NASA GISS has a great web application that let’s users generate maps of global monthly temperature anomalies in 2 degree grids. I’ve made a 27 second video of 7 decade maps for July to see how global temperature anomalies have progressed through my life so far.
Here’s the link to NASA GISS’s map application page. It’s very easy to use.
My video shows 7 maps, each showing the July average for each of the 16,200 grid cells (2×2 lat/lon).
