Atmospheric CO2 recorded at Mauna Loa in Hawaii sets record

TUCSON, AZ (Tucson News Now) - We all know the green house gases have been on the rise for decades due to human development and natural reasons. We now have a new record for the amount of Carbon Dioxide in the Earth's atmosphere.

A measurement taken on the big island of Hawaii, on the top of Mauna Loa, has topped 400 parts per million (ppm). March, 2015 the average amount of Carbon Dioxide (CO2) in the atmosphere was 401.5 ppm. The first average taken back in 1953 was 315.7 ppm. That is an increase of 85 ppm or 27 percent more.

Evidence from ice caps indicates that CO2 levels may have been as low as 180 ppm back in prehistoric days. We are a far cry from those levels.

Mauna Loa is one of many places CO2 is measured around the globe. But it is considered one of the best locations due to its location. Mauna Loa is 11,000 feet above sea level and far from major human development. The air is considered natural and clean and can give us great measurements of the air.
