More carbon dioxide was emitted into our atmosphere between 2012 and 2013 than in any other year since 1984, putting humans on the fast track toward irreversible global warming, the United Nation's weather agency said in a report released Tuesday.

The World Meteorological Organization's (WMO) annual Greenhouse Gas Bulletin showed that the increase of atmospheric CO2 from 2012 to 2013 was 2.9 parts per million (ppm), the largest year-to-year increase in 30 years. Because of that growth, the average amount of CO2 in the atmosphere reached 396 ppm - just 9 ppm away from an average level some scientists believe could cause enough sea level rise, drought, and severe weather to significantly harm human populations across the globe.

"The Greenhouse Gas Bulletin shows that, far from falling, the concentration of carbon dioxide in the atmosphere actually increased last year at the fastest rate for nearly 30 years," WMO Secretary General Michel Jarraud said in a statement. "We must reverse this trend by cutting emissions of CO2 and other greenhouse gases across the board. We are running out of time."
