Mongabay: For the first time since homo sapiens evolved, concentrations of carbon dioxide in the atmosphere have struck 400 parts per million (ppm) due to burning fossil fuels. The National Oceanic and Atmospheric Administration (NOAA) reports that readings of carbon dioxide at Mauna Loa Observatory in Hawaii hit the symbolic number on Thursday and are expected to continue rising in coming years. The last time concentrations were this high for a sustained period was 4-5 million years ago when sea levels were...

Australian Broadcasting Corporation: Global greenhouse gases in the atmosphere have reached an ominous milestone that's unprecedented in recorded human history. At the Mauna Loa observatory in Hawaii, the daily reading of carbon concentrations has now reached a level that hasn't been seen in more than 3 million years: CO2 levels in the atmosphere have hit 400 parts per million. The last time it reached a level like this, temperatures rose from between three and four degrees and sea levels were between five and 40 metres higher...

CNN: In some ways, it's just a number, but it's a big number with enormous implications. For the first time, scientists measured an average concentration of atmospheric carbon dioxide of 400 parts per million in Mauna Loa, Hawaii, where the National Oceanic and Atmospheric Administration observatory is located, on Thursday. "Most experts that really study CO2 amounts estimate that we haven't seen that amount of CO2 in our atmosphere in about 3 million years," said J. Marshall Shepherd, climate change...

Bloomberg: The amount of carbon dioxide in the atmosphere surpassed a threshold not seen for 3 million years, exceeding 400 parts per million for the first time since researchers began tracking the data. The main greenhouse gas blamed for global warming averaged 400.03 parts per million at the U.S. National Oceanic and Atmospheric Administrations Mauna Loa monitoring station in Hawaii on May 9, the agency said yesterday. The level is considered a landmark by scientists and environmentalists, who say...
