You don't have the qualifications to interpret the data. You don't understand how it was calculated, nor do you understand the assumptions made in collecting and interpreting the data before it was converted into a graphical format. I suspect that you don't even know what 'anomaly' means in this context.
I can produce similar graphs from sources no less 'reputable' than NASA that, when subjected to your simplistic assessment, would demonstrate the exact opposite of your statement.
Here's one now :
