b.) While studies of ‘ice cores’ (drilled ice sheets more than 3 km deep in Antarctica and Greenland) show that from as far back as 800,000 years ago to until humans began burning fossil fuels – global CO2 levels rarely ever exceeded 300 ppm. [ 3 ] c.) With the latest data from the World Meteorological Organization (WMO) Greenhouse Gas Bulletin— we can compare the increase of CO2 concentrations in Earth’s atmosphere as follows: 2015 = 400.1 ppm 2016 = 403.3 ppm 2017 = 405.5 ppm 2018 = 408.5 – 411.0 ppm |
December 9, 2018, Not Distant, But ""Imminent"" Danger Of Irreversible & Irreparable Climate-Related: Calamities, Deaths and Losses Global CO2 (Carbon Dioxide) Levels Already Exceed 400 PPM (parts per million) ! 1.) In May 2018, scientific measurements of CO2 levels in Earth’s atmosphere exceeded 411 ppm – according to researchers at Scripps Institution of Oceanography in Hawaii, and the National Oceanic and Atmospheric Administration (NOAA). a.) When this scientific CO2 study program began 60 years ago—the first measurements were only 315 ppm. [ 1 ], [ 2 ] |
