Here is a full animation of all Hadcrut4.3 monthly spatial anomaly data. In the early years you can see individual ship voyages! Note the strong variations throughout, especially in northern continents during winter months, and try to spot the El Niño events.

The video uses my new colour table which I think is better than the Met Office scheme. Blue is for DT < 0 and red for DT> 0. The table is made using a linear interpolation over a ± 10 degree range. Anything just below zero looks slightly cool and anything above zero looks slightly warm. For example this is the plot for October 2015 using the new colour scheme.

In my opinion this better reflects the overall warming pattern last month, compared to the Met Office plot which exaggerates it.
