I have been experimenting with different ways to visualise triangulated global temperature data in 3D. Here are the monthly anomaly values for the last 20 years. Of course you can only see one side of the earth at a time, so I also slowly rotate it. The monthly variability is much more striking than a slow overall warming trend.
The temperature colour scale used in all animations is this one.
This is the latest data for March 2017 showing explicitly the spherical triangulation. The underlying data I use is GHCN V3 station data normalised to 1961-1990 combined with HSST3 ocean data.
There is also a youtube video of 137 years starting in 1880. The distorted earth shape in early years is caused by poor sampling.
