Differences are wrt IPCC "pre-industrial" era. [This period is better
described as the Early Industrial Era and probably underestimates the
true anomaly over the Pre-Industrial Era by about 0.2C]

If the temperatures mentioned above are referred to those of the Roman
Warm Period or the Medieval Warm Period rather than to those of the
Little Ice Age (also known as the Pre-Industrial Era), they would be
negative rather than positive.

It's interesting also to note that the figures given above are in line
with the excess temperatures of the Urban Heat Island effect, first
measured in the early 1800s at 2.0 degF.
