Has the AMO peaked?

Has the Atlantic Multidecadal Oscillation peaked?

This timing would be reasonable given that it was at the lowest part of its cycle around 1974. Here is the graph of EOT2 (in degrees Celsius) along with its correlation image:

  1. Is there no older data?

    30 years isn't much for a climate model.
