Global levels of CO2 crossed the 400 ppm "benchmark" in 2015
The World Meteorological Organisation(WMO) has published the "WMO Greenhouse Gas Bulletin" where they alert that Levels of CO2 in the atmosphere have reached another new record high. The last bulletin of this organization underlinethat globally averaged concentrations of CO2 reached 407.8 parts per million in 2018, up from 405.5 ppm in 2017. Global levels of CO2 crossed the 400 ppm "benchmark" in 2015.
WMO shows how future generations will have to confront the severe impacts of climate change, including rising temperatures, more extreme weather, water stress, sea level rise and disruption to marine and land ecosystems.
Inger Andersen, executive director of the UN Environment Programme (UNEP) has pointed: "The findings of WMO's Greenhouse Gas Bulletin and UNEP's Emissions Gap Report point us in a clear direction -in this critical period, the world must deliver concrete, stepped-up action on emissions. We face a stark choice: set in motion the radical transformations we need now, or face the consequences of a planet radically altered by climate change."
