Dingbatt: Surely the sub heading is wrong? Shouldn’t it be 1880-2015?
No - I don't think so.
It seems to be standard to use a point of reference where the temperature averages are known to be very accurate - the further you go back the more questionable they probably are, but the individual annual records are displayed in that case as "below average".
Similarly, from the Earth.nullschool.net project:
ocean surface temperatures and anomaly from daily average (1981-2011) updated daily
The sea surface temperature anomaly today showing most of our region 1-4 deg C above that 30 year average.
If it was possible to show 100 year average, then the pile of crap we're in might probably look even more dire.
