Global warming gases have increased beyond the worst predictions of the UN's climate experts - exceeding the worst of seven emissions predictions laid down by the UN's World Meteorological Organisations.

Weather stations in the Andes, in Alaska and the south Pacific helped to gather the data, which showed surges in various 'greenhouse' gases, including gases used as replacements for the CFCs previously blamed for eroding the ozone layer.

Nitrous oxide - released by fertilisers, as well as tropical soils and oceans - is also emerging as a potent greenhouse gas. Carbon dioxide levels have also surged.

The WMO said that we need to further understand how so-called 'greenhouse gases' interact with Earth's natural cycles, the biosphere and oceans. Global warming gases are at record levels from emissions, the UN's weather agency has warned.

The World Meteorological Organisation said heat-trapping carbon dioxide concentrations in the air have increased by 39 per cent to 389 parts per million - the highest concentrations since the start of the industrial era in 1750.

The rate of increase has accelerated, according to the World Meteorological Organization’s Greenhouse Gas Bulletin. It focused special attention on rising nitrous oxide concentrations.
