Age and warming during the late 18(th), 19th and 20th century, with significant decadal variability superimposed. …”

A reconstruction of extratropical Indo-Pacific sea-level pressure patterns during the Medieval Climate Anomaly by Goodwin, I., Browning, S., Lorrey, A., Mayewski, P., Phipps, S., Bertler, N., Edwards, Peter, Cohen, T., Van Ommen, T., Curran, M., Barr, C., Stager, J.

“…Subtropical and extratropical proxy records of wind field, sea level pressure (SLP), temperature and hydrological anomalies from South Africa, Australia/New Zealand, Patagonian South America and Antarctica were used to reconstruct the Indo-Pacific extratropical southern hemisphere sea-level pressure anomaly (SLPa) fields for the Medieval Climate Anomaly (MCA ~700–1350 CE) and transition to the Little Ice Age (LIA 1350–1450 CE). The multivariate array of proxy data were simultaneously evaluated against global climate model output in order to identify climate state analogues that are most consistent with the majority of proxy data. …”

Synchronizing Holocene lacustrine and marine sediment recordsusing paleomagnetic secular variation by Olafsdottir, S., Geirsdottir, A., Miller, Gifford, Stoner, J., Channell, J.

“…Low and regular accumulation rates during the Holocene thermal maximum suggest regionally stable, vegetated catchments, followed by a stepped landscape destabilization during the transition into neoglaciation, culminating with maximum sedimentation rates during the Little Ice Age. PSV allows synchronization between multiple records from nearby marine and lacustrine archives, providing improved age models and a means of assessing leads and lags between marine and terrestrial environments.…”

Neoglacial climate anomalies and the Harappan metamorphosis by Giosan, L., Orsi, W., Coolen, Marco, Wuchter, C., Dunlea, A., Thirumalai, K., Munoz, S., Clift, P., Donnelly, J., Galy, V., Fuller, D.

“…Superimposed on this trend, anomalies such as the Little Ice Age point to asymmetric changes in the extratropics of either hemisphere. …”

Regional Holocene climate and landscape changes recorded in the large subarctic lake Torneträsk, N Fennoscandia by Meyer-Jacob, Carsten, Bindler, Richard, Bigler, Christian, Leng, Melanie J., Lowick, Sally E., Vogel, Hendrik

“…Our results show three periods of regional landscape alteration with distinct change in sediment composition: i) landscape development following deglaciation and through the Holocene Thermal Maximum, ~ 9500–3400 cal yr BP; ii) increased soil erosion during the Little Ice Age (LIA); and iii) rapid change during the past century coincident with ongoing climate change. …”

Using in situ cosmogenic 10Be, 14C, and 26Al to decipher the history of polythermal ice sheets on Baffin Island, Arctic Canada by Briner, J., Lifton, N., Miller, Gifford, Refsnider, K., Anderson, R., Finkel, R.

“…These samples require shielding by ice for a significant portion of the Holocene, and more burial than during the Little Ice Age alone. Simple exposure-burial modeling suggests that 2400–2900 yr of total ice cover during Neoglaciation is required to explain measured in situ14C inventories. …”

The Holocene history of the North American Monsoon: 'known knowns' and 'known unknowns' in understanding its spatial and temporal complexity by Metcalfe, Sarah E., Barron, J.A., Davies, S.J.

“…Proxy data from southern Mexico, Central America and the Caribbean reveal generally wetter conditions, whereas records from the highlands of central Mexico and much of the Yucatan are typified by long -term drought. The Little Ice Age (LIA), in the north, was characterised by cooler, wetter winter conditions that have been linked with increased frequency of El Niño’s. …”

The Ross Sea Dipole-temperature, snow accumulation and sea ice variability in the Ross Sea region, Antarctica, over the past 2700 years by Bertler, N., Conway, H., Dahl-Jensen, D., Emanuelsson, D., Winstrup, M., Vallelonga, P., Lee, J., Brook, E., Severinghaus, J., Fudge, T., Keller, E., Troy Baisden, W., Hindmarsh, R., Neff, P., Blunier, T., Edwards, Peter, Mayewski, P., Kipfstuhl, S., Buizert, C., Canessa, S., Dadic, R., Kjær, H., Kurbatov, A., Zhang, D., Waddington, E., Baccolo, G., Beers, T., Brightley, H., Carter, L., Clemens-Sewall, D., Ciobanu, V., Delmonte, B., Eling, L., Ellis, A., Ganesh, S., Golledge, N., Haines, S., Handley, M., Hawley, R., Hogan, C., Johnson, K., Korotkikh, E., Lowry, D., Mandeno, D., McKay, R., Menking, J., Naish, T., Noerling, C., Ollive, A., Orsi, A., Proemse, B., Pyne, A., Pyne, R., Renwick, J., Scherer, R., Semper, S., Simonsen, M., Sneed, S., Steig, E., Tuohy, A., Ulayottil Venugopal, A., Valero-Delgado, F., Venkatesh, J., Wang, F., Wang, S., Winski, D., Holly, W., Whiteford, A., Xiao, C., Yang, J., Zhang, X.

“…Notably, during the Little Ice Age, West Antarctica and the western Ross Sea experienced colder than average temperatures, while the eastern Ross Sea underwent a period of warming or increased isotopic enrichment. …”
