Some beautiful photos on display at Proud Chelsea at the moment - Ragnar Axelsson's Last Days of the Arctic. These don't do the exhibition justice - I recomend it if you are nearby. While I am genuinely upset by the site of dead Narwhals in kayaks, I am nevertheless endlessly in love with the people of the Arctic.
(couple of cheeky instagrams I took)
Betweeen this and the book I'm reading at the moment (Sarah Wheeler's 'Terra Incognita' since you asked) I have have started 2012 with a strange feeling which I think is generally described as 'wanderlust'.
