Human activity has once again driven the atmospheric concentration of carbon dioxide to a new high — and the isotopes prove it. The latest Greenhouse Gas Bulletin put out by the World Meteorological Organization said its concentration in 2018 clocked in at 407.8 parts per million, “or 147% of pre-industrial levels in 1750,” the UN body said in a statement Monday. Advertisement “This continuing long-term trend means that future generations will be confronted with increasingly severe impacts of climate change, including rising temperatures, more extreme weather, water stress, sea level rise and disruption to marine and land ecosystems,” researchers said in the press release. “CO2 remains in the atmosphere for centuries and in the oceans for even longer.” Moreover, the meteorological group said, the 2017-18 increase surpassed the past decade’s average growth rate. The report differentiates between concentrations of warming gases and emissions, as BBC News explained. Emissions are the amount of gases discharged into the atmosphere, while concentrations are what the air contains after the emissions are absorbed by oceans, land and trees, BBC News said.
