Mediterranean climate variability during the Holocene

Climate Forcing during the Holocene

The role of several important factors that have played a role in Holocene climate change is examined. These forcing factors operate on different time-scales: lower frequency (millennial-scale) climate changes associated with orbital forcing, century-scale variability associated with solar forcing, and annualto decadal-scale variability associated with volcanic forcing. Feedbacks within the clim...

General Circulation Modelling of Holocene climate variability

Results from a series of Goddard Institute for Space Studies (GISS) General Circulation Models (GCMs) are used to assess climate variability in the pre-anthropogenic Holocene, the interval following the end of the last glacial beginning roughly 11.5 kyr BP. In particular, we focus on the forced aspects of this variability. The principle forcings are orbital, solar, volcanic and events (such as ...

Climate-Human interaction over the Iranian Plateau during the Upper Pleistocene-Holocene: A review

During the past two decades an array of studies have shed light on potential links between the evolution of Hominids as well as Human dispersal out of Africa and episodes of abrupt climate change. Although archaeological evidences suggest that anatomically modified humans appeared in Africa between 200 and 150 ky ago, the timing of the early humans migration out of Africa remained unclear. Stra...

Quantifying Regional Vegetation Cover Variability in North China during the Holocene: Implications for Climate Feedback

Validating model simulations of vegetation-climate feedback needs information not only on changes in past vegetation types as reconstructed by palynologists, but also on other proxies such as vegetation cover. We present here a quantitative regional vegetation cover reconstruction for North China during the Holocene. The reconstruction was based on 15 high-quality lake sediment profiles selecte...
