===Negative greenhouse effect===
Scientists have observed that, at times, there is a negative greenhouse effect over parts of Antarctica.<ref name="hsch">{{Cite journal |last1=Schmithüsen |first1=Holger |last2=Notholt |first2=Justus |last3=König-Langlo |first3=Gert |last4=Lemke |first4=Peter |last5=Jung |first5=Thomas |date=16 December 2015 |title=How increasing {{CO2}} leads to an increased negative greenhouse effect in Antarctica |journal=Geophysical Research Letters |language=en |volume=42 |issue=23 |doi=10.1002/2015GL066749 |issn=0094-8276 |s2cid=131351000 |doi-access=free}}</ref><ref name="sejas">{{cite journal |last1=Sejas |first1=S.A. |last2=Taylor |first2=P.

In this case, the rate of thermal radiation emission to space is greater than the rate at which thermal radiation is emitted by the surface. Thus, the local value of the greenhouse effect is negative.
