CO2 levels just reached 410 ppm – the highest in millions of years

EL SEGUNDO, CALIFORNIA (inhabitat.com) - Remember when carbon dioxide (CO2) levels in the atmosphere hit a terrifying 400 parts per million (ppm)? That’s number’s old news now – concentrations just reached 410 ppm for the first time in millions of years. Last week, researchers at Mauna Loa Observatory in Hawaii recorded the record-breaking level, and scientists warn the rate of increase will only slow when we reduce our carbon emissions.

Mauna Loa Observatory scientists just recorded the first CO2 level above 410 ppm since they began recording in 1958. Back then, the first atmospheric CO2 concentration was a mere 313 ppm. In 2013 concentrations hit 400 ppm. Last week’s reading was 410.28 ppm.

University of Southampton professor of isotope geochemistry Gavin Foster told Climate Central, “It’s pretty depressing that it’s only a couple of years since the 400 ppm milestone was toppled. These milestones are just numbers, but they give us an opportunity to pause and take stock and act as useful yard sticks for comparisons to the geological record.”

The United Kingdom Met Office put out a CO2 forecast for the first time ever earlier in 2017, and it turned out to be pretty close to reality; they predicted CO2 concentrations could breach 410 ppm in March but very likely would by April.

El Niño is partly at fault for spiking levels of CO2, but more than natural factors, humans burning fossil fuels are to blame. National Oceanic and Atmospheric Administration (NOAA) atmospheric scientist Pieter Tans said, “The rate of increase will go down when emissions decrease. But carbon dioxide will still be going up, albeit more slowly. Only when emissions are cut in half will atmospheric carbon dioxide level off initially.”

In a March NOAA article, Tans said the rate of CO2 growth over the last 10 years is 100 to 200 times quicker than the rate Earth saw as it transitioned out of the Ice Age, saying “This is a real shock to the atmosphere.”
