Greenhouse gases hit record high

A UN agency has said the atmospheric levels of greenhouse gases are still on the rise.

The atmospheric concentration of carbon dioxide rose by about half a percent in 2005, the World Meteorological Organisation (WMO) has said. It said levels were likely to keep rising unless emissions were slashed. The most common greenhouse gas is water vapour, followed by carbon dioxide (CO2) nitrous oxide (N2O) and methane.

"There is no sign that N2O and CO2 are starting to level off," Geir Braathen, a senior scientist at the WMO told reporters.

"It looks like it will just continue like this for the foreseeable future."

Scientists say the accumulation of such gases - generated by burning fossil fuels such as coal, oil and gas - traps the Sun's rays and causes global temperatures to rise.

This is expected to lead to melting of polar ice caps and glaciers, rising sea levels and extreme weather such as storms and floods. ....
