Comments : Greenhouse gases rocketing at their fastest pace in almost 30 years!
Greenhouse gases found within the atmosphere have been compelled to record high levels due to the increasingly high measures of carbon dioxide; this had been stated by the World Meteorological Organisation.
Concentrations of carbon dioxide are seen to be a major cause of global warming having increased at their fastest rate for almost 30 years during 2013 despite multiple warnings from world scientists addressing the need to minimise or halt emissions in order to stop rising temperatures.
Due to the extortionately high levels of carbon dioxide, various officials have warned that the world could possibly be “running out of time” to reverse these rising levels of carbon dioxide in order to successfully tackle the existing changes in climate.
Between both 2012 and 2013 information collated has demonstrated that levels of gas have increased more so than any other year since 1984. This could be down to the minimal uptake of carbon dioxide by numerous ecosystems for example, forests although rising CO2 emissions could also be considered.
The World Meteorological Organisation have produced an annual greenhouse gas bulletin which shows the measurement in concentration of CO2 in the atmosphere stood at 142% of what they had originally been recorded at prior to the Industrial revolution.
Not only has carbon dioxide shown a major increase but other effective greenhouse gases have also taken a significant upsurge with concentrations of methane standing at 253% along with nitrous oxide also reaching 121% of pre-industrial levels.
In the time between both 1990 and 2013 the warming effect that had been taking place which is also known as “radiative forcing” had been solely due to greenhouse gases such as CO2 which is shown to have risen by more than a third which could also equate to 34%.
This particular bulletin exposes the concentrations of various gases that are held in the atmosphere whilst excluding emissions. Almost a quarter of these are absorbed by surrounding oceans depending on the area and an additional quarter by ecosystems.
Oceans are known to be the barrier when emission gases approach such as carbon dioxide which may otherwise be seen in the atmosphere, at a risk of many seas becoming increasingly acidic at a rate which hasn’t been seen for almost 300m years, the WMO stated.
WMO secretary-general Michel Jarraud mentioned;
“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. 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. We are running out of time. 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”.
Carbon dioxide is responsible for around four fifths of the increase in warming by greenhouse gases, with concentrations in the atmosphere seen to be averaging around 396 parts per million during 2013. During last year levels are seen to have increased by a sum of around 2.9ppm – the largest annual increase experienced since 1984 to 2013.
