Abstract This paper explores the possible links between rapid climate change (RCC) and social change in the Near East and surrounding regions (Anatolia, central Syria, southern Israel, Mesopotamia, Cyprus and eastern and central Sahara) during the ''long'' 4th millennium (∼4500–3000) BC. Twenty terrestrial and 20 marine climate proxies are used to identify long-term trends in humidity ...

2015-9-15 · 1. Introduction1.1. A mid-Holocene climatic transition. The occurrence of a substantial transition in the global climate system during the period 6–5 ka is widely acknowledged (Steig, 1999, Mayewski et al., 2004, Wanner et al., 2008, Brooks, 2012).This transition marked the termination of the Holocene thermal maximum (HTM), a relatively warm period with temperatures markedly higher than ...
2019-1-8 · Calcium signaling are conserved from invertebrates to vertebrates and plays critical roles in many molecular mechanisms of embryogenesis and postnatal development. As a critical component of the signaling pathway, the RyR medicated calcium-induced calcium release signaling system, has been well studied along with their regulator FK506-binding protein 12 (FKBP12/Calstabin).
2006-5-20 · Anthropogenic climate change will continue long after anthropogenic CO2 emissions cease. Atmospheric CO2, global warming and ocean circulation will approach equilibrium on the millennial timescale, whereas thermal expansion of the ocean, ice sheet melt and their contributions to sea level rise are unlikely to be complete. Atmospheric CO2 in year 3000 depends non-linearly on the total amount of ...
