Geneva (AFP) - Atmospheric carbon dioxide concentrations have crossed a new threshold, the UN's weather agency said Monday, highlighting the urgency of curbing manmade, climate-altering greenhouse gases.
In April, for the first time, the mean monthly CO2 concentration in the atmosphere topped 400 parts per million (ppm) throughout the northern hemisphere, which pollutes more than the south, the World Meteorological Organization (WMO) said.
"This should serve as yet another wakeup call about the constantly rising levels of greenhouse gases which are driving climate change," WMO chief Michel Jarraud said in a statement.
"If we are to preserve our planet for future generations, we need urgent action to curb new emissions of these heat-trapping gases. Time is running out," he warned.
Spring values in the northern hemisphere had previously spiked over the 400 ppm level, but this was the first time the monthly mean concentration of CO2 in the atmosphere exceeded the threshold.
The global annual average is set to exceed the 400 ppm level in 2015 or 2016, the agency added.

CO2 stays locked in the atmosphere for hundreds of years, and its lifespan in the oceans is longer still.

Peer-Reviewed Survey Finds Majority Of Scientists Skeptical Of Global Warming Crisis
It is becoming clear that not only do many scientists dispute the asserted global warming crisis, but these skeptical scientists may indeed form a scientific consensus.
Dont look now, but maybe a scientific consensus exists concerning global warming after all. Only 36 percent of geoscientists and engineers believe that humans are creating a global warming crisis, according to a survey reported in the peer-reviewed Organization Studies. By contrast, a strong majority of the 1,077 respondents believe that nature is the primary cause of recent global warming and/or that future global warming will not be a very serious problem.
