New data from US National Oceanographic and Atmospheric Administration (NOAA) confirms global carbon dioxide is at highest level for two million years.

Newly published data from NOAA has shown that in March 2015, the level of atmospheric carbon dioxide (CO2) across the globe stood at 400.83 parts per million.  For the same month in 2014, global atmospheric CO2 was at 398.1 parts per million.  Atmospheric CO2 concentrations have increased by over 120 parts per million since pre-Industrial times and alarmingly, half of that rise has happened since 1980.

As CO2 is a greenhouse gas that helps to cause climate change, we all need to take notice.  The world needs to work out ways of reducing our emissions of carbon dioxide and other greenhouse gases.  It's the only way that we can avoid more extreme weather, droughts, storms and floods in the future.

The world's leaders will be meeting in Paris in December 2015 to agree reductions in global emissions of CO2.  This new data from NOAA shows how important it is that they make proper commitments.
