Do climate scientists have a sense of humour?  In the case of James  Hansen, head of the Goddard Institute for Space Science (GISS) at NASA, and perhaps the world’s best known climate researcher, the answer appears to be yes.

Hansen’s team regularly publish global maps of temperature changes, and in the most recent the warming in the Arctic was sufficient to run off the existing colour-graded scale. Needing to add a tone, their choice of colour was hot pink.
