worldwide temperatures are n’t the only thingrising faster than anyone can retrieve . The same function for the concentration of CO2 in the atmosphere , according to thelatest dispatchfrom the Mauna Loa Climate Observatory in Hawaii . It ’s almost as if the two phenomena are related or something .
From February 2015 to February 2016 , the atmospherical carbon concentration at Mauna Loa — long held as the bench mark for world-wide CO2 degree — rise 3.76 part per million , tick off the large increase in a 12 - month period since the noted Keeling Curve began in 1958 . The previous record for a 12 - month CO2 increase was made in 1997 - 1998 , when atmospheric carbon concentrations uprise 2.82 ppm . That was also the only yr in history with an El Niño event that can quantify up tothis twelvemonth ’s Godzilla Niño .
In 2013 , globular atmospheric CO2 engrossment rose above 400 ppm for the first time inapproximately 3 million years . Since then , we ’ve been strike that400 ppm milestone earlierwith each surpass year .
One could fence that 400 ppm , as well as the 2 level Anders Celsius warming milestonewe of late surpass in the northerly hemisphere , are just that : milestones . They are . Soon , the 24-hour interval when CO2 absorption ever descend below 400 ppm will be behind us , mark a key shimmy in our ambiance that will persist for thousands of years to come . What ’s scarey is the future these milestones typify — and how quickly we seem to be blow past them with very few mass pack note .
