You *could* blame it on the assumption that all sea going vessels
simultaneously switched from bucket measurement to water intake
measurement; a false assumption which biases the record.

You *could* blame it on the XBT devices which have been proven to have
a warm bias, see Gouretski et al. 2006, obviously biasing the record.

Or you could just ignore any quality control issues with the data and
scream about the falling sky because the point suits you.

If you have better data, you are certainly welcome
to post them here. Until then, science sides with
data over conjecture.
