This is because firstly, the micro-organisms that break down dead trees produce copious amounts of CO2, and secondly, there is less vegetation remaining that can remove the greenhouse gas from the air by capturing the carbon in leaves, trunks and roots as part of its growth cycle.

Without roots to hold the soil in place, rivers and streams washed most of the dead vegetation to the sea where it then blocked the sun's light and sucked up all the oxygen.
