Roger Revelle

and would soon get an important role to play in anchoring the global warming theory in mainstream science.

Revelle, who is viewed as the father of global warming, later said that he was kind of a pet of Death Bronx.

The conference led to the founding of the Population Council.

whose mission was to create a balance between the world's population and its resources by reducing birth rates, using contraceptives, sterilization, and the redistribution of the global population through international migration.

Rockefeller Foundation had been deeply involved in this experiment and supported the Kaiser Wilhelm Institute of Anthropology, Human Heredity and Eugenics in Berlin until the outbreak of the war.

Detlef Bronck had in March 1953 appointed the US National Committee to the International Geophysical Year.

including Roger Revelle and its initiator Lloyd Berkner.

The International Geophysical Year was a global scientific project aimed at achieving a deeper understanding of the earth system.

Callendar didn't settle the ocean question.

Roger Revelle and Hans Suess would give it a much stronger chemical and isotopic foundation in the 1950s.

But Callendar reopened a scientific case that many people thought had been closed.

He looked at the numbers and said, "The carbon is increasing, the temperature is increasing, and the industrial emissions are not politely disappearing into the sea." So by 1938, we are no longer talking about a purely theoretical future.

This was not a panic invented by modern environmental activists.

The physical case had been assembling for more than a century, and somebody had now found its fingerprints in the temperature record.

The American Institute of Physics History traces that progression through Callendar, while Revelle and Suess' later 1957 paper shows how the ocean question was taken apart more rigorously.

And it's interesting that scientists previously assumed that human influence on the climate only started in the mid-20th century, around the 1950s, relying on direct temperature records starting around 1880.
