► Widespread aridity developed from around 4600 yrs BP in the E Mediterranean.► Data do not support a rapid climate event around 4200 yrs BP in the E Mediterranean.
Examines how volcanoes work and how they affect the environment, life, and human societies.Emphasizes the dynamic nature of the earth's tectonic system and its relationship to physical features, volcanism, earthquakes, minerals and rocks and geologic structures. View course details in My Plan: ESS 101 ESS 102 Space and Space Travel (5) I&S/NWExplores the sun, solar storms, observations from space and from Earth; Earth's space environment, radiation belts and hazards, plasma storms and auroras, rockets and propulsion, human exploration efforts, societal impact, planetary systems and resources, and project highlighting space and its exploration. Focuses on topics of particular interest in gemology, such as mechanisms of color, history and lore of gems, and uses of gems.The course emphasizes the intrinsic relationship between human societies and geologic processes, hazards and resources. Hands-on laboratories using about one hundred representative gems and minerals.This is followed by a less wet period leading up to one of fully-developed aridity from c. There is a need for more high-resolution paleoclimate records, in order to (i) better understand regional patterns and trends versus local climate variability and to (ii) fill the gap of data from some regions, such as the Near East, Greece and Egypt.Further, we evaluate the regional occurrence of a proposed widespread climate event at 4200 yrs BP.The eastern Mediterranean, with its long archaeological and historical records, provides a unique opportunity to study human responses to climate variability.
We review paleoclimate data and reconstructions from the region with a focus on the last 6000 years.

What fossils tell us about past life and environments.
As the chronicle of plate motions through time, paleogeography is fundamental to our understanding of plate tectonics and its role in shaping the geology of the present-day.
To properly appreciate the history of tectonics—and its influence on the deep Earth and climate—it is imperative to seek an accurate and global model of paleogeography.
► Our review highlights the need to improve paleoclimate reconstructions in the region.
