The “Present Climatic Fluctuation” paper was presented at the meeting of the Royal Geographical Society on 3 May, 1948; it contains practically all evidence of climate change that we are aware of now (e.g. melting of Kilimanjaro, polar bears, Arctic ice, weather patterns, migration of species, etc.). Hans Ahlmann was a geographer with a broad field experience in Arctic and Antarctic.

Question: what Ahlmann did not know then?

Answer: The Keelng’s Curve

Charles David Keeling, started measurements in 1958, introduced first evidence of  the measured “anthropogenic” (or “human caused)”) effect from carbon dioxide, proposed by Svante Arrhenius in 1896. This was his post-doc topic of research at Scripps Oceanographic Institute in La Jolla, CA.
