Carbon dioxide concentrations and sea food

 

The politicians throughout the world aim to hold atmospheric carbon dioxide levels at 1990 levels – round about 375 parts per million. We have not seen any policies that would in any way do more than reduce the rate of carbon dioxide concentration by a small margin. We now stand at around 390 ppm and for the past few years the rate has increased by about 2ppm. There are signs that the rate of increase is falling to nearer 1.6 pmm but although the rate may be falling (perhaps partly due to economic recession which needs less fuel burning than economic prosperity) the atmospheric concentration is still rising. Here is why.
