The island and the world: kinship, friendship and living together in selected writings of Sam Selvon

This article argues that the ethical force of Trinidadian Sam Selvon’s creative writings comes from the particular configuration of living together that he is interested in, both in his Trinidadian novels and his London ones. It reads examples of this living together alongside and in difference that emerges through his focus on the relations between neighbours, friends and lovers, rather than the kinship relations of family. It argues that his works thereby map horizontal zones of attachment and possible solidarities across groupings that reconfigure vertically inscribed genealogical paradigms of belonging to place and each other based on models of historical continuity and inheritance.

Fast and slow responses of Southern Ocean sea surface temperature to SAM in coupled climate models

We investigate how sea surface temperatures (SSTs) around Antarctica respond to the Southern An- nular Mode (SAM) on multiple timescales. To that end we examine the relationship between SAM and SST within unperturbed preindustrial control simulations of coupled general circulation models (GCMs) included in the Climate Modeling Intercomparison Project phase 5 (CMIP5). We develop a technique to extract the re- sponse of the Southern Ocean SST (55◦S−70◦S) to a hypothetical step increase in the SAM index. We demonstrate that in many GCMs, the expected SST step re- sponse function is nonmonotonic in time. Following a shift to a positive SAM anomaly, an initial cooling regime can transition into surface warming around Antarctica. However, there are large differences across the CMIP5 ensemble. In some models the step response function never changes sign and cooling persists, while in other GCMs the SST anomaly crosses over from negative to positive values only three years after a step increase in the SAM. This intermodel diversity can be related to differences in the models’ climatological thermal ocean stratification in the region of seasonal sea ice around Antarctica. Exploiting this relationship, we use obser- vational data for the time-mean meridional and vertical temperature gradients to constrain the real Southern Ocean response to SAM on fast and slow timescales.
