Dismantling NOAA Threatens the World's Ability to Monitor Carbon Dioxide Levels

There are trillions upon trillions of numbers in the world. We use numbers to describe almost every conceivable thing in the universe. But there is one number that surpasses all others for the enormous impact it will have on every living thing on Earth over the next few thousand years. We consider it so important that we’ve dedicated our lives to acquiring and understanding it. Today that number happens to be: 427.6.

This is a measure (known in scientific terms as the mole fraction) of atmospheric carbon dioxide at the Mauna Loa Observatory in Hawaii, in parts per million. It’s part of a continuous chain of observations stretching back across two generations, to 1958, when Dave Keeling recorded the first measurement of 313 parts per million. Dave Keeling maintained this record, known as the Keeling Curve, using a running hodgepodge of short-term grants until 2005, at which point geochemist Ralph Keeling, a professor at UC San Diego’s Scripps Institution of Oceanography, coauthor of this piece and Dave’s son, assumed its stewardship. But now, after 67 years of battling to keep the program funded and provide the data to other scientists around the world, the program faces its most dire threat ever.

Why? Endeavors of this nature—highly precise measurements of a trace gas over many decades—require three basic inputs: knowledge, people, and money. It’s the third one that’s at risk, thanks to the current administration’s attacks on NOAA, the National Oceanic and Atmospheric Administration. NOAA provides support for our program both through an annual grant and through invaluable “in-kind” support, such as staffers taking samples for us, maintaining buildings in remote areas where sampling occurs, and running the Mauna Loa Observatory.
