UC Berkeley scientists calculated average ocean temperatures from 1999 to 2015, separately using ocean buoys and satellite data, and confirmed the uninterrupted warming trend reported by NOAA in 2015, based on that organization's recalibration of
sea surface temperature recordings from ships and buoys.
Recent research highlights include new
sea surface temperature records for the Paleogene and biomarker records for methane cycling and hydrological changes during past episodes of global warmth.
Therefore she analyzed her Galápagos coral temperature chronologies alongside published coral temperature chronologies from islands farther north and west and
instrumental sea surface temperature records from the southern Galápagos town of Puerto Ayora and the Peruvian coastal town of Puerto Chicama.
This means the new NOAA record is likely the most
accurate sea surface temperature record in recent years, the authors say on a site presenting their study, hosted by author Kevin Cowtan and the University of York.
And by the way, I wasn't asking about anything Dr. Curry wrote, I was asking about your assertion as supposed fact that the broad uncertainty in
historic sea surface temperature records can be so drastically improved.
Because the GISS analysis combines
available sea surface temperature records with meteorological station measurements, we test alternative choices for the ocean data, showing that global temperature change is sensitive to estimated temperature change in polar regions where observations are limited.
The U.K. Meteorological Office Hadley Centre's
sea surface temperature records HadSST2 and hadSST3 are based on data from the ICOADS project which claims «ICOADS is probably the most complete and heterogeneous collection of surface marine data in existence.»
So, she analyzed her Galápagos coral temperature chronologies alongside published coral temperature chronologies from islands farther north and west and
instrumental sea surface temperature records from the southern Galápagos town of Puerto Ayora and the Peruvian coastal town of Puerto Chicama.
Only
the sea surface temperature record shows the large spike.
Indeed, many of the groups using weather station records for estimating global temperature trends, also combine their estimates with
the sea surface temperature records to construct «land - and - sea» global temperature estimates.
We argue that the abrupt temperature drop of ~ 0.3 °C in 1945 is the apparent result of uncorrected instrumental biases in
the sea surface temperature record [since it is only apparent in SSTs].
In case you thought something interesting was happening to
sea surface temperature records - it isn't @CarbonBrief.
The Kommersant talks about HaCRUT data in connection with land stations, but «HadCRUT is the dataset of monthly temperature records formed by combining
the sea surface temperature records compiled by the Hadley Centre of the UK Met Office and the land surface temperature records compiled by the Climatic Research Unit (CRU) of the University of East Anglia.
We argue that the abrupt temperature drop of 0.3 C in 1945 is the apparent result of uncorrected instrumental biases in
the sea surface temperature record.

The most important result of our work may therefore be to identify places where extra attention should be given to addressing problems in the existing
sea surface temperature records.
