According to United Nation’s World Meteorological Organization, the amount of greenhouse gases in the atmosphere reached a new record high in 2013, propelled by a surge in levels of carbon dioxide. This analysis was published in the World Meteorological Organization’s annual Greenhouse Gas Bulletin, which injected even greater urgency into the need for concerted international action against accelerating and potentially devastating climate change.

The Greenhouse Gas Bulletin showed that between 1990 and 2013 there was a 34% increase in radiative forcing – the warming effect on our climate – because of long-lived greenhouse gases such as carbon dioxide (CO2), methane and nitrous oxide.

In 2013, concentration of CO2 in the atmosphere was 142% of the pre-industrial era (1750), and of methane and nitrous oxide 253% and 121% respectively. CO2 concentrations rose 2.9 parts per million (ppm) between 2012 and 2013, the biggest annual increase since 1984.

Some scientists have been warning for years that the safe upper limit for atmospheric concentrations of carbon dioxide is no more than 350 ppm.

“We know without any doubt that our climate is changing and our weather is becoming more extreme due to human activities such as the burning of fossil fuels,” said WMO Secretary-General Michel Jarraud.

“The Greenhouse Gas Bulletin shows that, far from falling, the concentration of carbon dioxide in the atmosphere actually increased last year at the fastest rate for nearly 30 years. We must reverse this trend by cutting emissions of CO2 and other greenhouse gases across the board,” he said. “We are running out of time.”

co“Carbon dioxide remains in the atmosphere for many hundreds of years and in the ocean for even longer. Past, present and future CO2 emissions will have a cumulative impact on both global warming and ocean acidification. The laws of physics are non-negotiable,” Jarraud shared.

About a quarter of the total emissions are taken up by the oceans and another quarter by the biosphere, reducing in this way the amount of CO2 in the atmosphere.

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 report.

    BTW Look at Asok Asus, he posts the exact same thing over and over and over again. THis is CLEAR BIG OIL propaganda. Look at his old posts!!

    Look at this tool below me, saying that global warming isnt happening, WHo paid you? WHO Paid you?!?!?! =) I see a comment like this on every article about climate change= )

    Record high CO2 at the same time that there’s been no warming for
    19 years is very strong evidence disproving the theory that CO2 causes
    global temperatures to rise.

    Oh, and CO2 is not pollution.. It’s vital portion of our atmosphere. Plants require it to live and we require plants to live, both as factories for the O2 that we breath and
    for food for ourselves and our livestock.

    (BTW, I just LOVE the picture of those big evaporative cooling towers that are releasing NOTHING but harmless water vapor into the air. I suppose you believe that your ignorant readers will see those big, scary looking towers and assume they are releasing all kinds of nasty stuff into the environment.)

      Lol Tool of big oil, cant you find a real job? Commenting on every Climate Change article to say its not happening.. are you just this uneducated? Like you can’t handle even burger flipping?? Come on man go outside!
