Summary:
The human-caused rise in atmospheric concentration of carbon dioxide is being given an extra boost this year by the natural climate phenomena of El Niño, say climate scientists in a paper published in today's edition of the journal Nature Climate Change. As a result, 2016 will be the first year with concentrations above 400 parts per million all year round in the iconic Mauna Loa carbon dioxide record.
