Is it possible to know something? About the global temperature data?

In the comments section on WUWT there is this graph, showing anomalies for Tmax and Tmin, globally, since 1940.

Is it possible to confirm this information?  And what would it mean?

The questions I ask are as follows.

Is the graph real?  Can it be reproduced by anyone?

What data is used?

If those are satisfied, so that it actually represents a data analysis, what does it mean?
