THE IMPACT OF THE 8,200 CAL BP CLIMATIC EVENT ON HUMAN MOBILITY STRATEGIES DURING THE IBERIAN LATE MESOLITHIC
Recent marine and lake core studies in the Western Mediterranean Basin and Iberia have changed the traditional perception of Holocene climate change. Particularly important in this region, the 8,200Expand
The Younger Dryas impact hypothesis: a critical review
Abstract The Younger Dryas impact hypothesis suggests that multiple extraterrestrial airbursts or impacts resulted in the Younger Dryas cooling, extensive wildfires, megafaunal extinctions andExpand
Milestones in the evolution of the atmosphere with reference to climate change
The history of life on Earth is critically dependent on the carbon, sulfur and oxygen cycles of the lithosphere – hydrosphere – atmosphere – biosphere system. An Archean oxygen-poor greenhouseExpand
Do Extraordinary Claims Require Extraordinary Evidence?
TLDR
The misuse of ECREE to suppress innovation and maintain orthodoxy should be avoided as it must inevitably retard the scientific goal of establishing reliable knowledge. Expand

Was the Younger Dryas Triggered by a Flood?
Draining of a huge lake into the Northern Atlantic may have triggered a cold period ~12,900 years ago. The route taken by the flood waters remains unknown.
