Carbon dioxide levels could reach their highest point in 50 million years by the end of the century

Continuing to burn fossil fuels at the current rate could bring atmospheric carbon dioxide to its highest concentration in 50 million years, jumping from about 400 parts per million now to more than 900 parts per million by the end of this century, a new study ["Future climate forcing potentially without precedent in the last 420 million years", 04 April 2017, http://www.nature.com/articles/ncomms14845 (full text)] warns.
And if greenhouse gas emissions continue unabated beyond that point, the climate could reach a warming state that hasn’t been seen in the past 420 million years.
Some research suggests that, if humans burned through all fossil fuels on Earth, atmospheric carbon dioxide concentrations could hit 5,000 parts per million by the year 2400.
