Description:
CO2 is the strongest anthropogenic forcing agent for climate change since
pre-industrial times. Like other greenhouse gases, CO2 absorbs terrestrial
surface radiation and causes emission from the atmosphere to space. As
the surface is generally warmer than the atmosphere, the total long-wave
emission to space is commonly less than the surface emission. However,
this does not hold true for the high elevated areas of central Antarctica. For
this region, it is shown that the greenhouse effect of CO2 is around zero or
even negative. Moreover, for central Antarctica an increase in CO2
concentration leads to an increased long-wave energy loss to space, which
cools the earth-atmosphere system. These unique findings for central
Antarctica are in contrast to the well known general warming effect of
increasing CO2. The work contributes to explain the non-warming of central
Antarctica since 1957.
