Levels of carbon dioxide in the atmosphere have risen by a record amount in the past 12 months raising fears that global warming may be accelerating out of control. This according to a report in the Independent of London.

The data is based on measurements by US government scientists. Scientists have found that the level of carbon dioxide in the atmosphere has risen sharply in each of the past three years. Some scientists fear this shows that global warming is feeding itself with rising temperatures causing increases in carbon dioxide which then helps drive the temperatures even higher.
