Humanity manages to set all-time record for this dubious honor
California researchers say carbon dioxide levels in the Earth’s atmosphere have soared to a new high. In fact, HuffPost reports the level of CO2 is one never before been seen in human history. A daily CO2 reading by researchers on Saturday recorded a 415.26 parts per million baseline. Scientists from San Diego's Scripps Institution of Oceanography say it’s the first daily baseline to top 415 ppm in mankind’s history.
