Red dwarf (MV) stars comprise > 70% of all stars in our Galaxy, but were traditionally dismissed as suitable primaries for supporting habitable planets. Extreme climates associated with slow or synchronous rotation, reduced photosynthetic potential of red dwarf sunlight and frequent flare activity have been cited as problematic. Working in conjunction with climatologists, we were able to demonstrate that these concerns were over-pessimistic, a view generally endorsed in the period 1994 to 2007. 2007 to 2010 saw valuable new studies and critical re-appraisal from other workers, who raised new problems, such as atmospheric erosion by stellar winds. Habitable planets of MV stars remain a possibility.
