A new study by the UK Met Office suggests annual carbon dioxide levels in the atmosphere are set to shatter the symbolic barrier of 400 parts per million (ppm) this year and will not fall below it in our lifetime. The report adds that the likelihood of the threshold being breached a year ahead of expectations carries a warning for the future. The leap across the 400ppm watershed at the Hawaiian observatory will not change any climate change fundamentals. In an article published today on the website Carbon Brief, Dr Chris Field, director of climate monitoring at the Met Office, said: “While we have been expecting CO2 concentrations to increase over time, there has never To achieve that it will require a 40-70% cut in emissions by 2050, compared to 2010 levels, and zero emissions by the end of the century. However, despite the recent Paris Agreement and a boost in renewable energy, the world is still on track to overshoot this target.
