This story came out a fortnight ago on The Guardian and it shows that the levels of carbon dioxide across the world have continued to increase. The concentration of CO2 in the atmosphere has reached 399.72 parts per million (ppm) and is likely to pass the symbolically important 400ppm level for the first time in the next few days.
This is unprecedented but the finding has been supported by the Mauna Loa station in Hawaii. The station sits 3400m above sea level and far away from any other pollution sources. As a result, it has long been considered to be the standard bearer in measuring atmospheric CO2 levels.
Our reliance on fossil fuels has contributed greatly to the rise of carbon levels in the atmosphere. Unfortunately, it doesn’t look like there is a solution in sight. At the moment countries involved in climate talks remain deadlocked, and no global agreement to reduce emissions is expected until 2015.
As a point of interest, The Keeling Curve reports that the last time temperatures were this high was 3-5 million years ago in the Pliocene era! Personally speaking, I’m not ready to go extinct like the mammals of that era. Whether you believe in climate change or not, this should be a wake up call fo everyone to embrace cleaner, greener and more efficient forms of energy.
