[font size=4]Global carbon dioxide concentrations surpass 400 parts per million for the first month since measurements began[/font]
Wednesday, May 06, 2015
[font size=3]For the first time since we began tracking carbon dioxide in the global atmosphere, the monthly global average concentration of this greenhouse gas surpassed 400 parts per million in March 2015, according to NOAAs latest results.
It was only a matter of time that we would average 400 parts per million globally, said Pieter Tans, lead scientist of NOAAs Global Greenhouse Gas Reference Network. We first reported 400 ppm when all of our Arctic sites reached that value in the spring of 2012. In 2013 the record at NOAAs Mauna Loa Observatory first crossed the 400 ppm threshold. Reaching 400 parts per million as a global average is a significant milestone.
This marks the fact that humans burning fossil fuels have caused global carbon dioxide concentrations to rise more than 120 parts per million since pre-industrial times, added Tans. Half of that rise has occurred since 1980.
The International Energy Agency reported on March 13 that the growth of global emissions from fossil fuel burning stalled in 2014, remaining at the same levels as 2013. Stabilizing the rate of emissions is not enough to avert climate change, however. NOAA data show that the average growth rate of carbon dioxide concentration in the atmosphere from 2012 to 2014 was 2.25 ppm per year, the highest ever recorded over three consecutive years.
