"Why is it going up? It's because mainly because we’re burning fossil fuels. We’re releasing all this extra carbon, and it’s building up in the atmosphere," a geochemistry professor at Scripps saidIt's like the Dow Jones. But instead of measuring the stock market, the Keeling Curve measures the amount of carbon dioxide in the atmosphere.
"There’s another Keeling now associated with the curve. That’s me," Keeling said."But it was originally named after my father.”Keeling is the son of Charles David Keeling, who started taking measurements of CO2 at Mauna Loa Observatory in Hawaii in 1958. At that point, CO2 levels were at 315 ppm. Since then, the number has gone up so fast that it's breaking records.
"The carbon dioxide has a natural cycle with higher values around May and lower values by the end of the summer, and this rise is superimposed on this," Keeling said."So we hit a record every year as we approach May. Even before May, we were breaking last year’s record.” In other words, scientists can determine if carbon dioxide comes from fossil fuels. But it does depend on the season, according to Keeling, and in El Nino years he says levels can go up faster.
