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."
