TLDR
In this article, the authors present a high-resolution 10Be chronology of glacier fluctuations in New Zealand's Southern Alps over the past 7000 years, including at least five events during the last millennium.Abstract:
Understanding the timings of interhemispheric climate changes during the Holocene, along with their causes, remains a major problem of climate science. Here, we present a high-resolution 10Be chronology of glacier fluctuations in New Zealand’s Southern Alps over the past 7000 years, including at least five events during the last millennium. The extents of glacier advances decreased from the middle to the late Holocene, in contrast with the Northern Hemisphere pattern. Several glacier advances occurred in New Zealand during classic northern warm periods. These findings point to the importance of regional driving and/or amplifying mechanisms. We suggest that atmospheric circulation changes in the southwest Pacific were one important factor in forcing high-frequency Holocene glacier fluctuations in New Zealand.read more

Too young or too old: Evaluating cosmogenic exposure dating based on an analysis of compiled boulder exposure ages
TL;DR: Cosmogenic exposure dating has greatly enhanced our ability to define glacial chronologies spanning several global cold periods, and glacial boulder exposure ages are now routinely used to constrain glaciers.

TL;DR: A global overview of glacier advances and retreats (grouped by regions and by millennia) for the Holocene is compiled from previous studies as mentioned in this paper, which reconstructs of glacier fluctuations are based on mapping and dating moraines defined by 14 C, TCN, OSL, lichenometry and tree rings (discontinuous records/time series).

Contributions and unrealized potential contributions of cosmogenic-nuclide exposure dating to glacier chronology, 1990–2010
TL;DR: In this paper, the application of cosmogenic-nuclide exposure dating to date glacial deposits is reviewed, and some strategies for realizing this potential are suggested for utilizing the large data set of exposure-dated glacier chronologies to better understand global and regional climate dynamics during Lateglacial and Holocene millennialscale climate changes.

TL;DR: A solar forcing mechanism therefore may underlie at least the Holocene segment of the North Atlantic's “1500-year” cycle, potentially providing an additional mechanism for amplifying the solar signals and transmitting them globally.

TL;DR: A seasonally resolved record of titanium shows that the collapse of Mayan civilization in the Terminal Classic Period occurred during an extended regional dry period, punctuated by more intense multi-year droughts centered at approximately 810, 860, and 910 A.D as mentioned in this paper.
