Arctic climate change: observed and modelled temperature and sea-ice variability
Changes apparent in the arctic climate system in recent years require evaluation in a century-scale perspective in order to assess the Arctic's response to increasing anthropogenic greenhouse-gas forcing. Here, a new set of century- and multidecadal-scale observational data of surface air temperature (SAT) and sea ice is used in combination with ECHAM4 and HadCM3 coupled atmosphere-ice-ocean global model simulations in order to better determine and understand arctic climate variability. We show that two pronounced twentieth-century warming events, both amplified in the Arctic, were linked to sea-ice variability. SAT observations and model simulations indicate that the nature of the arctic warming in the last two decades is distinct from the early twentieth-century warm period. It is suggested strongly that the earlier warming was natural internal climate-system variability, whereas the recent SAT changes are a response to anthropogenic forcing. The area of arctic sea ice is furthermore observed to have decreased similar to8 x 10(5) km(2) (7.4%) in the past quarter century, with record-low summer ice coverage in September 2002. A set of model predictions is used to quantify changes in the ice cover through the twenty-first century, with greater reductions expected in summer than winter. In summer, a predominantly sea-ice-free Arctic is predicted for the end of this century
British III done: recent work on Shakespeare and British, English, Irish, Scottish and Welsh identities
This contribution to <i>Literature Compass</i> has a three-fold purpose. First, it aims to do what it says in the title, and flag up recent approaches to British identities in Shakespeare studies. Secondly, it seeks to remind readers of an earlier and now largely forgotten tradition of nationalist criticism and scholarship preoccupied with the place of Britain – nation, state and empire – that flourished in the 1920s and 1930s. Thirdly, it endeavours to excavate some of the more obscure material on the subject that, because of its place of publication, may have been overlooked. The material collected here covers issues of borders, colonialism, culture, genre, identity, invasion, language, mapping, monarchy, plantation, union, and the matter of Britain, especially in the histories, though as will be seen this work encompasses most of Shakespeare's corpus. The short introductions to each section and the accompanying bibliography of over 300 items, ranging from notes and queries to substantial essays, is divided into six sections, beginning with a brief overview of the historical debate, then focusing on criticism dealing broadly with Britain, then embracing material ordered by constituent nation: England, Ireland, Scotland and Wales. That there is an even spread of material under this handful of headings suggests that each and every nation within this multi-nation state, as well as the problematic and often contested whole, has attracted its fair share of critical concern
