Andy Russell has posted an interesting graph in an attempt to provide support for the notion that things are still warming up, despite the cold we are experiencing in the UK at the moment.
The GISS derived figure shows a view of Arctic temperature anomalies, with the pole apparently experiencing temperatures 4-7° (not sure if this is F or C) above normal.
The problem with this is that there is almost no data to support this, as Stephen Goddard has previously shown. (GISS fill in with model-derived numbers, upon which nobody should surely place any reliance.) I've constructed a composite of Andy's GISS chart and Goddard's figure showing which gridcells have real data to support them.
