The burning of wood (should be reduced to a greater extent) releases
oxidizable carbon to the atmosphere whose presence in greater amount
causes the elevation of temperature.
There is strong evidence that emissions of chlorofluorocarbons (CFCs)
were the major cause of the recent abnormal warming. Like carbon CFC
do not trap heat but in the presence of UV rays the chlorine gets
detached from CFC, drifts up into the stratosphere and these unattached
chlorines catalytically convert Ozone molecules into Oxygen molecules
depleting the ozone layer.
