#Regram #RG @wmo_omm: Levels of heat-trapping greenhouse gases in the atmosphere have reached a new record high. 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. Today we released the Greenhouse Gas Bulletin which showed that globally averaged concentrations of carbon dioxide (CO2) reached 407.8 parts per million in 2018, up from 405.5 parts per million in 2017.
