Last year's global concentrations of greenhouse gases carbon dioxide, methane and nitrous oxide reached their highest levels since pre-industrial times, the World Meteorological Organisation (WMO) said in an annual report on Monday.

These are the three most prevalent, long-lived, human-affected greenhouse gases in the atmosphere after water vapour, reports the organisation. Concentrations of most greenhouse gases continue to increase, it adds.

Since 1990, greenhouse gases have increased "radiative forcing", a measure of global warming, by 26%, the WMO says. Carbon dioxide is the most important greenhouse gas, contributing to nearly two-thirds of the increase in radiative forcing since 1750.
