We analyze the global variations in the timing and magnitude of the Holocene Thermal
Maximum (HTM) and their dependence on various forcings in transient simulations covering …

To improve our understanding of the mechanism behind the 8.2 kaBP cooling event, we
compare proxy evidence with climate model simulations in which the thermohaline ocean …

A comprehensive database of paleoclimate records is needed to place recent warming into
the longer-term context of natural climate variability. We present a global compilation of …

To understand how planet Earth works we study it increasingly as a system–a collection of
interdependent parts or spheres–the lithosphere, the hydrosphere, the cryosphere, the …

The disintegration of ice shelves, reduced sea-ice and glacier extent, and shifting ecological
zones observed around Antarctica, highlight the impact of recent atmospheric and oceanic …

The Antarctic Peninsula is one of the three fastest warming regions on Earth. Here we
review Holocene proxy records of marine and terrestrial palaeoclimate in the region, and …

We report on the existence and nature of Holocene solar and climatic variations on
centennial to millennial timescales. We introduce a new solar activity proxy, based on nitrate …

The causes of the recent increase in Antarctic sea ice extent, characterised by large regional
contrasts and decadal variations, remain unclear. In the Ross Sea, where such a sea ice …

A strong mid-Holocene transition has been identified by wavelet analyses in several sea ice
cover records from the circum-Antarctic area, ice core records (Taylor dome, Byrd) and …

Variability on centennial to multi-centennial timescales is mentioned as a feature in
reconstructions of the Holocene climate. As more long transient model simulations with …
