Carbon Dioxide Levels Reach Record High
Latest figures published in the US National Oceanic and Atmospheric Administration suggest that atmospheric carbon dioxide levels have reached a high not seen in 650,000 years. Levels now stand at 387 parts per million (ppm), which is 40% higher than levels seen during the industrial revolution.
There are now fears that anthropogenic induced climate change has spun out of control, given that the average rate of input of carbon dioxide into the atmosphere has been higher in the last seven years (2.1 ppm per year) compared to the 1970-2000 average of 1.5ppm per year. The last four years have seen incremental rises in input of carbon dioxide to the atmosphere, the chief greenhouse gas. This comes despite strong talk by governments on tackling climate change and stern advice from economists and top scientists concerning the imperative to reduce greenhouse gases. Some scientists now believe that this increase is down to the Earth losing its capacity to absorb the vast quantities of carbon dioxide being inputted to the atmosphere each year.
