Monitoring stations in the Arctic detect record levels of carbon dioxide, higher than ever above 'safe' 350ppm mark The world's air has reached what scientists call a troubling new milestone for carbon dioxide, the main global warming pollutant. Monitoring stations across the Arctic this spring are measuring more than 400 parts per million of the heat-trapping gas in the atmosphere.
