This wonderful place, Wickford, RI, is my home. Its built environment have sat at sea level, surrounded by salt marshes for more than 350 years. At URI's Graduate School of Oceanography, we are working on #CoastalResilience solutions in the face of human-induced #sealevelchange #climatechange

It is pretty interesting to read some of the commentary on future sea level rise from the 1950s. This was from a symposium held in the Netherlands in 1954, before many of the aspects of climate change were fully understood, including Milankovich theory and CO₂ changes. #ClimateChange #SeaLevelChange

Commentary by Mr Bennema:

Dr. Pannekoek (Geolog. Survey) quotes some conclusions from Ahlmann's 1952 lecture in Washington. There are some indications that the climatic optimum in the Arctic of the past decades has passed its culmination point. This does not necessarily mean that a general glacier advance and lowering of the sealevel may be expected in the near future, the relation between climate and glacier regime being rather complex. Though some glaciers are advancing now, the majority are still retreating, and the sea-level is still rising.

Prof. Florschiitz (Leiden) also mentions the continuing glacier retreat in the Eastern Alps, whereas Prof. Bakker quotes the impression of Swiss, German and Austrian glaciologists, that the maximum of glacier retreat is now past.

Mr. van Weelden (B.P.M.) calls attention to Sir Edward Bullard's opinion about a deviation of the Gulf Stream towards the East by the accumula- tion of morainic material on the ridge in the Northern Atlantic, extending from Scotland to Greenland, which caused Greenland to become colder and Scandinavia warmer.

Prof. Rutten (Utrecht) mentions rhythmic glacier variations in Iceland similar to those known in Greenland, and presenting a periodicity like that mentioned by Mr. Bennema.

He thinks that the observations on the absence of glacier retreat in Antarctica are no reason for optimism. They only show that the recent rise of sealevel is entirely due to ice melting in the Northern hemisphere, and that, if Antarctic ice should also start retreating, the situation would be worse. There are, however, some other factors, possibly influencing climatic and sealevel changes, the study of which is recommended. They are:
