I mean global warming caused by the use of fossil fuels.
Specifically, the questioning comes on the heels of observing some old sea level change (SLC) records (On The Evolution of Sea Level Change).
The use of records made long ago is becoming a popular endeavor for some situations (Citizen-Science, old whaling ship records of Arctic Ice).

The graph at Fig. 2 presents those records kept as ordered, and Fig. 1 is tide gauge station records of Stockholm, from the PSMSL. database.
The graph (Fig. 1) is presented in the new Dredd Blog SLC fingerprint format which does the arithmetic for you (SLC Fingerprints R Us - 2).
Other formats of old records, such as photos, are being studied for additional insight (Aerials Records of Greenland circa 1900).
These records suggest that there was much more ice on Greenland way back then, and that it has been melting for a long time.
The indication is that the Industrial Revolution of 1750 began to have an impact on the oceans earlier than previously thought.
The concept many hold today is that thermal expansion was the only game in town that caused SLC way back then.
To the contrary, the old Stockholm SLC records indicate that only about 25 years into the revolution the oceans were being impacted by global warming (induced by a maddening increase in coal burning).
In Sweden's case, the SLC was sea level fall (SLF) caused by the melting of the Greenland Ice Sheet, and it is still ongoing (Proof of Concept - 5).
I may take a look at some of the other old records for more clues (PSMSL - Other Long Records).
The take home from this information is that the Arctic ice sheets had much more volume back then, and they were and are more sensitive to global warming than we have been led to believe (The Evolution of Models - 18).
They still are.
We are making a Titanic mistake if we fail to heed the warnings (Titanic Mistakes Using The W Compass, What Happened to the Iceberg That Sank the Titanic?).
