In a lecture we learned that instantaneously removing all clouds from earth would give radiation forcing of about 18W/m² , leading to significant warming. So clouds, in simple words, cool the earth significantly.
However, in the same lecture we learned that clouds do have a positive feedback, which means (in my opinion), that by increasing temperature we have an increased amount of net radiation to earth. How is this to be understood? Does it mean that higher temperature gives rise to less clouds and therefore more net radiation?
Somehow, this appears not very intuitive, because on the one hand clouds are "good for cooling", on the other hand they have positive feedback, which is "worse for cooling". Is there a way to understand this "tradeoff" on a pure qualitative level?
I know, that clouds are quite complex and not well understood, but maybe there is a convincing explanation for that "discrepancy".
