What examiners said
Some candidates thought that higher levels of carbon dioxide would lead to breathing difficulties due to a lack of oxygen in the air or that it would cause a hole in the ozone layer, neither of which gained credit. Other candidates gave vague references to pollution or described causes of the increase, like burning of fossil fuels. The link between atmospheric carbon dioxide concentration and glob...
