GENEVA / GREENHOUSE GASES

09-Sep-2014 00:01:44
The World Meteorological Organization (WMO) warned of the record high in the level of greenhouse gases in the atmosphere in 2013. WMO said that CO2 levels increased more between 2012 and 2013 than during any other year since 1984, possibly due to reduced CO2 uptake by the earth’s biosphere and steadily increasing CO2 emissions.

3. SOUNDBITE (English), Michel Jarraud, Secretary-General, World Meteorological Organization:
“For CO2 the rate of increase is the largest of the last 30 years, at least. So this is not good news because it’s not only business as usual but the concentration increased even faster.”

5. SOUNDBITE (English), Oksana Tarasova, Chief, Atmospheric Environment Research Division, World Meteorological Organization:
“We need some time to quantify what has happened this year but the preliminary analysis shows that it is very likely to be the decreased uptake by the biosphere because the biosphere takes up lighter CO2 than the ocean.”

7. SOUNDBITE (English), Michel Jarraud, Secretary-General, World Meteorological Organization:
“Time is not on our side for sure. The more we wait, the more challenging it will be because every year passing, concentrations are, and this is factual, we observe that, with great accuracy, concentrations are reaching a higher and higher value.”

9. SOUNDBITE (English), Oksana Tarasova, Chief, Atmospheric Environment Research Division, World Meteorological Organization:
“The growth rate is increasing exponentially. So between 2000 and 2010, the average increase was roughly 2 ppm per year, between 1990 and 2000, the increase was 1.5 ppm per year. The decade before it was 1 ppm per year. So, it is increasing also exponentially.”

STORYLINE

The level of greenhouse gases in the atmosphere reached a record high in 2013, due to a surge in levels of carbon dioxide, according to the annual Greenhouse Gas Bulletin from the World Meteorological Organization (WMO).

WMO says that CO2 levels increased more between 2012 and 2013 than during any other year since 1984. More research needs to be done but preliminary data indicates that the increase was possibly due to reduced CO2 uptake by the earth’s biosphere and steadily increasing CO2 emissions.

The bulletin showed that between 1990 and 2013 there was a 34 percent increase in the warming effect on the climate, because of long-lived greenhouse gases such as carbon dioxide, methane and nitrous oxide.

In 2013, the global amount of carbon dioxide in the atmosphere reached 396 parts per million (ppm), an increase of 2.9 ppm compared with 2012.

A senior official of the World Meteorological Organization, Oksana Tarasova, said that the concentration of carbon dioxide in the atmosphere is growing “exponentially.”

She said that between 2000 and 2010, “the average increase was roughly 2 ppm per year,” whereas between 1990 and 2000, it was 1.5 ppm per year. She noted that the decade before the global amount of carbon dioxide in the atmosphere increased by 1 ppm per year.

The Greenhouse Gas Bulletin reports on atmospheric concentrations – and not emissions - of greenhouse gases. Concentrations represent what remains in the atmosphere after the complex system of interactions between the atmosphere, biosphere and the oceans. About a quarter of the total emissions are taken up by the oceans and another quarter by the biosphere.

The ocean cushions the increase in CO2 that would otherwise occur in the atmosphere, but with far-reaching impacts. The current rate of ocean acidification appears unprecedented at least over the last 300 million years, according to an analysis in the bulletin.
