TLDR
In this article, the major ion series developed from new subannual scale sampling of an ice core from central Greenland are calibrated with instrumental series of atmospheric sea-level pressure recording major marine (Icelandic Low) and terrestrial (Siberian High) atmospheric circulation systems to provide proxy records of atmospheric circulation over the past 1400 years.Abstract:
Major ion series developed from new subannual scale sampling of an ice core from central Greenland are calibrated with instrumental series of atmospheric sea-level pressure recording major marine (Icelandic Low) and terrestrial (Siberian High) atmospheric circulation systems to provide proxy records of atmospheric circulation over the past 1400 years. Examination of the proxy records reveals: major changes in behaviour of these systems c. ad 1400, multidecadal- and centennial-scale periodic components, characterization of mean sea-level pressure anomaly fields during the ‘Little Ice Age’ and the ‘Mediaeval Warm Period’, the potential role of solar forcing, coupled ocean-atmosphere associations, and a perspective within which the characteristics of instrumental-era climate can be assessed.read more

TL;DR: In this paper, an examination of similar to50 globally distributed paleoclimate records reveals as many as six periods of significant rapid climate change during the time periods 9000-8000, 6000-5000, 4200-3800, 3500-2500, 1200-1000, and 600-150 cal yr B.P.

Climate over past millennia
Philip Jones,Michael E. Mann +1 more
TL;DR: This paper reviewed evidence for climate change over the past several millennia from instrumental and high-resolution climate "proxy" data sources and climate modeling studies and concluded that late 20th century warmth is unprecedented at hemispheric and, likely, global scales.

TL;DR: The Southern Hemisphere climate system varies on timescales from orbital, through millennial to sub-annual, and is closely coupled to other parts of the global climate system as discussed by the authors.

TL;DR: In this paper, the authors present observational estimates of desert dust based on pa- leodata proxies showing a doubling of the amount of dust during the 20th century over much, but not all the globe.

TL;DR: A review of the state of the Antarctic and Southern Ocean climate, and its relation to the global climate system over the last few millennia can be found in this paper, where a network of recently available shallow firn cores, and to that of the past 50 years, which was monitored by the continuous instrumental record.
