The National Institute of Polar Research (NIPR) announced on July 12 that atmospheric concentrations of carbon dioxide at the Syowa Station topped 400.06 ppm on May 14 for the first time since it began data observation in 1984.

 

The CO2 concentration level of 400 ppm is being observed in various parts of the world. The latest data recorded in the Japanese Antarctic research facility proves that sources of CO2 emissions are moving beyond the northern hemisphere, underscoring how serious global warming is becoming.

 

According to the NIPR, the CO2 concentration in the Syowa base averaged at 400.51 ppm in June. The average concentration of CO2 was about 398 ppm last year. The level of atmospheric concentration of CO2 has been increasing at an annual pace of 2 ppm over the last decade. It is projected that the annual average will exceed 400 ppm this year or next year.
