Climate warning as CO2 levels spiral

Surging carbon dioxide levels have pushed greenhouse gases to record highs in the atmosphere, the World Meteorological Organisation has said.

Concentrations of carbon dioxide, the major cause of global warming, increased at their fastest rate for 30 years in 2013, despite warnings from the world’s scientists of the need to cut emissions to halt temperature rises.

Experts warned that the world was “running out of time” to reverse rising levels of carbon dioxide (CO2) to tackle climate change.
