Carbon dioxide levels in the Earth’s atmosphere have been on the rise.
According to NOAA, last year global carbon dioxide growth was the fourth highest on record.
Carbon dioxide is a greenhouse gas that helps warm the planet by trapping heat from the Earth’s surface that would otherwise escape into space.
According to new data collected by NOAA’s Global Monitoring Division, carbon dioxide grew by 2.87 parts per million during 2018, jumping from an average of 407.05 parts per millions on January 1st, 2018 to 409.92 parts per million on January 1st, 2019. That was the fourth highest annual growth concentration of CO2 in 60 years of record keeping.
Three of the four highest increases have occurred in the past four years.
