Stable isotopes and element concentrations of samples from the Wadi Bih, United Arab Emirates

Ocean acidification triggered by Siberian Trap volcanism was a possible kill mechanism for the Permo-Triassic Boundary mass extinction, but direct evidence for an acidification event is lacking. We present a high-resolution seawater pH record across this interval, using boron isotope data combined with a quantitative modeling approach. In the latest Permian, increased ocean alkalinity primed the Earth system with a low level of atmospheric CO2 and a high ocean buffering capacity. The first phase of extinction was coincident with a slow injection of carbon into the atmosphere, and ocean pH remained stable. During the second extinction pulse, however, a rapid and large injection of carbon caused an abrupt acidification event that drove the preferential loss of heavily calcified marine biota.

Trajectories and outcomes of the 'Arab Spring' : comparing Tunisia, Egypt, Libya and Syria

Almost three years have passed since the 'Arab Spring' began in late 2010. In the major sites of popular uprisings, political conditions remain unsettled or violent. Despite similarities in their original opposition to authoritarian rule, the outcomes differed from country to country. In Tunisia and Egypt, processes of transiting from authoritarian rule produced contrasting consequences for democratic politics. Uprisings led to armed rebellion in Libya and Syria, but whereas Gaddafi was overthrown, Asad was not. What explains the different trajectories and outcomes of the Arab Spring? How were these shaped by the power structure and levels of social control of the pre-uprising regimes and their state institutions, on the one hand, and by the character of the societies and oppositional forces that rose against them? Comparing Tunisia with Egypt, and Libya with Syria, this paper discusses various factors that account for variations in the trajectories and outcomes of the Arab Spring, namely, the legacy of the previous regime, institutional and constitutional choices during "transition" from authoritarian rule, socioeconomic conditions, and the presence of absence of ethnic, sectarian and geographic diversity.
