Greenhouse gases hit new high

"Levels are at a new high," said Kim Holmen, research director of the Norwegian Polar Institute, which oversees the Zeppelin measuring station on the Arctic archipelago of Svalbard, about 1200 kilometres (750 miles) from the North Pole.

He said that concentrations of carbon dioxide, the main greenhouse gas, emitted largely by burning fossil fuels in power plants, factories and cars, had risen to 390 parts per million from 388 ppm a year ago.

Levels have hit peaks almost every year in recent decades and are far above 270 ppm level seen before the Industrial Revolution of the 18th century.
