A study by WMO (World Meteorological Organization) has resulted in the report that the levels of carbon dioxide in the U.S. in 2011 rose to 339.9 ppm (parts per million) which is up two ppm’s from the 2010 levels. The shocking part about this is that it is known that carbon dioxide is the single most important contributor to greenhouse gasses. The world has watched since the 1990’s as the rise of carbon dioxide output as increased at an average rate of 1.5 ppm. The 2011 level has kept in line with the average increase per year, but, considering the focus on reduction, we should be experiencing a downtrend in pollution. The 2011 level now brings the overall increase level to thirty percent, since 1990.
The WMO indicated that humans began contributing higher carbon emissions with the beginning of the industrial revolution in 1750. Half of the contributing effects were being absorbed by carbon sinks, but the natural process of carbon storage facilities such as forests and oceans cannot continue in our future. In essence, there is a maximum amount that can be processed naturally, and then it goes into overdrive. The oceans are already increasing in the acidic levels and this is affecting the underwater coral reefs and food chains.
The Swiss-based U.N. agency, that uses the input data from over fifty countries, has compiled a report with details stating that there is a rise of other greenhouse gasses including nitrous oxide and methane. According to WMO, approximately 60% of the methane that is released into the atmosphere is derived from human activities such as fossil fuel exploitation, rice agriculture, farming, biomass burning and landfills. The 2011 data is showing that these concentrations achieved a new high point of 1813 ppb (parts per billion), which is 259% higher than our pre-industrial levels. Nitrous oxide emissions are contributed by human activity at 40%, 324.2 ppb, which is up one ppb from the 2010 numbers and 120% higher than our pre-industrial timeline.
