Evidence is building that net cloud feedback is likely positive and unlikely to be strongly negative. (skepticalscience.com)
Actual physical observations have shown that net cloud feedback is very likely to be negative rather than strongly positive and that the net water vapor plus lapse rate feedback is around half of the amount estimated with assumed constant relative humidity. (judithcurry.com)
For instance, who is to say the LGM net cloud feedback wasn't strongly positive and the interglacial net cloud feedback somewhat negative? (julesandjames.blogspot.ru)
