What follows shares a glimpse of what our US Presidents before President Carter knew about the new climate change.

Climate Knowledge Before The Carter Administration

In 1955, the United States created the first climate modeling center, the geophysical fluid dynamics laboratory (GF DL) of the national oceanic and atmospheric administration (NOAA).

Atmospheric and ocean studies became increasingly important for national defense. Humanity's first satellite circled the Earth, a Soviet Union satellite, Sputnik. Overnight, the cold war increased science spending by a magnitude or so.

We knew and verified that our atmosphere intertwines with the global ocean. That's the nature of a wicked problem, as Earth systems continue to tell us to this day. We cannot do one thing to our environment without affecting something else in our environment.

That is how 1965 became a big year for federal government concerns in the new climate change.

Roger Ravel published his work on "atmospheric carbon dioxide." The White House warned that the harmful effects would occur by 2020, and these would cause ocean warming, sea-level rise, another dangerous change to our planet with increased fossil fuel use.

Even the Department of Commerce got into the show in 1965. The Department reported that "studying the CO2 content of the atmosphere" and "monitoring stratospheric temperature" became their plans for the fiscal year 1967.

On December 20, 1965, National Science Foundation published the "weather and climate modification: report of the special commission on weather modification." This document estimated that the CO2 concentration in the atmosphere increased 10 to 15% in the 20th century. Mind you; this is 1965. As a result, significant changes have occurred to her seat balance. I'm leaving a link to this comment below in the description.

The National Science Foundation created the National Center for atmospheric research (in CAR) in Boulder, Colorado. And if that wasn't enough to impress our grandparents, UCLA began a modeling laboratory. Interestingly the Rand Corporation also began a climate modification for military applications. So plenty is going on in the United States when it comes to developing climate science and climate science models by the US government, US military, and university level studies.

During the 1930s through the 1970s, climate scientists would become concerned about climate change.

By the time President Carter arrived as the US president, climate change produced by human activities had become a growing concern.

Computer modeling became more powerful. Verification climate models with computers showed strong comparisons between atmospheric carbon dioxide density and planetary warming.
Keeling showed that seasonal carbon dioxide concentrations in the northern hemisphere were 315 ppm. As a result, the famous "Keeling curve" became a common feature of atmospheric carbon dioxide measurements.

He showed how atmospheric carbon dioxide density in the atmosphere kept pace with the changing seasons in photosynthesis. As spring mirrored, CO2 density decreased along with photosynthesis increases. The opposite occurred in the fall as photosynthesis slowed and CO2 densities decreased.
